The problem of a split between two mattresses is eliminated by giving each person on a king-sized bed the capability for adjusting the head and/or foot portion of the mattress to any position, without disturbing the bed partner. A serpentine "S" design is provided to separate the head and foot portions of a single mattress at a distance extending over approximately two feet from the headboard toward the foot of the bed and extending over approximately two feet from the foot of the bed toward the headboard. There is approximately three to four feet of the mattress in a central portion without any separation where most of the body's weight is concentrated and which provides support and comfort for two people in a single king-sized mattress having adjustable head and foot portions.
