I just moved into my new home and the main floor has a small open concept living/dining/kitchen in one room. I'm struggling with furniture arrangement and size in the living room as well as color scheme.

1. I want to add a rug and I'm thinking a rust/antique type rug (something like: https://www.amazon.com/gp/product/B00PNRFXZM/ref=ox_sc_act_title_1?ie=UTF8&psc=1&smid=ATVPDKIKX0DER). But I'm not sure if the colors will work.

2. I just bought a new couch that it taupe and I really love it. But I want some chairs in the room as well. Not only for more seating, but specifically comfort. I don't want to get a couple tiny accent chairs that I can't curl up in with a cup of coffee. But the space is small, so I don't want to crowd it with big chairs either. So I'm not sure how to proceed. I bought some club chairs (see picture) that I put in front of the fireplace. They seemed to be too much though and weren't comfortable, so I ended up returning them.

3. I also intend to redo the fireplace with stone and reclaimed wood mantel eventually (like: http://www.sweetnumber9.com/2013/02/dreaming-of-stacked-stone.html) but not all the way to the ceiling.

4. Lastly, I don't want to over crowd the space with furniture. I want to keep it slightly open for a kid on the way. So enough space for running around and not running into coffee tables and bookshelves and chairs in the small room.

Any help is MUCH appreciated because I'm at a complete loss here. I've scoured the internet for hours for looks, but I just can't figure out this specific space. I've never had a room that opens directly into the kitchen.
