Key takeaways
- Height range: Choose a model whose lowest setting is close to your measured gap, so you are not forced to lift your knees above hip level.
- Platform width: A wider platform lets both feet sit side by side and lets you shift position.
- Depth under the desk: Some desks have modesty panels or drawer units that cut into the available space. Measure from the front edge to any obstruction.
- Chair casters: A wide footrest in the path of your chair base can be knocked over. Keep it clear of the chair’s rolling zone.
- Flooring: Hard floors need a grippy base. Carpet can make rocking models feel unstable if the carpet is thick.
Pick a rocking, adjustable-tilt footrest such as the Humanscale FR300 or the Kensington SoleMate Plus if you want to move your feet and ankles through the workday, a fixed-angle foam or ergonomic wedge if you simply need your feet supported while a taller desk or chair leaves them dangling, and a budget textured platform if you only need a stable place to rest. The right choice depends mostly on three things: your height relative to your desk, whether you sit with your feet flat or tucked, and how much you fidget. This guide walks through the common footrest types, the models buyers most often compare, and the trade-offs between budget, mid-range and premium tiers.

Why a footrest matters at a desk
A footrest is useful when your chair seat cannot be lowered enough for your feet to rest flat on the floor while your elbows still sit at keyboard height. That often happens with fixed-height desks, shorter users, or chairs without a wide height range. Ergonomic guidance from workplace-safety bodies generally describes a seated posture where feet are supported, knees are roughly level with or slightly below the hips, and there is a little clearance behind the knees. A footrest is one way to reach that posture. It does not replace getting up regularly, and it will not fix a desk or chair that is the wrong size overall.
If you have persistent leg, back or circulation symptoms, talk to a doctor or physiotherapist rather than relying on an accessory. Nothing in this guide is medical advice.

The main types of under-desk footrests
Rocking and tilting platforms
These are the most flexible. A platform pivots on a base so your ankles move back and forth, and most allow you to change the height and the tilt angle. The Humanscale FR300 is the model many ergonomics retailers use as a benchmark, and the Kensington SoleMate Plus is the common mid-range alternative. The appeal is that you are not locked into one foot position for hours. The trade-offs are footprint and noise: a rocking base takes more floor room, and cheap versions can squeak or slide on hard flooring. Check that the underside has a grippy base, and place it on a mat or rug if your floor is smooth.
Fixed-angle wedges and foam blocks
A simple wedge raises the front of the foot and keeps ankles at a comfortable angle. These are light, inexpensive, and easy to slide away when you stand. Memory foam versions are popular with shorter users who find their feet barely touch the floor. The downside is that foam can flatten with daily use, and a fixed angle may not suit everyone. If you use a standing desk, a wedge is easy to tuck away.
Hanging hammock footrests
A hammock-style footrest attaches to the underside of the desk and cradles the feet in a mesh or fabric sling. It saves floor space and keeps cables and chair wheels clear. The catch is installation: it needs a solid mounting point, and it will not work on glass tops or very thin desk surfaces. Look at the mounting method the maker describes before buying.
Massage and roller footrests
Some models include roller bars or textured nodules. Reviewers often report that these are pleasant in the first week and then become something you stop noticing. If you share a quiet office, a roller can also be audible on hard floors.
Adjustable multi-height platforms
A step-style platform that you can set to several heights is worth considering if more than one person uses the workstation, or if you plan to change chairs. Look for a stable base, a non-slip top and a clear way to lock the height. Wobble is the most common complaint in user reviews of cheaper height-adjustable units.
How to size and fit a footrest
Sit in your normal working posture. Adjust the chair so your forearms are roughly parallel to the desk and your wrists stay in a neutral line when typing. If your feet do not reach the floor comfortably in that position, you have a case for a footrest. Measure the vertical gap between the floor and the sole of your foot, and the open depth under your desk.

