Abstract: A free floating bunk bed includes a bed framework supported on a base framework which in turn is supported on a bed support floor of a truck or tractor cab. The base framework includes first and second subframes. The bed framework is supported on the base framework by a suspension means which includes two pairs of rigid hanger brackets each pair is pivotally mounted to a one of the suspension subframes. Hanger straps extend between the end of each hanger bracket and a portion of the bed framework spaced below the end of the hanger bracket, and two universal joints connect each hanger strap between the end of its hanger bracket and the bed framework. A pair of opposed and balanced compression coil springs are operative between the base framework and each pair of hanger brackets to tend to keep the hanger bracket from pivoting with respect to the base framework.
