ABSTRACT The spring core for a mattress consists of several, identically formed coil springs arranged in rows side by side, each of which is formed of a wire piece and has an upper and a lower, mutually aligned end spiral, each being bent approximately in U formed and their opposite legs being joined together by a base web, with adjacent coil springs being joined together at their end spirals along abutting legs by helical connecting springs. To obtain an arrangement in rows and columns of all springs at right angles, the length of one leg is greater than the length of the other leg, all coil springs being oriented alike with the exception of an edge region of the spring core.
