Buying Guide
What We Wish We Knew Before Buying
The biggest mistake is buying a foot rest to fix a chair that is simply too high or too deep. With your feet supported, your knees should land roughly level with or a little below your hips, and your lower back should still meet the chair back comfortably. If your thighs feel jammed upward, the foot rest is too tall.
Placement matters just as much as height. Keep the foot rest close enough that your whole foot, especially the heel, stays supported without reaching forward with your toes. When it sits too far away, you end up tensing your shins and sliding away from the chair, which can make back pain worse instead of better.
It also helps to switch between still support and gentle movement during the day. Even a very good foot rest works best alongside a sensible setup with the monitor high enough, the keyboard close enough, and your shoulders able to stay relaxed.
Worth Knowing Before You Buy
This will not fix a chair that is too high or too deep, and that is where most people go wrong. If the foot rest pushes your knees above your hips or lifts your thighs, it is making your posture worse and can aggravate back pain. It also needs to sit close enough to support your whole foot, including your heel, or you will point your toes forward and keep your shins tense all day.

The ErgoFoam Adjustable Foot Rest Under Desk is the best pick for most people because it combines firm support, practical height adjustment, and gentle movement that helps prevent stiffness. If you work in shoes and want something easier to wipe clean, the Kensington SoleSaver Adjustable Footrest is the better fit.

Frequently Asked Questions ▾
Does a foot rest actually help back pain?
It can, especially when your back pain gets worse from desk posture. A foot rest supports the feet, helps level the hips, and can keep the lower back from rounding when your chair is a little too high. It is not a cure for every kind of back pain, but it often makes seated work much more tolerable.
What height should a foot rest be for desk work?
Your feet should sit fully supported with knees around a right angle or slightly more open, and your hips level with or a touch higher than your knees. If your thighs feel pushed up or your knees sit too high, the foot rest is too tall. If your feet still feel like they are reaching, it is too low.
Is foam or hard plastic better for back pain?
Foam usually feels better barefoot and spreads pressure more gently across the feet. Hard plastic or wood tends to feel more stable with shoes and is easier to clean. For back pain, the bigger factor is usually whether the height and firmness keep your pelvis and knees in a better position.
Where should a foot rest sit under the desk?
Keep it close enough that your whole foot, including the heel, rests naturally without reaching forward with your toes. When the foot rest is shoved too far out, you end up tensing your shins and sliding away from the chair back. That can cancel out the posture benefit.
Can a foot rest replace a better chair?
No. A foot rest helps fine-tune a setup, but it cannot fully make up for a seat that is too deep, poor lumbar support, or a monitor that forces you to hunch. If your chair is close to right but not quite there, a foot rest is often the missing piece.
