Abstract
A protective bed includes a shield comprising bullet-proof and impact resistance material that surrounds a metal frame. The shield operably separates to provide access to an interior sleeping area. Quick access doors are located on either side of the bed. A ventilation system provides for climate control as well as filtering harmful substances from the air. A rebreather scrubs carbon dioxide from air within the unit to allow a user to close the unit to outside air.
