I have a LR (21'3"x12'). One wall has large windows and a recessed FP, centered. One wall is a 12' glass door with views. Opposite the FP wall is the stairwell wall, which is solid wall (not railings.) This seems the best wall for the sofa, but this wall is not centered with the FP. I want a long sofa (9', 3 seater) ad rug, and then 2 lounge recliners facing the sofa at angles. Where do I put the chairs-- centered with the FP or the sofa/rug. (If it matters, the ceiling is vaulted upward from the FP wall towards the stairwell, and there will be no TV in this room.)
