You’ve spent hours tweaking your chair height, adjusting your monitor, even investing in a decent keyboard — and your lower back still aches by 3pm. The missing piece might be the cheapest thing on this list: a desk footrest. Most people ignore what’s happening below knee level, but where your feet land has a direct impact on your spine, hips, and how long you can sit comfortably.

Why a Footrest Actually Matters for Posture
Here’s the thing most people don’t realise: if your feet don’t sit flat on the floor, your entire posture chain is compromised from the bottom up. Your thighs angle downward, your pelvis tilts forward, and your lower back compensates by curving more than it should. Over a full working day, that adds up fast.
The Biomechanics in Plain English
When your feet dangle — even slightly — the weight of your legs pulls on your hip flexors. Those tight hip flexors then tug your pelvis forward, flattening your lumbar curve. Your upper back rounds to compensate, your shoulders creep forward, and suddenly you’re the human question mark your physio warned you about.
A footrest brings the floor up to meet your feet. It keeps your knees at roughly 90 degrees, your thighs parallel to the floor, and your pelvis in a neutral position. The HSE’s display screen equipment guidance specifically recommends a footrest for anyone whose feet don’t reach the floor comfortably.
Who Benefits Most
- Shorter individuals — if you’re under about 5’4″ and your desk isn’t height-adjustable, your feet probably hover above the floor once you’ve set your chair to the right height for typing
- Anyone with a non-adjustable desk — standard UK desks are 72-75cm tall, which suits people around 5’10”. Everyone else is compromising somewhere
- People who cross their legs — crossing legs is usually a sign your feet can’t find a comfortable resting spot. A footrest fixes the root cause
- Those with circulation issues — a rocking or angled footrest encourages micro-movements that keep blood flowing through your calves
After using one for about six months at my own desk, the biggest surprise wasn’t the back pain relief — it was how much less fidgety I felt. My legs actually had somewhere comfortable to be.
Signs You Need a Desk Footrest
Not everyone does need one. If you’re tall enough that your feet plant firmly on the floor with your chair at the correct height, a footrest would actually push your knees too high and cause different problems.
You Probably Need One If
- Your feet dangle or barely touch the floor when your chair is at the right height for your desk
- You constantly cross your legs — this is your body searching for stability it’s not getting from the floor
- Your lower back aches after a few hours despite having a decent chair
- You tuck your feet under the chair or wrap them around the chair base
- You feel pressure behind your knees — the seat pan is pressing into the back of your thighs because your feet aren’t supporting enough weight
You Probably Don’t Need One If
Your feet rest flat on the floor with your thighs roughly parallel to it. In that case, adding a footrest would push your knees higher than your hips, which creates its own set of problems. A full ergonomic setup guide can help you figure out where you actually stand — or sit.
Types of Desk Footrests Explained
The range goes from a £10 foam wedge to a £150 heated massage unit. Here’s what actually matters.
Fixed Angled Footrests
The simplest type: a rigid platform set at a fixed angle, usually around 15 degrees. No moving parts, nothing to break. These work well if you mainly need something to plant your feet on and your chair stays at a consistent height.
The downside: because the angle is fixed, you can’t adjust it as you shift position throughout the day. If you like to recline your chair after lunch (no judgement), a fixed footrest won’t follow that change.
Expect to pay about £15-30. Kensington and Fellowes both make solid versions available at Staples and Amazon UK.
Adjustable Tilt Footrests
These let you change the angle — some with a lever, others with a textured surface that rocks freely. The adjustment means they work whether you’re sitting upright for focused work or leaning back for a video call.
I’ve been using an adjustable tilt model from Fellowes for over a year now. The rocking motion is subtle enough that you don’t notice you’re doing it, but your calves and ankles stay active. At about £30-50, they’re the sweet spot for most people.
Rocking and Active Footrests
These are designed to move. Some rock side to side, others pivot on a central point, and a few offer a full rocking-chair motion. The idea is that keeping your feet and lower legs moving prevents stiffness and improves circulation.
If you’re someone who fidgets — tapping feet, bouncing knees — a rocking footrest channels that energy productively. Humanscale makes a premium option around £80-100, and there are decent budget alternatives from Kensington around £40.
Heated Footrests
Exactly what they sound like. These combine a flat or angled footrest with a heating element. They’re particularly popular in home offices during winter, especially if you work in a room with hard flooring.
A word of caution: the heated ones tend to be bulkier and less adjustable. If warmth is the main draw, you might be better off with a good footrest plus a separate foot warmer. Expect to pay £40-80 for a heated model from Beurer or similar.
Foam Wedge Footrests
The budget option: a dense foam wedge that sits on the floor. No adjustability, no moving parts, but surprisingly effective for the price. They compress over time (usually 6-12 months of daily use), but at £10-15 they’re practically disposable.
What to Look for When Buying
Surface Texture
A smooth plastic surface means your feet slide around, especially in socks. Look for a textured or rubberised top surface that grips. Some models have a massage-bump texture, which sounds gimmicky but actually feels decent during long sessions.
Size and Stability
- Width — at least 40cm so both feet fit comfortably side by side
- Depth — 30cm minimum so your whole foot rests on the surface, not just your toes
- Anti-slip base — rubber feet or a non-slip pad on the bottom. Without this, the footrest slowly migrates across the floor and you spend half your day fishing it back with your feet
Height and Angle Range
If you’re buying adjustable, check the range. Most offer 10-20 degrees of tilt. The height when flat should be around 10-15cm — enough to bridge the gap between a standard desk height and shorter legs, without pushing your knees above your hips.
