I bought this to replace a pad used on commercial carpet thinking it was as good as advertised. When it arrived it was exactly the same as one purchased locally for commercial grade carpet. I should have saved my money.
At first I thought it would be to big but the staff person loves how much wider this is. She rolls from her desk to a hutch that holds her computer. The first thing she said was it fits.
My fault for not measuring first but this is about 6" more narrow than the last one I had and that 6" makes a difference when swinging (or trying to swing) the chair around. Also mat is too soft and chair wheels sink in.
This mat is too thin for anything other than Commercial grade carpet. If you have any pile at all to your carpet. Better get a thicker more rigid mat. Sorry to say they cost more $.
This is a decent mat best used for hard surfaces or very thin carpet. The thickness is minimal & if you are of decent weight on moderately thick carpet your chair wheels will sink somewhat into the mat. I am able to slide around alot better than without it & it's better than nothing. A thicker mat is best for thicker carpet. Not sure how long it will last though. It's good for the price I paid though
