I bought this mat as a replacement and it works excellently. The previous mat lasted me 5 years but was cracking in the center because it was a folding chair mat-- the center seam finally was breaking away. This mat was a great value for the money and I highly recommend it.
It's exactly what I needed so my chair could move easily on a carpeted floor. [...] It is a replacement for another chairmat that I got from Staples over 14 years ago! Very satisfied!
I use the mat to protect the carpet from the wheels on the chair I use at the computer. The wheels sink into the mat making an indentation preventing them from rolling freely. The mat should be made with a thicker and harder material as they had at an office where I once worked and had carpeted floors such as mine.
