Marvelux 36" x 48" Heavy Duty Polycarbonate Office Chair Mat with Lip for Carpets, 2 Pack, Clear Carpet Protector for Low, Standard and Medium Pile Carpeted Floors, Shipped Flat, Multiple Sizes

I was worried reading so many reviews stating their mat cracked, chair couldn't roll easily or had large dents from wheels. This did come rolled and had a warning to unpack very carefully due to it's being rolled under pressure. Unpacking was challenging and it did go flat immediately once released from it's binding. It was also challenging to place this very unflexible mat into the tight corner my desk is in, but I did manage it and since then I'm loving it. It is solid, no denting and my chair rolls easily. I have a large chair and I'm a hefty woman, so that is all a huge plus. I think the most important element to success with this mat is to be sure you purchase one for the correct depth of carpet. The spikes on the back of this mat seem to be the exactly right depth for my carpet to reach the flat subfloor and maintain a nice flat mat. Carefully measure your carpet depth and order the right mat and all will be right with your world!

Good mates to protect your carpet from your desk chairs. Durable, sturdy and long lasting.

This mat has been durable, however it has a MAJOR flaw. The entire front of the mat will no longer lay flat to the floor (see photo). The front of the mat were the tab is located actually curls up 3.5" and no matter what I do I can't get the mat to lay flat to the floor (carpet). It curls up so high that I have actually tripped over it several times. Also even though it has nibs on the bottom of the mat it still slides on the carpet! There is no excuse for this chair mat to have such poor quality at the price I paid for it. If I could give this mat zero stars I would!

This mat is definitely superior to many vinyl mats I have had in the past. As other reviewers have noted it does not dent, so you do not get trapped in one position, my chair rolls easily. I have now ordered my second mat, because the previous one developed about 15 parallel cracks, each about a foot long, in the center, after about two and a half years of use. That is still better than vinyl mats. Perhaps the perfect chair mat is an impossibility! ? The manufacturer has taken care of the previous problem of very sharp edges. The new mat has decent edges, rather than the knife-sharp ones the old one came with.

I am a retired resident in a Life Care Community -- not a work-at-home type. I bought this chair mat to protect the carpet and to allow me easy movement at my desk. I also replaced the wheels on my chair for better load distribution -- oh, and the load is about 160 lbs. For the first several months the mat was great, but then I noticed small cracks developing. You can see them clearly in the third photo. Given the nature of the materials, these cracks have gotten worse, and will continue to do so until I am forced to replace it. I am very disappointed -- less than a year of use on a product that I thought would be good for five years or so.

Be careful opening it up since it will unroll like a tight wound spring and you can get hurt.!!!! Besides that, it instantly laid down flat, my chair is rolling freely and it is thick enough not to get indentations from the wheels like cheap maps get. Overall, highly recommended and I will replace the rest of the mats in office and working area with those.

Good quality, but it slides around and I have to constantly move it back to its proper position. It will not stay where I put it. I will have to throw it out and buy a new one that works.

I've used this mat for months and it hasn't dented, gotten groves, cracked, yellowed or even shifted out of place. It still looks brand new! If you need a heavy duty, transparent, full size office chair mat that actually supports weight and will see a lot of daily use- this is the one. It's well worth the price. I put the second one under my craft room work bench. If I drop a tiny project component, I can easily spot it on the mat!

Bought these a few months ago to replace ones bought from Staples that had cracked over the years. We chose this one because we got two for a reasonable price and they shipped flat. The box it shipped in was a complete mess, but the actual product was undamaged (fortunately). We have two office areas on carpet surfaces. One is medium carpet density, but the other carpet is high grade and plush. These mats are very thin and I was worried that they would break the first time we sat in our chairs. But so far they have performed very well - no dents, no cracks, and they seem to stay in place fairly well. Maybe when it comes to chair mats, thinner is better because it creates less strain on the polycarbonate material. Pleasantly surprised by the performance of these chair mats so far!