Budget tiers
Budget
Foam wedges, simple slanted plastic platforms and basic hammocks sit here. They suit light use and shorter work sessions. Expect fewer adjustments and more wear over time. For many people with a modest height gap, a budget wedge is all that is required.
Mid-range
This tier includes the Kensington SoleMate Plus and several Fellowes models with adjustable height and tilt. You gain stability, a wider platform and more reliable moving parts. It is a good fit for full-time desk workers who want an upgrade from foam without paying premium-brand pricing.
Premium
The Humanscale FR300 lives in this tier. The maker markets it for office use with a durable construction and a smooth rocking action. Premium models make sense if you spend most of your day at the desk, share the workstation, or want a product that is designed to last for years.
Pick X if you…
| If you… | Pick | Why |
|---|---|---|
| Fidget and like to move your ankles | Rocking platform (FR300 or SoleMate Plus) | Allows continuous gentle movement |
| Are shorter and your feet dangle | Fixed wedge or step platform | Gives stable, level support at a set height |
| Have little floor space | Hammock sling | Mounts off the floor |
| Share the desk with others | Height-adjustable platform | Quick changes between users |
| Work at a sit-stand desk | Light, easy-to-move wedge | Slides aside when you stand |
| Are on a tight budget | Memory-foam wedge | Simple, low cost, adequate for light use |
Care and safety notes
- Wipe plastic and rubber surfaces with a damp cloth. Follow the maker’s cleaning guidance for foam covers, since some are removable and some are not.
- Do not stand on a footrest unless the maker states it is designed for that. Most are rated for feet only.
- Keep cables clear of rocking mechanisms so they cannot get caught.
- Change your position often. Even a good footrest is not a reason to stay seated for hours without a break.
- Stop using a product that causes pain or numbness and seek medical advice if symptoms continue.
Alternatives to consider
A lower or adjustable desk
If the problem is that your desk is too high, a height-adjustable desk lets you set the working surface to your body rather than raising your feet. This costs more but solves the root cause.
A chair with a wider height range
A chair that drops lower, or one with a seat-depth adjustment, may let your feet reach the floor. Check the maker’s stated seat-height range against your leg length before buying.
An anti-fatigue mat
If you mostly stand, a mat under your feet provides cushioning in a different way than a footrest. It is not a substitute when you sit, but it complements a sit-stand setup.
A balance board or active-sitting accessory
Some users prefer an active foot device that invites movement. These are best used for short periods, and the maker’s weight limits and safety instructions apply.
Common mistakes
People often buy a footrest that is too tall, which pushes the knees above the hips and tilts the pelvis backwards. Others choose a very narrow model that forces the feet together. A third mistake is placing the footrest too far forward so the legs are stretched out and the lower back loses support. Aim for a footrest that sits close enough that your knees are bent at a comfortable angle, and adjust gradually over several days.
Frequently Asked Questions
Do I need a footrest if my feet reach the floor?
Usually not. If your feet rest flat with knees near hip level and your arms are at keyboard height, a footrest adds little. Some people still like a rocker for movement, but it is optional.
Is a rocking footrest better than a fixed one?
A rocking footrest lets you shift position, which many users find more comfortable over a long day. A fixed footrest is more stable and quieter. Choose by habit: fidgeters tend to prefer rockers, and users who want to plant their feet prefer fixed.
How high should an under-desk footrest be?
Set it so your thighs are close to level with the floor and your knees are about the same height as your hips or slightly lower. Start low, because it is easy to go too high. If your knees rise above your hips, lower it.
Will a footrest work with a standing desk?
Yes, though you will likely move it often. A lightweight wedge or a portable platform is easier to push aside than a heavy rocker. Some people leave a rocker permanently under a sit-stand desk and simply step around it.
Can a footrest help with leg or back pain?
Makers sometimes describe comfort benefits, but a footrest is not a treatment. Improved support may feel better for some people, while others notice no change. If you have pain, numbness or swelling, see a doctor or physiotherapist.
How do I stop a footrest from sliding on a hard floor?
Choose a model with a rubberized base, or put a thin non-slip mat underneath. Keep the footrest out of the path of your chair’s casters. If it still moves, a hammock-style mount avoids the issue entirely.
