Abstract
Abstract A bed construction comprising a unitary frame member within which are removably mounted a pair of separate box spring units. A mattress mounted on the spring units is provided with a slit along its longitudinal axis which is aligned with the dividing line between the spring units. The bed appears to be unitary, but functions like a pair of separate beds, with each half being responsive to the body weight and movements of its occupant without affecting the other half or its occupant. A foldable frame member is provided for a king size bed.

Claim 1
Independent Claim
139 words
A bed construction comprising a pair of box spring units, each of said spring units comprising substantially one-half of the width of said bed, and a single mattress mounted on both of said spring units, said mattress having an elongated slit extending completely through the midportion of said mattress substantially along its longitudinal axis and in alignment with the dividing line between said spring units, the opposite ends of said slit being disposed substantially inwardly from the head and foot of said mattress, said slit and dividing line separating the midportion only of said bed into two separate adjacent sections, each of which is separately depressible in response to weight placed thereon in use without substantially affecting the other of said sections, the head and foot portions of said mattress beyond the opposite ends of said slit being unslit.
