Abstract
Systems and methods include a spring-coil assembly having non-linear load-deflection characteristics that are substantially similar to foam. In particular, the systems and methods described herein include a first set of encased springs that are in a partially compressed state and a second set of shorter springs. These two sets of springs may be arranged in alternating rows such that the resulting spring-coil assembly displays non-linear load-deflection characteristics similar to foam.
