Office chairs have wheels so you can move without getting up. You roll in to type, swing round to a drawer and push back to stretch, all without lifting the chair or twisting in your seat. The trick is matching the wheels to your floor, and knowing when a chair is better without them.
This guide covers why office chairs have wheels, which castors suit carpet and hard floors, and when to choose glides instead.
What do you call an office chair with wheels?
Most people say swivel chair, wheeled chair or task chair. The trade calls the wheels castors. A chair on castors that swivels and adjusts for desk work is usually sold as a task or operator chair, like the ones in our task chairs range.
Why do office chairs have wheels?
Wheels let you change position easily, which makes a well set-up desk easier to use. The everyday benefits:
- Reach without stretching: roll to the pedestal, the printer or a second screen instead of leaning out of your seat.
- Face your work square-on: HSE advises keeping your screen and keyboard central so you don't twist your back. A chair that swivels and rolls makes it easy to turn your whole body.
- Get close to the desk: you can pull right in, rather than perching on the front of the seat to reach, then roll back when you're done.
- Change your view: roll back a little to change your distance from the screen, or turn away from a bright window.
Some everyday examples:
- leaning back to take a phone call;
- rolling to a shelf, a printer or a second work surface;
- turning to face a whiteboard or a colleague;
- moving with a height-adjustable desk as you switch between sitting and standing.
In shared spaces, wheels also make quick chats easier. Colleagues can roll over to look at a screen and roll back again, without dragging chairs across the floor. They can swap places for a minute, sketch out an idea together, or gather at a shared screen for a hybrid call, in view of the camera and close to the speaker.
Wheels help when you rearrange a room, too. Roll chairs into groups for a workshop, then back to the desks for focused work, or move them between desks and breakout areas.
Rolling is not the same as moving about, though. HSE says breaks or changes of activity should let screen users get up from their desks and move around, or at least stretch and change posture. A chair on wheels makes small shifts easy. It doesn't replace standing up.
If you have a back or joint condition, ask your GP or occupational health adviser what kind of chair you need.

Why do office chairs have five wheels?
Office chairs on castors almost always sit on a five-star base: five legs, with a castor on each. The usual reason is stability: five legs spread the chair's footprint more evenly than four, so it's harder to tip as you lean, turn and recline.
For screen users at work, stability is a legal point, not just a comfort one. The Display Screen Equipment Regulations say the work chair must be stable, and HSE's workstation checklist asks whether a chair has working castors or glides.
Choose castors to suit your floor
Use hard castors on carpet and soft castors on hard floors. The European castor standard for swivel chairs, BS EN 12529, sorts them the same way.

| Your floor | Choose | Why |
|---|---|---|
| Carpet | Hard-tread castors (type H) | Hard wheels roll freely over carpet pile. |
| Wood, laminate, tile or vinyl | Soft-tread castors (type W) | A softer tread grips and is kinder to the surface. |
| Any floor, chair must stay put | Glides | No wheels, so the chair doesn't roll. |
Check which castors a chair comes with before you order, especially for wooden floors. If you're unsure, our friendly team can tell you what's fitted as standard.
Deep carpet is the one to watch. Soft rubber treads can feel heavy and slow on a thick pile, so hard castors or a mat make more sense there.
Add a chair mat to protect the floor
A chair mat takes the wear instead of your floor. Pick one made for your floor type, big enough for the area you roll over, and lying flat: our carpet chair mat is a 2 mm studded mat, 1200 × 900 mm, and there's a clear hard-floor chair mat for wooden floors.
Check the room as well as the floor
Before you settle on wheels, walk the route the chair will roll. Look for:
- mat edges and door thresholds that catch the castors;
- cables across the floor, which wheels can snag or run over;
- clutter in the rolling area: keep the path round the desk clear;
- a floor that slopes or a desk on a raised platform. On these, a chair on wheels may drift or roll off the edge, so a chair without wheels, or a different spot for the desk, is the better choice.
When a chair without wheels is better
Choose glides, not castors, when the chair shouldn't move. Three common cases:
- High chairs: a tall draughting chair should stand firm. The maker of our draughting kits advises never using one on a chair with castors. Read more in our draughting chair vs office chair guide.
- Meeting and visitor chairs: chairs that are sat in briefly and lined up neatly usually stand on a cantilever frame instead of castors. See our visitor chairs.
- Personal preference: some people simply prefer a desk chair with no wheels. A set of onion glides replaces the castors on a five-star base.
Office chairs with locking wheels
Braked castors are a middle option. Some have a lever you flick to lock them by hand. Two other kinds brake on their own. Load-braked castors lock when you sit down and roll when the chair is empty. Unloaded-brake castors work the other way: they roll while you're seated and lock when you stand up, so an empty chair stays put. Our friendly team can tell you which kind fits the chair you're looking at.

