Claim Text:
1. An advanced conformance encased coil spring unit comprising: a plurality of coils interconnected in a substantially rectangular array of columns and rows, each coil being encased in an encasement material, and each column extending between two opposing long edges of the advanced conformance encased coil spring unit with the encasement material of each coil in each column connected to the encasement material of an adjacent coil in the same column with a section of sheet material extending between the adjacent coils to form a continuous strand of coils extending between the two opposing long edges of the advanced conformance encased coil spring unit; a partial separation defined in less than all the sections of sheet material extending between adjacent coils, each partial separation extending vertically from an upper edge of the sheet material proximate to a support surface of the advanced conformance encased coil spring unit toward a lower edge of the sheet material proximate to a lower surface of the advanced conformance encased coil spring unit, the partial separation having a terminal end opposite the upper edge of the sheet material; and one or more attachment points between the encasement material of each coil in a column and the encasement material of a horizontally adjacent coil in an adjacent column, the one or more attachment points located in a plane situated between the lower edge of the sheet material and the terminal end of the partial separation.
