I didn't realize when purchasing this mat that it is really intended to be very lightly used. It is too thin and fragile for my desk chair on rollers on my carpet! I should have purchased a much thicker more expensive mat! This one is useless for my situation! Live and learn!
I was not impressed at all of this protective carpet which is a thin plastic and the wheels of my chair sink into it . I am considering through it away very soon
The mat arrived rolled up tight and has refused to flatten out for multiple weeks. There have been weights on various areas of the mat the entire time without success. If you take a weight off of the edge and it appears to be almost flat it will be curled up again the next day. My only hope may be to wait for a hot sunny day and lay it outside in the sun for the entire day. The mat may be OK if it ever flattens out.
This carpet chair mat is of good quality for the money. It is a lower price point mat so it should be expected to be less substantial than others. It is a little thin and slightly bends over unevenness in the floor surface. Because of this the wheels on the chair will sort of stick between the anchoring cleats of the mat.
