I was looking for a mat for my hardwood floor and the prices vary so much. I chose this one and it works just fine. I don't really see a need to spend twice the money for something so simple in design.
My "office" chair would bog down on the carpet. I do a great deal of my day getting up & down and because the chair was hard to move it made it agravating. NOW with the MAT my chair slides like a hockey-puck on ice.
