Nice and thick to protect my wood floors. Has great shock absorption for my treadmill. Only issue is the mat curls up when the treadmill inclines instead of it rolling on it.
Sears/Kmart continually have sent the wrong items that I have purchased. Usually they are fairly close to the same items. This time the items weren't even close. I received tennis rackets instead of the puzzle mats. Done with purchasing anthing from these companies. no wonder they are going out of business.
