I purchased the Ergo comfort rug for my kitchen and thought it would be great.  However, I could not keep the rug from moving around the cushioned mat and the mat wouldn't stay put on the floor even though I had four sticky discs at each corner to hold it in place. I was literally having to move the rug and mat every few days to get it back where I wanted it. It's too bad because I really thought I had purchased the best of both worlds...a comfortable gel mat with a washable rug on top. If the company can come up with a better "system" of keeping the mats in place, I would be willing to give them another try.
