Thank you!!! Maybe the the picture will give a better perspective. I’ve added two more photos below. Thanks!

if you like monotone (all that biege), i would add greenery: a few large houseplants. pillows and/or a "something different" adds pop also (piano, chest, period furniture, screen, floor art, etc).

I think the style of the chair is fine. It's the pattern on the chair that is just too much and doesn't match the calming energy of the rest of the room. I would re-cover it or replace it (sometimes cheaper than recovering) with a chair with fabric that fits in with the other seating.

The chair pattern is nice, as are the pillows, but I would mix it up a bit with other pillows. If using that printed chair, maybe different pillows completely on sofa.

The chair is nice. I could also see a style like this.

As another idea, I think a subtle animal print -

or a bold animal print

could be fun in your room.

I recommend adding a slim sofa table in back of sofa, since it is floating.

Remove the pillows that "match" the chair - remove them to storage.

When you can, shop for new pillows picking up colors from your room.

You also need some color, maybe orange from the art work.

Get a plain beige throw and toss it over that patterned chair to calm it down

a little.

Not liking the credenza with mirrors over it. Something is out of scale.

Would the shelving unit look better there?
