The Dolphin Fluid Immersion Simulation (FIS) System provides automated pressure redistribution by allowing the surface to conform to the body, reducing pressure concentration and tissue strain as movement occurs. The system continuously adapts in real time and is available in multiple configurations to fit a range of bed frames and care environments.
The Low Profile Therapy System delivers this same Dolphin FIS technology in a lower-profile 8-inch mattress configuration. The mattress maintains continuous pressure redistribution while offering compatibility with environments where a reduced mattress height is preferred. An integrated foam support layer provides continuity of support during power interruptions, without altering the underlying Dolphin FIS therapy.

Powered by the AutoVector® Control Unit, the system operates automatically, adapting in real time to body shape, weight distribution, and movement without manual adjustment. Designed as a standalone therapy system, the Dolphin FIS Low Profile mattress is compatible with a wide range of bed frames.
