ComfiLife Foot Rest Under Desk
Anyone whose feet do not sit flat on the floor with thighs level.

The most useful twenty-something dollars on this page. Once the chair is high enough for your elbows to meet the desk, your feet usually stop reaching the floor, and everything after that goes into the lower back. High-density foam that has not flattened in our use, with a washable cover and a base that stays put on carpet.
What's good
- Fixes the most common setup fault
- Foam holds its shape
- Washable cover
What's not
- Fixed height
- Takes floor space under a shallow desk
