A sofa bed comprising:
- a pair of armrests;
- at least one first seat cushion disposed between the pair of armrests;
- at least one first connector attached to each of the at least one first seat cushion;
- at least one second seat cushion disposed between the pair of armrests;
- at least one second connector attached to each of the at least one second seat cushion, wherein the at least one first connector and the at least one second connector form a hinge joint;
- at least one third seat cushion disposed between the set of armrests;
- a first seat base attached to the at least one first seat cushion;
- a pair of stand bars supporting the first seat base;
- a second seat base attached to the at least one second seat cushion;
- a third seat base attached to the at least one third seat cushion, wherein the second seat base and the third seat base are connected in a hinge joint;
- at least one rotating shaft disposed in one of the armrests, wherein the third seat base is attached to the rotating shaft opposite the hinge joint with the second seat base;
- a pair of support legs configured to support the first seat base;
- a pair of first slide rails, each attached to one of the pair of support legs;
- a pair of first glide wheels, each connected to one of the first connectors, wherein each of the first slides is configured to receive the first glide wheel and allow it to roll along at least part of the length of the first slide;
- a pair of second slide rails, each attached to one of the pair of armrests;
