I bought this one online over the lower priced mat in the store and it's a bit more sturdier. It's made for the Berber rug I have so that was a plus too. There's no lip around the edge so I don't trip on it. It does shift around about a 1/2" at times but that is not too much of a bother. The wheels do sink into the mat a bit and leave impressions but the mat bounces back nicely overnight. It has a smooth surface and cleans up easily. I'm happy with it for the price.
Always copy center ready to go no delays. The staff at the copy center are always ready to assist makes me kind of never wanting to buy a copying machine .
Very thin. Rolls up on the edges when weight is applied. Chair rollers leave grooves which makes the chair hard to roll. Edges are sharp and will cut you.
The product said it was for medium pile carpet. I am not so sure. My carpet is within the standards indicated for this product yet my chair (5 wheels) sinks through this product. I would not buy this one again.
