I just moved into a new home/office and needed to set up a desk area with chair and chair mat. My new house has deep pile carpet and I knew that the office chair would destroy it and be difficult to manuver on. So I purchased this chair mat thinking it would solve my problems no such luck. The mat refuses to stay in place although it has tines on the back to grab the carpet. As I roll over it during the day it migrates its way under the desk where it bunches up in a big wave. I then must pull it back to its original location and stand on the wave to flatten it out. This happens at least three times a day. I am contemplating getting a different brand.
Not thrilled with this mat at all! I bought this mat because we needed a new one and thought I would go back to Staples where we got the first one. This one is different and doesn't stay in place very well. It has been re-designed from the last one we purchased from there. We did lay it out like it said to but it does not stay in place. It does not to seem to have a good grip on the carpet. I got this one because it was inexpensive and looked similar to what we did have. I am not satisfied with this mat and probably would not buy it again or buy one from staples again.
