Living-room sofa placement should support conversation, viewing, daylight, heating clearance, window operation, and a direct route between doors.
Quick answer
Place the main sofa from room function and measured circulation, then adjust secondary chairs and tables around it.
Keep the passage outside the seating group
People should not squeeze between a sofa and coffee table to cross the room. Check the route when seats are occupied.
Use support without blocking openness
A wall is not mandatory; a floating sofa can define zones when there is adequate clearance and a stable visual backdrop.
Coordinate screens and windows
Test television glare, reading light, curtains, and views at different hours. Symbolic symmetry should not reduce comfort.
