Adjust the chair first, then add a footrest if your feet do not rest comfortably while your arms still need the chair raised to match the desk height.
Key Takeaways
- Chair height should support both arm position and foot contact.
- A footrest is useful when the desk is too high to lower the chair enough.
- Foot support can reduce dangling-leg discomfort.
- A footrest does not fix a desk that is too deep or a monitor that is too low.

What to Check
Start with the chair
Raise or lower the chair until your keyboard and mouse feel reachable with relaxed shoulders. Then check whether your feet still feel supported.
If your feet dangle after the arm position feels right, a footrest can fill the gap without forcing the desk or keyboard height to change.
Use a footrest correctly
A footrest should support natural position changes, not lock your feet into one angle. Adjustable tilt can make it easier to shift during the day.
If you use a standing desk, you may need a different solution: better height presets, a mat, or a low foot rail for posture changes.
Comparison Table
| Situation | First fix | Possible add-on |
|---|---|---|
| Feet dangle | Lower chair if arms still fit | Footrest if desk is too high |
| Shoulders raised | Lower typing height | Keyboard tray or adjustable desk |
| Back unsupported | Adjust chair depth and lumbar | Small cushion if needed |
| Legs feel static | Change posture often | Rocking footrest |

Frequently Asked Questions
Do I need a footrest at my desk?
You may need a footrest if your chair must be raised for keyboard comfort but your feet no longer rest flat on the floor.
Can a footrest improve posture?
A footrest can improve support and comfort, but it should be part of a full setup that includes chair height, desk height, and monitor position.
Should I adjust my chair or buy a footrest first?
Adjust the chair first. Buy a footrest only if the best chair height for typing leaves your feet unsupported.
Bottom Line
Use this guide as a practical baseline, then adjust the layout to your room, body, workflow, and equipment. A good desk setup should be easy to work at and easy to reset.
