I shopped on homefurnituremart.com and got a Parker House Cityscape unit. However, Parker House makes some very large configurable units as well.

wonderful room, only a few small tweaks, could really help. you do need a larger stand for your tv, can you pull it out of the corner and put it against the wall? either to the right of where it is cause i can't see there. or where the shelves are or where the chair is. i think you should pull the chair out anyway, not all your furniture needs to be against the wall. here are a couple ideas i would keep the cute little marshalls table and replace one of your side tables with it, it will give you a touch of variation. here are some other choices for coffee tables, i buy reasonable things, if you use your computer, you can hit the key and it will take you to the company. you seem averse to color, but white on black is too loud. let me try some other ones. put one on your chair and they will all match. i have others, and others in a different color if you like all should be under $25.

But to your point grapefruit, if the tv was in the bar area, the seating would be awkward for a family of 5. That’s why I’m looking for a solution that can add more comfortable seating for tv watching and possibly replacing current furniture with a sectional.

I would definitely wait until you've finished painting the room and hanging curtains before painting that TV stand. It looks like the visual weight helps balance the dark sofa. And the warmth of wood and leather looks really nice against gray. If you must paint it, white could work.
