How Do Convertible Cribs Work? The mattress’s consolation layer has a latex-foam hybrid top and a reminiscence foam base. This combination ends in a firmer, more supportive mattress that provides stress reduction and spinal alignment for a restful sleep. The baby crib options three adjustable mattress positions, and may be converted right into a toddler mattress, daybed, and full-size bed with a beautifully designed headboard and footboard. One of our most iconic and versatile Graco cribs, loved and trusted by tens of millions of families across North America. If you typically switch positions all through the night, you’ll want a mattress that’s supportive for all sleeping kinds.
