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.
