I hope that the reviewer who said this was good for a rolling chair had better luck than me. On the weight of that review I ordered this item for use under my husband's desk chair over a berber carpet to replace a cracked old plastic floor protector thinking it would look very nice in his African themed den. Well he is not particularly heavy nor is his chair. But as soon as he started using it, the edges started to bend upward and it got so bad that we tripped over the edges every time we entered the room...I'm talking 4 inches off the floor at the outside edges. The center of the bamboo cracked a little and should be thicker if there is to be weight applied to it over anything other than a hard surface. This might be attractive and useful on a hard floor, but think a few times before planning to use it over a carpeted area including very low pile, firm carpet. I'm very disappointed.
