Varier Variable Balans Review: Who It Actually Fits

The verdict

Buy it if you want to rock, and if you have measured your desk first. The Variable Balans does one thing that no mechanical kneeling chair does as well: it is a sled you can move on continuously for hours, with no mechanism to wear out and no levers to set wrong. The seven-year warranty on the wood frame is a reasonable statement about how long a chair with no moving parts should last.

Do not buy it as the chair you sit in all day, and do not buy it expecting to adjust it to a desk you already own. Those are the same limitation stated two ways. BTOD publishes the seat as 18 inches high at the front and 20.5 at the back - a fixed, sloped pan, not an adjustment range - and there is no gas cylinder in the chair to change it. If your working surface does not suit a seat at that height, nothing about this chair bends to meet you.

What the rocking is actually for

A kneeling chair opens the angle between your thigh and your torso, which lets the pelvis sit upright without a backrest pushing it there. That is the argument for the whole category and it is set out properly in what a kneeling chair actually does.

The Variable Balans adds a second idea on top: the base is a curved sled rather than a fixed frame, so the chair moves under you the whole time you are on it. BTOD describes two rocking zones - a forward one for working at the desk and a rearward one nearer upright for pausing - and the practical effect is that you change position constantly instead of holding one. That is worth something specific. The problem described in what happens when you sit all day is not really a problem of bad posture, it is a problem of unchanging posture, and a chair that will not let you stay still is a direct answer to it.

It is also the reason this chair has survived while most kneeling chairs are interchangeable. The rocking does not depend on a mechanism, so there is nothing in it to loosen, sink or seize.

The published figures

Source: BTOD's published dimensions for the Variable Balans. Note what is absent as well as what is there. Varier does not publish a recommended user height for this chair, so we are not going to invent one - the usable check is the seat height against your desk, worked below. A backrest is sold as a separate accessory; it is not part of the chair reviewed here.

Fit, mapped to your body

Seat height is the gate and it is covered above. There is one wrinkle worth stating plainly: on a kneeling chair part of your weight goes through your shins, so the seat height is not doing the same job it does on a task chair. It still sets how high your torso ends up, which is what decides whether your forearms reach the desk level.

Seat depth is 12 inches, which would be absurd on an office chair and is normal here. You are not sitting back into this pan; you are perched forward on it with your shins taking the rest. Do not compare that figure to the one you calculate in the seat depth guide - that method assumes a conventional seated posture with a backrest behind you.

Seat width is 16 inches, the narrowest in our registry. If width across the hips is your constraint this is structurally the wrong shape, and chairs for wide hips is the page you want.

Weight capacity is 240 pounds, and this is the hardest limit on the chair. It is 60 pounds below the next-lowest rating on this site and 210 below the highest. A capacity rating is a structural number, not a comfort preference, so if you are near it, treat it as a no. Office chairs rated to 400 pounds is the other end of the same specification.

Where it is strong

• Nothing to fail. No gas lift, no tilt mechanism, no tension spring. The most common office chair failure on this site is a sinking gas cylinder - why chairs keep sinking - and this chair cannot have it.
• Continuous movement, by design. The sled base means you rock the whole time you are on it, in a forward working zone and a rearward resting one. No task chair offers that, and sitting still is the actual problem for most people reading this site.
• It weighs 11.5 pounds. Light enough to pick up with one hand, which is what makes a two-chair rotation practical rather than theoretical.
• A seven-year frame warranty on a chair with no mechanism. Five years on foam and fabric alongside it. Those are the parts that actually wear here.
• No shin-pressure shortcut. The 10.5 by 5.5 inch knee pad and the polyurethane foam are published, so you can see what is carrying your shins rather than guessing from a photograph.

Where it is weak

• Nothing adjusts. This is the defining limitation and it is not a flaw so much as a design position. A chair with no mechanism cannot have adjustment, and the two things you most want to set on a kneeling chair - seat height and the seat-to-knee angle - are both fixed here.
• 240 pounds. The lowest published capacity on this site, and a hard structural ceiling.
• No backrest unless you buy one. BTOD is direct about this: beyond two to three hours most people want the accessory backrest, and it is a separate purchase at a meaningful fraction of the chair's own price. Budget for it or plan on short sessions - how long you can actually sit in a kneeling chair is the honest version.
• No casters. A sled base does not roll, so you cannot push back from the desk or move sideways to a second monitor without standing up. BTOD lists low sitting mobility as a downside and it is a real one for a working day.
• Shin pressure is still shin pressure. Padding helps and does not remove it. If your knees are the reason a previous kneeling chair failed, read are kneeling chairs bad for your knees before spending premium money to find out again.
• It is priced in the premium tier. This is a wooden sled with foam on it, sold against chairs with ten adjustments and twelve-year warranties. The money buys durability and the rocking action, not features.

Who should not buy one

• Anyone whose desk does not suit an 18-inch seat. The most important line on this page, and the one that is not fixable later.
• Anyone over 240 pounds. Structural, not negotiable.
• Anyone who needs lumbar support. Sciatica, a herniated disc or stenosis all want adjustable support behind you, which this chair deliberately does not have. The sciatica roundup is the right page, and kneeling chairs for back pain is where the category's limits for pain are set out.
• Anyone with knee, shin or ankle problems. The mechanism that makes a kneeling chair work is pressure on the shins.
• Anyone buying one chair for eight hours a day. Rocking is excellent in stretches and tiring as a default. Kneeling chair versus office chair sets out the trade.

Alternatives worth reading

• Best kneeling chairs - the full category, including the adjustable ones that can be matched to your desk.
• Kneeling chair vs saddle chair - the same open-hip-angle argument without the shin pressure.
• HAG Capisco 8106 review - the saddle version of this idea, with adjustment and a perch rest.
• Best saddle stools - cheaper, and a different trade again.

This review is built on the published figures with the source linked, and it states what Varier does not publish rather than filling the gap. We did not sit in this chair and do not claim to have; our method is set out in full in how we pick.
