The staff person in the chair that's on this mat rolls from desk to file cabinet on the right and to the printer on her left; she needs coverage and this mat is wide enough to do it.
We've had the chairmat about two weeks. It is on berber carpet and has worked fine. We've had a couple of small indentations from the chair wheels but haven't had any problem rolling the chair.
Was a little thinner than I expected. The last one I had was thicker and bigger but that one was purchased about 10 yrs ago. So if this one lasts 5-7 yrs I would be happy! Good deal for the price. I was able to carry it right out of the store.
I bought this to help my aching knees from constantly trying to push myself around on carpet and it doesn't appear that it will help much. Rolling around on it takes almost as much effort as it does on the thin carpeting we have. It arrived in a roll and when trying to remove the tape holding it together it left behind a lot of the gum - so now my feet stick to it. Definitely not happy with it.
