  • Perfect mattress for mini crib!
Size: 38x24x4 Inch (Pack of 1) Style: Mattress
We bought this for my daughter for her mini crib, we were a bit tight on space in our apartment and had to purchase something smaller. Overall it’s a great product for the price, it doesn’t make any noise when putting down the baby, it’s soft and has great support. We also use this whenever we need to go on trips because it fits perfectly into our pack and play, it’s quite durable! It has many uses, happy we purchased it. ... show more

  • Great quality and safe!
Size: 38x24x4 Inch (Pack of 1) Style: Mattress
This fit great with the mini crib we chose, and the quality is great in the sense that it does not “feel” cheaply made and it is firm to use for newborn baby and even up until now (she is 2 years old now). It is also easy to clean after accidents, and easy to put on/off mini crib size sheets. Great mattress overall! ... show more

  • Safe and comfortable
Size: 38x24x4 Inch (Pack of 1) Style: Mattress
I didn’t want a thin matress for my baby I love that it is wipe down for those days they are sick it makes it so much easier you just get a new sheet and a Clorox wipe and your ready to go it fit my mini crib perfectly it’s not crinkly sounding like most and she doesn’t sweat a lot on it (she sleeps hot) the only thing I could think about is if your little one gets out of the crib easily maybe go for something thinnner because she does get out of her crib due to the height of the matress ... show more
