My old chair mat was brittle & cracked finally falling apart. While this one seems more rugged it has flexibility that allows me to roll around no my chair but without making divots in the mat (or the carpet underneath it)
We had a previous better quality Staples chair mat and needed a new one so decided to try this less expensive mat. It slides on the plush carpet and even bends up against the computer desk. I would not buy this product again.
