What to Decide Before Choosing a “Buzzing” Machine

A vibration machine is a home fitness device that shakes your body with vibration, whether you stand on it, sit on it, or rest your feet or hands on it. It stays popular because it is so easy to use: step on it while watching TV or between chores. But the first stumbling block when choosing one is usually not the vibration strength (how many levels) or how big it looks. It is which posture you will use it in (standing, sitting, or just one body part), and whether it is a machine you can use comfortably without strain. Settle these two points first and your shortlist gets surprisingly short.

There is one more thing you cannot skip when choosing this product: the vibration type. Even among “buzzing” machines, ones that only move up and down, ones that swing side to side, and multi-directional (3D) ones that combine both feel completely different and suit different ways of use. If you choose only by price range or design, it is easy to end up regretting that the shaking is not what you expected.

💡

Roadmap for this article: First understand the differences in vibration type, then decide which posture type (standing / sitting / one body part) suits you. After that, check level adjustment, noise level, weight capacity, and safety features, then look at when to buy and common regrets. Note that a vibration machine is not a device that makes you lose weight or build muscle just by standing on it; it is a prompt and a support for moving your body. Results vary from person to person, and people with medical conditions, pregnant women, older adults, and others should consult a doctor before use.

Vibration type changes how it feels (this is the core of the product)

What people overlook most, and what affects satisfaction most, when choosing a vibration machine is how it shakes. In catalogs, numbers like “3D vibration” and “up to 99 levels” stand out, but once you understand the differences in type, you can see which model you actually need.

Vibration typeHow it movesFeel and who it suits
Up and down (vibration)The platform vibrates finely, straight up and downFine, fast shaking. For people who want to stand and shake the whole body in small, quick movements
Side to side / swinging (oscillation)Tilts left and right like a seesawA larger, slower motion with a gentle shaken feeling
3D / multi-directionalCombines up-down, left-right and front-backThe stimulation varies. For people who tire easily of the same motion
Seat / footrest vibrationThe seat or the foot platform vibratesReaches the legs, hips and soles without standing. For people who want to use it gently

Also keep in mind that more levels does not mean higher performance. Even with 99 levels, most people actually use only a few. What matters more for sticking with it than the number of levels is how gentle the low end is, and whether the steps between levels feel comfortable to you. If you have a chance to try one, be sure to check how gentle the weakest setting is and how intense the strongest is.

Stronger vibration does not mean it works better

Do not assume that stronger vibration is more effective. Vibration that is too strong can cause dizziness, discomfort and strain on the body. Neither type nor strength guarantees any “effect”; all of it is only an aid to exercise. What ultimately matters is finding a vibration that feels good and that you can keep using without strain.

Standing, sitting or one body part: which posture will you use?

After vibration type, the next thing to decide is where on the body and how the vibration is applied, that is, your posture. If you settle this first, the priorities for size and safety features follow naturally.

Posture typeFeaturesWho it suits
Stand on it (whole body)You stand on the platform and shake the whole body. Large presencePeople who want to move the whole body easily and exercise while doing something else
Use while seatedPlaced on a chair or the floor; you sit and apply it to the legs and hipsPeople who feel unsure about standing or worry about wobbling
Footrest / compactUses a foot platform or a hand-sized unit for one body part; saves spaceFor the soles or one area; can even go under a desk

If standing worries you, do not force yourself into a whole-body type

The image of a vibration machine is strongly “something you stand on,” but if you worry about wobbling or feel unsteady on your legs, a type you can use seated or a compact footrest type will feel safer and be easier to keep using. Standing whole-body types have a big presence and a real risk of falling, so there is no need to start there. Being honest about your own strength and sense of balance is the key to using it for a long time without injury.

📝

Older adults and people who are unsure about exercise should start with a seated type, in a setting with a handrail or support, at low vibration and with care. If you have weak bones or joints or worry about conditions such as osteoporosis, vibration can be a strain on the body, so consult a doctor before use.

In an apartment, sound and vibration traveling through the floor matter most

Unlike other appliances, a vibration machine by its very design sends vibration into the floor. In apartment buildings, how much it is heard downstairs tends to be the biggest practical issue, more than the machine’s specs. Buying one and then finding you cannot use it at night, or that you cannot keep going because you worry about the people below, defeats the purpose. Choose by working backward from where you will set it up.

