One more of family room

I think your table is long enough to put a banquette on one side and use two chairs on the opposite side. Would advise a larger coffee table, possibly round and mix of glass and metal for a bit of bling. Set it about 18" from the sofa for accessibility and walk room. You need an appropriate sized side table for the chairs as well. It needs to reach just at or below arm height for practical use and if the chairs angle, use a round one. If they sit straight, a square one is better. Would get one large enough for a table lamp. My choice for entertainment wall would be to build-in a tv, bookcase, storage unit picking up on the dark wood of your dining furniture. Consider replacing the two khaki colored throw pillows with more colorful accent pillows. You could do pillow cases for them and possibly match the dining chair seats with the same fabric.

Love your suggestions! Wish I had considered this before I bought the coffee table - I like the idea of a round glass table. Oh well - like the ideas for the side tables and entertainment center. Thx!
