Some people sit down at nine and get up at five. Most of the customers who ring us about this do not. They shift every few minutes, sit sideways through a phone call, perch on the front edge of the seat when they are concentrating, cross a leg under themselves, get up, come back, and end the day having never once sat the way the chair diagram suggests.
If that is you, the useful question is not which chair is "most ergonomic". It is which chair lets you keep doing what you already do without fighting you. That question has measurable answers, and they are different for different kinds of restlessness.
This is a guide to the chairs we stock, sorted by the movement they actually accommodate. Every figure below comes from the manufacturer's own factsheet or, for our own-brand Kyoto, from our published specification. Where a manufacturer publishes nothing, we say so rather than filling the gap.
Perching is a posture most chairs cannot reach. Only one gas lift in our range gets a seat to 810 mm.
Four different kinds of "cannot sit still"
People use the same phrase for four quite different habits, and they point at different chairs.
- You change posture completely. Forward, sideways, astride, backwards, perched. You are not adjusting a chair, you are relocating on it.
- You rock. You stay facing the desk but you are constantly tipping the backrest, leaning in, leaning out, never locked.
- You change depth. You slide forward to the front third of the seat to concentrate, then back against the backrest to read, and you pull a foot up under you.
- You get up. Every twenty minutes, on and off, all day. The chair matters less than how quickly it gets out of your way and how easily it returns to where you left it.
Four habits, four different specifications. Here is what each one is asking the chair for.
The four numbers that decide it
Ignore the marketing vocabulary. For a restless sitter, four published measurements do nearly all the work.
Seat height range. Not the number itself, but the spread. A chair that runs 470 to 560 mm gives you 90 mm of movement. A chair that runs 550 to 810 mm gives you 260 mm and takes you from sitting to perching at a raised desk. This is the single biggest difference between the chairs below.
Adjustable seat depth. Whether the seat pad slides independently of the backrest. If you move between the front edge and the back of the seat all day, a chair with a fixed pad depth is making you choose once rather than letting you keep changing.
Tilt range. How far the backrest travels, and whether it tips forward of vertical as well as back. Forward tilt is what a leaner wants; rearward travel is what a rocker wants. They are not the same figure.
Where your feet go. The moment a seat goes above roughly 600 mm, your feet leave the floor and the chair needs a ring or a step, or you will stop using the height you paid for.
Note one thing we cannot give you: Flokk publishes no maximum user weight for any HÅG chair. The 110 kg figure that circulates is a condition of the ten-year guarantee rather than a tested load rating, and those are different measurements. Our guide to office chair weight ratings explains who certifies what. If you need a certified figure in writing, ask us and we will request the documentation.
If you change posture completely: HÅG Capisco
The Capisco has no single correct orientation. Astride, sideways and backwards are all intended positions, not misuse.
The Capisco was drawn by Peter Opsvik in 1984 around the posture of a rider on horseback, and it is built at Flokk's factory in Røros, Norway. The saddle-shaped seat and the open, T-shaped backrest are why it accommodates positions a conventional chair cannot: astride the saddle, turned sideways, or turned fully around with your chest or forearms against the backrest.
The numbers, from Flokk's 2025 Capisco factsheet, for the 8106:
| Gas lift | Seat height | What it reaches |
|---|---|---|
| 150 mm | 400–540 mm | A fixed-height desk |
| 200 mm | 460–640 mm | The usual choice |
| 265 mm | 550–810 mm | Perching at a raised desk or bench |
Seat heights are measured under a 64 kg load, so an unloaded chair sits slightly higher. The 8106 also has an adjustable seat depth of 370–470 mm, a 500 mm wide seat pad, a backrest adjustable through 440–500 mm, and a published chair weight of 12.1 kg.
The gas lifts are three separate cylinders, not three settings on one chair. Changing your mind later means buying a new cylinder — a quick job, but a purchase. Our Capisco gas lift guide works that decision through, and the measurements page holds every published figure for every model.
The Capisco Puls 8010 from $1,108.80 is the moulded-shell version: a 460 mm seat, a fixed 400 mm backrest, seat depth 400–470 mm, and the only model in the family carrying a cleanroom rating. The Puls 8020 from $1,108.80 is the same chair with an upholstered seat pad, which sits it roughly 10 mm higher at every lift. The 8106 versus Puls comparison puts the two side by side.
It suits you if you perch, sit astride, turn around, or work at a height-adjustable desk and want something between sitting and standing.
It does not suit you if you want to settle into one supported position for hours. It asks you to engage rather than sink, and it takes most people about a fortnight to stop noticing it. If that description makes you uneasy, the SoFi below is the chair we would put you in instead.