  • Choose a model that advertises quiet design: Even within the same posture type, standing whole-body types vibrate more strongly. In an apartment, seated types, compact ones and those with high quietness are the safer choice.
  • Always use an anti-vibration mat: Just laying an anti-vibration, soundproof mat under the unit changes how much reaches the floor. Consider this basic equipment even for quiet models.
  • Mind the time of day: Avoid late night and early morning, and use it when it blends into everyday noise. A timer also helps prevent overuse.

In a house, the same measures help for family members or housemates who are sleeping. Quietness is hard to judge from catalog numbers alone, so checking reviews for what people say about the real sound and vibration is the realistic approach.

Checking weight capacity, size and safety features

Once the direction on type, posture and quietness is set, finish by pinning down the practical specs. They are unglamorous, but missing them leads to regrets such as “it does not fit,” “it broke quickly,” or “it is too scary to use.”

Weight capacity and size

For types you stand on, choose a weight capacity with room to spare over your body weight. Being right at the limit leaves concerns about breakdown and safety. The unit takes up a fair amount of space, so check where it will go both when in use and when stored. A slim model with casters is easy to take out and put away, and in the end that decides whether you keep using it. Seated types and compact footrest types save space and have the advantage for storage.

Safety features that give peace of mind

  • Handrail and non-slip surface: For standing whole-body types, a handrail you can hold and a non-slip surface underfoot lower the risk of falling.
  • A start that does not suddenly get stronger: A strong vibration the moment you switch on is dangerous. A type that ramps up gradually is safer.
  • Timer: Overuse leads to dizziness and strain. A timer that stops automatically is useful as a safety device.
  • Remote control and foot-position guide: Being able to change strength and mode at hand, and knowing where to place your feet, makes it easier to avoid awkward postures.

Five items to check on a product page, from the top, and what happens if you miss them

On a vibration machine, the order of the spec table does not match the order that actually affects how it feels. Many product pages lead with big numbers (the number of vibration levels or an image of calories burned), but those numbers often have little to do with satisfaction after you buy. Here we rearrange the order in which to check.

  1. First, look for the vibration typeCheck whether the text says which of “up-down vibration,” “side-to-side (swing) vibration,” or “3D (combined)” it is. A product page that does not say may be vague about the type and push only “vibration level ◯ steps.” If the type is wrong, you get the least reversible kind of dissatisfaction: you wanted a quiet ride but your body is shaken hard, or you wanted more stimulation and it feels lacking.
  2. Plate size and the width where you can place your feetThe length and width of the top plate in centimeters are different from the size of the flat area where you can actually put your feet. On models with a handrail, the base of the post can protrude onto the plate, so the foot area is narrower than the catalog size. If you do not check this, after delivery you find that standing at shoulder width puts the outside of your feet over the edge, your stance is unstable and you end up not using it.
  3. Height of the unit (from the floor to the plate)It is a difference of a few centimeters, but it matters in rooms with low ceilings or depending on where you watch TV. When standing, the unit’s height adds to your own. Ignore this and you may run into layout problems like hitting the light or the top of the doorway with your head once you step on.
  4. Weight capacity and the “at rest / in use” wordingA weight capacity means something different depending on whether it is the value at rest or during vibration. If you choose a model whose number is close to your weight, with no margin the shaking can feel sluggish or the motor can get louder. If the machine is shared by the family, choose a value with a clear margin over the weight of the heaviest person.
  5. Power supply and cord lengthIs it an AC adapter type or a direct-connect type, and how many meters is the cord? If you do not check, the outlet will not reach where you want to use it and you will end up adding an extension cord. You do not want a cord running under a vibrating machine, so the safe order is to decide where to put it first and then check the cord length.

Information you can only read from the photos

Some things are not in the spec table but become clear when you look closely at the photos. The number and size of the (rubber) feet directly affect how much reaches the floor. A model with only four small feet and one that sits flat on its whole surface will transmit differently to the floor below, even at the same vibration. Also important is where the control panel is on the plate. If the controls are at your feet when you stand on it, it is hard to reach during operation and you end up depending on the remote. It is reassuring to check as well whether a remote is included, whether it uses batteries, and what you would do if you lose it.

💡

A figure like “vibration level ◯◯ steps” does not guarantee the maximum strength or how fine the steps are. Even with many steps, it is common that you actually use only the lowest few. More than the number of steps, whether the weakest step is really weak (that is, whether you can keep using it) affects everyday usability.

