Ergonomic task chairs, by body and need

There is no best office chair. There is a chair whose published seat height, seat depth and lumbar travel fit you - and the figures that decide it change by page.

Three ergonomic task chairs of different sizes beside a desk

We do not have a best-office-chair page, and that is deliberate. The phrase assumes there is a chair that suits everyone, and there is not - a chair fits a body, and bodies differ by more than the adjustment range of most chairs.

So this hub is organized by the fit problem you have, and each page ranks on the figure that problem actually turns on. Those figures differ:

[For tall people](/chairs/for-tall-people) - the seat-height ceiling and, more importantly, the seat depth. A long femur needs a long seat pan, and seat depth is fixed on almost every chair under $300.
[For petite users](/chairs/for-petite-users) - the seat-height floor and again the depth, from the other end. At 5 ft 2 in you want a seat around 15.8 in; the lowest chair we found starts at 17.7.
[Big and tall](/chairs/big-and-tall) - rated capacity, the standard behind it, and published seat width. Of seven chairs we verified, one publishes its seat width.
[For back pain](/chairs/for-back-pain) - published lumbar adjustment travel. Not the presence of "lumbar support", which everything claims, but how far it moves.
[For sciatica](/chairs/for-sciatica) - seat depth, recline range and pressure distribution across the seat pan.
[Tall office chairs](/chairs/tall-office-chairs) - the height band above a task chair, ranked on back support rather than the foot ring.
[Mesh vs cushioned](/chairs/mesh-vs-cushioned) - what each material does to pressure, heat and seat height.

The two figures almost nobody publishes

Seat depth. It decides whether the front edge of the seat clears the back of your knee - the thing OSHA's chair guidance specifically tells you to avoid - and it is fixed on nearly every chair in this price range. Four of the nine chairs we verified publish it. If a listing gives you a seat height range and no depth, it has told you the adjustable dimension and withheld the permanent one.

Lumbar adjustment travel. Every chair claims lumbar support. A molded bump in a fixed position supports whoever happens to have their curve at that height; for everyone else it is pressure in the wrong place. Two chairs on this site publish a travel figure - the best gives 2 inches over eight levels. Why position is the whole variable.

Work out your numbers before you shop

Two measurements and a minute. Popliteal height - floor to the underside of your thigh behind the knee, seated with feet flat - is your seat height. Buttock-popliteal length minus 2 inches of clearance is your maximum seat depth. Our table computes both from your standing height, and measuring your own beats any average.

Then read the published figures rather than the marketing, and check your numbers fall inside them with an inch of margin at each end.

What decides price

Adjustment count, and warranty. Those two track price far more closely than materials do. The chairs at the top of this field publish five separate adjustment systems and five-year warranties; the ones at the bottom publish a capacity figure and a color.

Which is why we compute cost per warranty year - the live price divided by the published warranty term. It is arithmetic no competitor in the set we surveyed publishes, it needs no test lab, and it cannot be faked. The best figure on this site is about $40 per warranty year; the worst is about $190.

The fix that is not a chair

Worth saying on a page about buying chairs. If your feet do not reach the floor when your chair is set so your forearms are level with the desk, the problem is your desk, and [a footrest](/support/footrests) solves it for about thirty dollars.

A standard 29-inch desk is set for a 5 ft 10 in user. Anyone shorter is choosing between correct elbows and correct feet, and most people resolve it by lowering the chair - which trades a leg problem for a shoulder problem. Set the chair for the desk, then put your feet on something. It is the highest-leverage cheap purchase in this whole category and it works with the chair you already own.
