I sm using it now on a low pile commercial carpet until i have my hardwood floor installed and it feels good already if i stay in one spot too long small divots form (due to carpet underneath i beleive) but as i move the mat regains smooth surface immediately. Nice smooth quiet glide and cleaning is a breeze.
Soooo far the mat has worked well for me....no slipping wheels of the chair roll much better now and it stay flat to the floor i.e. Ends do not curl up. Well worth the $$ I spent. I do recommend this product.
The product proved to be just what I needed. It was a great size color and is proving to be of great quality. The Staples delivery was fast and overall the order is a great value.
I have no complaints. I'm using this over a rug and it works fine. just make sure you lay it out for awhile before rolling over it so that it doesn't crack.
