The mat doesn't work well at all. I have a low pile commercial carpet and the plastic is so thin that the wheels have formed a rut in the mat. SO I doesn't allow me to move the chair around.
the product is supposed to remain in place on a plush carpet. it does not! i paid almost twice as much for this expecting that the little "grippers" on the bottom of the mat would be longer than the non-plush version. that is not the case so i am still constantly putting it back in place. not worth the money.
The mat wasn’t in a box and had been warmed in the delivery truck so it was pliable and laid flat right from the start. It works great keeping the chair casters from ruining our new laminate flooring.
