looks like a good set up but the chair should not be lined up with the couch turn it to face the love seat or angle it to the tv. the blue cabinet is nice but not in front of the window its too big. love the color though. should have a low console under the tv (maybe floating attached to the wall because of the heat vents)

A photo might not show actual color....but the hotter, saturated blue sticks out: not soft or understated like the pretty creamy walls with greys and teal...mix those.

Ah, the furniture salesman talked you into buying the set, eh? Too bad. Well, we can make it work.

After you turn the chair to face the loveseat, pull the ottoman to within 18" of the sofa. No one can use it where it is.

I agree that the sideboard really needs to go elsewhere, a dining area, maybe?

So far, you've made really nice choices. The room just feels unfinished because of the big bare wall. I see you have a dust-catching ledge on the wall. You could get rid of it, if you want. In any case, I'd probably get a very long media console for under the TV, and then do some art groupings left and right of the tube.

You might try moving the blue cabinet to the other end of the room under the window with no drapes. You also might want to add a few small end tables near your seating. Then try putting the single chair near the window (with a small side table) at a slight angle toward the TV.

A fun accent table can add some visual interest to the room (everything is very square and blocky right now).

We might try a TV console under the TV and perhaps some plants in the room to give it some green. Here are a few of our designs for guidance.

Good bones, but no meat on them. The tv seems to be the main point of your arrangement...sad. Turn your furniture inward so people will be able to have an actual conversation. Move the tv lower so that it is at eye level to a seated adult, but don’t turn it on unless friends are there to watch the big game. Add one more accent color: maybe coral or orange. Add art, and then add some more. Don’t build a gallery, but display art which you find beautiful or interesting. Put a couple of them on the dust ledge. Hang the rest. Hang some on each wall. Hang them at different heights. Put three pieces flanking the tv, two to the right, one to the left. One or two can be as large as the tv. Vary the sizes and topics. When you travel, buy a piece of art. Nestle it within the clothes in your big suitcase to protect it. Find some art at local art-and-craft shows. Art comes in different forms and different mediums. Maybe you will like modern art more than traditional art, abstract more than representational. Collect slowly and hang something in every room, the hallway, the kitchen, the laundry room, even the bathroom. Art framed with glass is good for moist places.
Okay, I got carried away. Color and art will add life to a quiet room (I almost said “dreary”, but you have nice furniture). Make your home a place you like to be and a place you like to share with friends.

This looks like a hotel lobby everything matched with no real life to the space . Rooms need to have contrast it is nice enough but honestly take the chair away from the end of the sofa thats just odd , lower the TV get a cabinet for underneath it move that choir to another space anf get one in a pattren with colors from the rug and also use some color from the rug for accents. You need more lighting like at least a floor lamp ideally an arc one to put some light into the center of the space and go shopping for some art please.

Grover gave you wonderful advice about configuring the furniture and adding interest to the TV wall with a long console. Here's a similar idea with an accent wall color.
