a floor-supported furniture base, and

a plurality of frame sections supported on the base,

the frame sections including a first seat section rigidly fixed to the base in a generally horizontal orientation, a second seat section having one side pivotally connected directly to a forward side of the first seat section without intervening frame structure therebetween, and a seat back section pivotally connected to an opposite side of the second seat section,

the frame sections being movable between the folded seating condition wherein the second seat section is pivoted into overlying direct superposed face abutment to the first seat section and the seat back section extends angularly upwardly from the second seat section for use as a seat, and the unfolded sleeping condition wherein the second seat section and the seat back section are aligned horizontally with the first seat section for use as a bed.

2. A folding furniture structure according to claim 1 , wherein the base comprises spaced opposing arm sections, the first seat section being affixed between the arm sections.

3. A folding furniture structure according to claim 1 , further comprising furniture cushions supported on the second seat section and the seat back section in the folded seating condition.

4. A folding furniture structure according to claim 1 , further comprising a storage space within the base beneath the first seat section.

5. A folding furniture structure according to claim 1 , further comprising an air mattress inflatable into a mattress configuration conforming to the dimensions of the frame sections in the unfolded sleeping condition and deflatable into a configuration conformable to be folded within the frame sections in the folded seating condition.

6. A folding furniture structure according to claim 1 , further comprising a leg attached to the seat back section for movement between an operative position depending from the seat back section into floor contact in the unfolded sleeping condition for supporting the frame sections and a inoperative position nested with the seat back section in the folded seating condition.

7. A folding furniture structure according to claim 1 , further comprising a positioning stop element fixed relative to the base for abutment therewith of the seat back section in the folded seating condition for positioning of the seat back section relative to the first and second seat sections.

8. A folding furniture structure for converting between a folded seating condition suitable for use as a seat and an unfolded sleeping condition suitable for use as a bed, the furniture structure comprising:

a floor-supported furniture base, and

a plurality of frame sections supported on the base,

the frame sections including a first seat section, a second seat section, and a seat back section pivotally connected in end-to-end relation,

each of the first seat section, the second seat section, and the seat back section having a respective rearward side and a respective forward side,

the forward side of the first seat section being pivoted directly to the rearward side of the second seat section without intervening frame structure therebetween and the forward side of the second seat section being pivoted to the rearward side of the seat back section,

the first seat section being rigidly fixed to the base in a generally horizontal seating orientation with the respective rearward side of the first seat section oriented rearwardly relative to the base and with the respective forward side of the first seat section oriented forwardly relative to the base,

the second seat section being movable pivotably relative to the first seat section between a first generally horizontal disposition in the folded seating condition wherein the second seat section overlies the first seat section in superposed direct facing abutment therewith the respective forward side of the second seat section oriented to face substantially rearwardly of the base and a second generally horizontal disposition in the unfolded sleeping condition wherein the second seat section extends forwardly of the first seat section in substantially horizontal alignment therewith, and

the seat back section being movable pivotably relative to the second seat section and translationally relative to the first seat section between a generally upright disposition in the folded seating condition wherein the seat back section is disposed rearwardly relative to the base in generally upright angular relation to each of the first and second seat sections and a generally horizontal disposition in the unfolded sleeping condition wherein the seat back section extends forwardly of the second seat section in substantially horizontal alignment with each of the first and second seat sections.

9. A folding furniture structure according to claim 8 , wherein the base comprises spaced opposing arm sections, the first seat section being affixed between the arm sections.

10. A folding furniture structure according to claim 8 , further comprising furniture cushions supported on the second seat section and the seat back section in the folded seating condition.

11. A folding furniture structure according to claim 8 , further comprising a storage space within the base beneath the first seat section.

12. A folding furniture structure according to claim 11 , further comprising an air mattress inflatable into a mattress configuration conforming to the dimensions of the frame sections in the unfolded sleeping condition and deflatable into a configuration conformable to be folded within the frame sections in the folded seating condition.

13. A folding furniture structure according to claim 8 , further comprising a leg attached to the seat back section for movement between an operative position depending from the seat back section into floor contact in the unfolded sleeping condition for supporting the frame sections and an inoperative position nested within the seat back section in the folded seating condition.

14. A folding furniture structure according to claim 8 , further comprising a positioning stop element fixed relative to the base for abutment therewith of the seat back section in the folded seating condition for positioning of the seat back section relative to the first and second seat sections.