What to pick up from reviews

When reading reviews, it helps to look first not at the star rating but at posts that state how many days since setup and whether the person lives in an apartment building. Complaints about vibration machines tend to appear not on day one but a few weeks later. Specifically, posts that describe changes in how it is used, such as “it is louder than I expected and I can’t use it at night,” “I added a mat,” or “I stopped using it standing and now use it seated,” are the most useful. On the other hand, a post like “I tried it right after it arrived, it feels great” tells you almost nothing about whether you can keep using it.

💡

For models that need assembly, also check whether attaching the post requires tools and whether it is light enough for one person to lift. A heavier unit tends to vibrate more stably, but lifting it to move it or clean around it after setup becomes a burden. If you plan to stand it upright to store it when not in use, weight is something to check first.

Living alone, sharing with family, little space: the right answer depends on your situation

Whether a vibration machine suits you depends more on where you put it, who uses it and how often than on body type or exercise goals. The same product can get opposite evaluations in different environments. Here are the typical patterns.

Living alone in an apartment building, with time only at night

Under these conditions, you will have fewer regrets if you put how little it transmits downward ahead of vibration strength. In terms of type, swing types that sway slowly side to side tend to give a gentler thump to the floor than types that hit hard up and down. Also, using it seated with only your feet on it spreads your weight more softly than standing on it with your whole body, which means less load on the floor below. What to avoid is buying a high-output model that advertises “powerful” and “high speed,” and then being able to use it only at the weakest level. Paying for top strength is pointless when you never get to use it in an apartment at night.

Sharing with family

The issue when sharing is not the difference in body weight but carrying over the settings. If the next person steps on at the strength the previous person used, the unexpected shaking can startle them and throw them off balance. Whether it always starts from the weakest when you power it on again, or remembers the last setting, makes a surprisingly big difference when shared. Also, the basic rule is to match the weight capacity to the heaviest person and leave a margin. A model with a handrail lets family members of different builds change where they hold on, which widens the range of people who can use it steadily. What to avoid is a small, lightweight model designed for one person’s build being passed around the whole family. When the unit is light, it can slide out of position when a heavier person gets on.

Little space, taking it out and putting it away every time

If you will store it, the criterion shifts from “performance” to how many actions it takes to take it out and put it away. Models with a handrail are stable, but a post means you cannot slip it into a gap for storage. In that case, a slim plate-only model light enough to stand up with one hand is realistic. However, slim, light models tend to shift along with the vibration, so always think of them together with a non-slip mat. What to avoid is a model that says “can be stored” but in practice is so heavy that you need both hands to move it. Once taking it out becomes a hassle, how often you use it will surely drop.

Rarely used, just want to try it

If you expect to use it fewer than a few times a week, a feature-rich model in the upper price range is likely to be more than you can use. Even with several program modes built in, occasional users use almost only manual, constant operation. For this group, starting with an entry-level compact seated type and moving up to a more serious one if you keep at it is the order least likely to be wasted. What to avoid is thinking “since I’m buying, let’s get a good one,” choosing a large model, and ending up with a piece of furniture that just sits there.

SituationWhat to prioritizeWhat to avoid
Apartment building, used at nightLow transmission to the floor, fine steps at the weak endModels that advertise high output or high speed
Shared by familyWeight capacity margin, handrail, resets to weakest when powered on againPassing a light, small unit around everyone
Used with storageSlimness, weight you can stand up with one hand, non-slip measuresOnes with an integrated post that cannot be taken apart
Low frequencyThe ease of using it seated, simple operationLarge models loaded with multi-function programs
💡

If you are unsure, first ask yourself whether you could leave the product out all the time. People who could leave their vibration machine out are the ones who keep using it. Conversely, if you choose the unit before deciding where it will go, the chance that you stop using it goes up regardless of its performance.

Before you use it: important health and safety notes

A vibration machine is a device that, more than other fitness equipment, cannot simply be called something anyone may use freely. Please be sure to read this part before buying and before use.

