TV is mounted right in the traffic path from the front door. I would have put it where the bright pink picture is. Worth the expense of moving TV connections and repairing the wall if you own the home. Your coffee table is too big. It should be 2/3 of the width of that seat section of the sofa. Are there actual records stored in the record cabinet? I might think of storing liquor there so I could eliminate a piece of cabinetry. You could replace 3 pieces (liquor, record and TV piece) with one long piece for that wall above the dog bed. Let it do triple duty. Sell the other pieces on Craig's List and get a new coffee table. Eliminate the end tables; they aren't needed if you have a coffee table. Or you can eliminate the coffee table too and just do some "C" tables. Improve the view from the entry, and find another place for the kitchen trash can. Wall hung items should center 5' above the floor of hang 5" above furniture. Here's a chart for correctly mounting the TV. Sofa can be turned to face it with its back to the window. You can pull it forward for best viewing and add a sofa table behind it.

IMO first replace the floors that will give you a bit more visual space , As for the TV I love Ikea Besta for this purpose it can be configured to look custom the TV height is a big issue and the center of the screen needs to be at eye level when you are seated so anything you put on that wall has to do that.This is just one idea but you coulld do something where the TV and staorage and display could really make use of the that whole wall.

I've looked at so many companies.... Albany Park, Rove, Pottery Barn, Room & Board, Interior Define, Six Penny, Maiden Home, Arhaus, Article, etc. It seems like quality wise, Maiden Home is the way to go, but I can't find a sofa that comfortably seats 5 people without someone sitting in the crack between cushions. The Sixpenny 150" u chaise sectional would work, but I'm not a fan of slip covers and it doesn't seem like it would go in my space. Room & Board has a reese curved sectional that I could build that would fit the space, but I don't know about the quality. The same goes for Interior Define, which has a lot of mixed reviews.
