Abstract
The mattress assemblies have an array of springs extending from a sheet. Each spring in the array may be manufactured by choosing a position for the spring, cutting a profile of the sheet spring in the sheet, peeling back or bending the profile or tab of the sheet, and shaping the profile to form the sheet spring. The array of springs may be formed from creating a plurality of such springs along rows and columns. In certain embodiments, multiple sheets may be stacked to form the sheet spring array.

A method of manufacturing a sheet spring innercore, comprising:
- providing a first metallic sheet;
- forming a first plurality of sheet springs in the first metallic sheet member, each sheet spring having an adjacent opening and each sheet spring having a serpentine shape and extending along a longitudinal axis being perpendicular to the metallic sheet, the springs being compressible along the longitudinal axis in response to a force applied along the longitudinal axis.
A furniture spring assembly comprising:
- a first metal base plate;
- a plurality of sheet springs each next to a respective opening, and each fixed at one side and extending upward along a longitudinal axis substantially perpendicular from the metal base plate and having a serpentine shape, respective springs being compressible along the longitudinal axis in response to a force applied along the longitudinal axis.
