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.
