In a narrow bedroom, turning every item sideways is not a strategy. The three anchors below keep the 2400 mm width visible and make the circulation compromise explicit.
Quick answer: The 2400 × 3600 mm narrow-room records place a Twin bed with either a long-wall route, an end-wall work zone, or linear storage and a work nook. They are designed for different daily patterns.
Geometry first. The narrow anchor is 2400 × 3600 mm. A Twin mattress may be about 990 × 1905 mm in these records; bed frames, chair pull-out and door swings consume more than the mattress rectangle.

What changes between them?
Long-wall bed protects the primary route, end-wall bed gives work a distinct zone, and linear storage keeps the middle legible.
Trade-off: The work-zone version narrows one approach, while the storage version asks you to keep the central route disciplined.
Before you move anything
Fixture positions are the records’ assumptions. A real radiator or inward-swinging door can change a strong match into a review-required condition. Measure the outside of every bed frame, desk, wardrobe and chair operating zone. A mattress preset is only an anchor.
