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.
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.
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.
