Are footrests bad? What the research actually says

The internet's most repeated footrest complaint is real, but it targets one bad type of footrest, not the idea itself.

"Are footrests bad?" pops up constantly in office-chair forums, usually followed by a comment insisting they confine your feet and wreck your posture. It's a fair question to ask before spending money on one, and the honest answer is more specific than yes or no. The complaint is real, but it targets one kind of footrest, not the whole category, and it skips over what happens when your feet dangle all day with nothing under them.

I write about desk gear for a living, not medicine, so I won't tell you a footrest will fix your back. What follows covers where the "footrests are bad" claim comes from, what the actual research says, and when ergonomists agree you genuinely don't need one. It also gets into why the fix for a rest that traps your feet is a footrest built to move.

The short answer

Where the "footrests are bad" idea comes from

Search "are footrests bad" and you'll land on threads like r/OfficeChairs, where a common answer runs some version of: footrests confine your feet, keep them locked in one spot, and get in the way of shifting position through the day. It's not a made-up complaint. Anyone who has used a flat plastic box or foam wedge under a desk for a few months has probably felt it: your feet end up stuck on a small platform, and moving them off it just puts them back on the floor at the wrong height.

The complaint gets repeated so often it hardens into a rule: skip the footrest, fix your chair instead. That advice is half right. Checking chair height first is genuinely the right move. But the footrest people complain about is one that didn't move, and that's a design problem. It says nothing about whether resting your feet on something is a bad idea.

What the research on footrests actually shows

Here is where the online consensus and the actual literature start to diverge. Nobody has published a large trial declaring footrests harmful. What exists is a small body of research on specific effects, worth knowing before treating the internet's blanket "bad" verdict as settled fact.

Study	What it looked at	What it found	The honest caveat
Wang, Lavender, Sommerich & Rayo (2022)	Footrest use during computer tasks	Increased use of the chair's backrest and pelvic rotation toward it, changing spine posture	No change in muscle (EMG) activity was measured; the authors describe a potential to reduce spinal load, not a proven reduction
Yamaguchi et al. (2014)	Leg swelling at three footrest angles (0°, 15°, 30°)	Swelling decreased at a 30° footrest angle versus flat	Small study, six participants; a signal worth noting, not large-scale proof
Fewster, Riddell, Gallagher & Callaghan	Cyclic footrest use during prolonged standing	Alternating foot position helped offset standing-induced low back fatigue	Studied standing, not seated desk work, so it supports alternating position generally rather than confirming it for sitting

Put together, none of this points to footrests causing harm. The picture that emerges is a device that, at best, nudges posture and swelling in a helpful direction, with effects that are real but modest and still being worked out. The complaints driving "are footrests bad" searches have less to do with physiology and more to do with a specific design flaw: a rest that locks your foot in one spot for eight hours.

When a footrest genuinely isn't the fix

To be straight about it: a footrest isn't for everyone, and the people who say "just fix your chair" aren't entirely wrong. Cornell Ergonomics puts it plainly: "In the vast majority of situations you should not need a foot support." Their guidance is to adjust chair height first, so the knees sit level or slightly below the hips and the feet land flat on the floor. If that setting already works, adding a footrest just adds clutter under the desk.

OSHA's computer workstation guidance lands in the same place: a footrest is the fallback "if the seat cannot be lowered enough" to let your feet rest flat. Mayo Clinic says the same thing, recommending one "if your chair is too high" for your legs to reach comfortably. All three sources point to the same specific mismatch, a chair too high relative to your legs. None of them treat a footrest as a default accessory everyone needs.

The test is simple: sit in your normal chair, at your normal desk height, feet unassisted. If your soles land flat on the floor with your knees roughly level with your hips, you probably don't need a footrest, and no amount of marketing copy should talk you into one. If your feet dangle, rest on their toes, or you find yourself tucking one leg under you because there's nothing to plant them on, that's the real signal a footrest is solving something.