Weight Capacity
Most footrests are rated for around 5-10kg of resting weight (the portion of your leg weight that transfers through your feet). This isn’t like a chair where you need to support your full body weight. Even budget models handle this fine.
Best Desk Footrests in the UK
Best Overall: Fellowes Standard Footrest (Adjustable)
About £35 from Amazon UK or Staples. Three height positions, textured non-slip surface, solid build quality. It’s the one I’d buy again — not flashy, just works. The platform is wide enough for larger feet and the rocking motion is smooth without being distracting. If you want one recommendation and nothing else, this is it.
Best Budget: Kensington SoleMate
Around £25 from Amazon UK. Fixed angle but well-built. The SmartFit system lets you set it to one of three heights. Simple, affordable, and it’ll last. Good if you just need something solid under your feet and don’t care about rocking motion.
Best for Active Sitting: Humanscale FR300
About £80-100 from specialist ergonomic retailers like Posturite. This is a proper rocking footrest with a smooth pivot that encourages continuous micro-movements. If you fidget at your desk or want to keep your calves active, this is the one. Build quality is noticeably better than budget options — it feels like furniture rather than office supplies.
Best Heated: Beurer FW 20
Around £45-60 from Currys or Amazon UK. Combines a flat footrest with gentle warmth. Three temperature settings. It won’t replace a proper adjustable footrest for posture, but if your home office has cold floors between October and March, your feet will thank you.
Best Foam Wedge: Supportiback Ergonomic Foot Rest
About £15 from Amazon UK. High-density foam, velvet cover, decent angle. It’ll compress after 6-9 months of heavy use, but at the price, you can buy three for the cost of one adjustable model. Good entry point if you’re not sure whether a footrest will work for you.

Footrest vs Alternatives: Yoga Balls, Boxes & DIY Options
The Old Box-Under-the-Desk Trick
A cardboard box or stack of books under your desk does technically work. It brings the floor up. But it’s fixed height, no angle adjustment, and it looks like what it is — a temporary solution you never got around to replacing. If you’re testing whether a footrest helps before spending money, go for it. But don’t kid yourself it’s a permanent fix.
Yoga Balls and Balance Cushions
Some people put an inflated balance cushion under their feet as a footrest alternative. It does encourage active movement, but it also means your feet never have a stable resting position. For short periods that’s fine. For an eight-hour workday, you want the option to just plant your feet and focus.
DIY Angled Footrests
If you’re handy, a piece of plywood at a 15-degree angle with some non-slip matting does the job. There are plenty of plans online. The advantage is you can build it to your exact height requirements. The disadvantage is it looks like a piece of plywood with non-slip matting on it.
How to Use a Footrest Properly
Getting the Height Right
Start with your chair at the right height — your elbows at roughly 90 degrees when typing, forearms parallel to the desk. Then adjust the footrest until your thighs are parallel to the floor and your knees are at about 90 degrees. If your knees are higher than your hips, the footrest is too high.
Foot Placement
Both feet should rest fully on the surface. Not just your toes, not just your heels. The whole foot. If you find yourself perching on the edge, the footrest is either too small or positioned too far away.
Movement Is Good
A footrest isn’t a foot prison. Shift your weight between feet. Rock if your model allows it. The goal is a comfortable default position that you return to between movements — not a rigid locked-in pose. The best desk setups, as covered in our standing desk setup guide, combine multiple positions throughout the day.
Do You Need a Footrest with a Standing Desk?
When You’re Sitting
If you use a sit-stand desk converter and spend part of your day sitting, the same rules apply. Your sitting height probably still leaves your feet short of the floor, especially if the desk has a high minimum position.
When You’re Standing
A footrest bar — the kind you see in pubs — is actually brilliant for standing desks. Resting one foot on a low bar (about 15-20cm high) shifts your weight, opens your hip angle, and relieves pressure on your lower back. Some standing desk accessories include a foot rail for exactly this purpose.
Common Footrest Mistakes to Avoid
- Setting it too high — knees above hips puts pressure on your lower back. The footrest should bring your thighs to parallel, not above
- Using it as a leg rest — resting your calves on the footrest rather than your feet defeats the purpose. Your feet need to be flat on the surface
- Placing it too far forward — if you have to stretch to reach it, you’ll end up sliding forward in your chair. Keep it directly below your knees
- Ignoring the rest of your setup — a footrest compensates for one problem. If your chair is wrong, your desk is wrong, and your monitor is wrong, fixing your feet alone won’t save you
- Buying heated when you need ergonomic — heated footrests are flat and non-adjustable. If your primary need is posture correction, get a proper angled or rocking model first
Frequently Asked Questions
Are desk footrests worth the money? For most people who work at a desk full-time, yes. A £25-35 adjustable footrest is one of the cheapest ergonomic upgrades you can make, and it addresses a problem that even expensive chairs can’t fix — the gap between your feet and the floor.
What angle should a footrest be? Between 10 and 20 degrees works for most people. Start around 15 degrees and adjust based on comfort. The key test is whether your thighs end up parallel to the floor with your feet resting naturally on the surface.
Can a footrest help with leg circulation? A rocking or tilting footrest encourages small movements in your calves and ankles, which helps blood flow. The NHS recommends regular movement breaks for circulation, and an active footrest can supplement that between breaks.
Should I use a footrest if I’m tall? Generally no. If your feet already rest flat on the floor with your chair at the right height, adding a footrest would push your knees too high. Footrests solve the problem of feet not reaching the floor — if that’s not your problem, you don’t need one.
How do I clean a desk footrest? Wipe plastic and rubber surfaces with a damp cloth and mild soap. For foam wedge models, remove the cover and machine wash if the label allows it, or spot clean with upholstery cleaner. Let it dry completely before using.
