I bought this to replace another Staples pad that I had for two years but had started cracking. While I thought I was buying the same thing it is not. This pad slides on carpet so I am not as pleased as I was with the other one.
This thing slides all over carpet like crazy. If you step on this mat without a chair on it you might very likely lose your balance and fall on the floor. Even with the chair on the mat it will still slide and is very annoying.
