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.

A mechanism for transforming furniture from a sitting position to a lying down position has right and left jacks with identical design, which are a mirror reflection of each other, connected by a synchronisation mechanism. Each jack has a fastening plate which attaches the jack to the furniture body, angle bars, upper and lower for connecting with the mattresses, a spring and a front pull rod and rear pull rod with centre arms. Each jack has a backrest driving sub-assembly created from a backrest rotation pull rod and support to be connected with the backrest of the furniture, whereas the backrest rotation pull rod is connected in an articulated manner on one end with the bottom end of the rear pull rod, and on the second end is connected in an articulated manner with the support connected in an articulated manner to the fastening plate.

A variety of apparatuses are disclosed, including, in one embodiment, a sofa bed, that includes opposing arm rest sections, a back section, and a pull-out section, that includes a honeycomb structure disposed between the opposing arm rest sections, where the honeycomb structure of each pull-out section is configured to change between an extended and a non-extended position.

A cushion, mattress or mattress section for a convertible furniture article defines a plurality of apertures, such as slits or slots or recesses, extending into or through the cushion or mattress section that are cut in a direction at an angle to the first length of the mattress section. The cushion or mattress section expands from its first length to a second length that is longer than the first length upon applying a stretching force to the cushion or mattress section and thereby positioning the mattress section into the open or sleeping configuration. Expansion is due to resilience of the material forming the mattress or mattress section in combination with opening of the apertures. The sleeping surface of the mattress or mattress section may remain substantially planar in both the open (sleeping) position and closed (seating) position.

Provided are an extendable seat frame and a furniture thereof. The extendable seat frame includes: a fixed base; a seat frame main body, configured to move relatively above the fixed base; and an extension apparatus, configured to be rotatably connected to the fixed base and rotatably connected to the seat frame main body so as to enable the extendable seat frame to switch between a retracted state and an extended state. Further, the extension apparatus includes at least an extension part, one end of the extension part is rotatably connected to an end of the seat frame main body that is away from an extending direction, and the extension part is configured to drive the extension part to flip in response to the seat frame main body moving towards the extending direction.

A sofa includes: a base assembly comprising a base that comprises at least one of a first connection member and a second connection member, wherein the first connection member is configured to detachably connect with a base connecting member, two bases are detachably connectable to each other through the first connection member and the base connecting member, the second connection member is configured to detachably connect with a backrest connecting member, thereby allowing a backrest connected to the backrest connecting member to be detachably connected to the base assembly.

A linkage mechanism for a three-section sofa bed is provided. The linkage mechanism includes a first link assembly, a second link assembly, a third link assembly, and a locking assembly, where the first link assembly includes one side pivoted to a front sofa cushion and the other side pivoted to a fixed base frame of a sofa frame; the first link assembly is provided with a locking hole; the second link assembly includes one end pivoted to a middle sofa cushion and the other end pivoted to a middle segment of the first link assembly; the third link assembly includes one side pivoted to a rear sofa cushion and the other side pivoted to a pivot position of the first link assembly pivoted to the fixed base frame; the locking assembly is located at a side of the first link assembly close to the front sofa cushion.

A sofa includes: a base assembly comprising a base that comprises at least one of a first connection member and a second connection member; wherein the first connection member is configured to detachably connect with a base connecting member, two bases are detachably connectable to each other through the first connection member and the base connecting member; the second connection member is configured to detachably connect with a backrest connecting member, thereby allowing a backrest connected to the backrest connecting member to be detachably connected to the base assembly.

The present invention discloses a new sofa, comprising a left armrest and a right armrest, a first mounting base is fixed respectively on the left armrest and the right armrest, a placing groove is opened respectively in the two first mounting bases, a second mounting base is fixed on one side of the left armrest, a USB port is arranged on one side of the second mounting base, and an interface is arranged at the bottom of the left armrest on its other side; two first mounting plates, wherein one of the first mounting plates is fixedly arranged on one side of the left armrest, a mounting rod is fixed between the other first mounting plate and the right armrest. The size and shape of the sofa can be simply adjusted for users to install and disassemble the sofa, charge and use electronic equipment, and stably place cups.
