Portable lightweight bed

1. A lightweight bed assembly kit comprising: a plurality of slats;

a plurality of runners, the slats and runners being adapted for connection to each other at spaced apart locations to form a grid;

at least one U-shaped channel member adapted for receiving a portion of the grid and connecting to the grid to form a support frame; and

a covering distinct from said U-shaped channel member and sized and shaped to be disposed on a top surface of the support frame and constructed to form a substantially smooth sleeping surface for a human.

2. The lightweight bed assembly kit of claim 1 , wherein the slats, the runners, the channel member, and the covering are all made of the same material.

3. The lightweight bed assembly kit of claim 2 , wherein the slats, the runners, the channel member, and the covering are made of plastic corrugated board.

4. The lightweight bed assembly kit of claim 1 , wherein the kit further comprises a second support frame, the second support frame comprising a plurality of slats, a plurality of runners, the slats and runners being adapted for connection to each other at spaced apart locations to form a grid, and at least one U-shaped channel member adapted for connection to the grid.

5. The lightweight bed assembly kit of claim 4 , wherein the assembly kit weighs no more than about 35 pounds.

6. The lightweight bed assembly kit of claim 4 , wherein the at least one U-shaped channel member is adapted to connect the support frame to the second support frame.

7. The lightweight bed assembly kit of claim 4 , wherein the covering is a unitary covering sized and shaped to simultaneously cover both the support frame and the second support frame.

8. The lightweight bed assembly kit of claim 1 , wherein the covering is mounted on the support frame with at least one screw.

9. The lightweight bed assembly kit of claim 1 , wherein the covering is a unitary covering made of plastic corrugated board that is heat sealed at spaced intervals.

10. The lightweight bed assembly kit of claim 1 , wherein the covering comprises a plurality of surface channels adapted to improve air circulation over the substantially smooth sleeping surface.

11. The lightweight bed assembly kit of claim 1 , wherein the covering is adapted to be folded for easy disassembly.

12. The lightweight bed assembly kit of claim 1 , wherein the runners further comprise engaging slots at spaced intervals along a length of the runner.

13. The lightweight bed assembly kit of claim 12 , wherein the slats further comprise engaging slots at spaced intervals along a length of the slat, the engaging slots of the slats being adapted to engage the engaging slots of the runners.

14. The lightweight bed assembly kit of claim 1 , wherein the support frame comprises ten runners.

15. The lightweight bed assembly kit of claim 14 , wherein the support frame further comprises twenty-four slats.

16. A lightweight bed assembly kit comprising: a plurality of slats;

a plurality of runners, the slats and runners being adapted for connection to each other at spaced apart locations to form a grid;

a sheet of corrugated material adapted to be disposed on an upper surface of the grid as a planar covering, the planar covering being constructed to form a substantially smooth sleeping surface; and

surface channels located on the substantially smooth sleeping surface to allow air circulation over the sleeping surface, the surface channels including first channels extending in a first direction and second channels extending in a second direction transverse to the first direction.

17. The lightweight bed assembly kit of claim 16 , wherein the surface channels located on the substantially smooth sleeping surface comprise:

heat-sealed channels having a depth and extending in a direction transverse to a direction of corrugation of the corrugated material; and

extruded channels having a depth and extending in a direction parallel to the direction of corrugation of the corrugated material, wherein the depth of the extruded channels is less than the depth of the heat sealed channels.

18. The lightweight bed assembly kit of claim 16 , wherein the planar covering is adapted to be one of rolled and folded for storage or transport.

19. A method of assembling a lightweight bed, the method comprising: arranging a plurality of runners and a plurality of slats generally transversely to each other and connecting the runners and slats together to form a grid including spaced apart slats and runners;

connecting at least one U-shaped channel member to the grid to form a support frame, said connecting comprises said at least one U-shaped channel member receiving a portion of the grid;

and

mounting a covering separate from said U-shaped channel member on a top surface of the support frame, wherein the covering is constructed to form a substantially smooth sleeping surface.

20. The method of claim 19 further comprising connecting a second support frame to the support frame, wherein the second support frame comprises a plurality of runners and a plurality of slats arranged generally transversely to each other and connected together to form a grid including spaced apart slats and runners and at least one U-shaped channel member connected to the grid.

21. The method of claim 19 further comprising attaching the covering to the top surface of the support frame with at least one screw.
