Choosing an Office Rug: Castors, Noise and Wear
An office rug has to survive a rolling chair. That rules out long pile, viscose and silk, and rules in dense low-pile weaves, flat-woven kilim and hard-wearing tile. Acoustics pull the other way, because a thicker cut pile absorbs more sound. Where castors travel, durability decides; where people sit still, the pile can rise.

Most advice about office rugs is really advice about atmosphere — what color reads as focused, what pattern reads as creative. Atmosphere is the easy part. The hard part is that a task chair puts the weight of a seated adult onto five small wheels and then drags them back and forth over the same square meter, eight hours a day, for years. This page starts there.
What a rolling chair does to a rug
It concentrates load and then abrades it. Those are two different kinds of damage, and different constructions fail at each.
An occupied chair puts roughly 80 to 110 kg through five castors. Each contact patch is a few square millimeters, so the pressure at the point of contact is far higher than anything a foot produces. Under that pressure the pile is crushed flat. Whether it comes back is a property of the fiber: wool has a natural crimp and recovers from compression over hours or days, while viscose, bamboo-viscose and Tencel are spun for luster and drape rather than resilience, and stay flat. The second mechanism is abrasion. A castor does not just press — it rolls, and rolling drags fiber ends against each other until the tips break and the pile mats into a permanent shine along the chair's arc.
Castor type matters more than most buyers realize. The European standard for swivel-chair castors, EN 12529, distinguishes type W castors, which are soft and intended for hard floors, from type H castors, which are hard and intended for textile floors. A chair sold with soft castors and then used on a rug grips the pile instead of rolling over it, and drags. If a rug is going under a chair, the chair needs hard castors.
The failure mode to design against is neither of these, though. It is the rug edge under a castor. A rug sized so that the chair's rear wheels cross the border ten times a day will lose that border first — the selvedge lifts, the wheel catches under it, and the rug is finished at the edge while the field is still new. Every sizing decision below exists to keep the castors inside the rug.
Which constructions survive a desk chair
| Construction | Under a rolling castor | Sound absorption | Verdict |
|---|---|---|---|
| Machine-woven, low dense pile (polypropylene, polyamide) | Recovers well; no visible track for years | Low | The default under a desk, and the cheapest to replace |
| Modular tile, cut and laid wall to wall | Built for it | Low to moderate | Open-plan floors where one damaged unit can be swapped out |
| Flat-woven kilim, wool | No pile to crush, but the weft abrades and the ends lift | Lowest of the group | Only over a full underlay, and better outside the chair zone |
| Hand-knotted wool, short dense pile up to 10 mm | Survives with rotation; wool recovers from compression | Moderate | Executive rooms and meeting rooms; workable under a desk if the pile is short |
| Hand-knotted or loom-woven wool, long pile; shaggy | Mats permanently along the chair's arc | High | Not under a chair, at any price |
| Viscose, bamboo-viscose, Tencel | Flattens and does not recover; marks with water | Moderate | No. These yarns are for luster, not abrasion |
| Silk | Crushes and shines irreversibly | Moderate | Rooms that are looked at rather than rolled across |
One usage note, since the trade uses the word loosely: a modular tile laid wall to wall is carpet in the strict sense, cut and fixed to the room. Everything else on this page is a rug, laid loose and liftable. The distinction decides who cleans it and what happens when you move.

Sizing: the chair's travel sets the number
Measure how far the chair rolls back, not how far the desk extends.
A single desk. A desk of 160 × 80 cm (5'3" × 2'7") with a task chair needs the rug to run the full desk depth plus the chair's travel. A five-star base is about 65–70 cm across, and a chair pushed back far enough for someone to stand puts its rear castors roughly 110 cm (3'7") behind the desk edge. So: 80 + 110 = 190 cm of depth, and 160 + 30 either side = 220 cm of width. Rounded to stock, a single-desk rug is rarely useful below 200 × 250 cm (6'7" × 8'2"), and 200 × 300 cm (6'7" × 9'10") is the safer buy.
A meeting table. Chairs at a table get pushed right back, so allow 75 cm (30") of travel on every side. A table of 300 × 110 cm seating ten to twelve therefore needs 300 + 150 = 450 cm by 110 + 150 = 260 cm — call it 300 × 450 cm (9'10" × 14'9"), or about 13.5 m². That is larger than the 10 m² usually quoted for a table that size, and the difference is exactly the strip where the rear castors would otherwise ride the border. If the room cannot take the full rectangle, put the rug in the seating area instead and leave the table on the hard floor. A rug that is nearly big enough is worse than no rug at all.
A round table. Table diameter plus 150 cm. A 120 cm (3'11") round table wants a 270 cm (8'10") circle. See round rugs, and square rugs for square reception areas, where 200 × 200 cm and 250 × 250 cm are the working sizes.
