Abstract: An articulating bed incorporates a support frame with a head end. Side frame members support and carry a carriage having a seat support. The carriage is mounted with wheels engaging the side frame members to translate from a first position through a range progressing toward the head end to a fully translated position. A first elevating frame rotates about an axle attached to the side frame members with the first elevating frame concealed within a depth profile of the side frame members in an unrotated position. First rollers carried by the carriage engage lower profile surfaces of the elevating frame and a second roller carried by the first elevating frame engages a lower surface of an upper body support pivotally attached to the seat support. Translation of the carriage from the first position to the fully translated position rotates the first elevating frame about the axle to articulate the upper body support.
