This chairmat is used weekdays and holds up well for it's heavy use. It doesn't get noticed which is how this type of product should work! We always buy them again when they eventually wear out but it takes a long time!
Even on a flat pile office carpet this mat was too soft. Dents would form where my chair had sat even if I wasn't sitting in it at the time. I chose to exchange this for a firmer better quality and slightly larger version.
