-It was extremely hard to unroll, -After a couple days it is still not flat,, -On both ends of the mat the finish is defective because It has little indentations all over it

Nice and large so it provides plenty of surface area for my office chair

Tip Immerse in tub of hot water before trying to unroll.

Extremely difficult to unroll and lay flat. Pulls at carpet and still not flat as oof week. Should be sent flat.

Mat is heavy duty and stays put. On the downside, the mat still get indentations from the chair casters due to the thickness of the carpet on which it has been placed. The indentations do disappear when the chair is not in use.
