I bought this chair mat as a replacement for another that I had purchased from Staples. The prior mat lasted about two years. That's about all I expect out of this one. It needs to be a bit thicker as it develops indentations where the chair wheels tend to come to rest. This leads to the chair wheels rolling to the same spot and eventually cracking and failure of the mat.
This product is very good for the value placed on it. We have hardwood so we used some spongy cabinet liner on the bottom and it works great! Thank you.
Rollers on desk chair still sinking in when in same position foreven a short time. Just buy the heavy pad from the start or asheet of plywood to put under.
