The same mat I bought before lasted almost 3 years. If the floor is not solid enough it ckacks. Also needs to be held in place with double tape because it moves.
I ordered this chair mat online and picked it up a few days later. I use it in my home office to protect my tile floor from the the affects of my rolling office chair. So far the mat done has done it's job of protecting my tile floor. The mat is about 1/8" thick has textured surfaces and it's pretty durable. The one thing I don't like about this mat is that it has sharp edges. The edges could be a hazard because a person could possibly cut their bare feet on them. Overall I recommend this mat.
