Chairmat is way too thin. A chair makes depressions & your stuck & can't roll. Eventually the depressions will disappear. I am only glad I was able to buy two these mats while they were half price. I wouldn' buy another one though.
Purchased item to place under desks to save the carpet from all the mess from workers shoes. So far it's doing a good job. Only drawback I see with these is that they tend to be a little fragile/break more easily than I like. Didn't purchase in stores because of that (and they didn't have enough stock). 1 out of the 9 we bought were broken so that's not bad; I would just like to see them not broken before they're even used.
The chairmat seems nice. Too bad Staples ruined by sticking their shipping labels right on it... after trying to dissolve the label adhesive for over an hour I gave up and called and complained. Now I have to wait another two days to get another one. Wanna bet the next one comes in the same condition?
