Your shoulders are up around your ears by lunchtime, your wrists bend upward to reach the keyboard, and the desk is a fixed slab of wood that is not going anywhere.
Picked on published fit specifications, not on hands-on testing. How we pick.
The short answer
Raise the chair until your forearms are level with the desk surface, then put something solid under your feet to replace the floor you just left. That order matters: the desk sets your arm height, the footrest restores your leg support. Lowering the desk is better, but a chair plus a footrest solves it for nothing.

The arithmetic, in two lines
A conventional office or dining desk is built at 29 to 30 inches from the floor to the work surface. That figure comes from an era of typewriters and standardized office furniture, and it is designed around a sitter of roughly 6 feet.
The height you actually want is the one that puts your forearms roughly level with the work surface, elbows at about 90 degrees, shoulders relaxed down. For most adults that lands between 24 and 27 inches. If you are 5 ft 6 in, the standard desk is about four inches too tall. That is not a small discrepancy - it is the difference between resting your arms and holding them up for eight hours.

Those are working figures derived from the same seated-elbow-height logic as our seat height lookup table, which shows the arithmetic in full and cites the anthropometric source it rests on. Use them to understand the size of your gap, then measure your own elbow height sitting properly - your proportions are yours, not a table's.
The three fixes, in order of how well they work
1. Lower the desk, if it can be lowered
Always the best answer, and more often possible than people assume. Many desks have adjustable feet or legs that unbolt; a lot of flat-pack desks can be shortened by cutting the legs, and a height-adjustable frame is cheaper than a premium chair. If the desk can come down to 25 or 26 inches, everything downstream of this gets easier and you need neither a tall chair nor a footrest.
2. Raise the chair and support your feet
The standard fix, and it works, but only if you do both halves. Raise the seat until your forearms are level with the desk. Your feet will now be off the floor or barely touching - and legs that hang pull your pelvis backward, flatten the lumbar curve and compress the underside of your thighs, which is the single most common unaddressed cause of desk back pain. So you then put something solid under your feet to replace the floor you left.
A footrest, a ream of paper, a sturdy box, a stack of books: the material does not matter, the solidity does. Our footrest page covers what to look for if you buy one rather than improvise.
3. Raise the keyboard instead of yourself
The one people forget. If the desk is too high, an under-desk keyboard tray brings the keyboard down to where your hands want it without moving you at all. This is the right fix when you are at the short end of the range and raising the chair four inches would put you uncomfortably high relative to the room, the monitor and the floor.
What a too-high desk actually does to you
Shoulders held up. Reaching up to the keyboard means the muscles across the top of your shoulders carry your arms all day. That load is felt in the neck and between the shoulder blades, not in the arms - best office chairs for upper back pain treats the symptom and this page treats the cause.
Wrists extended upward. A keyboard above forearm level bends the wrist back, which is the posture most associated with wrist and forearm complaints at a desk.
Feet unsupported, if you raised the chair. Half the fix without the other half trades a shoulder problem for a lower back problem.
Perching forward. People unconsciously slide to the front of the seat to get closer to a high surface, losing the backrest entirely.
Less common and easier. Raise the desk on solid blocks, bed risers or furniture risers under each leg - a desk is stable at height in a way a chair is not. Do not try to solve a low desk by lowering the chair past the point where your thighs sit level, because a seat that is too low tips your pelvis in the opposite direction and loads the sit bones instead.
And if the real issue is that no chair in the shop reaches the height you need, best office chairs for tall people lists the chairs whose makers publish seat heights above 21 inches, while best office chairs for short people covers the opposite end - where a tall desk is most often the hidden problem behind back pain that no chair seems to fix.
The picks in full
1. Best for A seat that reaches 21.5 inches and still drops to 16.5
Steelcase Series 1
If you have to raise the chair to meet the desk, you want a chair with room at the top of its range - and the Series 1 has the widest published travel of any chair in our registry at five full inches, from 16.5 to 21.5 inches. That matters in both directions: enough height to meet a 30-inch desk, and enough drop that the chair is still usable if you later lower the desk or move it. Steelcase also publishes a functional seat depth of 15.5 to 17.75 inches, a 400-pound rating and a 12-year multi-shift warranty. Adjustable lumbar is a configured option rather than standard.
Who it fits
Anyone stuck with a fixed desk who needs height at the top of the range without giving up the bottom.
Who it does not fit
Anyone under about 5 ft 2 in without a footrest, and anyone wanting lumbar included as standard.

The only chair in our registry whose published seat height starts above 18 inches and reaches 22, and the only one whose maker states a fit range openly in both directions: Autonomous puts it at 5 ft 4 in to 6 ft 6 in. For a tall sitter at a tall desk this is the pick that gets your forearms level without a stack of blocks under the casters. It publishes a 300-pound rating, adjustable lumbar and a lifetime warranty per Autonomous. The flip side is published just as plainly: this chair does not go low, so if you are short it is the wrong purchase no matter how high your desk is.
Who it fits
Taller sitters at a fixed desk of 30 inches or more.
Who it does not fit
Anyone under 5 ft 4 in - Autonomous itself says so - and anyone over 300 lb.
3. Best for Raising the back support as you raise the seat
Sihoo Doro C300
Here for a reason specific to this problem. When you raise a chair to meet a tall desk, the backrest goes up with it - and if the backrest is fixed, its upper edge can end up above where it should sit on your back while the lumbar bump lands too low. Sihoo publishes a backrest that moves through 18.11 to 21.65 inches of height independently, so you can put the seat where the desk needs it and the support where your back needs it. Also published: an 18.11-inch pan with depth adjustment, a self-adapting dynamic lumbar, a 330-pound rating and a three-year warranty. Sihoo publishes overall height of 42 to 49 inches and no seat height, which is a genuine limitation on a page about seat height.
Who it fits
Anyone whose back support ends up in the wrong place once the seat is raised.
Who it does not fit
Anyone who needs a confirmed seat height figure before ordering, and anyone over 330 lb.
Raise your chair until your forearms are level with the desk surface, then put something solid under your feet to replace the floor. Both halves are necessary: the first fixes your shoulders and wrists, the second stops your legs hanging and your pelvis tipping backward. If the desk can be lowered instead, do that - it is the better fix.
How tall should a desk be?+
Tall enough that your forearms are roughly level with the work surface with your elbows at about 90 degrees and your shoulders relaxed. For most adults that is 24 to 27 inches, against a standard desk height of 29 to 30 inches - which is why so many people are working four inches too high without realizing it.
Can a chair fix a desk that is too high?+
Partly. A chair with enough travel at the top of its range gets your arms right - the Steelcase Series 1 publishes 16.5 to 21.5 inches, the Autonomous ErgoChair Pro 18.5 to 22 inches. What a chair cannot do is support the feet you just lifted off the floor, so plan on a footrest as part of the same fix.
Is a footrest really necessary?+
If you raised the chair to meet a high desk, yes. Unsupported legs hang off the front of the seat, compressing the underside of the thighs and rotating the pelvis backward, which flattens the lumbar curve. That is the mechanism behind a large share of desk-related lower back ache, and a solid box under your feet removes it for nothing.
Would a standing desk solve this?+
It solves the fixed-height problem, because you set the surface where you want it in both sitting and standing modes. It does not solve sitting itself, and standing all day introduces its own problems - standing desk versus office chair sets out what each actually fixes.
