As you stated, something is definitely not right. The seating is set up like a waiting room. The styles of the furniture do not work well together. On the other hand, your area rugs look like very nice quality.

First and foremost, is what do you want to do in this room?

Once you decide that, you measure every wall, window, door, opening. Draw it in pencil on graph paper, 6" to a square. Layout is first, then you decide on style, color, etc. You also need to consider lighting for the space.

It looks like a fairly large room, so several groupings would probably work. But until we see the dimensions, it's all just guesswork.

agree w/diana. sorry, but the way it's laid out reminds me of an old folks home. everyone has their little section to visit or have tea.

the 4 rugs, the older style furniture all pushed back against the wall, diff tables and chairs.

what do you do in this room? it's huge. how many people live here?

what kind of style do you like?

you need some art. LARGE art not 3 tiny pictures.

the drapes need a rework. they're all scrunched in too closely.

Everything in your first two photos is exactly the same height, with nothing (very little) on the walls. Eyes like to bounce around a little…background, foreground, up, down, left, right. Your room is all horizon.

Current American style trends would prescribe a different, more broken up into smaller groups furniture arrangement but I believe lots of seating around the perimeter is more typical of middle eastern living rooms. What is your preference and goal?

What geographical region are you in? Many styles and preferences are local.

I agree with comments posted above - you need to (i) let us know how you want/need this room to function (e.g., is it the main tv viewing room?), and (ii) provide a scaled drawing of the room with all measurements (walls/windows/doorways/etc.).

It is a large room - it would look better if distinct "areas" were set up within the room.

I think you just need art on the big, blank walls.

Are you willing to let a lot of the furniture go? Rugs are lovely. But, too many in one area. Each rug should be used to make a zone.

I'd start the design around the French pieces, including all others that relate. So, just about everything in your last photo I would keep, except the ceiling lights

As for the rest, although I can't see every little thing, I would sell, donate, ask friends if they need anything.

Window treatments gone.

The room needs to be painted. Because of the size, the different moldings and finishes, and the expanse of ceiling, consider a color wash, painting walls, ceiling and trim the same color.

Now you are working with a blank slate.

Choose the largest rug and group furniture around it, not on it, just the front legs.

TV viewing should be a separate area, and if you are set on a sectional, it could be positioned with back to the rest of the room. The back the sofa, with another rug, will give another zone. Sectionals can be awkward. Have you thought about a shape like this one?

A note about rugs. Be certain they do curl, bunch, or otherwise cause a trip hazard no matter the age of the occupants.
