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!
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.
