Airhawk is the leading pioneer in patented Air Cell Technology since 1973. This groundbreaking technology was originally invented for wheelchair users. People who spend up to 12 hours seated each day are at great risk for painful and sometimes life-threatening pressure ulcers. The inventor, Robert H. Graebe, spent years developing a clinically proven solution to the problem. Ultimately, he created a remarkable cushioning technology that equalizes forces over weight-bearing areas of the body, which relieves dangerous pressure points. Mr. Graebe also discovered that his patented Air Cell Technology has even more extraordinary properties than just pressure equalization in medical applications – it also controls vibration and absorbs shock! Truck drivers who spend hours strapped into the seat of an 18-wheeler, motorcycle riders who are at the mercy of engine and road vibrations, and office workers who spend long hours seated in a chair, experience significant fatigue, numbness, and even health risks such as spinal column compression.
