PROPOSED CHECKS — NO MEASURED RESULTS SUPPLIED
Date: __________________  Units: __________________
Room / product reference: __________________

1. Pillow-position control reach
Where: From each sleeper's normal lying and seated positions with their actual pillow arrangement.
Record: Place paper switch markers; note which hand reaches each function and record the proposed location relative to mattress edges in centimeters.
Your observation: ______________________________________________
Interpretation: The markers test reach for those users, not electrical placement compliance or accessibility for every future occupant.
Alternative: Move the control or use an accessible separate lamp before fixing headboard panel seams around an awkward location.

2. Function recognition
Where: At the bed and room entrance with the proposed controls represented in their intended grouping.
Record: Ask the other regular user to identify reading, ambient, and general light without coaching; record ambiguous or phone-dependent actions.
Your observation: ______________________________________________
Interpretation: An understood trial layout supports usability; it does not prove reliability of a connected system or its failure behavior.
Alternative: Reduce identical buttons, separate essential functions, or retain a clear manual route when the layout requires memorized instructions.

3. Maintenance behind the panel
Where: At every proposed driver, charging module, outlet, and removable headboard section.
Record: Have the maker mark the access method and component removal path on the drawing, including any bed movement required.
Your observation: ______________________________________________
Interpretation: A drawn access point is a plan, not verification of electrical installation or assurance that a sealed component can be serviced.
Alternative: Choose ordinary separate fittings or a different panel construction if small repairs would require destructive removal.

PRACTICAL TRIAL
1. Set the real bedside objects beside the paper controls and repeat the reach.
2. Check the reading beam toward both sleepers before approving decorative alignment.
3. Request a handover record for removable panels and concealed cable routes.

COMPARE THE SAME SCOPE
- Independent bedside functions and manual operation
- Integrated versus separate tables and lamps
- Access panels, drivers, outlets, and installation
Cost drivers: Custom joinery around multiple controls; Relocating outlets or fixed lighting; Proprietary automation and component replacement
Choose another route when: A highly integrated headboard is unsuitable when it makes essential bedtime controls confusing or places serviceable components behind permanently closed construction.

EVIDENCE BOUNDARY
These are unperformed reach and recognition exercises. Electrical safety, technical compliance, and connected-system reliability require separate appropriate verification.

DECISION CONDITIONS
choose: Choose the control layout after both sleepers identify and reach their required lights from normal pillow and seated positions without crossing the bed or moving everyday objects.
alternative: Use separate lamps and tables when a custom wall adds hidden components without improving reach, surface capacity, or independent operation.
stop: Stop fabrication if control meanings remain ambiguous, an essential action requires a phone, or replacement of a small component would require destroying the finished panel.

CCOHS: Lighting Ergonomics Checklist
https://www.ccohs.ca/oshanswers/ergonomics/lighting/lighting_checklist.html
CCOHS checks local task lighting separately from glare, shadow, and sight-line conditions. For a bedside layout, these are useful questions to apply from the reader's actual position rather than assuming a symmetrical pair of fittings provides equivalent useful light on both sides.
Scope: Workplace checklist questions inform the observation; they do not establish bedroom illuminance targets, electrical compliance, or sleep benefits.
