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
Honestly this mat is pretty terrible. The problem is that the material is too soft so after a few moments your chair’s casters will sink into divots that you’ll have to roll out of when you try to move (yes I’m a fairly normal size person; 6’1” 220)
I needed something to protect my carpet while I am temporarily working from home and this fits the bill. If I were going to work from home on an ongoing basis I would spend more to het a better one but this will do. It is already getting "Dimples" from the chair wheels but it is doing the job and the price was easily affordable. I would recommend it.
