Modular furniture system

A modular furniture system comprising:

• a stackable enclosure;
• an upper mattress support frame having vertically disposed side walls and first and second end walls;
• first end wall support means for supporting a first end of said upper mattress support frame;
• and
• means for interlocking inner surfaces of said side walls and said second end wall of said upper mattress support frame to the top of said stackable enclosure so that said upper mattress support frame is supported at said first end by said end wall support means and at a second end by said stackable enclosure.
• wherein said interlocking means for said upper mattress support frame second end and said stackable enclosure top comprises:
• side walls that extend downwardly from said upper mattress support frame more than said upper mattress support frame end walls, said side walls spaced apart to overlap and extend below said stackable enclosure front side and back side surfaces upper edges.

A modular furniture system comprising:

• a first and second rectangular enclosure, each having two sides and two ends of substantially equal dimensions;
• a rectangular mattress support frame having two side walls, two end walls and a top surface, the length of said side walls being substantially equal to the combined side surface length of said first and second enclosures when placed end to end and the width of said side walls being substantially equal to the end surface width of one of said enclosures;
• and
• means for interlocking said mattress support frame side wall and end wall inner surfaces to said enclosures when said mattress support frame is supported by the tops of said enclosures;
• wherein said interlocking means comprises side walls that extend downwardly from said mattress support frame more than said mattress support frame end walls, said side walls spaced apart to overlap and extend below said first and second enclosure side upper edges.

A modular furniture system comprising:

• a plurality of rectangular stacked enclosures having an uppermost enclosure, each of said enclosures having a front and a back side;
• a plurality of upwardly extending members, each having a first end attached to the inner surface of a lower enclosure and a second end extending upwardly into the volume enclosed by an upper enclosure, said upwardly extending members contacting the inner surfaces of said upper enclosure thereby interlocking said upper and lower enclosures when stacked one on top of the other;
• an upper mattress support frame having vertically disposed side walls and end walls, said side walls extending downwardly further than said side end walls and being spaced apart to overlap and extend below said uppermost enclosure front and back side upper edges;
• means for supporting a first end of said upper mattress support frame;
• and
• a crossbar attached to said uppermost enclosure front side and back side upper edges, said crossbar side surfaces extending upwardly therefrom and contacting the inner surface of said upper mattress support frame second end wall inner surface.

A modular furniture system comprising:

• a first and second rectangular enclosure, each having two sides and two ends of substantially equal dimensions;
• a rectangular mattress support frame having two side walls, two end walls, and a top surface, the length of said side walls being substantially equal to the combined side surface length of said first and second enclosures when placed end to end, and the width of said end walls being substantially equal to the end surface width of one of said enclosures, said side walls extending downwardly from said mattress support frame more than said mattress support frame end walls, said side walls being spaced apart to overlap and extend below said first and second enclosure side upper edges;
• a first crossbar attached to said first enclosure side upper edges, said crossbar side surfaces extending upwardly and contacting the inner surface of one of said mattress support frame end walls;
• and
• a second crossbar attached to said second enclosure side upper edges, said crossbar side surfaces extending upwardly and contacting the inner surface of the other of said mattress support frame end walls, whereby said mattress support frame is interlocked to said enclosures by said enclosure upper edges in contact with said mattress support frame side wall inner surfaces and said first and second crossbars in contact with said mattress support frame end walls.
