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.

Hi Nikita, First and farmost, you have very beautifull coushion on sofa, from where you buy it? You can check the videos of Small budget Big makover first session series in youtube. In One such house in Gujarat, Muninder and Bishakha coloured the old sofa set with whtie (The sofa is like yours) and changed the centre table. Interestingly, the family also had your kind of sofa set and they also want some modern style. The architect duo did not changed the sofa, just changed the colour. Yes I found it in youtube. it is the house of Setu Upadhyay. the link is https://www.youtube.com/watch?v=85GNhyLeVnM Another suggestion is that you have many tables on the room. You can drop few chairs and opt for a single centre table

Okay, do you have any theme or colours in mind. Like do you want a modern look, ethnic look or a mix of both. Which colour family earthy tones like reds and browns or Mediterranean like whites, blue and green.
