Cryo chamber (Earth-5875)

Cryo chambers are plastasteel pods with form-fitting gel beds which allow starship personnel to undergo cryosleep for long periods of time, commonly during slipspace jumps, which takes days, weeks, and even months to reach the designated location.

Notable models of cryo chamber include the Mark VII Personal Suspension Unit manufactured by the Weyland-Yutani Corporation for commercial freighters, and the Mark VIII Cryogenic Suspension Chamber, utilized by the UNSC on their warships. Cryo chambers are known as "freezers" in slang, as well as "the Admiral's wife" duo to it being a "frosty bed".
