True REST® (Reduced Environmental Stimulus Therapy) is a zero-gravity environment that allows the mind and body to completely let go, relax, and reset. Using 1,000 pounds of Epsom Salts, the buoyancy of the water makes floating on water feel like floating on air. By eliminating the forces of gravity pulling on the musculoskeletal and nervous systems, you can effortlessly relieve pain, relax, recover, and improve sleep in this unique state.
