A spring deck for supporting padding material in seating or bedding structures, said deck comprising:
- a. an open rigid frame having generally parallel side legs,
- b. a wire fabric sheet substantially covering said frame and consisting of a pair of resilient, normally straight side wires disposed respectively adjacent the side legs of said frame, and a continuous series of closely spaced cross wires extending transversely between and secured at their ends to said side wires, and
- c. means connecting each of said side wires unyieldably to the adjacent side frame leg at spaced apart points along the length thereof, the points of attachment of one of said wires to its frame leg being staggered relative to the points of attachment of the other side wire to its frame leg to lie therebetween, considered longitudinally of said side wires.
