Reasonably priced: I bought this mat to replace a bamboo mat (looks like wood floor) for a L-shaped desk. The bamboo kept buckling. Was concerned on new mat because label stated good for carpet 1 1/2” carpet. I am here to tell you it has not moved 1 cm. Great product this far!
The plastic is quite soft so when I sit in the chair on the mat it creates an indentation. This helps to keep the chair in place but when I try to move the chair I have to push harder to get out of the depression it created. If my movement isn't significant the chair rolls back into the depression. I think the plastic needs to be firmer to get a higher rating than 2. Other than that it is a nice plastic mat!
