Can you put the chaise part up against the wall? It would open up the sitting area to the rest of the space. You could also add a rug for some texture and warmth ... the room is probably a bit loud too, with tile floors and empty walls.

I agree with several of the Houzzers ideas previously presented that suggested 3, 4 or more spaces within that large room: Here are the suggestions 1. TV viewing area 2. conversation area: one large one with two sofas plus two chairs, and perhaps a second smaller conversation space further away with two comfy chairs and a side table between them 3. music space 4. library (this can also be the smaller conversation space mentioned in 2. above) or a more serious homework space if you place a table there to work on and have plenty of outlets and wifi connectivity cabability 4.game area with table (for cards, chess, etc) or pool table or ping pong or whatever is your kind of game 5. a tea cart 6. a wet bar I like the image of a lodge lobby, or the first floor of an old-fashioned dormitory where we did our entertaining because no one was allowed up in the rooms.

What Beverly shows you works well and looks terrific to start. The only thing I would change is the TV - change it to what katinparadise and rthawk described. The console your TV is on now is contributing to the visual clutter - and their solution will eliminate that and clear up that corner area. Your room looks so much better with the sectional moved to the long wall. That sofa table Bevs shows really works with that end of the sofa - so you can add a lamp and make the room even more cozy. I love the curtains Bev shows and the way to hang them so they don't crowd the window (high) and full. Good luck, have fun with your new room! You are on the right track OP.

a couple more thoughts... a ceiling light fixture will help and bring some interest for sure. have you thought more about one? art absolutely will help and so will pillows. I also think you might want to consider new inserts for pillows if you can. and larger size pillows like 20inx20in, not sure how that translates in com, but large size pillows will help. consider the size of the insert one size up from the size of the cover so it fills out the pillow and makes if more fluffy. if you get feather down inserts i would consider that too. thought I would share a couple pics that show how just a few additional features will make a difference. I like the idea of a couple large pillows on the floor too. I would style the coffee table a bit too
