Fixing chair and desk height before buying anything

A better chair helps only after the desk is at the right height. Most discomfort comes from a mismatch between the two, which no chair can fix on its own.

Quick answer

Sit with feet flat and adjust the chair until the thighs are level.
Measure from the floor to your elbow and compare it with the desk height.
Raise the desk or the chair.

Why this keeps happening

Posture problems are usually geometry problems. If the desk is too high, the shoulders rise; if it is too low, the wrists bend. Both produce pain that gets blamed on the chair.

The second factor is time. Discomfort accumulates over weeks, so a change made today is judged today and discarded before it has a chance to work.

What to do, in order

Sit with feet flat and adjust the chair until the thighs are level.
Measure from the floor to your elbow and compare it with the desk height.
Raise the desk or the chair, whichever is adjustable, so the elbows sit near ninety degrees.
Add a footrest if raising the chair leaves the feet dangling; that is the common gap.
Move the monitor so its top edge is near eye level and about an arm's length away.
Keep the new arrangement for two weeks before judging it.

How to measure it

Pain-free hours per session is the measure. Track it weekly rather than daily, because the change is slow and daily noise hides it.

Mistakes that undo the work

Buying an expensive chair before fixing desk height.
Judging a new setup after one session.
Ignoring wrist angle, which causes more problems than back angle for mouse users.

Frequently asked

Do gaming chairs help?

Not inherently. An office chair with adjustable height and lumbar support is usually better value.

Is a standing desk better?

Alternating between sitting and standing is better than either alone. A desk that only goes up is a costume.

How long before posture changes feel normal?

Two to three weeks. The first days usually feel worse.
