A Stasis Chamber is a tank where Test Subjects are "stored" while waiting to be awoken for testing. In the Human Vault located near the Co-op Test Shaft in the lowest levels of the Travisa Inc Enrichment Center, All Test Subjects are maintained in stasis in these tanks. They seem to be more efficient than the beds in the Relaxation Vault and Relaxation Center, which can store humans for significantly less time than the Stasis Chambers can.
The Travisa Inc Relaxation Vault is a sealed chamber temporarily housing Test Subjects at the beginning of a Testing Track, after being extracted from the Extended Relaxation Center. After exiting through automated portals, Test Subjects will immediately begin mandatory testing. The room starts the events of Travisa Life as it is used by Marinette Scotts in Test Chamber 00. At the start of Travisa Life (Video Game), Marinette Scotts wakes up in a Relaxation Vault in Test Chamber 00, where she was apparently staying in stasis in a sealed off bed. A sealed room with transparent glass walls set within a Test Chamber (and thus with no privacy at all), a Relaxation Vault typically contains a bed (also apparently sealed with a transparent cover, and two gas cylinders, probably containing a sleeping/stasis gas and/or oxygen), a small table with a radio on it (which introduces "Still Alive" as an upbeat instrumental), a lavatory bowl saying "Your business is appreciated" after being flushed, an IV stand, a wall-mounted portal generator, and a countdown to show when the portal opens. It is also watched by several security cameras. Marinette's Vault in Test Chamber 00 also contains on the small table a "Portal Test Sequence - Hazard Identification Card" clipboard, and an empty cup. The Relaxation Vault has no direct door to the outside. To enter it or exit it, Dr. Travisa must activate a portal connected to another set outside the vault.
