PiccoCasa Fitted Sheet Waterproof Bedding Sheet, Navy Blue Full

I was a little confused with the description of this item. I have owned mattress pads and covers for many, many years. And they are literally thick like padding- not thin like a fitted sheet. This, however, arrived as a sheet. Thin like a sheet. It fit my memory foam mattress well; deep, good pockets and the elastic is stretchy enough to fit the corners but tight enough to stay in place (see photo for very nice shot of the elastic banting). On the website description, it mentions a “TPU membrance back” backing, and I was worried it would be like plastic (and possibly noisy when sleeping on it or getting comfortable). I also noticed that the website description mentioned that this sheet is waterproof, but I have not yet tested that out (thankfully). I am sure it is water resistant it just feels like it would be a good barrier for liquid. And although it is LIKE a fitted sheet, my sheet sets are much softer (maybe a little more luxurious). So I was happy to simply put this under my regular fitted sheet and feel pretty confident that any spills would likely not make it to my mattress. And it is not “plastic- like” so it is comfortable under my regular fitted sheet.
