I was hoping that if I spent a little more this chair mat would work after trying two others. WRONG. Too expensive for something that does not grip your rug. The mat itself proves to be durable but it does not grip into my medium pile Office rug. I have to adjust it 2-3 times a day as it continually slips out of place. I want to send it back.
I like the mat so far. It seems to be holding up well on a low pile carpet. Other mats have developed cracks so hope this more expensive one doesn't. I would recommend it.
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.
