True REST(r) (Reduced Environmental Stimulus Therapy) is a zero-gravity environment that allows the mind and body to completely let go, relax, and reset. Epsom Salts are buoyant enough to make floating on water feel like you’re 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.
