A control assembly for an adjustable bed includes push-button devices for selectively engaging associated clutches. A single device may be actuated to engage a single clutch. Alternatively, a plurality of devices may be actuated simultaneously to engage a plurality of clutches. As any one or more buttons is pushed, a slide bar sequentially releases all devices and latches those for which buttons are pushed to the clutch-actuating position. A single crank provides torque for a transmission thereby clutched to lift screws.
