Chair mat seems like its made decently however its been weeks now and I still can't get it to be completely flat on the ground has humps in it from being rolled. I'd definitely pay more to get one that is stored/ shipped flat after this.
The chair mat fits the area perfectly. But when sitting in one place for longer than 5 minutes it get a temporary indentation - like a rut - that is hard to roll out of.
I bought the low pile carpet mat and it kept moving so I bought this medium pile carpet mat and it is doing the same thing. The teeth are about the same length so I don't see the difference in the low pile and the medium pile except the price
