Infants need an extra-firm mattress and toddlers need one that's a little softer. So how do you pick? Now you don't have to, with this innovative, high-quality mattress. The two sides are cushioned to meet these two developmental needs, so that you never have to compromise. When your child gets a little older, just flip the mattress over. It's both comfortable and well constructed, with a 135-coil fabrication and triple-laminate vinyl cover.
