What a great crib mattress! I am very impressed with the quality! This is my 4th baby and by far the nicest mattress we’ve had. I love how one side is for infants and the other is for toddlers. You can press on each side and definitely feel the difference.... firmer on infant side and cushier on toddler side. Such a great transition piece that allows you to use for a much longer stretch of time as the child grows. I highly recommend!
