Abstract: An innerspring assembly includes a first plurality of interconnected strings of pocketed first springs. A second plurality of strings of springs is provided and so incorporated in the innerspring assembly that at least one string of springs of the second plurality is placed between two neighboring strings of the first plurality of interconnected springs, wherein the second springs have a diameter which is smaller than a diameter of the first springs.

Abstract: A pocketed spring core includes a plurality of springs which are arranged sequentially in rows to form parallel adjoining spring strands, wherein each of the springs is supported in a pocket made of flexible material. A first cover sheet is placed over and connected to the spring strands, and a second cover sheet is placed under the spring strands and connected thereto. At least one of the first and second cover sheets has predetermined regions which are opened in a direction transversely to a longitudinal extension of the spring strands by a plurality of slots to thereby form strips.

Abstract: An innerspring assembly, preferably pocketed spring core, includes a plurality of interconnected springs having a same height and arranged to form adjoining rows to provide a resting area. At least several of the rows are arranged in relation to the respectively neighboring rows offset in height.