The old rule that a rug should cover about a quarter of the floor is worth keeping as a check on the total, once the chair arithmetic has produced the individual pieces.
Noise: what a rug does to an open-plan office
It absorbs some of what hits it and blocks most of the footfall — and the pile that does this best is the pile a chair destroys fastest.
The measure usually quoted is the noise reduction coefficient, or NRC, an average of how much sound a surface absorbs rather than reflects. Ordinary office rugs sit around 0.15 to 0.20. A thick, densely woven rug laid over an underlay can exceed 0.40, and 0.40 is the figure acoustic consultants generally set as a target for open-plan floors, alongside wall panels — a floor alone will not fix an open-plan room. Cut pile absorbs more than loop pile, which is why meeting rooms and quiet corners are where a deeper pile earns its place.
The second effect is larger and rarely mentioned. Most of what makes a hard-floored office unpleasant is impact noise: heels, chair legs, a dropped folder. A rug and its underlay stop that at the source, and they do it whatever the NRC says.
So the two requirements genuinely conflict, and the resolution is to zone the floor rather than compromise across it. Low, dense construction under the desks and the chair runs; deeper wool pile in the meeting room, the quiet corner and the waiting area, where nothing rolls.
The executive room, the meeting room and the waiting area
These are the parts of an office where a hand-knotted rug belongs, because nothing rolls across them for eight hours a day.
An executive room is the one place in a building where the floor is expected to say something, and over twenty years the motifs chosen most often for them have been Afghan, Turkmen and Oushak — dense, dark, bordered drawing that holds up under furniture and reads as considered rather than decorative. Browse Oushak rugs, Turkmen rugs and Afghan rugs. Where the room is minimal, a plain or quietly geometric hand-knotted rug does the same work in the opposite register. Silk belongs here or nowhere: it is for the room that is looked at.
Waiting areas take more traffic than they look like they do, and the arriving shoe is the dirtiest object in the building. Mid-tone and darker colors, patterned rather than plain, and a construction that can be lifted and washed. Pale, fine rugs in a waiting room are a decision to replace them.
Certificates, cleaning and rotation
Read what a certificate covers, and note what it leaves out.
Corporate specifications increasingly ask for documented low emissions of volatile organic compounds from floor coverings, and building rating systems such as LEED and the WELL Building Standard reference them. GREENGUARD Gold and comparable schemes certify that a product's measured emissions fall below stated thresholds. That is a statement about chemistry, tested under defined conditions — nothing more and nothing less. If a supplier offers one, ask for the document itself and check the product it names. Rugs woven from wool, cotton, jute and bamboo start from low emissions by construction; a synthetic rug is where the paperwork is worth requesting.
Maintenance in an office is mostly rotation. Vacuum in one direction with the hard-floor head rather than a beater bar. Move the desk and table feet a few centimeters every few months so the crush marks do not set in one place. Blot spills rather than rubbing them, since rubbing drives the liquid down into the knot collar. Keep solvents off the pile, and send a hand-knotted wool rug to a professional washer when it needs it — how a rug is washed covers what to expect.
Frequently asked questions
Can you use a desk chair on a rug?
Yes, on the right one. A dense low pile of 10 mm or less handles castors well, and the chair should be fitted with hard castors, which the castor standard types as intended for textile floors. Long pile, viscose and silk will not survive the load.
What size rug goes under an office desk?
Allow the desk depth plus about 110 cm behind it, so the chair's rear wheels stay on the rug when it is pushed back to stand. For a 160 × 80 cm desk that is a rug of at least 200 × 250 cm, and 200 × 300 cm is safer.
Which rug material lasts longest in a busy office?
Densely woven synthetic yarn in a low pile lasts longest under rolling traffic and is the cheapest to replace. Among natural fibers, wool is the most durable, because the crimp in the fiber lets a crushed pile recover.
Do rugs reduce noise in an open-plan office?
They reduce footfall and chair noise at the source, and they absorb some reflected sound. Ordinary office rugs measure around 0.15 to 0.20 NRC; a thick rug over an underlay can exceed 0.40, which is the figure usually targeted for open-plan floors alongside wall panels.
What size rug does a meeting table need?
The table footprint plus 150 cm on each axis, so that every chair keeps all four castors or legs on the rug when pushed back. A table of 300 × 110 cm therefore needs roughly 300 × 450 cm.
What does a GREENGUARD certificate on a rug mean?
It means the product's measured emissions of volatile organic compounds fell below the thresholds the scheme sets, under its test conditions. It is a statement about chemistry rather than about anything else, and the document should name the specific product.
Which rug suits an executive office?
A hand-knotted wool rug, most often in Afghan, Turkmen or Oushak drawing, or a plain modern piece where the room is minimal. Nothing rolls across an executive floor for hours at a time, so pile depth and fineness can be chosen for appearance.
