Ladder Bed

Ladder Bed (id=oni.term.ladder_bed, category=building) is a sleeping furniture variant whose defining interaction relates to ladder use. Multiple localized sources confirm that when a Duplicant is sleeping in a Ladder Bed, that sleep will be interrupted if another Duplicant uses the ladder while the bed is occupied. In other words, ladder traffic and bed occupancy are linked: ladder use by any other duplicant wakes the sleeper.

Because this behavior is consistent across languages, it should be treated as an intrinsic interaction between Ladder Bed sleep mechanics and ladder traversal. Builders should assume that any ladder passage that will be used while a duplicant is scheduled to sleep can cause interruptions for occupants of nearby Ladder Beds.

Practical notes and placement guidance:

• Situate Ladder Beds away from through-traffic ladders. Placing them adjacent to or directly above/below frequently used ladders increases the chance of interrupted sleep.
• If you must place Ladder Beds near ladders, reduce traffic during scheduled sleep periods by rerouting other duplicants, adjusting priorities, or separating work shifts to minimize ladder use while beds are occupied.
• Consider using alternative bed types in high-traffic vertical corridors if uninterrupted sleep is important for your colony’s schedule and morale.
• Stack sleeping areas so ladder entries are controlled by doors or locked off routes during sleeping hours; any path that requires ladder use by other duplicants will wake sleepers in Ladder Beds.
• Monitor duplicant schedules to identify which ladders are likely to be used during sleep cycles and relocate Ladder Beds accordingly.

This interaction is specific: the sleep interruption occurs when another duplicant uses the Ladder while someone is sleeping in the Ladder Bed. Plan base layout and duplicant routing with that single, deterministic constraint in mind to reduce sleep disruptions.
