I just put in down Saturday and it already has very large indentions where the casters roll. I do not think that should happen that fast. Yes it was a cheaper one and I should have gotten the better one for a deeper pile for the carpet. I did not think our carpet was that thick but I guess it may be. I will certainly take a good look at the next one I buy and it will be the better one. Wish I could exchange it but I do not know if the store will take it back. I am not sure but I think I have my receipt.
it is nicely designed but just too thin. wheels from chair sink into the mat and it is not easy rolling around on it. should be thicker at the price and much more stable.
Could be made of thicker material. The desk chair leaves dents in the mat that can be difficult to roll out of. This is the second one of these I've purchased and expect it to last a couple of years before it cracks and becomes unusable. It took me about an hour to clean the mat with some adhesive remover because the packing tape that's used for shipping was difficult to remove.
I like the size and shape of the mat but the material is so soft that the chair sinks in making it almost impossible to move (roll) the chair while seated in the chair.
