The crib of claim 9, wherein each of said end walls further includes at least two horizontally spaced apart downwardly extending engagement slots and said side wall includes at least two upwardly extending engagement slots, each of said engagement slots located in a region adjacent to a lateral extremity of said side wall, and each of said upwardly extending engagement slots of said side wall mates with a corresponding said downwardly extending engagement slot in each of said end walls thereby interconnecting said side wall with said two end walls.11. The crib of claim 9, wherein said at least one wall assembly is implemented as two wall assemblies, and each of said wall assemblies is further configured with a preformed reinforcement rib fold line such that folding said wall assembly along said preformed reinforcement rib fold line forms a reinforcement rib projecting downwardly along an edge said support element.12. The crib of claim 9, wherein said bridging element is configured such that each end is folded so as to form attachment flaps to facilitate attachment to said end walls.13. The crib of claim 12, wherein said longitudinal slot extends into said attachment flaps so as to form stabilizing slots adjacent to surfaces of each of said end wall, said stabilizing slots accepting terminal edges of said reinforcement rib.14. The crib of claim 9, wherein said bridging element is configured with at least one preformed lateral fold line such that folding said bridging element along said preformed lateral fold line render said base system in a compact storage state.15.
