    • An adjustable foundation (12) and process includes a mattress support surface (14) including a head and back section (18) hingedly connected to an intermediate section (20) at one end and a leg and foot section (22) hingedly connected to the intermediate section (20) at another end, wherein the intermediate section (20) includes a first portion (66) and a second portion (68), wherein the first portion (66) is hingedly connected to the head and back section (18) and the second portion (68) is hingedly connected to the leg and foot section (22). The intermediate or seat section (20) 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 (18). 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 (18). By doing so, a prone user does not have to shift his position on the mattress (402) in order to accommodate the inclination or declination.
