we just purchased a large white sectional. https://daniafurniture.com/products/mauro-leather-left-sectional and are planning on an entertainment wall with besta floating shelves something along these lines but not settled on that particular arrangement yet. (thoughts here also welcomed, this doesn't look quite right to me yet.. )

our actual floors in that room are oak stained walnut and this room is right next to the kitchen which is green and walnut, there is also a breakfast nook with a walnut table and chairs. (you might think this sounds dark but in reality it is very bright. this is a sun facing window wall type thing. we have black out curtains that we can deploy as needed.

the question is with the rest of the colors here should we be thinking glossy white with some kind of accent for the besta wall or the dark and glossy type look we have here. the black is the wavy textured black and the glossy wood tone ikea has.

the sofa is too big for this space in reality. and really dominates the sunroom. we kind of feel like it works for us though. its cozy.

and at the moment we can work with the sunroom a lot more than we can the formal living room. we need to hard core remodel that room. the only place for the tv is over the fire place. because of various arches and bay windows. the fireplace is just a problem and can't be dealt with right now. long term we will probably bring this white sofa to the formal dining room after its been done but we have no timeline for that.
