I needed a chair mat and bought the cheapest one the store had. Cheap is not always good. This mat is on a low nap rug but sinks into it making a bumpy ride when I try to roll my chair. Should have spent a little more money for a sturdier mat!
They are perfect - just what we were looking for. They flattened out easily - after using them for a day they are right where they need to be. Thanks. :)
