Unfortunately the product is failing as the mat under wheel pressure leaves a "divot" impression in the mat and makes it difficult to move the chair. The thickness to prevent this issue needs to be at least twice as think. not a good product.
Very poor quality- chair wheels are making indentations in the chair mat and as a result my chair does not move smoothly over the mat. It is not thick enough/strong enough to support my desk chair. I am very disappointed with this product.
