A collapsible bed frame () for supporting a mattress, the collapsible frame () having a number of frame members (). A number of pivots () connect pairs of the frame members () at the midpoints of the frame members () to make a number of scissor pairs (). Pivot assemblies () pivotally attach the upper ends of the frame members () to upper connector assemblies (), and pivotally attach lower ends of the frame members () to feet (), thus connecting the scissor pairs () to form an extended scissors-frame assembly (). The upper connector assemblies () form a support surface for a mattress.

Collapsible bed frame

A collapsible chair (), having a frame assembly () including a number of frame members (), the upper ends of the frame members () being pivotally attached to upper pivot assemblies (), and the lower ends being pivotally attached to lower pivot assemblies (). The frame members () are connected such that the frame assembly () as a whole expands outwardly from a central area () when the chair () is unfolded. The frame assembly () further including rear members () and front support members (), and a pair of rigid arm rest members (). A pair of pivot mechanisms () and a pair of slide-pivot mechanisms () attach the rigid arm rest members () to the frame assembly () such that the rigid arm members () are allowed to slide and pivot as the chair () collapses or expands.

Hard arm chair with sliding arm mechanisms

An inclining collapsible bed ( ) including a mattress ( ) and a support frame ( ), including a number of frame members ( ) where the upper ends of the frame members ( ) are pivotally attached to upper connector assemblies ( ), and the lower ends are pivotally attached to feet ( ). The support frame ( ) includes an inclining portion ( ) having at least one inclining support member ( ) and at least one angle retention mechanism ( ), which is preferably an adjustable clip ( ). The bed ( ) is configured to optionally use an air mattress ( ), which can be attached to the frame ( ) so that the bed frame ( ) is self-expanding in response to the inflation of the air mattress ( ). Also an inclining collapsible bed frame ( ).
