It's not worth the money you pay the chair makes an impression in the mat while working @ computer you are stuck under this dip when you are not sitting it goes back to normal however I guess it protects rug not happy with this product at all!
This was the least expensive chair mat and also the only good size for my desk area. It works fine but almost immediately the weight of the occupied chair created dents in the plastic which the chair rolls into. A minor annoyance and much less inconvenient than using an office chair on carpeting or spending more money. Overall good value for the money.
I purchased this for my home office. While it seemed like the cost would ensure its quality I did not find that to be true. The chair makes indentations on the mat. Trying to move the chair is difficult as the wheels get stuck in the grooves. My real fear is that the wheels will make holes in the mat. I would not recommend this product as I feel that it is not going to last very long.
After I got the mat to lie down on the floor - it has been very good. Might have liked a direction to put the mat out somewhere to "unroll" before I tried to put it under my desk. Getting it in place at the beginning was a real challenge. Also like that the edge is very low so my foot does not catch the edge.
