ROHO, Inc. was incorporated in 1973 by Robert H. Graebe. He began his career as an electrical engineer, but while working on a project for a hospital, he became concerned about a means to heal ischemic ulcers or pressures sores, as they are commonly called. Through intense research and development, Mr. Graebe invented ROHO DRY FLOATATION technology, named such because ROHO medical cushions and mattresses mimic the properties of water, in a dry, air-fluid environment. This technology has been proven in countless clinical studies to assist in effectively healing as well as preventing pressure sores.
