A bed covering or blanket apparatus for accepting and distributing a pressurized flow of conditioned air into a zone around the body of a bed occupant. The apparatus includes an upper layer and lower layer of differing air permeability, joined to form a flow cavity between them for the pressurized air. A plurality of joining methods between the upper and lower layer is provided within the flow area to prevent the blanket from ballooning under the pressurized airflow. The bed covering or blanket apparatus contains means to cover an entire bed while directing pressurized conditioned air to specific zones of the bed. There is connection of two independent supplies of conditioned air into a single top layer of bedding under which multiple bed occupants sleep, to evenly distribute such independent supplies into specific dual zone areas. The apparatus achieves its function by utilizing materials that are ordinarily used in existing bed linens and comforters.
An adjustable power bed layer that has a bed frame that folds from a flattened state to a folded state and from a flattened state to an adjusted state. The bed frame has an inner and outer frame that nest with each other in the flattened state. Head side and foot side actuators drive sliding members back and forth along respective tracks to pivot respective articulating frames between the flattened and adjusted states. The articulating frames are part of one of the inner and outer frames and the tracks are connected to the other of the inner and outer frames. In the folded state, the bed frame is positioned to that one of head side and foot side actuators becomes accessible for maintenance and servicing from above depending upon which way the bed frame is folded about its folding pivot.

A bed lift mechanism that has linkages and has an actuator connected structure that is movable from a non-actuated position to two or three actuated positions. One set of linkages lifts the bed frame with the actuator connected structure moved into an associated one of the actuated positions and then push another set of linkages as the actuator connected structure is moved into another of the actuated positions. In the case where there are three actuator positions, further linkages move down a bed frame slotted bracket to initially lift the bed frame and as they reach and end of the slotted bracket as the actuator connected structure is moved to a different actuator position, the one set of linkages pull together to lift the bed frame vertically.
