It was exactly the right size. I have always purchased the chair mats with the cut-out section for the chair opening of the desk This time I bought the solid 36 x 48 rectangular mat and it works so much better. No slipping and moving...and my chair rolls easily over the mat. I have thick carpet under my desk and this mat stays put. Also I ordered late one evening and it was delivered on the second day after ordering. Very speedy delivery. Thanks!
My office chair sank into the soft plastic and couldn’t roll freely. Why it’s marketed as being for “Extra Carpet” is beyond me; I can’t imagine it working on anything but hard floors Returned it the next day and Staples took it back without any hassle.
