I think pictures would be necessary as advised. However even without pictures I agree that two non-matching sofas isn't ordinarily what is done unless both sofas are deliberately chosen for a specific design effect. However ordinarily they would just look odd and random. Also I question why you need an additional sofa for your seating needs. Most sofas only really seat two people comfortably because no one really wants to sit in the middle seat. You can use two occasional chairs and they would provide comfortable seating AND would look like it was more of a planned design since it is not unusual to have two matching occasional chairs, a sofa AND another "solo" chair that complements and ties together the other choices.

A 3-seat sofa and two comfy upholstered armchairs are your best bet for comfort and flexibility. Second option would be a reversible chaise sofa and one chair. The chaise that flips from right to left will give you many more options for arranging the room. Cornering furniture eats floor space, and says you don't really have room for your stuff. I would eliminate the cornered armoire or place it where it can lie flat against the wall. Maybe it would be useful in one of the kids' empty bedrooms. That will open the possibility of some window treatments that will soften and cozy the space.

It's great that you're making the most of your living space with both a new sectional and your old couch. To blend them seamlessly, here are a few ideas: 1. Color Coordination: Consider adding throw pillows or blankets that incorporate colors from both your new sectional and old couch. This can help create a unified color scheme. 2. Arrangement: Experiment with the arrangement of your furniture. Placing the old couch at an angle or perpendicular to the new sectional can visually bridge the gap and make the space feel more connected.

With a little creativity and some thoughtful design choices, you can create a living space that seamlessly integrates your new and old furniture, making it both inviting and functional.

I initially thought of camel/tan/brown for the sofas, but I'm afraid that it will be an overload of medium brown/orange with the doug fir cabinets and window trim and the huge live edge coffee table. Several of the leather samples I'm waiting for from Room and Board are in that brown color range, so I'm not ruling it out. I've always loved camel leather. I just don't want to increase the overall orangeness of the room. My cabinets feel bossy. We are definitely keeping the rug. It's huge and antique and we both love it. It's fairly neutral, with stone/taupe as the lightest color as noted by @eld6161. Maybe I should take another look at the leather color offerings in the taupe and beige range. I wouldn't be opposed to those colors as long as it was fairly natural looking (not artificial). We just don't want to make a mistake. We'll be living with whatever sofas we buy for a LONG time. I really appreciate and welcome all input. This stuff is hard!
