It's perfect for the Berber carpet we have. The indentations left by chair wheels disappear after a while (how long will that last?). The lip is just a little too short for under the desk.
Recreational home use. Slight movement over a weeks time. Indents somewhat but does not affect ease of chair movement. Excellent value and very satisfied thus far.
came in a box folded....had to flatten out for two days....thought for the money it should have been thicker....leaves dents when on sitting on chair....
