How to Choose the Right Ergonomic Chair

Your lower spine curves inward; a chair should fill that gap so your back muscles don't have to. Look for adjustable lumbar you can move up, down, and in — a fixed bump rarely lands where your spine needs it.

Feet flat on the floor, thighs parallel to the ground, and a two-to-three-finger gap behind your knees. A sliding seat pan matters as much as height — long and short legs need different depths.

Arms should rest so shoulders stay relaxed and elbows bend near 90°. The best armrests move four ways — height, width, depth, and pivot — so they support you while typing, not just at rest.

You shouldn't sit rigidly upright all day. A smooth recline with tunable tension lets you shift weight and open your hips, while a lock holds a working angle when you need it.

Mesh breathes and flexes to your shape; cushioned foam gives plusher support but traps heat. Either works — the question is how long you sit and how warm you run.

Optional, but valuable if you recline often or take calls. A good headrest adjusts in height and angle to cradle your neck when you lean back — not to prop your head forward.
