Bests & Worsts Reviews from Amazon

This was absolutely the worst value I have ever received for a $30+ investment. It is definitely far inferior to any other product of its type I've ever seen. Not only is the surface so soft that my chair leaves a deep and permanent indentation wherever my chair wheels happen to come to rest. I have to literally shove my chair to get it out of the ruts. In addition, in spite of its having a studded bottom surface, it somehow manages to slide around on my carpet, probably because the darn thing never really lays flat on the carpet; there are always curls and "bubbles" in it. Amazon showed it with a $70 "list price". Talk about a bait and switch! Buyer beware! I found far better values at Office Depot.
