I bought a similar mat for my carpet (from Staples) and it turned out to be too flimsy. The chair rollers sank into the thin plastic mat. So I returned it and upgraded to this "heavier" mat (again from Staples) which should be good for my 1/2 to 3/4" pile carpet. Unfortunately this mat isn't much thicker than the lower model mat and the rollers still sink into the mat and the chair can't move out of the depressions in the mat! Basically it's totally useless!! I'm tired of returning things to Staples so I've just given up and will eat the cost of the mat and try somewhere else... I can not recommend this mat to anyone.
I am not so sure that I should have bought this mat for the money I spent it is already dipping at the front/right chair wheel. This isn't what I had expected. I could have purchased a much cheaper mat than this.
I bought this chair mat to replace an old one that had cracks in it. I would have preferred one in this size with a ramped edge like my old one but it turns out that there is no problem rolling off and on the edge of the mat. I like that the mat is clear and it blends in with the carpet. I would recommend this product.
THIS IS NOT AS HARD OF A MT AS WE WANTED IT STILL DENTS IN WHEN YOUR OFFICE CHAIR IS ON IT . NOT TOUGH ENOUGH HARD TO ROLL ON. NOT REALLY HAPPY WITH ITEM. WOULD NOT RECOMMEND IT AT ALL.
