I completely agree, the bigger the better for the rug. There's nothing more silly than a large sectional and a small rug peeking out underneath. The picture above is a great example of how large the rug should be. I hope your sectional is a fairly light color which would look great with the white cabinets in your room.

IdaClaire I don't want to see businesses shilling their products here. Such posts, under the guise of "helpful advice" degrade the integrity and longstanding intent of these forums (and I've had many years of active forum participation). What's to stop these forums from becoming just one ad after another? Nobody wants that (except perhaps those who only participate in hopes of making a buck). Pros that offer their own products or services in response to a query have a vested and biased interest. It makes me sad that such things are even allowed here. And yes, I do flag this stuff as spam and will continue to do so. There's a lot of poor and amateur advice here on this forum, and I'm in the business going on my 35th year now. I swing by to help out when I can just in the same way I help the lady next door change a flat tire on her car. I have never got a single order off of HOUZZ that I'm aware of. But this is the appreciation given for the professional expertise and experience which is FREE? Vested and Bias interest? <rolling eyes>. My wife says "Why do you even bother with doing that? That's the best use of your time?" At least the lady whose tire I changed will say Thank You instead of telling me I'm out to sell her a brake job.

It would be better to have empty space near the slider than to have a sectional all the way up to and in front of the slider, or a sectional with a short seating side in the open part of the room to keep the sliders clear. But I agree with others that a sofa and chair is much more functional.

@Patricia Colwell thanks! Our TV is in the corner in the bottom right of the bottom picture (you can see our daughter there). We’re doing a corner fireplace there as well. So would you suggest leaving the sofa where it is and doing two chairs where the loveseat is now? Like this pic?
