I put the chair mat in place and within hours a small crack developed! Since then indentations are developing and making it difficult to move the chair position. Would not recommend this product
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.
