Placoot 48" x 36" Heavy Duty Clear Office Chair Mat for Hardwood Floors & Carpet - Crystal Clear Desk Chair Protector for Hardwood, Tile & Carpeted Floors - Perfect for Home Office, Gaming Setup & Workspace

This is a flimsy piece of plastic that dents under my office chair rollers, the 3 fold creases are also very prevalent and my rollers roll into them.It also doesn't sit flat because it's so flimsy, so with my chair on it the edges stick up.I'm using this on carpet but it was advertised that it worked for carpets when clearly it doesn't.