The real complaint is about static, undersized rests

Read enough footrest reviews and a pattern shows up: the complaints track which specific model someone bought, far more than whether footrests work in general.

The recurring gripes: a rest too narrow to fit both feet, a foam pad that squashes flat within months, a plastic shell that cracks or slides across the floor, and, at the center of the "are footrests bad" thread, a fixed platform that pins your feet in one position with nowhere to go.

That last one is the real target of the confinement complaint, and it's fair. A flat static box locks your ankle at one angle for as long as your feet are on it. If you like to shift position, stretch your calves, or fidget through a long call, a static rest can feel like a small trap. Picking a footrest built to move fixes that, rather than giving up on footrests altogether.

Rocking vs. static: solving the confinement complaint directly

A reversible design is the practical answer here. The KomfiNest bamboo footrest flips between two modes: a curved rocking base for active movement, and a locked-flat static side for when you want a still, stable platform. Rocking means your ankle isn't held at one angle all day; you can roll your feet forward and back, work out a calf stretch, or just fidget without lifting off the rest entirely. Flip it over and lock the knobs, and it behaves like a conventional static footrest for calls, focus work, or anyone who prefers stillness.

It won't turn a footrest skeptic into a fan overnight, and switching modes takes an honest thirty seconds of loosening and retightening turn-knobs rather than one smooth flip, so it isn't something you'll do mid-call. But it answers the real objection behind most "footrests are bad" posts, which is about being stuck in one position rather than about resting your feet at all.

Bamboo vs. plastic and foam: why the material shapes the complaint too

Material plays into the same story. A thin plastic shell flexes and can crack under a full day's weight, and it tends to skate across hard floors, both of which show up in reviews as reasons people swear off footrests entirely. Foam feels great at first, then compresses over months until it's shorter than the gap it was bought to fill, defeating its own purpose. Solid bamboo avoids both failure modes: it holds its shape under repeated weight, and it's heavy enough, combined with grooved floor grips, to stay where it's put instead of sliding. None of that makes bamboo magic, but it does mean the footrest itself isn't adding a new problem to solve.

Getting the height and angle right actually matters

A footrest set at the wrong height can genuinely make things worse, which is part of where the "bad" reputation comes from too. Too low and it does nothing; too high and it pushes your knees above your hips, tipping your pelvis backward. Cornell and OSHA don't publish an exact number, but ergonomics consultants who do put a comfortable footrest height in the roughly 2 to 5 inch range for most seated desks, with an adjustable angle from flat up to around 30 degrees depending on whether you want posture support or a calf stretch. A footrest with only one fixed height and angle is guessing on your behalf; one with a few adjustable settings, like KomfiNest's three tilt angles, lets you find the setting that closes your foot gap instead of creating a new one.

What a well-built footrest looks like up close

Solid bamboo construction, reinforced groove joints instead of screws alone, and a 250-pound weight rating are the practical difference between a footrest you trust under your full weight and one you're gentle with out of habit.

It's also one reason people stop distrusting footrests once they've used a well-built one: nothing about a solid, sixteen-inch-wide, furniture-grade rest feels like the flimsy plastic box that started the complaint in the first place. If you're weighing whether to try one at all, it's worth looking at the current specs and price before assuming every footrest behaves the way a cheap one does.

Key takeaways

• Footrests aren't shown to cause harm in the research; the "bad" reputation traces mostly to static, undersized, or poorly fitted rests, not the concept itself.
• Cornell Ergonomics and OSHA both frame a footrest as a fix for one specific mismatch: a chair that's too high for your feet to reach the floor.
• If your feet already sit flat with knees roughly level to your hips, you likely don't need a footrest at all.
• The "confining" complaint is real for locked static rests; a reversible rocking-and-static design like KomfiNest's answers it directly by letting your ankle move.
• Height and angle matter more than most buyers expect; an adjustable rest lets you correct for a bad fit instead of guessing once and living with it.
