Spring core with integrated cushioning layer

A spring core, comprising:

• a plurality of coil springs, each coil spring having an upper portion and a lower portion, the upper portion and the lower portion collectively defining an interior cavity of each coil spring;
• a continuous upper fabric layer covering the upper portion of each coil spring and extending into the interior cavity to define a recess in the interior cavity of each coil spring;
• a cushioning layer positioned atop the continuous upper fabric layer and extending into the recess, said cushioning layer having a lower surface adjacent to the plurality of coil springs and the continuous upper fabric layer wherein the lower surface is free of foam molded recesses and engages said continuous upper fabric layer, said cushioning layer defined by a precursor that is poured on to the continuous upper fabric layer wherein said cushioning layer forms within the recess of each of said plurality of coil springs and between springs, and said cushioning layer being bonded to the continuous upper fabric layer when cured;
• and,
• a second continuous lower fabric layer covering the lower portion of each coil spring, said second continuous lower fabric layer connected to said continuous upper fabric layer around each coil and extend into the interior cavity of each coil spring to define the recess.
