Abstract
Abstract A seat member is horizontally mounted on a pair of scissor-like arranged levers for movement in upward and downward directions. A fixed frame portion extends in a generally upward direction and is adjacent at least in part to the seat member. A shock absorber is pivotally connected to the seat end of the seat member and to the frame portion. A spring, whose tension can be adjusted, is also connected to both the seat member and to the fixed frame portion. The vertical position of the seat member is adjustable by changing the pivot connection of the shock absorber to different positions along the fixed frame portion.