📝

A vibration machine is not a device that makes you lose weight or build muscle just by standing on it; it is a prompt and a support for exercise. Results vary from person to person, so do not expect too much. For your health, combine it with a balanced diet and moderate exercise. Start with weak vibration for a short time and avoid long or overly strong use (dizziness, discomfort, strain on the body). Stop immediately if you feel dizzy, nauseous, in pain or unwell during use. If you have high blood pressure, heart disease, a bone or joint condition, osteoporosis, blood clots, are pregnant, use a medical device inside the body (such as a pacemaker), are after surgery, are unwell, or are an older adult, always consult a doctor before use. With types you stand on, watch out for falls: use it with a handrail or in a stable place, in non-slip socks or bare feet as specified. Avoid using it on an empty or full stomach or after drinking alcohol. Do not let children use it alone. Do not exceed the weight capacity, and always follow the usage time, intended users and contraindications in the instruction manual. If you notice anything wrong with your body, stop using it and consult a medical institution.

How to use it so you can keep going without strain

It is said that rather than just standing on it, being aware of your body and moving it, such as taking a light squat posture, stepping in place, or changing where and which way you stand, makes it easier to use as a prompt for exercise (always within a comfortable range). Building it into daily life, such as while brushing your teeth or watching TV, makes it easier to continue, but it is not a substitute for strength training or aerobic exercise. Watch how your body feels and aim to make it a habit.

When and how to buy for the best deal

A vibration machine is a relatively expensive item, so the timing of purchase and how you stack point rewards change what you actually pay. Even so, rather than “aiming for the lowest price moment,” the order that gives higher satisfaction is to first identify the one that suits your body, then buy it at a good time.

  1. Settle the type and posture firstUp-down / side-to-side / 3D, standing, sitting or one body part. Once this is decided, you can narrow it to a few models.
  2. Narrow down actual models by quietness, weight capacity and safety featuresIn an apartment, assume quiet plus anti-vibration. A weight capacity with room over your weight, and whether there is a timer or handrail.
  3. Stack point rewards during sale periodsBig sales and the new-life season are good times for discounts plus rewards. Fitness equipment tends to show up at these times.
  4. Check reward rates and conditions on each official pageMall point multipliers and campaign conditions change, so check the latest on each official page before buying.
💡

Realistic targets by mall: For vibration machines, the number of reviews changes a lot how much you can learn about the real sound, shaking and ease of assembly. Reading what people say about the feel in a mall with plenty of reviews, and then buying during a sale period when the point multiplier goes up, is a way of buying that works especially well for this product. For larger models, also check the delivery and setup conditions (to the front door, or into the room). Prices, specs and rewards change with the season, so make the final decision on each official page.

The few times a year it is easier to move, and how to tell what comes before and after

Vibration machines are not a category that gets a model change every year like TVs or refrigerators. It is not unusual for the same model to stay on sale for years, but fitness equipment in general is characterized by clear seasons when demand moves. Thinking about these two traits separately makes the right time to buy easier to see.

When demand moves

Exercise equipment gets attention at the start of the year and in early spring. This is because people who want to build an exercise habit in the new year overlap with those thinking about the season of lighter clothing. In this period there are more products and more choices, but popular models tend to run low on stock. Conversely, midsummer and the busy end of the year see relatively less interest in indoor fitness equipment. “You can choose more calmly when it is not a hot topic” is the plain tendency in this category.

How to deal with big sales

The big sales at major malls come around each season. For a category like vibration machines, where differences in function are hard to see and people rarely buy a specific brand by name, exposure increases in a concentrated way during these sale periods. But note that what is put at the front during a sale is not necessarily a good model. It is natural that entry-level models with large room to discount, and older models the seller wants to clear, appear in prominent positions. If you find one in a sale, do not decide on the spot; apply the checks above (vibration type, actual size where you can place your feet, weight capacity margin). If it meets the conditions, it is a good time to buy; if not, it is just cheap.

How to tell whether it is a long seller

In this category, a model that has been on sale continuously for years is itself a piece of evidence. Durability of moving parts such as the motor and bearings matters in fitness equipment, so a product that has been sold for a long time without reports of major defects can be considered to have had a sound design. Looking at whether the product page mentions things like “series cumulative sales” or “Nth generation,” and whether review dates are spread over a long period, gives you a rough idea of how long that model has been on sale. Conversely, if reviews are clustered in a short period, it may be new. Being new is not bad in itself, but factor in that durability information has not yet accumulated.