If you rock and lean: HÅG SoFi Mesh
The SoFi tips further forward than anything else we stock, which is what a leaner actually wants.
The SoFi is the conventional-looking chair on this page, and for one particular kind of restlessness it is the best answer in our range. Flokk's wording for the tilt, identical across its 2019 and 2025 factsheets, is: "Tilt range is 20° forwards and 14° backwards from a neutral position 4° to the rear." Twenty degrees of forward travel is a lot. If you spend your day leaning into a screen or a drawing, that is the movement you are asking for.
From the 2025 SoFi Collection factsheet, for the 7500 mesh model: seat height 390–540 mm on the 165 mm gas lift and 450–640 mm on the 200 mm; adjustable seat depth 380–460 mm; seat pad 440 mm deep by 450 mm wide; backrest 470 mm wide; backrest inclination 30°; chair weight 16.7 kg. It is certified EN 1335 Class A, the higher adjustability tier. Only the backrest is mesh — the seat is upholstered.
The 390 mm minimum seat height is the lowest of anything we stock, which matters more than it sounds: a restless sitter who is also short spends the day with dangling feet unless the chair goes low enough. That is the subject of our fit guide for shorter sitters.
One honest gap: which gas lift ships on our stocked SoFi is not recorded on the product page, and the two lifts give different ranges. Ring us before you order if the exact seat height decides it, and we will check the chair in the rack.
It suits you if you rock, lean forward into work, and want firm lumbar contact to push against while you do it.
It does not suit you if you want to perch. The SoFi tops out at 640 mm and there is no 265 mm lift for it, so it is not a standing-desk chair. For that, go back to the Capisco.

If you get up constantly: HÅG Tion
A 12 kg chair that rolls out of the way easily is worth more to a frequent stander than another adjustment lever.
If your restlessness is mostly vertical — up for a call, up for the printer, up because sitting has run out — then the qualities that matter are light weight, a low-friction base and not much to reset when you sit back down. The Tion 2340 Mesh weighs a published 12.0 kg, which is 4.7 kg less than the SoFi.
From Flokk's 2025 Tion factsheet: seat height 410–540 mm on the 150 mm lift and 480–660 mm on the 200 mm. For the 2340 Mesh specifically, the seat pad is 440 mm deep by 470 mm wide, the backrest 460 mm wide, backrest inclination 17°, neutral position −3°. The range is made with 54–75% recycled materials.
Now the limitation, because it is the important one on this page: no Tion model has adjustable seat depth. The row in Flokk's factsheet is empty. That is also why the Tion is certified EN 1335-1 (2020) Type B while the SoFi is Class A — a lower adjustability tier, honestly declared. If your restlessness is the sliding-forward-and-back kind, this is the wrong chair and the SoFi is the right one at a similar price.
It suits you if you are in and out of the chair all day and want something light, clean and quick.
It does not suit you if you need to change seat depth, or you need to perch.

If you are buying for a team: Kyoto
The Kyoto publishes a tested user weight against a named standard, which most chairs at this price do not.
When the restless sitter is one of thirty people and you cannot interview each of them, the honest answer is a chair with wide adjustment and a published load rating. The Kyoto is our own brand, so we publish its specification directly: seat height 470–560 mm, a seat depth slider covering 490–540 mm, a 500 mm seat, a 560 by 480 mm back, 4D armrests adjusting between 435 and 480 mm apart, a height-adjustable flexing lumbar support and a synchronised recline mechanism.
It is rated to 140 kg, tested to ANSI/BIFMA X5.1-2017 — a tested figure against a named standard, which is genuinely unusual under $1,000. Chair Dinkum is the warrantor on the Kyoto; the terms are on the product page and our warranty page, alongside the Australian Consumer Law rights that sit on top of them.
It suits you if you are specifying for a floor of people with unknown habits and need adjustment range, a load rating and a price that scales.
It does not suit you if you are short. The Kyoto's minimum seat height of 470 mm is 80 mm above the SoFi's, and for a restless sitter who is also below about 165 cm that is the difference between feet planted and feet dangling.
Kyoto Ergonomic Task Chair, 74 in stock, $599. Our guide to chairs under $1,000 compares it against the Tion and the SoFi on price.

The tilt figures in that row are the ranges printed in Flokk's 2025 factsheet tables, measured from level. Flokk also describes the SoFi's travel in prose as 20° forwards and 14° backwards from a neutral position 4° to the rear — two conventions for the same chair, both Flokk's own.

