Abstract

This invention is a new mattress design. A replaceable foam unit containing the user's chosen firmness, or two different levels of firmness, one level being on the top of the unit, and the second firmness being on the bottom of the unit, sits atop a standard spring unit. The replaceable foam unit and standard spring unit are encased and held firmly together by a constricting and expanding fabric cover. A zipper on the cover allows for the cover to be opened, revealing the replaceable foam unit. The replaceable foam unit can then be flipped so that the second level of firmness faces upwards, and the user can experience a brand-new level of firmness. Or, the replaceable foam unit can be removed completely and replaced by a new replaceable foam unit, thus eliminating the need to replace the standard spring unit once disposal of a user's bed becomes necessary.
