Abstract: A transportation seat primarily adapted for use by an operator of a vehicle is disclosed. The seat includes an air suspension base supporting a tubular seat frame to which seat back and bench cushions are attached. A track support frame is slidably mounted on the base for stepwise fore and aft adjustment. The seat frame is secured to the track support frame by an antislap mechanism which isolates the seat frame from jarring movement of the vehicle. A side saddle adjustment mechanism supports the seat frame on the track support frame permitting stepwise transverse adjustment of the seat frame relative to the base.

Carried between opposing parallel surfaces on the brackets is a fluid vibration eliminating assembly movably separating the pair of brackets. The assembly is carried in a dish or pan which is fixedly secured to at least one of the brackets and provision is made for accommodating a fluid valve for suitably pressurizing the assembly.
