Two weeks after getting the mat it's still curling up on the edges. It was very difficult to get unrolled. I even used a hair dryer to help it along (which did work to some extent). For the most part it's probably going to be OK.
It does the job but already have indentions from my office chair into the plastic causing dents and slowing the roll - would not purchase again - i have had it for about 3 weeks.
The chair mat for hard floors is perfect. My desk chair with wheels was beginning to damage my wood laminate floor. This mat fits perfectly and will provide protection.
We needed a mat that could go under my wife's office desk that can reduce the wear on the carpet. This mat is sturdy doesn't slide and does the job. Can't complain.
