The MÖV DS is a descent only stair chair that is ergonomically designed for safe and efficient transport of non-ambulatory, disabled or wounded individuals down stairs during a care facility or multi-floor building evacuation. The MÖV DS chair is lightweight and eliminates the need to lift or carry even bariatric patients. With minimal training required, the color coded action knobs and levers make the MÖV DS intuitive and easy to operate.
