Abstract: A convertible crib and bed system for converting a bed into a crib. The convertible crib and bed system includes a first partition that is attachable to a first wall, a first leg member attached to the first partition, a second leg member attached to a second wall, a pair of receiver channels within the leg members, and a second partition that is slidably received within the receiver channels. The first partition includes a support member that is secured to the wall via fasteners. The second leg member is secured to the wall also with fasteners. An adjustment structure at the base of the leg members allows for adjustment of the vertical height of the leg members. The bed is positioned beneath the first partition against the walls thereby forming a crib structure. Removing the partitions returns the bed to normal usage.
