Gel-filled acceleration couches that distribute G-forces across the body during high-G burns. Built-in juice auto-injectors, medical monitors, and restraint systems. Where you live during maneuvers — which is most of space travel.
Crash couches are the most important piece of equipment on any ship. When a vessel accelerates at multiple Gs, everything not secured becomes a projectile, and everyone not in a couch dies. The gel distributes force across the entire body while built-in systems inject the juice, monitor vital signs, and alert the pilot if an occupant is in medical distress. Life on a ship means life in a crash couch. During transit burns that last hours or days, the couch is where you eat, sleep, and wait. Experienced spacers can sleep through moderate burns, their bodies rocking in gel while the ship pushes them toward their destination at accelerations that would flatten them against a wall without the couch's protection.
Contoured seats filled with impact-absorbing gel that molds to the occupant's body under acceleration. Restraint harnesses lock across chest and limbs. Armrest panels contain juice auto-injectors, medical sensor readouts, and emergency controls. The gel shifts color under pressure — clear at rest, darkening under G-load. Every ship station has one: ops deck, engineering, galley, crew quarters. They are chairs, beds, and survival equipment rolled into one.
