Just as advertised. The size was just right for our small office. Did not experience the curling problem another reviewer had. Only con so far is the label on the mat did not come off easily - leaving a sticky residue behind. The mat looks like cracked glass and while it does allow the floor to show through rather well don't expect it to be crystal clear.
I have hard wood floor and use the mat at my computer desk. The only complaint I have is the mat is not big enough and the chair always rolls off the mat. End up buying another larger mat and put this one at my son's desk where he does not have a rolling chair.
Because my carpeting is thicker than recommended for mat's thickness the ends tend to come up. With use on low-pile commercial grade carpeting I believe this mat would be adequate. Chair still rolls well and mat is easy to clean.
