For the price this chair mat held up for a long time. We have purchased less expensive mats only to have them fall apart quickly. Very happy with the quality of the product.
I bought this to replace a mat that was falling apart. My old one had the nubs that gripped the floor but were kind of sharp and spiky. This one has flat nubs and I was thinking it was going to be a bad idea but I went with it because I had a coupon and it was on sale. After trying it I found that it works even better than the spiky nubs. It didn't scratch me when I opened it up to lay it flat and but it did grab the carpet as soon as I laid it down. It made it a little challenging to get it flat but after that it was easy to get it to lay flat. It was more flat so less of a challenge for the wheels of my chair to roll over which made it perfect.
I have bought this mat a few times seems to lasts about 6 months before starts to crack. It is great until that point however I am disappointed on how the price on all mats seems to be steadily going up and up.
Satisfied with this product. Got this for my children's room. Just as an advise review the location where this is to be placed. In my case the lip option was a bit difficult to use given that the child's (small) desk was partially above the chairmat making it a bit unstable at first. After a bit of adustment we now have the issue managable. A square shape would be have worked much better but it was just my oversight.
