Chairmat works best on short pile and berber carpets. Mat is too soft to use on plush carpets...it will bend and crack in a few weeks or few months depending on the amount of weight that's on the mat.
It looks ok. It dipples under the chair. I only weigh 140 lbs and once I sit down on my chair it makes an indent in the surface of the mat. Which inturn does not allow the chair to roll easily over the surface of the mat. I will be ordering new mats soon. Big dissapointment.
