ABSTRACT:
A spring chair has a seat frame and a base frame including an upper portion fixed to the seat frame, spaced front leg portions extending generally vertically down from said upper portions at the front of the seat portion, and base portions extending horizontally rearwardly from the leg portions to underlie the seat portion. The leg portions and base portions extend from a right angular bend portion and have lengthwisely extending openings. Unitary right angular springs inserted in the openings provide spring resilience to the bend portions which will restore them to normal position. The springs are preinserted in the linear extrusion strip which is bent to the base frame confuguration so that extrusion bending and spring bending occur simultaneously.
