Joydivision "Elastic" Spring Up To 60kg

A replacement spring for a sex swing, rated to sixty kilos, and the rating is the whole point: a spring carries the full load and it is not the part to guess on. This is the extra-elastic one, which gives more bounce at a lower body weight than a stiff spring does. Check what your swing came with before ordering, and replace a spring that has started to open rather than waiting.
