Set of two large potty training mats or pads by Pea pod mats. 100% cotton on the outside with a waterproof filling that is not crunchy at all. We used these for both of our sons and they work great! Best of all, they’re sustainable because they are machine washable and dryable. You never have to worry about them leaking on the sheets underneath, and both of our sons found them to be easy and comfy to sleep on. Large size, 36” by 56” covers a lot of the bed. Peapodmats.com
