Before investing a lot of money in changing major pieces, reconsider the placement of what you have. Then you can better see what "fits" and doesn't.

Is that light colored corner on the right a corner of a hearth? Or is it the corner edge of another rug in an adjoining room and/or this same room if this is a living/dining combination?

Where is your television?

Your art all seems a bit high. Any art or grouping of art should have its center approximately centered face high while you're standing looking at it ... not looking up toward the ceiling.

While a floor lamp in the corner behind a chair can provide light, so many lights tend to glare.

Have you consider a pair of square side tables or cabinets, each with a tall thin lamp and medium sized white shade for light for reading?

Before moving furnishings, you might first want to invest in graph paper and draw, to scale, the room and all its fixed features -- windows and doors, etc. That is the easiest way.

Alternately, I suppose you could invest in some plastic with felt sliders so you can more easily move your furniture about and/or, get some help moving items.

If that is a hearth, are the windows and ?hearth? centered with each other or are they off centered? If not centered, you may need to consider making that alignment irrelevant by placing your sofa not facing it

Once the sofa and windows and the hearth or other are already aligned/centered, then ...

move the sofa forward so the front feet of the sofa are resting on the rug.

Bring forward and turn the smaller chair on the right so its back is "against" the exterior wall no along the left of the chair so the sofa and that chair are at a right angle.

Bring forward and turn the large chair on the left so the front of it faces the front of the other chair or you could leave it at a bit of an angle.

You should have a small space behind/by the larger chair on the left to create a small children's play area.

Are the red panels and throw an effort to add a bright cheery color to the room? There is no art that also has a bit of that color or any throw pillow. You could consider adding a couple more small splashes of red if you like that color in your room.

Do you need the sofa where it is to face the television so the entire family can watch and need to keep the tv at a specific location because of where the cable hook up is located?

and/or

Have you tried your sofa facing a different direction?

You might want to be on the lookout for a larger rug you like that is within your budget.

You might also want to be on the lookout for a pair of small storage ottoman or coffee table.

Do wait until you make some decisions on how you want your furniture placed or if you want to change/replace any furnishings before making any purchases. Know your objectives so you don't end up with purchase regrets.

Do you own or rent this place? Can you paint or change the ceiling? All the items & groupings on the walls should be centered 5' above the floor unless they hang above furniture, in which case they should be 5" above the furniture. I like your blue patterned drapes, but not the rest of them. The puffy, man cave sofa looks like it has seen its best days. Do you have the budget for new seating and a new, larger rug that picks up on the drapery colors?They don't have to be brand new; I've found some real gems second hand. A 3-seat sofa and two upholstered armchairs are always in style, but they need to work with everything else.

Here's a direction your could work toward. the drapes remind me of yours.

No one sets their furniture up in one line across a wall like yours. You have a great room shape. Set up the furniture so people can see the TV and converse with one another.

Your room requires a larger rug. Though you don't post the TV wall I'm assuming that the 4th wall holds the TV. I realize that every seat is a recliner, but the room needs end tables and a coffee table for entertaining. The coffee table can be on wheels.

Play around with the layout of what you have (both what’s in the living room now, or swap out for chairs elsewhere in the house). Live with it awhile. Do you like the flow? How does it work and make you feel?

A photo of the other sides of the room would help us. Without knowing if that's a fireplace or a rug with a dining area, we don't know if we can arrange furniture there. How about these:

A good place to start would be to get a larger area rug to fit the size of the room. Then, you can try out different layouts with your furniture. See what that does for the room and go from there.

Until you can figure out what you really want to do with your room, consider buying either of these inexpensive rugs in the largest size

I think the floor lamp you have would look better on the other side of the room. But after that, get another floor lamp so you have 2

Your room is a fair sized box that can be made into anything you and your family want it to be without spending a lot of money. Decide what colors you like, what kind of seats you want for watching tv and spending time together. Draw up a plan.

I would start with a new sofa. This one is very inexpensive. It may or may not last forever - but the reviews are very good - and it would transform your space.

