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.
