Great investment for quality baby sleep
Highly recommend this crib mattress! Comfortable for little one, breathable, and easy to change sheets on. It’s got a decent weight to it, so I feel assured my little one will have good support. No shrinkage with daily use so far.

Also good for cats
Added the crib sheets and before we could put it in the crib, it was already being tested. The baby also loved it. It’s firm but soft and thick. Seems like good quality thus far.

Seems decent but it looks like there are used items in circulation
Overall seems to be a good mattress. No odors, fits a standard crib and bedding nicely, no complaints from the kiddo. The only thing so far is it’s a bit of a lottery purchase. Fist one I ordered had a bent frame and packaging was definitely previously opened (didn’t have the guarantee tag either). Returned for another and the second arrived with a mark on it that makes me think it was previously opened as well.

Crib mattress
I bought this for my grandsons crib. It fit very well and was soft enough. Very light weight.

Quality
This is a good mattress. My one son who 2.5 has used this mattress since day one and it is still supportive and shows no wear on it. I actually repurchased this for my 3 year old, for his bed and he loves it. In 2.5 years it has not sunk in the middle like the other purchases for my 3 year old. Definitely worth the money.
