I registered for the Sealy Soybean Everedge mattress - http://www.toysrus.com/product/index.jsp?productId=11306119
We didn't receive it at our shower, so I am just going to purchase a mattress now.
But I'm thinking of getting another less expensive one instead like the Sealy Firm Rest - http://www.toysrus.com/product/index.jsp?productId=11459691. It's $40 bucks cheaper and seems fine.
What crib mattress did you/do you have and do you like it?
