A wave generating apparatus for generating waves in, for example, beds, chairs and the like. The wave generating apparatus can be constructed to include a motor and crank assembly connected to a flexible sheet and a stationary inertial member. The apparatus includes a flexible member and an oscillatory drive attached to the flexible member. The oscillatory drive includes a crank assembly having an axis of rotation and at least two link members each having opposed first and second end portions. The two link members are spaced apart a first pre-selected distance from each other and each is rigidly attached at their respective first end portions to the flexible member; and at least one elongate beam. The two link members are pivotally attached to the elongate beam, and the elongate beam is attached to the crank assembly for imparting oscillatory motion to the at least one elongate beam so that when the oscillatory drive is engaged, the at least one elongate beam undergoes oscillatory motion which produces transverse waves along the flexible member.
