I have a room like this in my house. It does have furniture though. It's a sun room and it's all knotty pine with big windows looking out to the lake. I wouldn't rip that wood out for the world so I work with it. I have a poppy colored chair and 1/2 with a storage ottoman and a small side table next to it. I have Persian carpets, a low round table in the other corner, lots of pillows, bamboo shades, several plants and a couple leather poofs to sit on. Those are SO popular and easy to find. I have a hookah too but it's never been used. It's huge and really beautiful red, gold and white although everyone wants to use it when they see it. I get most everything at World Market and they have good prices for home decor. Think colors, lots of different textures and relaxing and mellow but I wouldn't forgo furniture. At least some, even a daybed or a futon instead of a couch or chair would be nice.
