We figured adults sleep best on a good mattress so babies must too! Right? That's why we went with the Sealy Baby Ultra Rest mattress from Walmart. We loved that it has a great height at 6" and has inner springs to provide good support up to toddler age. So far baby loves the firmness of the mattress, we did however have to get a padded mattress protector to lessen the plastic - y sound of the waterproof mattress (more to come).

What do you look for in a crib mattress?
