My wife and I love it! Our newborn sleeps soundly on it.

Pros: Fits perfectly in the crib.
Cons: If you use a mattress protector with a sheet, it may be to tight.

As other have stated - the smell of this mattress is potent. Having read the other posts, I washed the mattress in soapy water and allowed it to air out for two weeks prior to using. I can't imagine using the mattress without doing that.

Although the mattress is constructed well, it isn't the most comfortable for a little one. Because of this, we purchased an additional pad for the top of the mattress to make it slightly better to sleep on. I recommend doing the same, if you decide to purchase this.

The mattress was a decent value, but I find it peculiar that it had such a strong smell. Being a mattress for children should subject it to some different standards in terms of the grade of plastic used in the manufacturing process. Smells aside, this mattress turned out to be a decent purchase.

My son loves this mattress. We had a cheaper mattress that come with the crib we ordered and it was so bouncy. I would pat my son on the back to help him go to sleep and the whole mattress would bounce. I decided he needed a new mattress and settled on the Sealy Baby Posturepedic Crib Mattress. It is nice and thick. You can tell there are a ton of coils in it and I can even feel the corner and edge support. Best of all it isn't bouncy and my son is once again sleeping like a baby!

Best mattress

from OK on 10/27/2015 – Verified Buyer

We love this mattress because it is has the staff guard and its firm but not too firm. It also has a lot more layers than other mattresses and more coils which makes it firm enough to hold up a toddler and not sag on the edges. We are planning to use it for more than just one child. It's very well made.

This mattress was a great deal, the price is amazing for the quality of mattress. I looked at other stores for mattresses and they were $200+ for the same kind of mattress, can't wait to see my baby in it. Would recommend as an alternative to these high priced stores.

Good product

from CA on 11/30/2015 – Verified Buyer

A little on the firm side which is needed for babies but will eventually change to a softer mattress when older.

My baby has a better mattress than me! I'll have to admit that when w got it, I laid on it briefly and was only asserted that I made a good choice. You can never go wrong with Sealy!
