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.
A 200lb weight on a 5-wheeled office chair is too much for this mat. It does protect the carpet from the deep wheel marks; however the chair wheels create depressions in the mat. Hindsight tells me I should have opted for the heavy pile carpet (I am currently working on ~3/8" pile carpet)
This mat is my second desk chair mat in about 6 0r 7 years! That's how long the last one served it's purpose in protecting my carpeting from the daily use of my desk chair rolling back and forth on it.