Wherever your feet end up
Raise a seat past about 600 mm and your feet leave the floor. If they have nowhere to go, most people quietly stop using the top half of the range.
The HÅG Capisco FootRing at $210.60 is 450 mm across and fits the 200 mm and 265 mm gas lifts only. There is no adapter for the 150 mm lift. It is colour-matched to the cylinder, so specify the two together. Flokk publishes no height-above-floor figure for it, and the spacer increments quoted on some reseller sites are not Flokk's, so we do not repeat them.
The HÅG StepUp at $297.90 clamps to the gas lift column and gives two foot levels. Flokk specifies it for 150, 200 and 265 mm lifts and for desk heights of 800–950 mm, which makes it the only foot support that fits a 150 mm lift. Flokk publishes no dimensions, weight or load rating for it, so we quote none.
The desk is half the problem
A chair that moves under a desk that does not is only half a solution. If you perch, the desk has to come up with you, and if you shift between four postures a day your screen has to follow — a fixed monitor on a fixed stand will drag you back to one position no matter what the chair allows. Our guide to choosing a monitor arm covers that side, and the standing desk setup guide covers the height arithmetic.
If the interest is specifically in why changing position is worth designing around at all, the science of active sitting takes that on. And if you arrived here because of ADHD in particular, we wrote about that separately and carefully in the Capisco and ADHD — including what the research does and does not support.
Our take
There is no best chair for people who cannot sit still, because "cannot sit still" describes at least four different habits that want four different things. What there is, is a short set of published measurements that will tell you which of our chairs matches yours.
If you perch or turn around, it is the Capisco, and the gas lift matters more than the model. If you rock and lean, it is the SoFi, and the 20° of forward tilt is the reason. If you are up and down all day, it is the Tion, as long as you do not need seat depth adjustment. If you are buying for a room full of people, it is the Kyoto, unless they are short.
None of these chairs will make you sit still, and none of them is meant to. Come and sit in them before you decide — all four are on the floor at our Pyrmont showroom, 1/209 Harris Street, Monday to Friday by appointment. Call 02 9640 0642 or get in touch, and tell us your desk height when you book so we can have the right gas lift under the chair. You can also browse the full HÅG range or every ergonomic task chair we stock.
Frequently asked questions
Which office chair is best if I cannot sit still?
It depends which habit you mean. If you change posture completely — astride, sideways, backwards, perched — the HÅG Capisco is the only chair in our range designed for it. If you rock and lean forward, the HÅG SoFi Mesh tips 20 degrees forwards, further than anything else we stock. If you are up and down all day, the HÅG Tion is light at 12.0 kg and quick to get back into. If you are buying for a team of people whose habits you do not know, the Kyoto has the widest adjustment at the lowest price.
Which chair can I perch on at a standing desk?
Only the HÅG Capisco, and only with the 265 mm gas lift, which gives a seat height of 550 to 810 mm. The 200 mm lift reaches 640 mm and the 150 mm lift reaches 540 mm. Nothing else in our range goes near 810 mm, and the SoFi and Tion have no lift option that gets there.
Does the HÅG Tion have adjustable seat depth?
No. No Tion model has adjustable seat depth — the row in Flokk's 2025 factsheet is empty. That is part of why the Tion is certified EN 1335-1 (2020) Type B while the SoFi is Class A. If you slide forward and back on the seat all day, the SoFi is the better chair at a similar price.
What is the lowest seat height you stock?
The HÅG SoFi Mesh at 390 mm on the 165 mm gas lift. The Capisco 8106 starts at 400 mm on its 150 mm lift, the Tion at 410 mm, and the Kyoto at 470 mm. Seat heights on the Flokk chairs are measured under a 64 kg load, so an unloaded chair sits slightly higher.
Do I need a footring?
If you raise the seat past about 600 mm, yes, otherwise your feet dangle and most people stop using the height. The HÅG Capisco FootRing fits the 200 mm and 265 mm gas lifts only and is colour-matched to the cylinder, so specify them together. On a 150 mm lift the chair-mounted HÅG StepUp is the alternative, and it is the only foot support that fits that cylinder.
What is the maximum user weight on a HÅG chair?
Flokk publishes none, for the Capisco, the SoFi or the Tion. The 110 kg figure that circulates for HÅG chairs is a condition of the ten-year guarantee rather than a tested load rating, and the two are different measurements. The Kyoto is the chair on this page with a tested figure: 140 kg, to ANSI/BIFMA X5.1-2017. If you need a certified figure for a HÅG chair in writing, ask us and we will request the documentation from Flokk.
How long does it take to get used to a saddle chair?
About a fortnight. The Capisco asks you to engage rather than settle, so the first few days feel unusual to nearly everyone. If you are trialling one, plan for that adjustment period before forming a view.
I concentrate better when I feel still. Is a moving chair wrong for me?
Not wrong, just not for you, and we would rather say so. If you work best feeling settled and supported, a conventional chair with firm lumbar contact suits you better — the HÅG SoFi Mesh at $750 is the one we would put you in, and it has the lowest minimum seat height of anything we stock at 390 mm plus adjustable seat depth of 380 to 460 mm.
