My husband got one of these a few months ago for his home office and recommended it when it came time to replace my home office chair mat. We have medium pile carpet and my old chair mat cracked and had chunks starting to fall out causing my chair to get caught. This one seems to be much sturdier yet flexible. It arrived flat so no waiting for it to uncurl.
MY husband decided he wanted a chair mat because I have been using one for a number of years and his chair is on a rug and just thought it would be easier for him to maneuver around. He loves it as I do too although mine is on a floor.
