A lift assembly for raising and lowering a load includes a first member, which is adapted for resting on a reference surface, and a second member, which defines a support surface for supporting a load.

The drive assembly is adapted to move the second member from the initial position at a progressively increasing speed to an intermediate position and after which at a progressively decreasing speed until the second member is moved to the final position.
