The couch doesn't seem to go with your other pieces, although the photo isn't really that great. Have you considered a slipcover?

Odd assortment of furniture, are you making do or willing to eliminate some pieces?

Sage green would make the area warmer, more inviting, & would tie the area together. A good-sized rug or piece of carpet would help, too.

The couch is a pretty pattern but the pillows don't work with it, you should have solid pillows. The chaise couch is too modern looking to go with the printed couch. Is there another place where you can use that?

Get a SLIPCOVER. In a pretty solid. Don"t decorate around it.

Have to ask about what's under the leather chair

Does it have upholstery control issues? ;-)

I can see two options here. Go eclectic on that room's ahem:

Or slipcover.

Well, or replace all.

A sofa like that, you go hard or go home and you have to be willing to make it Work. At this point in history that is a design statement, are you willing to make it a positive one?

PS I love the sofa. The other furniture is doing it no favours though. Anything that can change here?

I think that is a great little floral couch that can easily be worked with. I would first eliminate the patterned throw pillows. I would replace them with a solid color that has texture instead. Then, add in a large neutral area rug to tie all the furniture pieces together. I would also replace your floor lamps with something less modern and harsh against the organic aesthetic of the couch.

Knitted throw pillow

Lamb fur throw pillow

Breuer throw pillow

Ok, one more. This is more subdued and also similar tones to your sofa.

The grey picks up the golden brown nicely here. Your grey chaise isn't quite getting it for you sofa, I'm sorry. It's a little too blue.

Working off of a print can be a challenge but it's a fun one!

Pulling some of the colors from your sofa, add some textural solid colored throws and pillows to accent your seating. You can do a little print too, just look for prints which are a much larger or much smaller in scale than the print of your sofa. A nice round ivory area rug and abstract wall art above the sofa will help ground your space.

Pull the same accent colors- like the blue, ivory, and honey color from your sofa over into your dining area- table runner, vase, dining cushions, candle...etc.

Rug idea:

Happy decorating!!!

The pillows are fighting the sofa. Move them to another room. Find pillows in the same colors as the chaise or chair to tie everything together.

Alternatively, if budget allows, buy two chairs that match each other in one of the colors from the sofa.

I actually like the sofa.

Neutral Couristan of jute / cotton. Your sofa is for Autumn lovers. :)

I'd try one color and repeat it in different tones. Green a bit brighter than the chair for starters.

5 x 8' rust-colored jute for 108.

Cotton tapestry 26 x 54" for $74. Hard to tell - wheat field.

Horizontally, 2 Asian panels - find where you can.... any 'architectural' element might by worth a try.

It's unfinished. I wouldn't add too many warm pieces [or much dark brown], or it's the 70's all over again. ;-)

This medium warm brown seems like sofa's color - you can use rust/brick/terra cotta also? and that'll go with the forest / hunter green chair.

Eugenia, is this a rental? How long are you in the space, and what sort of budget, if any, do you have?

Wow lots of ideas! Solid pillows on a floral sofa. Easy.

Sort of your colors - 22" tall - different enough from the floral. $107.

I'd ditch the sofa. It just doesn't work. You will eventually be able to find and afford a sofa that does, but this one is not it.
