The mat was delivered with a hole/crack in the lip of it. It doesn't interfere with the chair movement. I did not return it too much of a hassle but I am disappointed.
This chair mat was just what we wanted and the price was right. Had a % off coupon that made it really work. Recently refinished the hard wood floor in my office space at home. Did not want to be running the chair wheels over the new finish. Initially used an area rug but that did not work. This mat is perfect. Width and length were just right and the lip on the edge allows an easy "recovery" if I rolled too far to the back or either side. Highly recommend this mat to anyone looking to protect a hard wood surface.
Bought 2 of them so my husband could move from his desk to his model table in his new chair he got for Christmas. Works great on the low pile carpet we have in that room. Mats are a nice quality heavy weight appear to be durable. We purchased one a few years ago for our laptop under desk and chair. Looks brand new and so we knew this would be a good purchase for us. You need mats when you have desk chairs sliding on floors or carpet that's why offices use them. We purchased them on a nice sale with Staples delivered very quickly we are more than pleased with them!
The chair mat I'd had for years finally cracked tot he point of not being usable any more. I ordered this one online and it was delivered the next day. Had to trim the lip just a little since I have a narrow entry on my desk but it was easy and it fits great. I provides great chair support and mobility even on the high pile carpet in my home office.
