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!
Nice inexpensive mat for a home office. However seems to "dip" where the chair wheels even for a short period of time. But does the job for easily rolling the chair around over the carpet.
