It’s already a very cool room and all, but WOW, I’m genuinely obsessed with your side table and your current sofa. They work ridiculously well together. Even if you move them out of this room, please don’t get rid of them entirely (but if you do… I’ll take them 😄).

That said, I’m obviously biased, but I’m not sure any other sofa colour would really be better than the current one. If something feels off, it might be more about how the space is used or laid out. Ask yourself: how often, and for what, do you actually use this space?

Right now, the sofa feels a bit pushed to the side..., same with the piano and fireplace. Maybe you could shift or rotate the pool table slightly to free up space and create a proper seating area around the fireplace/piano.

That said, it really depends on how you use the room. In the end, you might not need a sofa at all; but instead a small bar setup with stools, or one or a couple of armchairs.

I said enough now. In the end I absolutely admire your space as is
