Great idea, mats work very well for their intended use. My only complaint is that the adhesive backing is far too strong. I used the mats on 3 different sheet sets without an issue, then one night I placed it on a 4th sheet we have and by morning, when it came time to peel it off, the mat completely shredded leaving the glued sections stuck to the sheet... I spent time trying to peel it off, but it became a tangled mess and I ended up having to throw the sheet away. I thought maybe they were cheap sheets so i kept using the product anyways, again without issues, until today. This morning my son wet the bed and he wanted the responsibility of taking the mat off. At one point he placed the mat on the floor to get a garbage bag, He must have stepped on it on the way out because next thing I know he is yelling for me. I came into the room to see that the adhesive was stuck and embedded onto the carpet and wouldn't come up. I spent the next hour scraping bits of plastic, glue, and batting out of our brand new carpeting... this will be the last time we use the mats. It's really too bad the glue is so powerful, otherwise it's a great product.
