Met my needs perfectly. Compact in size it works for my small room and is big enough to cover a worn spot on the carpet underneath plus my desk chair moves easily on it.
This is the second one that I have purchased over the years. My hardwood floors are getting old and I am using these to stop any future damage from our office chairs. They work great and last a very long time. My first one was purchased over 10 years ago and still looks brand new.
I'm puzzled that the reviews aren't better on this. We bought two of these one being used with a Staples Sorina Chair and the other with a Herman Miller Aeron with standard casters both on short (3/8-1/2") carpeting. Both are being used by pretty lightweight (under 125 pounds) people and maybe that explains it. Or maybe some of the reviews aren't correctly attributed? After being dissatisfied with some really cheap mats I made a point of getting the thickest and stiffest material in the rack at Staples. These mats have been great. We will probably get a third one for my office.
