The mattress has an infant side which is nice and firm and a softer side for toddlers. I weigh about 135lbs and it supported my weight so i have no doubt we’ll be using this mattress for years as he grows into toddlerhood. The toddler side is softer.

It fits snugly in a standard crib. It fits our pottery barn kendall crib perfectly. Fits perfectly in our ikea crib.

This does the trick! Mine is just right! Worth spending a little extra money for this mattress. And it turns out i actually love it.

This is advertised as firm, this mattress seems way too soft. The waterproof cover balloons up and stays puffed up even after attempting to get the air out. It also makes a crinkly noise.

The infant side is too soft and balloons like an air mattress does, even under the weight of my tiny six pound infant. The dent is huge and it makes me uncomfortable because i feel like it's unsafe to have her use it anymore.
