摘要 |
A spring assembly for bedding and furniture which includes a support frame and a grid unit disposed above and in general vertical alignment with the frame, the grid unit including a border wire and cross wires arranged in a criss-cross pattern on said border wire. A plurality of upright spring modules are arranged in a predetermined pattern on the grid unit and supported on said frame, each of the modules being attached in a clipless manner at the upper end thereof to the grid unit so as to be connected to the unit in a manner such that up and down movement of the grid unit results in up and down compression and expansion of the spring modules. Each of the spring modules being a one-piece wire spring of tapered shape to enable spring modules to be arranged in nested stacks for shipping and storage.
