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.
Having used this for almost a week I am still adjusting it. It tends to move and the more narrow end wants to curl up or not stay flat on the carpet. My chair does roll easily on its surface so that's a plus.
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.
I purchased this mat thinking it would be suitable for a high pile carpet but the chair wheels make an impression on the mat and I get stuck and cannot move unless I jerk the chair up out of the indentions. Would not buy this again.
