the chair mat does a good job of protecting my carpet. But the clerk wrapped the plastic with tape and when I unwrapped it it will not lay completely flat.
This was to help roll my chair on carpet that made it otherwise impossible. This has minimized the effort but not nearly as much as it should. It is thin and the chair sinks into the plastic so it takes effort to push out of the grooves made when sitting in the same spot for a while. I'm not a heavy person so this is not ideal.
Does what it is supposed to do. Stays in place and doesn’t slide as the desk chair moves Around. Price was very reasonable. Would be willing to pay more for a mat that is a little more robust (thicker).
