Color: Red. Spinefitter by Sissel Back Trainer: Easy application for effective back training. The Spinefitter by Sissel is an elongated back trainer featuring 28 double-row ball structures that are ideally suited to the muscles close to the spine. The spinous processes glide between the rows of balls, mobilizing the body's own forces and relieving the spine. Your patient lies on their back on the Spinefitter, and the training can begin. The Sissel back trainer is particularly used in therapy, spinal gymnastics, yoga, or Pilates in both individual and group training. Thanks to its special shape, the neck and shoulder area can be relaxed even in a resting position. Product details: Material: Polyurethane (PU) integral foam. Dimensions (LxWxH): 84x12x6 cm.
