VERY disappointed with this mat. It's light-weight does not stay in place chair canisters become stuck in the many divots can trip because does not remain flat etc. etc!! Have since researched and purchasing hopefully a much better quality mat. DEFINITELY WOULD NOT RECOMMEND.
I've had the mat for less than a week and already it shows dents from chair's roller wheels. Disappointed in "thin" quality. Replaced previous desk mat from Stapes that lasted for several years. A shame they downgraded the quality -- and the size.
It is working fairly well except I wish I had gotten a thicker one. My carpet is short pile. If I sit for an hour my chair is in shallow indents that I have to push to get out of.
does show chair wheel indentations but does not yet seem to hinder chair rolling easy to roll back on to mat if you roll off. generally pretty satisfied. would recommend.
