A device for exercising legs whilst in a seated position. The device has a base unit 12 having the central part of its lower surface 13 convexly curved along the longitudinal axis and two foot rests 11 pivotally secured by pins 16, ball and socket joints (33, fig 6) or snap-fit connectors (44, fig 10) to the upper surface 10 of the base unit. Springs (26, fig 5) may be incorporated between the base and the foot rests. The foot rests may have raised lips 17 to prevent the feet slipping from the device, or straps or contoured surfaces (34, fig 9) may be provided. In use, the user presses down on a foot rest with one foot causing a reciprocal motion upwards to the other foot, and then repeats the process with the other foot, imparting a rocking motion to the device. The device is intended to reduce the risk of circulatory problems developing as a result of sitting in cramped conditions for an extended period of time, eg on long-haul aircraft flights. In a second embodiment, rockable foot rests may be attached to a stationary base unit.
