An innerspring module consists of a plurality of coil springs joined together by helical wire fasteners in a generally rectangular configuration having dimensions which when assembled with other like modules in side-by-side and end-to-end relationship make up a completed modular innerspring assembly of the size and shape needed to make a twin, twin extra long, full, full extra long, queen and king size mattress. A top boundary wire assembly extends around the top peripheral edge of the completed modular innerspring assembly and a bottom boundary wire assembly extends around the bottom peripheral edge, in each case secured to adjacent coil springs by a double hook clip. A box spring module consists of a frame made up of end and side strips plus intermediate slats having a plurality of springs secured thereto and extending upwardly therefrom in a generally rectangular configuration having dimensions which when connected with other like box spring modules in side-by-side and end-to-end relationship make up a completed modular box spring assembly of whatever size and shape needed to support a twin, twin extra long, full, full extra long, queen and king size mattress.
