I was very surprised at how well this online purchase went. Everything arrived super fast. So far the mat has exceeded my expectations in quality it's durability remains to be seen. Definitely recommend Staples as a great source for online shopping during this pandemic.
The mat is advertised for high pile carpet. It is really not up to the task. It is the same thickness as my previous mat but it does dent under my chair wheels. Dents are not bad but my previous mat was rock solid and never dented. This might be a material thing in that this mat is vinyl. I believe my previous mat was polycarbonate which is harder. I say that this is a good mat for the money because I priced commercial mats that for high pile and they are about twice the price. One brand was only about 50% more but the shipping was about the same as the mat price. The mat works and my chair does not get stuck in the dents. The dents seem to "heal" and not leave permanent dents. The mat does walk a bit on the carpet so every few days I have to reposition it. But this is a home office and not a home working office so not a big deal. Hence my title as good mat for the money and in my case for the intended purpose. If you are going to be on this mat 8 hours a day 5 days as week you'd be better served by buying a thicker commercial grade mat.
I bought the least expensive and so can't complain but it's so thin I already see impressions that won't ever come out and might begin in the not too distant future to crack.