Why there is no need to rush

A vibration machine is not like a seasonal appliance where you cannot use it this season unless you buy now. If anything, buying before you have settled where it goes and how you will use it (standing or sitting, at what time of day) makes it easy to get the type wrong. It is not too late to put a cardboard box of about the same size where you plan to set it up, and try it for a few days to see whether it gets in the way of your daily movement before deciding. The most expensive purchase in this category is buying a model that does not fit your conditions, cheaply.

💡

A bundle that comes as a “set” with a mat or cover is convenient in that you get what you need, but the thickness and material of the mat may not suit your floor. If the set contents are the selling point, first check whether the unit itself meets your conditions, and treat the accessories as things you can swap out later; that keeps a good balance.

What the unit alone does not cover / things that are recommended but can wait

A vibration machine can be used as soon as the unit arrives, but in apartment buildings or rooms with tatami or wood flooring, there are several things you realize in the first week that you cannot do without. Conversely, there are also things that tend to be recommended as a set but rarely get used.

Almost always needed

  • Anti-vibration, soundproof mat: This is the top priority. With a vibration machine, the bigger problem is not the motor noise itself but the low vibration that travels through the floor. You can also combine a thick exercise mat or anti-vibration rubber pads made for washing machines. If you put it directly on wood flooring, the unit can creep along little by little, so the mat also works as a non-slip layer.
  • Non-slip socks, or a clean plate surface you can stand on barefoot: Ordinary socks slip on the plate. With up-down types especially, it is dangerous if your feet slide, so socks with grips are reassuring. If you use it barefoot, sweat and skin oils make the plate slippery, so have a cloth ready for wiping.
  • Something to hold on to: If you use a model without a handrail standing up, check that there is stable support nearby. You need something that will not move even when it shakes, such as a wall or the edge of a sturdy desk. A chair with casters or a light shelf is dangerous as support.

Things that widen how you can use it

A thick bath towel or cushion comes in handy when you sit and rest your feet on it. Just laying one thin towel over the plate softens how the vibration hits and makes it easier to keep going. Also, when you use it seated on a chair, the chair height changes the angle of your knees and how the vibration reaches you. A cushion with adjustable height makes it easier to find the angle that suits you.

Another thing that works surprisingly well is a timer or a desk clock. Many models have an automatic stop, but the default time may not suit you. At first you want to keep sessions short and see how it goes, so having a clock in view, separate from the unit’s timer, helps prevent overuse.

Often recommended, but not high priority

  • Included exercise bands and ropes: These hook onto the front of the plate to move the upper body too, but not many people actually keep using them. They do no harm to have, but you almost never need to choose a model by whether it has them.
  • A wide variety of program modes: This is a function that switches strength automatically. It is novel, but the more someone uses it every day, the more they settle on a constant strength that suits them. Making the number of modes the deciding factor takes your eyes off the type and weight capacity you should really be looking at.
  • Calorie display: Since it does not actually measure your weight or exercise amount, it is safer not to give it more meaning than a rough guide. Whether it has this display is not a reason to choose.
  • A dedicated cover: Useful as dust protection, but putting a cover on makes taking it out a hassle and can backfire by lowering how often you use it. If you use it left out, wiping it down is a habit that lasts better than covering it.
💡

When you use it on tatami, the feet of the unit can dent the mat or damage the weave. Putting a rather firm board or mat under it so it is supported by a surface reduces damage to the tatami and the transmission of vibration at the same time. On carpet too, long pile makes the unit tilt and become unstable, so putting a flat board under it is safer.

💡

As for the order in which to add things, first the anti-vibration mat, then non-slip socks, and if you still feel something is lacking after using it that far, adjust the feel with a towel or cushion; that flow avoids waste. Adding as you go rather than buying a full set from the start leaves you with things that suit how you actually use it.

Common regrets with vibration machines

If you look at reviews and the voices of people who replaced theirs, the regret patterns are similar. All of them can be avoided if you know in advance.

  • Buying with too much faith in the effect → You do not lose weight just by standing on it. Understand it as a prompt and a support for moving your body, and combine it with diet and exercise.
  • Buying without checking how it shakes (type) → “It’s not the shaking I expected.” First learn how up-down / side-to-side / 3D feel different.
  • Choosing by the number of levels → You end up using only a few steps. Put weight on how gentle the weakest setting is and how comfortable the steps are.
  • Underrating quietness and anti-vibration in an apartment → It is heard downstairs and causes trouble. Take care with quiet design + anti-vibration mat + time of day.
  • Not checking weight capacity and size → Breakdown, or no room for it. Check a weight capacity with room over your weight, and space to set it up and store it.
  • Using it on your own judgment despite a medical condition → Strain and danger to the body. For high blood pressure, heart conditions, pregnancy, osteoporosis and the like, consult a doctor.
  • Strong and long from the start → Dizziness, discomfort. Get used to it with weak, short sessions.

