My daughter loves this mattress. She can sleep for several hours even turning over in her sleep she does not wake up. And when she wakes up's see wakes up with a big smile. The mattress is comfortable yet firm enough and she does not sink in whether she's laying down or up on her hands looking about. It has no offending smell right out-of-the-box whatsoever and is very quiet. I would recommend this mattress to anyone with all of its wonderful features is the perfect mattress for our baby and yours.
