Love the armless sofa-bench! Try using it in the center as a "cross-linking" piece between the sofa and chairs. That way people can sit on both sides of it, conversing with the sofa people and the chair people. Put the chairs where it is and use the side table from the left of the pic, or the one with flowers, between them. You'll need one huge rug to anchor the space or two smaller, and very similar ones, to put on either side of the blue sofa-bench. The other two side tables are too tall and too short for your seating pieces, so ditch them. Use your coffee table between the sofa and armless sofa (18" away from each of them.) Here's a chart for judging table and lamp heights as you'll need to work on that for balance. Please try this arrangement, and post by commenting and using the Attach Images button to add pix of the update. We'll tweak it on out from there.

Dear Crazyjunglite, please let me add some ideas for your space. I beleive that a nice combination of two curtains like the one with the blue and peach double curtains in the picture, will give you an eclectic feeling that matches to your painting. The combination of colors that I suggest is this blue with brown flares and the cream-peach taffetas, and the soft cream sheer behind. It will join all the rest beautiful items suggested by now: https://www.etsy.com/listing/163787105/blue-curtain-polyester-fabric-122-inches?ref=shop_home_active https://www.etsy.com/listing/163785041/light-yellow-beige-curtain-polyester?ref=related-6 https://www.etsy.com/listing/167660815/35-discount-for-one-pair-of-two-beige?ref=listing-shop-header-1 https://www.etsy.com/listing/167363693/ecru-sheer-curtains-fabric-118-inches?ref=shop_home_active

Leather sofas can really dominate the room and can give an overall cold feeling. I would add some earthy elements, like a wood coffee table with glass or metal. Go to Restoration Hardware's website and look at their sofa room scenes. And I'm sorry I think the art is too harsh for the room. That's all your eye goes to in the room. too overpowering. I would look for something softer or maybe a cool mirror and I would add color to the room with pillows and some colorful lamps. I also think woven blinds would look great. They add warmth and give a finished look. The color of your window treatments should contrast your wall color a bit, not match it or else it starts to look generic and blah.. You have warm walls, warm floors and the woven blinds, like Hunter Douglas brand would pull it all together for you.

HI -- The sofa and the chairs and the rug are fine together .... what I don't like is the storage ottoman . It would look better if you had a coffee table with some glass on the top and a wood or metal base . Then add some drapes in a natural linen or some with a natural background with thin black stripes or add a small black border or edging . And a lamp or two with oil rubbed iron bases and linen shades . Then some better cushions . Put matching lumbar pillows like the one on the sofa for the chairs then the red square ones on the sofa and add in a fur one or two in black .
