I was having problems with an old mat which had turned yellow and began to crack into pieces. The Economical Mat by Staples is the perfect replacement in my home computer room. It does just fine on the short pile rug. It doesn't creep or buckle and my chair glides across its surface very smoothly.
Iam 6'4" and 230lbs. need 4 to 6 more inch's in size. chair wheels sink's into pad and sometime's you have to get up to move need's to be thicker so chair can roll and not sink. thank's for listening. SNOWBIRD
