Abstract: A spring counterbalanced folding wall bed having a vertically disposed shell including side walls spaced from each other and a bed frame pivotally mounted to the shell for movement between an open position and a closed position. In the open position the bed frame is substantially horizontal; in the closed position the bed frame is substantially vertical and between the side walls. A spring is mounted between a head end of the bed frame and one of the side walls and is biased to retain the bed in the closed position. One end of the spring is secured to the head end by a first pivotal connection and the other end of the spring is secured to the side wall by a second pivotal connection. At least one of the first and second pivotal connections are movable so that the length of the spring can be adjusted, whereby the spring force can be adjusted.
