Chair Mat Polycarbonate with Lip
£88.00
Our most durable chair mats, made from Polycarbonate which will not split, crack or curl. Lip design to fit under your desk and provide floor protection where you place your feet. Protect your carpet from the damaging effect of chair legs and castor wheels.
Size 89 x 119cm.
Protect your carpet from heavy castor wheel wear, chair legs, spills, and daily foot traffic with our highly-durable Polycarbonate Chair Mats with Lip. Featuring an extended lip section, this mat fits neatly into the desk footwell to provide extra protection right where you place your feet.
Engineered to lay flat straight out of the box, these clear mats offer smooth, ergonomic chair movement to reduce leg fatigue while allowing your carpet to show through seamlessly. Unlike standard PVC alternatives, high-grade polycarbonate is built for long-term impact resistance, won’t yellow or curl over time, and is completely free of unpleasant chemical odours.
Key Features & Specifications:
- Ergonomic Glide: Smooth surface reduces strain on legs and back when moving in your desk chair.
- Extended Lip Design: Fits into the desk well for added carpet protection where your feet rest.
- Carpet Protection: Shield carpets against scuffs, scratches, chair legs, and castor wheel indentation.
- Claw Backing: Studded underside grips carpet securely without damaging fibres (suitable for carpets up to 12mm deep including underlay).
- Instant Setup: Heavy-duty construction lies flat immediately upon unboxing.
- Discreet Design: Clear finish blends naturally into any home or commercial office setup.
Important Usage Notice:
Designed for use with office chairs and standard seating. Do not place stationary desk legs or secondary heavy furniture (such as bookcases or filing cabinets) on the mat alongside your chair. Shared weight distribution creates uneven pressure points across the material, which can cause premature cracking and void the warranty.
Ideal applications:
- Industrial, commercial or domestic
- Offices
- Carpets (claw back):
- Up to 12mm inc. underlay
How to Choose the Right Chair Mat:
Measure:
- Total floor space
- Workstation width
- Size of chair base
- ‘Roll area’ – how far you’ll move on your chair
- Carpet depth, including underlay
How to measure your carpet and underlay depth:
- Straighten a paperclip as shown below.
- Insert the paperclip through the carpet and underlay until it touches the subfloor.
- Measure the depth from the point where the paperclip touches the subfloor to the top of the carpet pile.
- Choose a chair mat option suitable for your total measured depth (e.g., select “Up to 9mm” if your total depth is 9mm or less).

Mr Golder –
First class service and quality from the beginning to the end. Quality mat for our home office chair.
Brian Brown –
Did just what it said on the tin. Perfect.
Donald McLaren –
My mat arrived within 48 hrs, well-packaged and in good condition. Since unrolling and installing under my desk and desk chair it has performed perfectly. I just wish I’d searched for one years ago and avoided wrecking a couple of carpets!
Judy Birkenhead –
I’m delighted with my computer mat which fits beautifully under my computer chair and desk. The chair moves around so much easier now. It really is excellent quality and my new carpet is no longer scarred by computer chair caster indentation marks.

Returning customer.
This is an excellent office chair floor mat, having tried loads of others, this has been the only one that doesn’t break or crack immediately, the previous one I bought also from here, lasted for over 4 years of constant use, which is very good considering the heavy chair and being used for several hours a day, its real value for money as well.
Very fast shipping and delivery as well.
I would and do highly recommend it.

Bought a chair mat from Trusted Mats to protect a new carpet. Works very well and if a little pricy at £77 is well worth the difference. In particular it came rolled up under tension and really did spring out flat immediately on removing the tension, as opposed to other possibilities which seem to be the devil’s own job to unroll and get flat. Very good service as well from a newish and I think small company. Highly recommended.

Chair mat review
Service was good and quick. Product was of high quality and reasonably priced for the quality. Above all it was send under tension so that it really did go flat when said tension was removed. Unrolling and getting flat can be a serious problem with some other supplies so that is a major bonus point. Highly recommend this business
Wendy Maclean –
Bought 2 chair mats to protect a mid pile carpet. The customer service is brilliant as respond to queries quickly and delivery is prompt too. The mat is the best product I’ve used to date and is good quality. I can 100% say our carpet is fully protected and comes up a treat after a quick hoover. If you are looking for carpet protection this is the product for you.
Lesley Hildrew –
Lovely new mat for my transporter. Quick delivery
David –
I bought the studded version for a new short-pile carpet in my home office. It works beautifully to protect my new carpet from the chair wheels. Should have had one of these years ago!
Michael Smalley –
Bought this top quality polycarbonate mat to protect our oak flooring – arrived on time and stays flat on floor and stays in place – tough but unobtrusive – many inferior mats out there but this one could not be bettered.
David Ellis –
Good mat but with slight problem.
The mat ordered was a “Chair Mat Polycarbonate with Lip”. It was delivered promptly and is of very good quality, enabling my desk chair to move around easily on its casters. I can see it will last a long time. However, I do have a bit of an issue with it (hence 4 stars and not 5). It doesn’t stay in place (at least not on my carpet). After a few hours it has moved out of position sufficiently for me to need to lift the chair off it and reposition the mat. The dimples on the underside, which I assume are there to hold the mat in place, don’t seem sufficient to do the job.
John Udale –
Very pleased no problem recommending
Very pleased with the product and the service.
I initially bought a rectangular chair mat, but when I got it I realised that it wasn’t the right mat for me. I contacted Trusted Mats and got a quick reply telling me what to do. I returned the rectangular mat and bought one with a lip, which is perfect.
Both deliveries were very quick, and the refund was almost instant when they received the returned mat.
Recommend them.
customer –
Great choice of mats. Mine arrived promptly, was exactly as described and was sent with really good (very pertinent) unpacking instructions.
Nigel Dyer –
I needed mat for my desk chair on new luxury carpet. It had to be of sufficient quality not to ruck up and to be delivered flat. I’m very pleased with mat supplied. Ticks all the right boxes.
