I purchased one several years ago for about the same price that is much stronger than this one. the wheels on the chair put dents in this pad regardless the thickness of the carpet.
Chairmat began to fall apart after about 2 years. Was not abused or used by person of excessive weight. Purchased a name-brand product about 10 months prior to this one and it is still in perfect condition.
I can't believe some of these reviews I received my mat flat in a box it's very heavy duty I weigh 225 and have a heavy chair and I don't sink into the mat. It's very thick and easy to roll around on. I guess i just got a good one. RP
The Staples Carpet Chair Mat is very suitable for the space under the chair at the computer on the carpet area. It is a standard space for the chair to be mobile enough while working at the computer and to maintain the carpet's integrity.
