Box spring assembly support spring

In a box spring assembly having a frame and a support deck disposed a predetermined distance above the frame, a support spring comprising a unitarily formed body having a pair of side-by-side yieldable portions including upper and lower ends, a mounting bar means extending between said upper ends of said yieldable portions for securing said support spring to the support deck, said mounting bar means including an end section extending from each of said upper ends of said yieldable portions and a connecting section extending between said upper end sections, said connecting section having a zig-zag shape and including a middle portion substantially parallel with both of said end sections, mounting foot means extending from said lower ends of said yieldable portions for securing said support spring to the frame and orienting said yieldable portions in a substantially vertical plane, said yieldable portions each including a substantially vertical upper column section and a substantially vertical lower column section connected together by a laterally extending middle section configured to bend within said substantially vertical plane in response to downwardly directed loads, said middle section of one of said yieldable portions being configured in a direction opposite of said middle section of the other of said yieldable portions.