Are office chairs with wheels ergonomic?
Wheels alone don't make a chair ergonomic. What matters is whether the seat and back adjust to fit the person using it. UK screen regulations expect a seat that adjusts in height and a back that adjusts in height and tilt. Here is how to check the fit, using HSE's posture guidance:
- Seat height: set it so your keyboard sits just below elbow height, with the seat supporting the front and back of your thighs evenly. If your feet then don't reach the floor, use a footrest.
- Seat depth: leave a small gap between the front of the seat and the back of your knees. HSE suggests 2 to 3 cm. A sliding seat lets one chair fit people with longer or shorter legs.
- Lower back: the back of the seat should give good support to your lower back. An adjustable lumbar pad lets you move that support to where you need it.
- Tilt and tension: a tilt mechanism lets the back rock or recline. A tension knob sets how hard you have to push, so a lighter or heavier person can get the same feel.
- Arms: armrests should let you pull in close. If they hit the desk edge, choose height-adjustable arms or an armless chair.
For a chair that several people share, check that its range of adjustment covers all of them. Compare the seat width, seat depth, height range and maximum user weight, where the product page lists them, with the people who'll sit in it.
What to check on a wheeled office chair
Look past the wheels to the parts that carry them. These are the checks we'd make:
- Base material: bases are usually nylon or aluminium. Most of our task chairs with a listed base are nylon.
- Gas lift: the seat should rise and fall smoothly and hold its height.
- Frame and castors: the chair should sit level and feel solid as you lean. Every castor should be firmly in its socket and roll smoothly.
- Frame materials: steel or a reinforced composite underneath is a sign of a sturdy build.
- Upholstery: think about who sits in it and how it will be cleaned. Look for mesh, fabric or leather that suits the room and resists wear and stains, and padding that still feels firm.
How long will a wheeled office chair last?
It depends on the build and the care. A cheap chair can fail early; a better-made one, looked after, usually lasts longer. That's why it's worth treating chairs as a long-term buy: sturdier materials and mechanisms mean fewer breakdowns and fewer repairs to arrange. Our guide to how long office chairs should last explains the signs a chair is past its best.
If you're buying for a whole office, sticking to one or two models makes spare parts, repairs and replacement budgets simpler to manage.
Will replacement castors fit?
A worn castor can be swapped rather than replacing the chair. To find one that fits, check three things:
- Stem diameter and length: the stem is the peg that pushes into the base. It must match the socket.
- Wheel diameter: bigger or smaller wheels change the seat height slightly.
- Fitting type: most office chair castors have a push-in stem. Pull the old one straight out and push the new one in. For a threaded or other fitting, follow the maker's instructions.
We sell chrome castors singly for chrome bases, supplied with fixings. Our onion glides have an 11 mm fitting, so check your chair takes that size. Glides need the same checks as castors.
Keep the castors rolling
Hair and carpet fluff wrap round the axles over time, and the chair starts to drag. Tip the chair over now and then and pull it out. While it's upside down, check for loose castors and worn treads. Our guide to cleaning your office chair covers the rest.
Pick the wheels for the room
For most desks, a task chair on castors matched to your floor is the right answer. Use glides where a chair must stay put, and a mat where the floor needs protecting. Browse our full range of office chairs to find one that suits your room.
