This is a soft plastic chair mat that when the chair sits in one position it causes dents. Overall it's overpriced for what you get. I would not recommend. This needs to be built thicker and stronger for the money.
The mat is a pliable plastic which gets easily indented does not stayin one place andthe edges curl up. After about 9 months of frustration I tossed it in the trash. I am sure Staples would have refunded the purchase price if I had asked but lifes gets in the way. Usually things from Staples are of a better quality.
