Review on BlueSnail Waterproof Portable Foldable Mattresses by Matt Mosley

I love these sheets for many reasons-1. tightness. I am very picky about how tight the sheets are for my child. I was concerned that this sheet would be too loose on the thin mattress/pillow that came with my backpack. As you can see in the picture this sheet fits perfectly, very tight! I was so happy. There is a tie at the back to keep the sheet as snug as possible. 2. Waterproof - My baby has had multiple spit, drool and diaper leaks on the sheets and they always protect the mattress perfectly. I've never had liquid flow through them.3. Durability - I've washed the sheets probably 10 times and they've held up great.4. Comfort - they are really soft and comfortable for my baby to sleep on. Overall, I really like these sheets!
