Based on the experience of the Apollo 11 astronauts, who spent their rest periods on the lunar module floor, hammocks designed to attach to the interior of the LM ascent stage were provided for the lunar module astronauts from Apollo 12 on. Made of beta cloth and adjustable with straps, the hammocks helped reduce the cooling effects of contact with the cabin floor (the Apollo 11 astronauts had reported being too cold to sleep comfortably) as well as a softer support.
Two unflown hammocks (S/N 0004 and S/N 0006) were transferred to the Smithsonian in 1975 from the Kennedy Space Center.
