I like this soft gray color in your room. Are you looking for a specific set of furniture or just a color direction? The three photos in your ideabook suggest you prefer a more modern style.

I would start by creating a layout and a rug. Your room is very neutral and almost any sofa would work in it.

Lovely room. I see this scheme for your room. Keep it light and simple, starting with a wool/jute rug in the same tone as the floor. Adding a soft green/blue sofa, and stronger colors in the art, would be my choice.

The window treatment @ffpalms recommends is perfect.

I love this look.

These drapes paired with woven wood blinds would look great in your space.

I am interested in contemporary/ modern style. However, I have a gifted Persian rug,so a transitional style might be a better choice.

Do you have a photo or the rug, or a description of the colors?

What do you think about these sets?

Thank you so much for your help

Could you please send me a link to your offered leather sofa?

I was not able to copy the link to the sofa, but it is from Wayfair.com.

Here’s a beauty in REAL leather from artemest.com. Pretty pricey!

Another leather to consider, comes in slate.

May be in beige or toupe

Wish you had mentioned the rug earlier.

I would stay more traditional with a Chesterfield sofa and an oval glass coffee table..so you will see the rug.

Consider this color, It's called mink...warmer, almost in the purple family, but with a distinct brown undertone.
