A bed for multipurpose maternity care uses includes an elevationally adjustabel bed frame carried by transversely spaced lift mechanisms that permit the bed frame to nest between the lift mechanisms as it is raised or lowered with respect to a supporting base. An upper mattress assembly, including a seat and back rest, are pivotally mounted across the top of the bed frame. The bed frame includes a forwardly open cavity having guides for receiving a longitudinally movable lower mattress assembly at all elevational positions of the bed frame relative to the base. Elevationally movable outer supports mounted on the bed frame engage and support the lower mattress assembly when it is extended longitudinally outward from the bed frame. A pair of foot supports are movably mounted on brackets alongside the bed frame. The supporting linkages and brackets for the foot supports can be selectively connected to the outer supports for moving the extended lower mattress assembly in unison with the foot supports. The lower mattress assembly can be retracted under the seat regardless of the angular or elevational position of the seat relative to the base of the bed.

An elevationally adjustable bed, comprising: a rigid bed frame having opposed sides; a floor-supported base located elevationally beneath the bed frame; longitudinal mattress means on the bed frame for supporting the body of a user; and lift means operably connected between the bed frame and the base for elevationally raising or lowering the bed frame relative to the base, the lift means partially overlapping the bed frame in a nesting relationship; the lift means comprising: a base transport movably mounted on the base; parallel arms positioned in pairs alongside the respective sides of the bed frame, the paired arms extending respectively from two lower horizontal pivot connections on the base transport to two upper horizontal pivot connections; guide means on the base operably mounting the base transport for horizontal longitudinal movement relative to the base; and restraining means operably connected between the base and the arms for causing the arms to move angularly relative to the base about their two lower horizontal pivot connections in response to horizontal longitudinal movement of the base transport relative to the base.
