You really should move the front legs of the furniture onto the rug. Beautiful sofa, BTW. You really have a neutral palate here so you can use just those colors with the 2 pieces to tie them together or pick a 3rd accent color to use on both and then that same color with add'l accessories.

Thanks susan2494, should it be a color that pops or another neutral color?

The blue grays of the paint and rug and oranges of the sofa and floor are fighting. You need something in a pattern that ties them together. I'd try a window treatment in a bold pattern that combines the blue grays with the oranges and pull some secondary colors from it for pillows.

It's a very nice sofa!
Here are some ideas and photos.
Idea: that rug needs to be under the sofa legs, and bring them a little closer, add ottomans footstool etc to even out the space.
Pictures are attached for pillow ideas on leather sofa!

Ottoman ideas

Those pillows would look great on your sofas, myself I would be buying a couple of faux fur throws and pillows, love leather and faux fur, but that's my passion lol

It's a gorgeous couch and it's such a shame you don't appreciate it more fully due to its location and it also feels odd there with the railing. I also find the bench looks dwarfed by the console and window. Just a thought...could the console be placed on other side of fireplace, couch under window and bench by the railing and may have to turn carpet, but place front legs of couch on the rug. In regards to your original question (lol), I wouldn't add any pillows or very minimal and I might use a fake fur throw on bench or couch. Keep colors soft to compliment the rug and use art, great coffee table, lighting and accessories as your points of interest.

so op, what are your thoughts on what you have seen so far?

Love everything but I agree with susan to either move the rug back or the couch forward. Just a random question, I have never seen molding in the shape of stairs...is that what that is? Where those stairs with railings that you filled in with drywall and left the edges exposed?

Thank you everyone for your feedback. We are working on purchasing new blinds, coffee table, floor lamp etc. I will move the rug under the couch, add a faux throw with matching pillows but not too many correct?

So everyone thinks I should move the field bench?

Haha, yes, the "design" on the wall are the extension of the stairs, not sure why the previous owners did that, but it does not look horrible and it's definitely unique.

It's not hideous but It does take up wall space that could have some art on it. I have no idea how you would go about removing that as I have never seen someone do that and its not horrible. Learn/see something new everyday! And yes not too many pillows.

I am just wondering if you could do your room on the diagonal to face the fireplace? I also think the pillows with the dark gray or black and white add needed contrast. Furry throw warms up the leather. And as someone suggested industrial chic works. This room is calling for the ying yang of rustic and chic.
Btw. Love the sofa.

Yea or neh?

If you're considering an additional "accent" color, I'd find some art that you like for one or more of the major walls in the space, and then draw from that for your accent...

a couple new lamps i came across

I love your sofa! I think it's always great to over-purchase pillows. Fill your car with options and play around. I would try to incorporate colors from all elements in the room- but overall toned-down, natural hues. Sort of like a West Elm & Pottery Barn mix.

I attached some pics that were taken before it was painted, wanted to show the entire room. I'm not sure I can angle the furniture and I'm not sure if the field bench will look better in any other part of the room? Any thoughts?

It doesn't look like the fireplace is angled in these pictures so I understand if you the sofa wouldn't look good angled. It looks like you have a dining area near the kitchen.
Somehow i would like you to center rug in front of fireplace and work from there. Is it possible to float the sofa in front of the fireplace? That would be ideal. Then maybe arrange from that point? Im just guessing here and its hard not really knowing dimensions etc. It is a beautiful room and I love your floors.

You need more color in the room, add a litte gray sparingly.
