The great thing about this is the price and I got my $10 worth. I would vote for a $15 version that is 8-12 inches longer. This one is a little too short and I find myself sliding off the mat. Also it sinks down into the carpet where the chair is. If the grippers on the bottom weren't so long I would use it in a different area on an oriental carpet atop a hard surface. That would be ideal.
OK for ordinary in home us for a small home office. DO NOT use on high pile carpet. Only use on low pile carpeting. Cheap flimsy construction. Chair forms pock marks and indentations in the chair mat itself. Lacks thickness and smooth rolling ability. Not worth the cost of item.
