A footrest on an ergonomic chair supports your feet when the seat sits too high, easing pressure behind the thighs and helping you hold a neutral posture.
The chair arrives, the seat won’t go low enough, and your feet dangle an inch above the floor all afternoon. That gap is what a footrest closes. Whether the footrest built into a chair actually helps comes down to stability, size, and how you set the chair around it.
What A Footrest Actually Does For Your Posture
A footrest restores leg support that a too-tall seat takes away, which is its main job and the reason OSHA names it. When your feet hang, your thighs take the body’s weight across a narrow band of the seat edge, and that contact stress builds through the day. Raising the feet onto a stable surface spreads the load and lets the knees ride level with or slightly above the hips.
Ergonomic quality, though, doesn’t come from the footrest alone. OSHA describes a well-designed, properly adjusted chair as one that supports the back, legs, buttocks, and arms while cutting awkward postures and forceful exertion. Herman Miller lists adjustable arms, seat depth, and support for the head and legs among the features that matter. A footrest covers one of those needs; it can’t cover the rest.
- Real benefit: support when the seat can’t be lowered without pushing the keyboard or monitor too high.
- Not a substitute: lumbar support, seat depth, arm position, or monitor height.
- Only as good as its setup: a narrow or wobbly footrest can restrict movement and add knee or hip strain.
Setting Up The Chair And Footrest In The Right Order
Dial in the chair first and the footrest last, because each adjustment changes the ones above it.
- Set seat height so your feet rest fully on the floor or footrest with knees about level with, or slightly below, the hips.
- Set seat depth so your back meets the backrest while the seat edge stays clear of the backs of your knees.
- Adjust the backrest and lumbar support to hold your lower back without pushing your torso forward.
- Set armrests so your shoulders stay relaxed and your elbows rest near your body.
- Position the monitor and keyboard so you don’t bend your neck or reach, and check that the footrest didn’t push your desk surface too high.
- Treat a retractable footrest as support for reclining or short breaks unless the maker built it for all-day use.
- Redo the setup after you change shoes, desk height, chair height, or recline angle.
Each step can undo the last one. Raise the seat to fix your monitor and your feet may leave the floor again, which sends you back to the footrest height.
What To Check Before You Buy
Weight capacity printed on a listing usually covers the chair frame, not the footrest, so confirm both in the current manual before ordering. Retailer prices move constantly too, and the listings below came from marketplace data rather than manufacturer list prices.

These are starting points, not verdicts. Dimensions, desk clearance, caster fit, upholstery, and return policy all decide whether a chair works in your space. Our tested roundup of the best office chairs with footrests walks through which models held up under real setup conditions.
Mistakes That Undo The Benefit
Assuming a footrest makes a chair ergonomic is the first error. Fit, adjustability, and your setup do that work. A footrest that’s too narrow, unstable, or cranked too high can limit how you move and add strain at the knees and hips.
Reclining with the footrest extended while you type is another common one. It pulls your body away from the desk and pushes your neck and shoulders forward. Use that position for breaks, not for typing. And when your feet still dangle after every adjustment, the seat is simply too high for you.
OSHA’s guidance on workstation chair selection and adjustment covers the full set of adjustments, from seat depth to arm position.
When A Footrest Is Worth It
If your feet reach the floor once the chair is set correctly, you don’t need one. If they don’t, and lowering the seat wrecks your keyboard and monitor position, a stable footrest is the fix. Check the height range first, then the footrest’s stability and width, then everything else.
Common Questions
Does every ergonomic chair need a footrest?
No. It’s only needed when the seat can’t be lowered far enough to let your feet rest flat on the floor. Once the chair is adjusted for your keyboard and monitor, check where your feet land. If they’re supported, skip it. If they dangle, a stable footrest restores that support.
Should my knees be higher than my hips?
Slightly higher is fine and often helps. OSHA notes a footrest may raise the knees a bit to reduce pressure behind the thighs. The key is that your feet stay fully supported and your thighs don’t press hard into the seat edge. If your knees ride far above your hips, lower the footrest.
Can I use a footrest while typing?
Yes, with the chair upright or only slightly reclined so you stay close to the desk. With the footrest extended and the back pushed far down, your body drifts away from the keyboard and your neck and shoulders pitch forward. Save the deep recline for breaks instead of active typing.
