A spring assembly comprises upper and lower superimposed webs of strong yet flexible material which are connected together at spaced intervals to define a plurality of similar pockets (30, 31, 32, 33...) arranged side-by-side in a parallel relationship, and a length of continuous spring (20) inserted into each successive pre-formed pocket. Apparatus and a method of manufacturing the spring assembly are also disclosed. |
