A collapsible sofa bed movable between an expanded configuration and a collapsed configuration includes a frame including a plurality of scissor assemblies. Each scissor assembly includes a first frame member pivotally coupled to a second frame member at a pivot point. Frame members of adjacent scissor assemblies are coupled to one of a first connector assembly and a second connector assembly. At least two backrest support members are coupled to the frame. Each backrest support member is slidably coupled to a corresponding first frame member and has a lower end that is pivotally coupled to a corresponding second frame member. Each backrest support member is pivotally movable with respect to the corresponding second frame member.

Sofa air bed

A collapsible bed frame includes a first cross unit including a first link member pivotally coupled to a second link member at a first pivot point, and a support unit operatively coupled to the first cross unit. The support unit includes a first slider that is slidably coupled to the first link member. A first support member has a first end that is pivotally coupled to the second link member and an opposing second end that is pivotally coupled to the first slider. A second slider is slidably coupled to the first support member. A second support member has a first end that is pivotally coupled to at least one of the second link member and a connector operatively coupled to the second link member, and an opposing second end that is pivotally coupled to the second slider.

Collapsible bed frame including cross units and method for constructing collapsible bed frame

A collapsible structure is movable between an expanded configuration and a collapsed configuration. The collapsible structure includes a plurality of collapsible scissor assemblies. Each scissor assembly includes a first frame member pivotally coupled to a second frame member at a first pivot point. Frame members of adjacent scissor assemblies are coupled to a first connector assembly or a second connector assembly. A support assembly is coupled to a first scissor assembly and includes a member pivotally coupled at a first end to the first connector assembly or the first frame member and slidably coupled at an opposing second end to the second frame member.
