The invention which is the subject of this application relates to a lifting device which is inflatable and is for use for the lifting of persons so that they can move from and onto an object such as a chair, bath or bed. The device includes an inflatable seat which is moved from an inflated position whereupon the person can place themselves thereon to a deflated position whereupon the person is effectively sitting on the object and, connected thereto there is preferably provided a blower unit for supplying pressurised gas such as air, a control valve for operation of the blower unit and a flow valve for controlling the flow of air into the inflatable seat. The inflatable seat is provided to have at least two compartments which are inflatable and the relative rate of inflation of each of the compartments is controlled by the flow valve dependent upon the pressure sensed by the flow valve in each of the compartments at any instant during deflation and inflation. By providing at least two compartments, the person on the inflatable device can be raised and lowered in a relatively stable plane regardless of the particular position of the person on the compartment of the seat device and, furthermore, the movement of the person during inflation and deflation on the inflatable seat is taken into account by alterations of the flow valve. In a further feature, supports may be provided integral or additional to the inflatable seat so that the person can place their arms thereon and gain support therefrom.
