Review on 🛏️ Waterproof Zippered Mini Crib Mattress Protector Encases 6 Sides, Breathable & Absorbent – Ideal Playard Mattress Encasement & Pack N Play Mattress Cover by Jen Smith

I bought these so the child wouldn't try to take the mattress apart after taking the sheet off. This is for a mini crib (or pack and play) sized mattress - it will not fit in a standard crib. The cover is soft and has not (yet) been removed. When closed, the zipper flap is secured by a Velcro strap, which my son hasn't noticed yet, so he couldn't open the zipper. Washes well, easy to put on (we have a 3 inch mattress). It's definitely deep enough for a slightly deeper mattress (definitely 4 inches, 6 inches might do but be tight). The lower part is made of elastic material, which makes it easier to put on and take off. Haven't tested the waterproofing yet, but the sound isn't raspy like a lot of waterproof stuff. Overall I'm happy with it and it was just what I needed for our purposes.
