– Marvelux 90 x 120cm Premium Polycarbonate Chair Mat, Heavy Duty Office Chairmat for Medium Pile Carpets, Durable Clear Rectangular Carpet Protector Mat, Made in the UK

I only write reviews where I think there is something important to say and to provide the sort of information and advice that I would wish to see as a prospective buyer. This product does exactly what I wanted, which was the protection of a carpet that was being damaged by an office chair on castors. I am reviewing here the Heavy Duty Premium Polycarbonate version suitable for low, standard and medium pile carpets. Do not be misled by the reviews talking about dents or cracking, which I can only assume relate to a lower spec or faulty product. My previous protection lasted for a few years before starting to crack and break up but within days had shown denting from the castors. It was thicker than the product I am reviewing here but had channels in it that seemed to allow the formation of dents. I have been using this product for over a week, sitting in the chair for long periods and there are no signs at all of any denting, thus allowing the chair to move freely. The protector has small spikes underneath that keep it absolutely securely in place with no signs of any movement. So far, it appears to be an absolutely first class product. My advice would be to buy with confidence!

Great product! Stils well to the carpet, good quality. I’ve been using it for a long time won’t my heavy office chair and it’s protected the carpet well. Good size too.

Not cheap but seems to be high quality. Really helps to protect the carpet. It grips well so won't move around. I bought mine to replace another mat that had cracked and started to fall apart after about 15 years of regular use. This one looks almost identical so hopefully it should last a similar length of time.

I used to buy my carpet protector mats from Costco. They were in the region of £45 each, and generally lasted a year before showing any fatigue, but then rapidly deteriorated. I switched to using mats from Amazon, but was disappointed time and time again. The first mat I ordered stated it was fine on all surfaces, but started cracking within a couple of weeks. The second mat I ordered was flat out dangerous and was constructed of absolutely rigid, brittle plastic. It shattered as soon as weight was put on it. Again, it was advertised as being safe for use on carpet. The third mat I ordered was basically very soft vinyl, offering no real protection to the carpet. This mat, on the other hand, is exceptional. Its flexible enough to not crack as you move around, but firm enough to keep the chair perfectly mobile. Its not slippery, and crucially it *will not move* - even the Costco mats, the best to date, used to move around as you moved the chair. They would invariably end up shuffling into the edge of the desk or some other furniture and start to bend. This mat hasn't moved since I've placed it. As long as this one lasts at least a year, I'll be happy.

This product was bought as needed something strong to take a transportation hoist used at home - this mat hasn't disappointed. The hoist was very hard to run over a carpet when transporting an elderly person from a chair to bed. With this mat there is no jerky movement and is a smooth ride. It is strong and doesn't dent from the heavy wheels.

After just a few months, large cracks started appearing in the polycarbonate. There are now several cracks within the plastic. Such a shame, as it looked quality when it first arrived. The cracks are annoying, and they make a noise when the wheels pass over them. At the price paid, I expected much better. The dimples don't fully work. Over time, the mat does move, and eventually you have to work it back into position. I reported these issues at the time, but the seller refused a replacement. What a shame. They had the chance to put this right, but didn't take it.

This mat works perfectly under a desk on a thick carpet. The studded underside keeps it firmly in place, and the material is strong enough that chair wheels don’t sink in at all. It feels solid and durable, giving complete protection without any movement. I’ve used a smaller version in another room and it performed well for years, so when I needed a carpet mat for a larger desk I got the larger size with full confidence.

I have an Anda Seat Phantom 3 with "Amazon's Choice" for office chair wheels (from LifeLong store) which are rated a 4.7 star at the time of writing. I weigh about 80kg. I think this is a pretty standard setup & weight to have on the mat, evenly spread across the 5 casters. The mat looked good, durable and sat evenly across my low to medium pile carpet upon opening. The mat functioned well, but then cracked once within the first month of owning it which pictures are attached for. It has now developed 2 other cracks within the following month, one nearby and one on another area of the mat. I do not think this product is good quality considering the multiple failures of the plastic sheet. I've had similar ones when I worked in a company office and never cracked, so it seems either the one I was delivered had some manufacturing failures or is not well specified for the advertised purpose. The return window is only a single month, so I've missed the opportunity to raise this to the seller as a defect. I purchased the largest size for £69.99 and regret this purchase.
