The Engineering Solution to Suffering Back Pain

Soft cover. Zustand: As New. Colm Campbell (illustrator). 1st Edition. 160 pages. Original publisher's pictorial card covers. Colm Campbell, an engineer with a serious back problem, studied how primitive tribes live. He designed and patented a method, Spinal System-S, which guarantees perfect sitting posture, thus simulating the low pressure in the spine when squatting. In the vast majority of cases this results in pain free sitting at home, in the car and in work. A fine copy without any damage, library stamps, inscriptions or other markings. Artikel-Nr. 003074
