Abstract
A quiet, non-binding collapsible spring mechanism for resiliently supporting a mattress includes a system of collapsible, sinuous springs, each having hooked ends for silencing the mechanism during use or collapse, as well as central offset portions for enabling the sinuous springs to compress to a greater extent than heretofore. Both rigid and yieldable support structures connect the spring mechanism to an item of furniture.
