Rather than going for a more expensive mat I went with this one. After about 3 days of work I have indentations where the chair sits most of the time. Now it seems to always gravitate to those indentations which eventually will probably go right through the plastic. Don't recommend.
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.
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.
