The Story Behind This Bed
Bedroom lighting is usually decided last and should be decided first, because most of it depends on dimensions only the bed maker controls.
Bedside lamps. The bottom of a lampshade should sit roughly at shoulder height when you are sitting up in bed - too high and the bulb glares into your eyes, too low and it lights the table rather than your book. That height is a function of mattress thickness plus side table height, which is why we dimension side tables after the bed and mattress are specified.
Wall and reading lights. These must be positioned before the headboard height is fixed. A tall carved headboard will simply swallow a wall light installed at a standard height, and moving a wired point afterwards means re-plastering.
Integrated lighting. Concealed lighting can be built into the headboard or beneath the bed base as a soft night light. Both need wiring routed through the frame at manufacture - it cannot be added later without dismantling.
Tell us your lighting intentions at the briefing stage and all three problems disappear.
