Breathable Waterproof Pack N Play Mattress Pad - 38.5" x 24" x 1.5" for Baby Mini Crib & Playard - Hypoallergenic & Machine Washable - Perfect for Travel, Daycare & Home Nursery Use

My baby would never sleep in his nuna sena aire no matter how much I tried. I spent a lot of money on it and I was disappointed that I couldn’t use it. I decided to buy this mattress. Guess what? He fell asleep in his Nuna Sena Aire for a first time ever. This fits just perfect!!Love itThis thing is amazing. We travel ALOT woth our 2 year old and he cannot stand sleeping in a pack n play. We use to always just put him in bed with us on trips. Amyhow we tried this and it made the pack n play so much more comfortable for him. Another nice thing is it has a zipper cover but we just out a pack n play fitted sheet on it and it works great with no slack. We use this as a mattress topper when we stay in hotels. It fits both in hotel cribs and in pack n plays. We have stayed at about 14 hotels in the past 2 months and it has worked im all of them. Then we just roll it up and pack it in our luggage. My photo shows how nicely it fits over hotel cribs for extra comfort (the fitted sheet we bought is gray)I’m happy with it! Most importantly, it doesn’t have crinkly waterproof covering that makes a noise whenever baby moves! So important. The cover is a plush soft cover. The mattress is not as think or as “memory-foam” like as I was expecting but it’s okay. It’s firm to keep baby flat and safe but not too firm that it’s uncomfortable. I can see a big difference in my baby’s sleep quality after just one sleep. Will review after more sleeps.This is amazing. Just what my 18 month old needed to travel and still feel like he was sleeping at home. This does not fold up well but we didn’t expect it to. We will be taking it with us for at least the next year when we travel so he has a little bit of home with him.This sits perfectly in a pack and play and is truly waterproof. We have washed the cover and there was no shrinking.Made the pack and play much more comfy for my daughter but it doesn't fit perfectly (has a gap along two sides) so I wouldn't recommend for someone with a very young infant as they could get wedged between the mattress and the walls of the pnp.Fit in my sons crib nicely! He slept in comfort instead of the hard pack and play mats.fits in a pack n play nicely (i have the cosco brand). i put a jersey fitted sheet over top, and placed it right on top of the cardboard mattress that it comes with. the babe slept wonderfully.