And I would also do new drapes. Simple. Like this linen/cotton blend.

Thank you all so much ! ive done a few changes already, im gettin a tan love seat out of storage tomorrow and putting it on the right side where that smaller reclining chair is . and am going to get a new rug soon, heres the update sorry for the mess, 3 small children! lol also, will share picture of whats on the other wall

also, going to move around the wall decor and make them lower, will post update , thanks !

Its a little dark on the left side now, any suggestions what type of light and placing?

Thinking about putting something like this in that corner where i drew yellow, and scooting the chair up foot towards the center ?

You could get slipcovers. Great way to change atmosphere without spending a lot of money and they can be washed.

I would swap the chair and the loveseat. Put the loveseat under the far window and the chair closer to couch. You can keep that angled but pulled forward. Can you use the rug in another room? The rug should be more rectangular and become more a part of the conversation area. Right now your seating looks to be all about keeping an open area for kids to play. I wouldn’t buy a book shelf. Look for a ottoman to put in front of the couch that can be used as a coffee table but also kid friendly when the kids want to put a toy on it. That could be square and big enough so the people sitting on the couch and the loveseat can reach it. Make the curtains match on all the windows in the room. The red curtains seem out of place. Take the blankets off the backs of the couches. You can leave them, I would just fold them up smaller and drape them more. Once you get your rug find some throw pillows that compliment it. Lower the pictures. In the left corner you could make that a kids play area, have a toy chest, so they can keep their stuff picked up when they are done playing. Believe it on not, they do grow up so fast and then you will miss the mess, but only for a second 😉😂. It’s a fine balancing act with littles.

I see why you feel the room is too blah. Is this a kids play room or a family/TV room or a grown up entertaining room or all 3? The room windows should let in lots of natural light but the drapes are shutting it all out, making it depressing. Do you need that much privacy and darkness? What is the white thing on the floor in the right hand corner? What MUST stay in the room and what can go?

Here’s an inexpensive floor lamp for the left side of your room. Won’t get easily knocked over, no glass that could break. Might look nice with a tan love seat

I think your corner unit is fine but put some real distance between the huge chair and the corner shelves. If you add the corner shelves, a different floor lamp for reading might be better than a tripod

Someone suggested slipcovers for the seating for a fast big impact to cheer up a room.. Sofa and chair protectors are often easier to find in the right sizes. they often look better too. It’s not hard to move toward a boho look starting with these and adding plants and the right rug

I would not buy that corner bookcase for two reasons: 1) it will collect stuff that needs dusting (and potentially become a dumping group for daily random stuff ) 2) the money would be spent towards more impactful decor such as a larger rug or wall art.

You've gotten good advice in this thread. At first glance, my thoughts were:

-remove the curtains (I see 3 different types? See how the windows look with just the blinds. If truly too bare, get light coloured panels.)

-larger rug (is the current one square or rectangular? If rectangular, turn it the other way and scoot it under the sofa)

-move the artwork down a couple of feet (or consider replacing with larger, more impactful pieces - you have kids? Commission them for pieces! You decide on art medium, size, colours and types of paint. You can frame them inexpensively. Heck, buy some inexpensive framed thrift store art they can paint over.)

-get end tables and table lamps

Your budget and additional good quality pics of the room will garner you more detailed suggestions.

ETA: You're getting a new rug? Let that piece inform your colour palette for the room. As I said, lots of great advice in this thread. Make sure you have a furniture plan (on graph paper as mentioned upthread) and a colour palette decided before you buy more items for the room. A plan ensures cohesion and functionality. Speaking from experience, a room furnished without a plan results in a hodgepodge of stuff in a room.

If you're changing your floor lamp or adding another, consider a lamp/table combination unit or a floor lamp with a shelf or two within it. Do make sure the lamp you choose is a sturdy one ... some I've seen are not.

If/when you hang/rehang art, it would be more easily visible at eye level for the average person rather than high on the wall.
