The Kit, Mattress, PRO 28Z by Ferno delivers a specialized patient comfort and safety surface engineered to attach directly onto the articulating sections of the PRO 28Z convertible chair-cot. Designed to endure the rigorous physical demands of daily emergency medical service responses, this segmented mattress set bends seamlessly alongside the cot frame as it transitions between flat stretcher and upright chair configurations. The non-porous outer fabric prevents the absorption of bodily fluids and environmental contaminants, while the high-density interior padding provides essential pressure management to stabilize and support patients throughout long-distance transports.
