Collapsible, folding mattress support with adjustable elevating shoulder section

A foldable mattress support comprising:

• a first upper bar;
• a first lower bar;
• a second upper bar;
• a second lower bar;
• and
• a hinge that includes a central plate, a first angled flange and a second angled flange, wherein the first upper bar is pivotally attached to the central plate and pivots about a first axis, wherein the second upper bar is pivotally attached to the central plate and pivots about a second axis, wherein the first lower bar is pivotally attached to the central plate and pivots about a third axis, wherein the second lower bar is pivotally attached to the central plate and pivots about a fourth axis, wherein each of the first axis, the second axis, the third axis and the fourth axis is orthogonal to the central plate, and wherein the third axis is spaced farther apart from the fourth axis than the first axis is spaced apart from the second axis.

A method of manufacturing a foldable mattress support, comprising:

• bending a sheet of metal to form a first angled flange, a second angled flange and a central plate, wherein the first angled flange is bent from the central plate at a first crease, wherein the second angled flange is bent from the central plate at a second crease, and wherein the first crease is parallel to the second crease;
• pivotally attaching a first upper bar to the central plate such that the first upper bar pivots about a first axis;
• pivotally attaching a second upper bar to the central plate such that the second upper bar pivots about a second axis;
• pivotally attaching a first lower bar to the central plate such that the first lower bar pivots about a third axis;
• and
• pivotally attaching a second lower bar to the central plate such that the second lower bar pivots about a fourth axis, wherein each of the first axis, the second axis, the third axis and the fourth axis is orthogonal to the central plate, and wherein the third axis is spaced farther apart from the fourth axis than the first axis is spaced apart from the second axis.
