Colgate Classica III Foam crib mattress, practically new (we got it when my daughter was around 6 months because we were worried that the previous mattress we had was too soft). She used it for a couple of weeks before she found a permanent spot in our bed. We always have waterproof mattress protector and crib sheet on. $120

Same as this one,
