Grevitrine couch — Durable equipment that can withstand loads of up to 120 kg. The device is very stable and weighs a maximum of 11 kg. The exercise machine does not take up much space and is easy to fold. The couch can accommodate people with a height of 1 to 2,10 m.

The operating principle of the equipment is to provide dosed stretching of the spine. The level of impulses depends on the shape of the back and the degree of its curvature. The surface of the couch is made of transverse ribs, which are elastically mounted on strips of a longitudinal stretched configuration. The parts are slightly inclined in the places where the patient's head and legs will lie.

The supporting surface is made in the form of a headrest with a cervical protrusion and a support area (for the shins). When the device interacts with the human body, the impulses begin to move in the direction from the lower back to the neck. Contact is made through the epithelium, connective muscles and tissues, which ensures longitudinal traction of the spine.
