Abstract
A pocketed coil spring assembly comprising a plurality of transversely extending integrally connected fabric blocks. Each block is defined between two sheets of fabric by transversely extending lines of attachment of the sheets to each other. Successive lines of attachment are located alternatively in the upper and lower planar surfaces of the assembly. The blocks may be further connected with fasteners in one of the planar surfaces of the assembly. The blocks may contain either continuous bands of coil springs or individual coil springs, but in any event, the springs within adjacent blocks are oppositely oriented to create a balanced spring assembly in which there is no tendency for the springs to tilt upon compression of the assembly.

A mattress comprising:
- a pocketed spring assembly having an upper and lower planar surface in top and bottom planes respectively, said assembly comprising a plurality of transversely extending integrally connected fabric blocks, each block containing a plurality of coil springs, each coil spring having a first and second end turn and a plurality of central convolutions defining an axis, wherein said blocks are defined between two sheets of fabric by spaced transversely extending lines of attachment of the sheets to each other, said lines of attachment being located in the upper and lower planar surfaces of said assembly, and successive lines of attachment being alternatively located in said top and bottom surfaces of said assembly,
- a mattress pad covering a surface of said assembly,
- a fabric covering encasing said pad and said assembly.
A pocketed spring assembly having an upper and lower planar surface in top and bottom planes respectively, said assembly comprising:
- a plurality of transversely extending integrally connected fabric blocks, each block containing a plurality of coil springs, each coil spring having a first and second end turn and a plurality of central convolutions defining an axis, wherein said blocks are defined between two sheets of fabric by spaced transversely extending lines of attachment of the sheets to each other, said lines of attachment being located in the upper and lower planar surfaces of said assembly, and successive lines of attachment being alternatively located in said top and bottom surfaces of said assembly.
A pocketed spring assembly having an upper and lower planar surface in top and bottom planes respectively, said assembly comprising:
- a plurality of transversely extending integrally connected blocks, each block containing one continuous band of coil springs, said band of coil springs being formed from a single length of wire formed into a plurality of transversely extending parallel coil springs, each coil spring having a first and second end turn and a plurality of central convolutions defining an axis, wherein said blocks are defined between two sheets of fabric by spaced transversely extending lines of attachment of the sheets to each other, adjacent blocks being hingedly connected by said lines of attachment, said lines of attachment being in the upper and lower planar surfaces of said assembly, said lines of attachment alternating between said upper and lower planar surfaces.
A pocketed spring assembly having an upper and lower planar surface in top and bottom planes respectively, said assembly comprising:
- a plurality of transversely extending hingedly connected fabric blocks, each block containing a row of springs, wherein said blocks are defined between two sheets of fabric, a first sheet and a second sheet, each sheet containing a plurality of folds therein, said folds separating said blocks from one another and extending inwardly from one of said upper and lower planar surfaces, successive folds being alternatively located in said first and second sheets.
