For a standard desk (typically about 28–30 inches high), a compact swivel office chair with armrests should ideally offer a seat height range of roughly 16–21 inches from the floor to the top of the seat. That span fits most adults and allows you to set up a neutral, comfortable posture without overextending your legs or shrugging your shoulders.
At typical desk height, the goal is to sit with feet flat on the floor, knees near a 90-degree angle, and thighs roughly parallel to the floor. A seat that can drop to around 16–17 inches helps shorter users achieve solid foot contact, while a top end around 20–21 inches supports taller users so their knees don’t end up too high.
Start by adjusting the seat so your elbows fall naturally at desk height when your shoulders are relaxed. Then confirm your knees are comfortably bent and your feet stay planted. If you find yourself reaching up to type, the seat is too low; if your feet dangle or pressure builds under your thighs, the seat is too high (or you may need a footrest).
On a compact chair, armrests are great for brief support, but they can also prevent the chair from sliding in close. Look for armrests that sit low enough to clear the underside of the desk or that adjust downward. A good sign is when the chair can tuck in so you can sit close enough to type without leaning forward.
Manufacturers list seat height, but what matters is the range you can comfortably use with your desk and body. If your setup is tight, choose a chair that hits your target height while still letting you scoot in, swivel freely, and keep your arms neutral.

Yes—if you can’t lower the seat enough to keep your feet flat while maintaining good desk-level elbow position, a footrest helps support your legs and reduces pressure under your thighs.
