PURPOSE: A shaking bed is provided to take a comfortable and easy sleep like floating in the air and shake the bed in an unpredicted direction by a load in a sex life. CONSTITUTION: The shaking bed is configured to be freely deformable in an axial line direction and in a radial direction with respect to an external loading pressure by having an upper frame(20) supporting a mattress(10) and a coil spring(30) at each corner of the upper frame(20). When a rapid load is applied to the upper frame(20), the coil springs(30) are connected and fixed by arms(40) so that no plastic deformation occurs on the coil springs(30).
