Similar to previous mat purchased at Staples a number of years ago that cracked after several years usage. Even though this is on low pile carpet it has indentations where the chair sits. Time will tell whether this will hold up as well as the previous one.
I weight 200 pounds and the mat hasn't cracked in 240 days. Pits form under the wheels when the chair hasn't moved but disappear when the chair has been moved.
This plastic rug protector was the exact size as advertised. It fit perfectly into the well where the previous rug protector was. The chair glides smoothly over it.
