The Dolphin Fluid Immersion Simulation (FIS) Advanced Therapy Mattress Replacement is a replacement therapy surface only, designed to be used exclusively with a Dolphin AutoVector® Control Unit. This mattress does not function on its own and does not include a control unit, hoses, or bed frame.
When connected to a compatible AutoVector® Control Unit, the Dolphin FIS therapy surface uses Fluid Immersion Simulation technology to conform to the body and redistribute pressure dynamically as movement occurs. The surface continuously responds to changes in weight distribution and repositioning, helping reduce pressure concentration and soft tissue strain as part of a complete Dolphin FIS therapy system.
This product is intended for customers who already own a Dolphin FIS system and need to replace the mattress surface.
