This mat is the same size as the one I had previously. However when I roll my chair off of the mat - the wheels gets caught on the end of the mat when I try to roll it back on. I exercise every morning and it becomes a challenge to lift my chair back onto the mat. I had purchased my previously mat from staples however it was a heavier/harder quality. On this mat I see the imprint of the wheels into the mat. I think the quality of the mat has been compromised.
The wheel movement of our office chair was begining to wear our carpet thin in several spots. The Staples Carpet Chair Mat solved that problem immediately.
