I'm sorry we bought this. Hard to move chair around doesn't stay in place bunches up in same corner (no matter what angle you "glide" in). Supposedly the cleats hold it in place (ha!). Overpriced too for an item like this.
Very satisfied so far. More sturdy than my former mat. Only one concern the grips on bottom of mat to hold mat in place are much shorter that previous mat but has not been an issue so far. Perhaps it is a improved design. Would buy another at this point.
At first the chair moved effortlessly on mat but now after less than two weeks the castors make indentations on ithe supposedly "medium pile carpet" mat - much the mat this one was bought to replace.. The borders of the mat lay flat on the carpet . Overall it appears I should get a mat for high pile carpet although my carpet is low pile
