A powered rocking bed comprises a body support member connected to at least one stationary pivot disposed there beneath and connected via at least one driving linkage to an oscillating powered driver also there beneath, the driving linkage and the pivot configured to move both a head-end and a foot-end of the body support member in a longitudinally complementary oscillating crescent-shaped wave motion comprising a rising convex wave followed by a falling concave wave and inertial transitions there between. The crescent-shaped inertial wave motion is configured to resemble an ocean wave based on a wind blowing across the rising convex wave. A predetermined distance of the stationary pivot from the supporting structure may determine a slope of both the convex and the concave wave motion. The slope may be maximized based on the pivot located in a plane with the body support member and flattened located at a distance therefrom.
