Nice and wide (used long ways right to left). Fits my office space well and I do not roll off any side of the mat. Due to size hard to carry when delivered. Wish it had handle cut outs like my previous mat.
I put it down the day I received it. In no time were there divots. I have to move the chair every so often so I'm not stuck in them. It is a great size for the home office but it should be thicker.
