This sleep restraint was used in the Command Module "Columbia" on the Apollo 11 mission, the first to land humans on the Moon. Restraints were placed under the left and right couches and on top of the right couch during flight and could be rolled and stowed when not in use. The lightweight fabric with zippered front is meant to hold the astronaut from floating around the cabin in the zero-gravity environment of space. One of the restraints was also used to stow spacesuits during reentry. Straps on the back tie the sleep restraint to the inside of the cabin.
NASA transferred this sleep restraint to the Smithsonian Institution in 1972.
