We've had other chair mats for our Berber carpets that have disintegrated over time. This one is significantly sturdier and we believe we'll get a longer "life" out of it.
The mat arrived promptly and I installed it. However it sinks into the very low pile carpet and isn't all that much easier to move the office chair on it.
the manufacturers sticker was easily removed with no residue the Staples delivery ticket was horrible and I had to razor blade it and remove with goo-gone
