This is the best thing ever! You can carry it out of the store and lay it in your house without those pesky sharp points that used to cut your hands and legs. The bottom has little rectangle shapes that don't hurt you. Thank you Staples.
I have a desk chair with wheels that I don't want to damage the carpet in the room. This mat was the perfect size and covers all of the normal desk usage for a chair.
If I sit in my office chair for more than 5 minutes the wheels to the chair sink down into the plastic making it almost impossible to roll the chair. The carpeting in my office is quite low pile but not low enough for this.
