Abstract
A method for using a back lifting chair designed for treating and preventing back problems by monitoring posture, weight distribution, and sitting duration of an occupant of a seating device, and reducing pressure on a user's spinal disc by adjusting the user's posture. The method allows for an up-lifting motion on the user's torso, reducing the weight and pressure asserted on the lumbar disc, and preventing any further damage to it. The method allows for an upward and downward movement, hence partially or completely lifting the user from the seat, effectively reducing the pressure on the user's spine and back. The upward motion can be initialized by the user, or alternatively, it can be automatically activated by the weight sensor installed on the seat device which detects the prolonged period of sitting.
