Abstract: The bed of the disclosure includes a foam overlay mattress (1) and a mattress support (2) in the shape of a ladder, releasably connected together by at least a strap (6) the ends of which are brought down around rods (3) of the mattress structure in order to be hooked, under the overlay mattress, to lugs (5) upwardly protruding from the mattress structure, such straps being provided with hooking rings (8) for that purpose. The mattress structure is completed by pairs of short feet (9).

Abstract: The play pen of the invention has a body including a peripheric frame formed of parallel side-members and extending between corner posts (4), each side-member including a rigid core which is covered by a flexible plastic tube extending beyond the core ends and fixed (at 9) to posts (4) in order to ensure a flexible connection between the latters and the various side-members. Each post advantageously includes a pair of damping elements (12) and (13) the floor (5) being floatingly fitted on the lower damping element 13.

Abstract: There is disclosed a water-and/or sandbox construction comprising an integrally moulded body having side walls and inclined upper edges, the bottom of which is formed with shaped protrusions or recesses for releasable engagement with complementarily shaped mounting portions of stackable levelling members having slots formed in their sides, which function as support members of selective height for supporting, depositing or storing members adjacent the top surface of the product contained within the box at a distance from the periphery of the box.

Abstract: The assembly comprises a structural member, for instance one made out of wood, surrounded by a sheath member made out of rigid or semi-rigid plastic material, the outer contour of said core member and the inner contour of said sheath member being established to provide space or play therebetween forming a damping cushion, said members being interconnected by zones of reduced area. In a typical embodiment, the inner core member has longitudinally extending grooves formed in the periphery thereof defining ribs therebetween the peripheral contour of which generally corresponds to the inner contour of the sheath member.

Abstract: The assembly and disassembly of such a bed is provided by a resilient clamping of the tips 7 of the side panels B and D on the posts 4 of the head and foot panels A and C, while said side panels and said head and foot panels form a dihedral greater than 90.degree.. The side panels are adjustable in height by means of a sliding movement of the tips 7 along the posts 4. The insertion of the mattress support S forbids any accidental disassembly of the bed.
