The chairmat is adequate for the job. It is not as thick as it could be so my office chair wheels have made permanent grooves where they sit. I don't find it easy to roll on and I thought it was expensive for what I got. I didn't want to pay anymore money so I got the cheapest one they had.
I can't really say anything about this product because I haven't had it very long. the last time I bought this product was five years ago. I have berber carpet and a light weight office chair. at this time it seems ok.
*had very limited dollars to spend *was designed to be used on a thinner carpet but working well even with padding *have not owned long enough yet to rate durability *could be just a little larger especially the portion that fits under the desk
It's not thick enough so your chair sinks into it making it hard to roll around. Somebody needs to make a thicker/more solid mat. I would have returned it if I didn't need something right away to hold me over until I find a better product. I think the description on rug use is misleading.
