A footrest is one of the most underrated ergonomic accessories. If your feet don’t rest flat on the floor when your chair is at the correct height, your legs dangle — creating pressure on the backs of your thighs, reducing circulation, and forcing your lower back to compensate for the lack of lower body support. This is especially common for shorter users (under 5’6″) and anyone using a chair that doesn’t adjust low enough. A footrest fills the gap between your feet and the floor, completing the ergonomic chain from your spine to the ground.
I prescribe footrests more often than any other ergonomic accessory. They’re cheap, they require zero installation, and they provide immediate relief for lower back pain and leg discomfort caused by improper seating height. Here are the best options for every budget and use case.
Humanscale FM300 Foot Machine<br />
Our Top Picks
1. Humanscale FM300 Foot Machine — Best Overall
The Humanscale FM300 isn’t just a platform for your feet — it’s an active footrest that encourages continuous leg movement. The rocking platform tilts forward and backward with your natural foot movements, engaging your calf muscles and promoting circulation. This active design prevents the static leg positioning that contributes to lower back pain and leg fatigue during long sitting sessions.
The FM300 adjusts from approximately 3.5″ to 5″ in height, with a tilt range of 0° to 20°. The platform is 18″ wide — enough for both feet with room to shift position. The non-slip surface keeps your feet in place, and the weighted base prevents the footrest from sliding on hard floors. Build quality is commercial-grade, with a steel mechanism designed for years of daily use.
At $100-$150, the FM300 is the most expensive footrest in this roundup. But Humanscale’s ergonomic expertise is evident in the design — the rocking motion is calibrated to encourage movement without being distracting, and the height/tilt adjustability ensures proper positioning for different chair heights and user sizes.
2. ErgoFoam Adjustable Foot Rest — Best Foam Footrest
The ErgoFoam is the most popular foam footrest on Amazon, and the appeal is straightforward: it’s a dense, comfortable foam platform that supports your feet at the correct height. The footrest has two height positions — flat (approximately 3.5″) or tilted (approximately 5.5″) — achieved by flipping the footrest over. The velvet-soft mesh cover is breathable and removable for washing.
The high-density foam provides firm support without bottoming out under foot pressure. The non-slip rubber base keeps the footrest in place on hard floors. The footrest measures approximately 17″ x 13″ x 5.5″ — compact enough to fit under most desks without interfering with chair movement. At $25-$35, it’s an affordable ergonomic upgrade.
The main limitation is the lack of continuous height adjustment — you get two positions (flat or tilted), and if neither is exactly right for your setup, you’re stuck. The foam will also compress slightly over time with daily use, though the high-density construction resists this better than cheaper foam alternatives.
3. Fellowes Professional Series Adjustable Footrest — Best Adjustable
The Fellowes Professional Series footrest offers the most precise height adjustment in this roundup. The platform adjusts from 3.5″ to 5.5″ in height with a smooth mechanism that locks at any position within the range. The tilt angle adjusts independently from 0° to 20°. This dual adjustability lets you dial in the exact height and angle that positions your feet correctly for your specific chair height and leg length.
The platform measures 19.5″ x 14.5″ — the largest in this roundup — providing ample room for both feet with space to shift position. The textured surface provides grip without being uncomfortable, and the non-slip base keeps the footrest stable. The platform supports up to 250 lbs of downward force. Build quality is solid — the Fellowes Professional Series is designed for commercial office environments.
At $40-$60, the Fellowes offers the best combination of adjustability and value. The continuous height and tilt adjustment is a significant advantage over foam footrests with fixed positions. For users who need precise ergonomic positioning, the Fellowes is the most practical choice.
4. HUANUO Adjustable Footrest with Massage Surface — Best for Circulation
The HUANUO footrest combines height adjustability with a textured massage surface that stimulates foot pressure points while you sit. The platform adjusts from approximately 3″ to 5″ in height with a tilt range of 0° to 30° — the widest tilt range in this roundup. The massage texture is subtle enough to be comfortable through socks but pronounced enough to provide genuine stimulation.
The footrest measures 16.5″ x 11.5″ — more compact than the Fellowes, which makes it better for tight under-desk spaces but less roomy for shifting foot positions. The non-slip base is effective on hard floors. At $25-$40, it’s affordably priced with features that compete with more expensive options.
5. ComfiLife Foot Rest — Best Memory Foam
The ComfiLife uses memory foam that conforms to the shape of your feet, providing personalized cushioning that distributes pressure evenly. The footrest has a single height of approximately 4″ with a gentle slope. The non-slip bottom keeps it in place, and the removable cover is machine washable. At $20-$30, it’s one of the most affordable ergonomic footrests available.
Memory foam provides a different experience than high-density foam — it’s softer and more conforming, which some users find more comfortable for extended sitting. The trade-off is that memory foam retains heat more than other materials, which can make your feet warm during long sessions. The foam also compresses more over time than high-density alternatives.
Who Needs a Footrest?
A footrest is beneficial if:
- Your feet don’t rest flat on the floor when your chair is at the correct height (elbows at 90° when typing)
- You’re shorter than 5’6″ and use a standard-height desk (28-30″)
- You experience lower back pain, leg numbness, or thigh pressure while sitting
- Your chair doesn’t adjust low enough for your height
- You want to encourage active leg movement during sitting
The test is simple: sit in your chair with your elbows at 90° and your back supported. If your feet don’t rest flat on the floor with your thighs parallel to the ground, you need a footrest. The footrest height should fill the gap between your feet and the floor.
Footrest Height Guide
- 1-2″ gap: Use a thin foam footrest or folded towel
- 2-4″ gap: Standard footrest (most options in this roundup)
- 4-6″ gap: Adjustable footrest at maximum height, or stacked footrests
- 6″+ gap: Consider a different chair with lower seat height, or a height-adjustable desk
Frequently Asked Questions
Can a footrest help with back pain?
Yes — if your back pain is caused by improper seating height. When your feet dangle, your pelvis tilts forward, flattening the natural lumbar curve and straining your lower back muscles. A footrest supports your feet at the correct height, allowing your pelvis to maintain its natural position and reducing lower back strain. However, a footrest won’t fix back pain caused by other factors (poor chair support, incorrect monitor height, etc.).
Should I use a footrest with a standing desk?
When sitting at a standing desk, yes — the same ergonomic principles apply. When standing, a footrest can be used as a foot rail — placing one foot on a low footrest while standing shifts your weight and reduces lower back fatigue. Alternating feet every few minutes is a simple way to make standing more comfortable.
Foam vs hard footrest — which is better?
Foam footrests provide cushioning and comfort but compress over time and offer limited adjustability. Hard (plastic/metal) footrests provide precise adjustability and durability but less comfort. For most users, a hard adjustable footrest with a non-slip surface is the better long-term choice — it maintains its height and angle indefinitely. Foam footrests are better for users who prioritize comfort over precision.
The Bottom Line
The Humanscale FM300 is the best footrest for users who want active leg engagement and commercial-grade quality. The Fellowes Professional Series offers the best adjustability at a reasonable price. For budget-conscious buyers, the ErgoFoam and ComfiLife provide comfortable foot support under $35. A footrest is one of the cheapest ergonomic upgrades available — if your feet don’t rest flat on the floor, it’s a no-brainer investment.
