We are stuck on the completion of decorating our den. Two of three walls are glass (French doors) on one wall and all windows on the other wall. The third wall is old stone...floor to ceiling. We love the outdoors and are not comfortable blocking the doors, although we need more seating in this room. We just purchased a sisal rug(a neutral color) and we have a custom made couch (mushroom color) that is also new and a new coffee table (grey slate) Its the seating and the rest of the design we need help with. We like monochromatic... Although we do want to throw splashes of color in with accessories. We want opinions about the seating situation. We like semi modern/mid century design. We also just painted the walls "natural wicker" by Benjamin Moore. This is our room to be comfortable... We spend most of our time in this room so we are looking for comfortable seating with a minimalistic chic design.
