Swtroom Office Chair Mat for Hard Floors (36 inch X 48 inch Rectangle), our hard floor cushion is soft and strong enough to provide good protection for your hard surface floors (hardwood floor, ceramic tile, laminated floor, concrete, vinyl base plate, etc.). It is very easy to unfold and clean. At a comfortable room temperature, our hardwood floor cushion will soon flatten, and the computer chair can slide easily without obstruction. It may not be suitable for carpeted floors.
