Abstract
A toy seat comprises a base with a seat mounted for movement between different levels above the base and a fluid chamber in the form of a bellows supports the seat on the base to move up and down. A hand pump is provided for supplying pressurized fluid to expand the fluid chamber to raise the seat to a level wherein suddenly the pressurized fluid in the chamber may be released to the atmosphere and the seat then settles downwardly until the pressurized fluid is again supplied to the chamber by manual operation of the pump. The toy seat also includes a whistle which is associated with an exhaust or release valve so that a whistling sound is produced whenever pressurized fluid from the seat supporting chamber is released.
