The normal swopper spring is constructed for a load weight of app. 60 – 120 kg. For all who need a bit more free space upwards or who love to swop very intensely, the spring STRONG is advisable. It tolerates stronger tension – up to app. 140 kg. Ideal for soft swinging and lively sitting "in XXL".
Another reason to opt for the STRONG spring can be that you want to sit as high as possible. Tall people (around 6.5 ft) or persons with extraordinarily long legs often prefer not to sink quite so deep into the material. Sometimes just a few centimeters are decisive.
