ABSTRACT:
A spring-action chair comprising a seat frame having left and right sides and left and right spring-action support means rigidly secured to the left and right sides of the seat frame for elevating the seat frame above the ground. Each support means comprises an elongated, continuous support member of composite configuration having sections which include a first section extending upwardly and rearwardly from a first ground engaging end along a first angle, the member then having a first reversed bend in an elevated horizontal intermediate section extending forwardly therefrom, adjacent the seat frame to a second reversed bend, with the member then having a second angular section extending downwardly and rearwardly at a second angle and terminating at a second ground engaging end. The first ground engaging end is spaced transversely from the first ground engaging end, with the first and second angular sections bypassing one another with a lateral spacing between them normally being maintained to avoid contact between them, so that the left and right support members when secured to the sides of the seat frame can act in unison as elongated spring members for transmitting a rocking motion to the seat frame when pressure is applied from the seat frame toward the support members.
