The magnetic car seat uses 50 x 1200 gauss magnets placed evenly throughout. The car seat cover insert is made of convoluted foam which in itself is known to improve circulation and enables the magnet to be placed on top of the foam, making the magnetic therapy that much more effective as it is closer to the skin. The magnetic car seat may assist in the relief of back, neck shoulder and hip problems, muscular aches and pains and arthritic pain. The magnetic car seat cover can be used in the car, truck bus office, lounge chair and wheelchair and also has a removable cover for hand washing only. ##MAGNETIC THERAPY & CAMERONS THOUGHTS## This was a product that I did not initially have in my magnetic therapy range. In the early days I sold a lot of magnetic pillows to couriers and truck drivers who put them behind their back. As you know if you sit still long enough your circulation slows down and the inflammation will build up. As in people with spurs in their feet. If they sit for a period of time the heel begins to hurt. Today after making the car seat I call the pillow the poor man's car seat. The new visco foam in the seat is beautiful to sit on. Really the car seat is a magnetic underlay that you can sit on. Another good secret that the truckies tell you, he car seat is good for haemorrhoid. CUSTOMER LETTER: Having suffered from sciatic pain over the past eight years I have found it impossible to sit for long periods, especially when driving, the pain would be excruciating. Since I purchased the magnetic car seat cover I no longer suffer the pain while driving and I have even driven interstate for over 12 hours with no sciatic pain occuring. I have now also purchased the magnetic underlay to give myself the magnetic therapy treatment throughout the night. thank you for these wonderful products: Mrs M Nelson