Frequently asked questions

Up-down, side-to-side (swinging) or 3D: which should I choose?

Up-down vibration is fine, fast shaking for people who want to stand and shake the whole body. Side-to-side (oscillation) is a gentle motion that tilts like a seesaw. 3D combines several directions and is liked by people who tire of the same motion. The type does not decide the “effect,” so if you can try one, check how the weakest and strongest settings feel and choose the shaking that is comfortable enough for you to keep using.

Are more vibration levels better?

Not necessarily. Even with 99 levels, most people actually use only a few. More than the number of levels, how gently you can use the weakest setting and whether the steps feel comfortable to you directly affect how easy it is to keep going. Value gentleness at the low end and ease of adjustment over a big number.

I’m unsure about standing on it. Is a seated type okay?

Yes. If you are unsure about standing or worry about wobbling, do not force yourself into a whole-body type; a type you place on a chair or the floor and use seated, or a compact footrest type, is safer. You can apply vibration to your legs and hips while seated, and it also suits older adults and people unsure about exercise. Choose honestly according to your strength and sense of balance, and watch out for falls.

If I use it in an apartment, won’t it be heard downstairs?

Because of how it works, sound and vibration travel easily into the floor and carry. Choose a model with quiet design, always use an anti-vibration mat, and avoid late night and early morning. Standing whole-body types vibrate more strongly, so in an apartment building seated types, compact ones and those with high quietness are the safer choice. Checking reviews for the actual sound is the realistic approach.

How should I look at weight capacity?

For types you stand on, choose a weight capacity with room to spare over your body weight. Being right at the limit leaves concerns about breakdown and safety. Check the unit size as well, for where it will go both when in use and when stored. Slim models and ones with casters are easy to take out and put away, which helps you keep using them.

Can I use it if I have a medical condition?

If you have high blood pressure, heart disease, a bone or joint condition, osteoporosis, blood clots, are pregnant, use a medical device such as a pacemaker, are after surgery, are unwell, or are an older adult, vibration may affect your body, so always consult a doctor before use. Do not use it on your own judgment. If you feel anything wrong during use, such as dizziness, nausea or pain, stop immediately and consult a medical institution.

How long and how often should I use it?

Start with weak vibration for a short time and let your body get used to it. Long or overly strong use can cause dizziness, discomfort and strain on the body. Follow the guideline for usage time in the manual and do not overdo it. A timer is reassuring. Using it for long hours every day does not make it more effective; what matters is continuing without strain, according to how you feel.

Can I lose weight or build muscle just by standing on it?

No. A vibration machine is not a device that makes you lose weight or build muscle just by standing on it; it is a prompt and a support for moving your body. Results vary from person to person, so do not expect too much. For health and dieting, combining a balanced diet with moderate exercise is important. Use it without strain, purely as a prompt to make up for lack of exercise.

Can children or older adults use it?

Please avoid letting children use it alone (risk of falling or misuse). For older adults, standing carries a risk of wobbling and falling, so use a seated type or one with a handrail, starting carefully with low vibration. If you have weak bones or joints, osteoporosis or a medical condition, vibration can be a strain, so always consult a doctor before use. Regardless of age, follow the intended users, contraindications and usage time, and put safety first.

The unit moves little by little while I use it. Is it broken?

It is not broken; it is the unit sliding because of the vibration, which often happens on wood flooring or thin carpet. Lighter models tend to move more. Lay an anti-vibration mat with a non-slip function, and check that the rubber parts of the feet are free of dirt and dust. If it still moves, you may also be standing off the center.

Should I stand on it, or sit on a chair and rest only my feet on it?

If you choose by how easy it is to keep going, using it seated is less strenuous. When standing, your full weight is on the plate, so the stimulation and the transmission to the floor are bigger, and you also have to keep your balance. Starting seated for a short time and moving to standing if it feels like too little is the safer order. If you plan to stand, checking in advance whether there is a handrail helps you avoid having to choose again.
