I love these mats, they have the extra piece so it is very hard for even my two daughters to bounce them off the bed. If and when one of them has an accident during the night with the Conni kids bed pad I can quickly take it off the bed change her clothes and have her back to sleep in no time at all. I recommend these to all of my friends, gives the kids confidence and a decrease in the washing for me and in the amount of time in calming them back to sleep after an accident.
