Feet Don't Touch the Floor? Fix Your Office Chair Fit

If your feet don't touch the floor in your office chair, check three things: seat height, desk height, and seat depth. The right adjustment gives your feet steady support while keeping your back supported and your keyboard within easy reach.

Unsupported feet can make an otherwise comfortable chair harder to use. The seat edge may press into your thighs, or you may slide forward to reach the floor and lose contact with the backrest. Holding that position through a long work session can add to fatigue. OSHA's chair guidance identifies both unsupported feet and excessive seat depth as workstation fit problems.

Your feet can rest on the floor or a suitable footrest. What matters is that the chair, work surface, and foot support fit together, with room to change position.

Find out what is keeping your feet off the floor

Sit back against the backrest in the shoes you normally wear at your desk. Then check which situation describes your setup.

Our office chair size guide explains how these measurements work together.

1. Lower the seat, then check your keyboard

Follow your chair's height-adjustment instructions and lower the seat in small increments. Keep your back comfortably against the backrest as you check the result.

Look for full foot contact, rather than just your toes touching. Your thighs should feel supported without firm pressure from the front edge of the cushion.

Now bring your hands to the keyboard. Can you type with relaxed shoulders, elbows close to your sides, and wrists straight? Mayo Clinic's office ergonomics guide recommends those upper-body checks alongside supported feet.

If your shoulders rise after lowering the chair, the desk or keyboard surface needs attention too. Getting your feet flat on the floor should not leave you reaching up throughout the workday.

2. Use a footrest when the desk needs a higher seat

A fixed desk can put your arms and legs at competing heights. The seat position that lets you type comfortably may leave a gap beneath your feet.

If the desk adjusts, lower the work surface to suit your seated position. At a fixed desk, a properly installed keyboard tray may help, provided it leaves enough room for your thighs. If the work surface cannot be lowered, OSHA recommends raising the chair and providing a footrest as needed.

Choose an under desk footrest with a stable base and enough surface for both feet. Set its height and angle so your soles rest comfortably, without lifting your knees into the underside of the desk. Leave space to reposition your feet.

For example, if a small increase in office chair height makes typing comfortable but lifts your heels, add support beneath your feet and reassess the whole position. Our guide to when a desk footrest is useful covers this setup in more detail.

3. Check seat depth before adding accessories

Height is the distance from the floor to the seat. Seat depth is the distance from the back of the seat toward your knees. A chair can be low enough and still feel too large.

Sit back and check the space behind your knees. The cushion should support most of your thighs without its front edge pressing into the backs of your knees.

If your chair has a seat-depth adjustment, shorten it and check again. If its depth is fixed, a shallower seat may be a better fit. A footrest can support your feet, but it does not shorten an oversized cushion.

Also check any added seat pad. Extra thickness raises your sitting position, which can explain why your feet stopped reaching after you added one. Reassess the height with the pad in place.

4. Choose a chair by the fit you can actually use

If you are considering a replacement, check the minimum seat height and seat depth before comparing extra features. Try the chair with your back supported, then confirm that you can reach the keyboard comfortably with your feet supported.

The LiberNovo Omni is offered in 45 cm and 48 cm fixed seat depths, approximately 17.7 and 18.9 inches. These are size choices, not a sliding seat-depth adjustment. Choose by your seated measurements and the space behind your knees.

Once the dimensions fit, consider how support responds when you move. LiberNovo's approach to Dynamic Ergonomics combines Dynamic Support with a Bionic FlexFit Backrest that adapts as you shift. Coordinated movement through the seat, backrest, armrests, and Neck Support helps support changes in position. Check the dimensions first so you can use that support comfortably.

5. Keep the support and make room to move

Supported feet give you a comfortable starting position. Small movements, a supported lean, and time away from the chair still belong in the day. OSHA advises changing position frequently, even at a well-arranged workstation.

Try the setup while typing, reading, and leaning back. Reposition the footrest if it becomes difficult to reach. Our working-from-home sitting guide covers the wider setup.

Check the whole fit before you settle in

Start with the adjustment that addresses your setup: a lower seat, a better-positioned keyboard, foot support, or a shallower cushion. Once those pieces work together, you can spend less of the day readjusting and more of it comfortably focused on your work.
