I think you have some options when it comes to sofa vs sectional, but you don't want to get anything overly large. For example, an 80" sofa with 2 large end tables would pretty much block the 11' width of the room (facing the TV) so you would want to do just one end table and a coffee table instead, or two very narrow (less that 20") wide end tables.

If you go with a sofa, I think you would want to face the TV for comfort, and maybe do two chairs on either side of the fireplace. For a sectional, a smaller "L" style would be about all that could fit.

If you were my client through Ethan Allen, we would do a complimentary floor plan first, to make sure whatever options we were considering fit appropriately and didn't overwhelm the space. This would also help decide what kind of tables we would need/could fit in the space.

Formal or family?

Adding one or more large ottomans can be moved against a sectional for lounging. They can be used in place of tables.

What do we think about these options?
