Abstract

A combination chair/bed furniture and method of using. The furniture includes a support frame system and a multi-fold cushion assembly adapted to be supported by a frame of the support frame system. The cushion assembly includes folded cushions that define a seat cushion supported by the frame in a chair configuration of the furniture and when extended defines a mattress supported by the frame and at least one mattress support frame of the support frame system in a bed configuration of the furniture. A seat back is supported by the frame in the chair configuration of the furniture and serves as a headboard or additional mattress in the bed configuration.

First claim

The invention claimed is:

1. A combination chair/bed furniture comprising:
a support frame system comprising a frame and at least one mattress support frame;
a multi-fold cushion assembly adapted to be received on and supported by the frame, the multi-fold cushion assembly comprising first, second, and third cushions that when folded define a seat cushion supported by the frame in a chair configuration of the furniture and when extended define a mattress supported by the frame and the at least one mattress support frame in a bed configuration of the furniture, the first cushion being a lower cushion of the seat cushion and supported by the frame in the chair configuration of the furniture, the first cushion defining a head portion of the mattress supported by the frame in the bed configuration of the furniture, the second and third cushions being intermediate and upper cushions supported by the first cushion and the frame in the chair configuration of the furniture, the second and third cushions being extendable from the first cushion to define midsection and foot portions of the mattress supported by the at least one mattress support frame in the bed configuration of the furniture; and
a seat back comprising a flexible cushion received on and supported by the frame in the chair configuration of the furniture and adaptable to serve as either one of a headboard and an additional mattress in the bed configuration;
wherein the flexible cushion of the seat back surrounds and borders an outer periphery of the multi-fold cushion on three sides thereof in the chair configuration of the furniture.

2. The combination chair/bed furniture of claim 1 , wherein the at least one mattress support frame comprises first and second mattress support frames stored within the second and third cushions, respectively, while the first, second, and third cushions are folded to define the seat cushion.

3. The combination chair/bed furniture of claim 1 , wherein a side of the seat back rests directly on the frame in the chair configuration of the furniture.

4. The combination chair/bed furniture of claim 1 , wherein the seat back is supported by oppositely-disposed retention members of the frame in the chair configuration of the furniture.

5. The combination chair/bed furniture of claim 1 , wherein the seat back when adapted to serve as the additional mattress is extendable and receivable on the first, second, and third cushions to serve as the additional mattress in the bed configuration of the furniture.

6. The combination chair/bed furniture of claim 1 , wherein the frame and the at least one mattress support frame are each laterally expandable to increase lateral widths thereof in the bed configuration of the furniture so as to accommodate and support the mattress and the seat back when adapted to serve as the additional mattress in a side-by-side arrangement.

7. The combination chair/bed furniture of claim 6 , wherein the frame and the at least one mattress support frame each include a plurality of interdigitated cross members each configured to slide laterally relative to adjacent ones of the cross members.

8. The combination chair/bed furniture of claim 1 , wherein the at least one mattress support frame is coupled to one of the second and third cushions.

9. The combination chair/bed furniture of claim 1 , wherein the at least one mattress support frame is not coupled to the second cushion or third cushion.

10. A combination chair/bed furniture comprising:
a support frame system comprising a frame and at least one mattress support frame;
a multi-fold cushion assembly adapted to be received on and supported by the frame, the multi-fold cushion assembly comprising first, second, and third cushions that when folded define a seat cushion supported by the frame in a chair configuration of the furniture and when extended define a mattress supported by the frame and the at least one mattress support frame in a bed configuration of the furniture, the first cushion being a lower cushion of the seat cushion and supported by the frame in the chair configuration of the furniture, the first cushion being supported by the frame and defining a head portion of the mattress in the bed configuration of the furniture, the second and third cushions being intermediate and upper cushions supported by the first cushion and the frame in the chair configuration of the furniture, the second and third cushions being extendable from the first cushion to define midsection and foot portions of the mattress supported by the at least one mattress support frame in the bed configuration of the furniture; and
a seat back comprising a flexible cushion received on and supported by the frame in the chair configuration of the furniture with the flexible cushion of the seat back surrounding and bordering an outer periphery of the multi-fold cushion on three sides thereof and longitudinal ends of the seat back located between oppositely-disposed retention members of the frame and lateral sides of the multi-fold cushion, the seat back being extendable and receivable on the first, second, and third cushions to serve as an additional mattress in the bed configuration of the furniture;
wherein the frame and the at least one mattress support frame are each laterally expandable to increase lateral widths thereof in the bed configuration of the furniture so as to accommodate and support the mattress and the additional mattress in a side-by-side arrangement.

11. The combination chair/bed furniture of claim 10 , wherein the frame and the at least one mattress support frame each include a plurality of interdigitated cross members each configured to slide laterally relative to adjacent ones of the cross members.
