Does what is suppose to do. Protects the rug. Chair doesn’t roll easily on it. I have a low pile rug which was suppose to be what this was design for. The plastic is a little to soft.
On line ordering process went easy. Price was good. Shipping time & handling charge reasonable. Arrived via UPS. Not boxed. Somewhat warped on back edge. Placed on my patio in the direct sun for a day. That eliminated the warped areas. The thickness of this mat is perfect for my carpet that has maybe 1/2" knap. The nubbies on the bottom of the mat keep it from moving around. Office chair rolls easily.
The size is great. It is not the easiest for the chair to roll around on. It leaves dents where the wheels set. I have to push a little to get the chair to move.
