The plastic is very thin and does not give good support. The wheels on my chair sinks creating a low spot. This makes moving the chair very difficult. I weight about 200 lbs and that might cause some on my issues
It works okay on my berber carpet. My chair had already made indents into the carpet so with the mat on top my chair tends to roll to where the indents were.
I like that it is clear which keeps it looking fresh. Now having said that It is not thick enough to where my chair doesn’t sink in and get stuck but maybe that only happens if you are on a hard surface and not carpet and/ or you only weigh 175 lbs or less. I can say that I have had worse where it would sink in almost immediately but this one takes about an hour when sitting in one spot. Hope this helps.
