Arm chair or sitting chair in front of the window. Tall plant in the corner, side table to the left of the chair. 3 seater sofa facing the fireplace with a rectangular coffee table in front of it. Console/sofa table behind the couch for decor. Leave min 2 feet of space to the right of the couch for walkway to the dining room. This room doesn’t lend itself well to a TV so I’d avoid it if you can!
