Claim:
A lifting cushion that is wedge-shaped, comprising: a top part and a bottom part with connecting walls and fillable with a fluid, wherein the top part and the bottom part are a formable material and are joined to form an unbroken unit in a forward edge of the cushion, the forward edge is extended in relation to a front connecting wall, thereby forming a fore extended part that extends in front of and outside the front connecting wall, the front connecting wall extending substantially perpendicular to the bottom part in a filled state, the fore extended part is thin and stiff such that when the lifting cushion is filled with the fluid, the fore extended top part and the bottom part are expanded without preventing the fore extended part of the connecting wall from smoothing out and forming the fore part of the lifting cushion in a filled state, so that it is allowed to be interposable along a support under or between objects to be lifted, the top part and the bottom part have surfaces that are at least as large as a surface of the lifting cushion, the front connecting wall, sides, and a rearward edge of the cushion are a formable material, and a ratio of a height of the forward edge and a height of a rearward edge of an inflatable part of the cushion is approximately 1:3, and the lifting cushion has decreased wedge-shape toward the forward edge.
