I thought it would be thicker and more difficult for the castors on my chair to sink into the mat. I was disappointed that it wasn't any thicker than the one under my chair already.
After waiting for many delivery attempts I finally received my Carpet Chair Mat. It is so thin that I cannot roll my chair around on it. My chair "sinks" into the plastic and I have to stand up to push the chair around. Garbage!
Although I listed my carpet type on ordering the mat is too flexible and after a minute sitting in the same spot the mat has divots from the chair casters. It's too bad I didn't get a stiffer type of mat.
I thought this mat was a bit pricey but I wanted a good quality mat. The computer chair that is on this mat gets used daily. Between my husband and I my teenage children and grandchildren who visit every weekend it seems it is always being used. I had it for about 2 to 3 months and it’s just like new. Keeps my carpet from being ruined. I would recommend it. The only reason I gave it 4 stars instead of 5 is because it tends to slowly slip out from where I have it and I need to push it back in place about once a week.
