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.
Only one drawback and that is where the packing slip was glued on to the top of the mat. 30 minutes to try and remove it and the glue. Still unable to remove the glue so shoes stick to the mat every time you touch the area where the glue was. Would not buy again only due to this sticker being on the top instead of the bottom of the mat.
