I like the way it covers the carpet and makes it so my chair can move. However it does sort of dent in and the chair sticks in the dents if you’ve been sitting in it for a while. I think that is just the nature of the beast. This was the thickest mat I could find.
the mat indents under the wheels when sitting on it. The mat is supposed to be for slightly higher carpet levels - I had assumed that it would be firmer and not make "sink-holes" under the wheels. I would suggest finding a harder mat.
I liked the cost of this item but it doesn't go well with any type of thicker carpet. The plastic is not stiff enough and it forms divots that your chair gets stuck in. Would not recommend.
