Review on ⛑️ Waterproof Pack N Play Mattress Cover 27" X 39" - Fits Most Playards, Foldable Mattresses and Pack and Plays - Fitted, Comfortable and Soft Mini Crib Mattress Protector by Little One's by Julie Lee

We have had this mattress topper for over a year now and it is still in great condition! I originally bought this protector because some reviewers mentioned it was quiet and decided that one day we would need a waterproof case to protect it from spills. I'm so glad I bought it earlier! I had forgotten how noisy our backpacks and play mattress are until we recently traveled without protectors. Every time my daughter moved or walked on the mattress you could hear it so please note that you cannot leave the house with a mattress and you cannot take this protector with you. no liquid has penetrated. Definitely recommend this protector! Love to know it's not flame retardant treated.
