I purchased 2 of these mats and I really like them. They're clear and adhere to the carpet very well. My only complaint is the way they were delivered. They both came badly curled. Not rolled; that I could handle. But curled in several different directions. It made it very difficult to lay them down. These should either be delivered flat or rolled. Other than the delivery I like the mats.
Just laid the chair mat at my computer - I'm satisfied with mat for now however time will tell after extended use. I don't expect my 4-caster office chair to roll on the mat as easy as it would on hardwood floor.. Caster's still make an indention in the pad but not as deep as the thin pads I've experienced.in the past. What would be great is a mat that is more hard for use on top of 1-inch Berber carpet and padding.
Not too happy with the mat thought it would be thicker. We have very thin carpet w/no padding and with my weight (120#'s) on chair I sink into the mat leaving indentions and making it hard to roll around easily.
Although it came unpackaged and sitting on the floor of a van with cases of paper on top of it it did arrive in good shape. After about a week of use I see imprints of where the chair wheels sink into it. If it doesn't get worse it will be ok
