ABSTRACT:
A mattress of an adjustable bed is readily bendable at joints connecting non-bendable sections. Each non-bendable section is composed of a non-bendable assembly of rows and columns of spring coils held in place by top and bottom border wires, edge support elements between the border wires and longitudinal straps on the top and bottom of each column of coils to provide a durable spring assembly with uniform support throughout. A bag assembly of sturdy fabric has a series of pockets to hold the spring assemblies in place spaced apart from one another by a fixed gap defined by a transverse hinge portion of the bag assembly positioned at the mid thickness of the mattress so that the joints formed by the hinge may bend either way for reversing the mattress top to bottom. Resilient foam bars fill the gaps between pockets and conventional mattress padding and covering are secured to the bag assembly.
