The space has a lot of hard lines in the fixed elements, so this is a nice opportunity to bring in something curvy. Aside from the floors and fixed elements, it doesn't look like there's any wood in the space, so I'd choose that as a material choice to incorporate new texture (I'd opt for dark, like walnut). Depending on your storage situation, this could be an opportunity to incorporate storage. Your other furnishings all extend visible space (i.e., you can see through them) and so I'd similarly opt for something raised off the floor on legs, even if they're short. Target something that is 2/3 the size of the couch. Maybe it's the camera angle, but I'd move the couch more onto the rug if you're not adding more seating. More on reddit.com

Maybe something like this? But not sure if it would be too small for your space. https://www.jossandmain.com/Steelside%E2%84%A2--Cassius-Solid-Wood-Drum-Coffee-Table-X112519571-L441-K~J001133267.html?refid=GX433417082131-J001133267_1610203372&device=c&ptid=2090225421308&targetid=aud-1646023241215:pla-2090225421308&network=g&ireid=92166444&PiID%5B%5D=1610203372&gclid=CjwKCAjwivemBhBhEiwAJxNWN22rm30YWJT6yI0PVFimGvwCosK5C4Cu-irHZQPbcbl20uxE8UZmDBoCKIEQAvD_BwE More on reddit.com

There's too much sofa for this room, and it extends into the door way. If you keep them, I'd get 2 smaller staggered tables, like Parsons's tables, you have too much there already for the mass of one coffee table of either of those sizes. More on reddit.com
