I'd get solid chairs to replace the peach ones. Take the light color from the rug and use that for new chairs. Peach is very dated.

I don't mind the peach, especially with the navy. I'd get rid of the striped chair though. The rug is too small and the coffee table is undersized too. It's also too traditional for the more transitional furniture. I'd get rid of the gold-framed picture too. The frame is too heavy and formal for the room.

I, too, would put the sofa on the short wall; turn the rug and coffee table horizontally to the sofa. Angle the two chairs to face the sofa with table between.

The glass lamps…they are too short…try put them on some books...

Could you take a picture of the wing chair wall and the opposite end of the room?

I can’t facebtwo chairs to sofa because there is opening to dining room. Only have long and short wall to put furniture against

furniture doesn't have to be against walls and often looks better floating

I tried to keep the arm roll styles similar to your blue couch, I think that is an important feature you are going to want to remain constant with your furniture selections, they are both also in the tufted style you like. One white which complements the room and would do well with the pops of white and go great with a blue pillow and be able to continue the white when placed on the (my right) side of the room. The blue and white patterned sofa I feel would go great between the blue sofa and white chair and complement your rug, a blue or white throw would compliment it well. These nice white ladder shelves are corner shelves which would be better than a regular one so you can see it from all corners of the room and look nice with your white lamp shades. Good luck and have fun!

Repaint with Benjamin Moore simply white for a nice warm tone. Rearrange the paintings and get two of the chairs and put them opposite and the couch were it is. And keep the coffee table and get a bigger rug.

Can you put the couch where the chairs are and the chairs across from that? Coffee table in between? Maybe add some pillows with blue detail to the peach chairs

Can you swap the sofa and the peach chairs and take another photo?

Here are some pillows that tie peach and navy..

Just now your furniture looks like it politely enduring each other's presence until it can graciously make its exit.

Though I understand that you don't want to block the doorway to the dining, I think you can still achieve a more compatible arrangement by doing as suggested above:

-place the sofa on the short wall

-place the pink chairs (I see dusty rose, I think others see peach) at the window

-leave the wing back chair in relatively the same place, but pull it in to float in the room. Angle it to face both the sofa and chairs. To find the right spot, draw and imaginary line from the right edge of the sofa (in its new position) out into the room, and a line from the left edge of the left hand chair (in its new position) out into the room. Where the two lines meet, set down the wing back.

-regardless of whether you try out a new arrangement the coffee table should be 18inches from the edge of the sofa.

Ps I like navy blue and peach/pink/blush tones. I think those colours have had a nice long rest and can come back anytime as far as I'm concerned!

I always seem to go back to those colors even though they were very 80s!

It looks like you need a larger rug, try moving the blue sofa to where the peach chairs are now.

The try this layout:

I would recommend a layout like this for your room.

I agree with Beverly’s rearrangement and the larger rug...actually many of the comments. I’d add that if the peach on the chairs is not for you (I think it’s fine), you might consider having them recovered. They look to be quality pieces and if you change the backs and take off the skirts, they’ll look updated, but maintain that classic line.

I agree that the picture with the heavy gold frame should be replaced with something more modern and that the rug should be larger. The chairs suggested by other posters look great. I think if you do those three things you will be much happier with your room. Good luck.
