I'm 6'2" 220lbs and already there are massive dimples in the mat...almost like dents will keep an eye them to see if there is any cracking or perferation in those areas...and keep my eye on the warranty and glad I used my AMeX card because it doubles the warranty...probably only 30days... I guess you get what you pay for
The chair mat is in place and functioning as it should on an area rug. It does not move around during use. I can't speak to durability yet since I've only had it in use for about 10 days. It seems well made and it is definitely crystal clear. Hope it stays that way.
The mat is much too soft. The wheels on my chair make indentions in the mat and I can't roll my chair very easily. It also won't stay put on my carpet....keeps sliding around. I have to readjust every couple days.
