A coil spring mattress and adjustable foundation assembly includes a coil spring mattress; and an adjustable foundation including a mattress support surface including a head and back section hingedly connected to an intermediate section at one end and a leg and foot section hingedly connected to the intermediate section at another end, wherein the intermediate section includes a first portion and a second portion. The intermediate or seat section is configured to increase in length upon articulation of the head and back section and/or the leg and foot section from a flat position or an increase in inclination of any section. Likewise, the intermediate or seat section is configured to decrease in length upon articulation of the head and back section and/or the leg and foot section from an inclined position to a flat position or a decrease in length upon declination of any section.

Adjustable mattress assemblies and processes including an adjustable mattress foundation dimensioned to support a mattress configured to accommodate two supine users during use thereof includes a foundation frame including a first sub-foundation configured with at least one motorized actuator to effect inclination or declination of the mattress support surface and an abutting second sub-foundation free of a motorized actuator. The second foundation is mechanically coupled to the first foundation such that articulation of the first sub-foundation results in a similar articulation in the second foundation. The first and second foundations have similar length, height and width dimensions, which collectively approximates the size of the oversized mattress configured to accommodate two supine users, e.g., king size, queen size, California king size, or the like.

An adjustable foundation and process includes a mattress support surface including a head and back section hingedly connected to an intermediate section at one end and a leg and foot section hingedly connected to the intermediate section at another end, wherein the intermediate section includes a first portion and a second portion, wherein the first portion is hingedly connected to the head and back section and the second portion is hingedly connected to the leg and foot section. The intermediate or seat section is configured to increase in length upon articulation of the head and back section 18 and/or the leg and foot section 22 from a flat position or an increase in inclination of any section. Likewise, the intermediate or seat section 20 is configured to decrease in length upon articulation of the head and back section 18 and/or the leg and foot section 22 from an inclined position to a flat position or a decrease in length upon declination of any section. By doing so, a prone user does not have to shift his position on the mattress in order to accommodate the inclination or declination.
