This is an excellent mattress choice for the parent who wants the best. One side of the mattress is extra-firm to serve an infant's developmental needs, and the other side is a little softer for when your child gets a bit older. That alone is an excellent feature, but this model has an added bonus: the toddler side is cushioned with extra cushy memory foam. It's comfortable, well constructed, non-allergenic, and of highest quality -- with a 336-coil fabrication and super-durable cloth binding.
