A floor plan would help here. Is there room to have the couch and chase across from each other with the ottoman in the middle? I can't tell from your picture if you have room to the left for the couch.

If you don't have room to put the chaise opposite the couch, I would pull the chase down on that wall. Try turning it 180 degrees so the arm/back is away from the couch. Put the end table at the other end so that it is opposite the end of the couch -- maybe even positioned so that it can be used from both the couch and the chaise. That's a right off the top, but seeing the rest of the room or a floor plan would help with other possibilities.

Sorry, here are some other views. Behind the chaise (where headrest is) is the kitchen entrance. There is a huge archway to the library/dining roof at the left of the couch (as you face it). The hallway to the bedroom and the front door is at the edge of the end table at the foot of the chaise. Thanks, all!

One thought is to put chaise in the corner, angled with the back towards the corner. Then put the matching printed upholstered chairs on the wall where the chaise was, with the coffee table and lamp between the two chairs. The little cabinet that's under your tv could become an end table between the couch and chair. The tall, leggy cupboard would need to move, maybe it could go next to the kitchen door if you don't have another spot for it.

The console that's under the window looks like it would fit well under the tv and help ground it. (Or is that a radiator cover?)

There's a lot going on in this room right now. Ideally, some thinning out could be done. Are there things that are must haves and some "could go's"? It's a cool place. I like the arched doorway and nice millwork on the doors.

I also think your room is going to need some editing as well as some rearranging. I see the couch, chaise, ottoman, 2 arm chairs and 2 side chairs, a table, the highboy cabinet, the cabinet or other piece under the TV, the keyboard and music stand, the round table, the end table, another small table or chest next to the arm chair by the keyboard and something that has a top reflecting between the couch and the keyboard. And that's assuming that the thing on the far end of the room is a radiator cover. That appears to be 16 pieces of furniture in a relatively small room.

What do you need this room to do and how do you want it to function? What do you consider essential in the room, what can move to another location (or go away)? How many people are in this room most of the time? How often do you have more people and how many? And is it possible to move the TV or is staying on that wall a must? How is that cabinet being used?

Thank you, everyone! Just we two, and we have a lot of stuff. Might move keyboard into other room. Flat-screen has to stay on that wall.

Usually just the two of us, but we'll have four or five people over sometimes.

I realize I didn't address your initial question -- is the chaise a mistake? It is if you want a piece with a back or a sectional, which is what you are trying to do with it placed agains the wall. If you want a chaise to work, you need to stop trying to make it another couch and embrace it as a chaise. When I think of where I've seen an awesome chaise, it has always been away from a wall -- either out in the middle of the room or in a corner coming out into the room. It needs to look like a chaise.

Would you be open to trying pulling the chaise away from the wall and putting the couch opposite it? Or does the couch need to face the TV for you? In that case, I would try the chaise on the other side of the room. Someone above mentioned putting it in a corner -- you could try that too, but the corner by the TV means it will probably be used a lot less and the last place you sit to watch TV.

If the chaise works on the opposite side of the room, then the wall where it is now can be used for the tall cabinet, the pair of arm chairs or the side chairs and either the black end table or the round table between them -- depends on how you want to use the room and those pieces.

If that is a console table in front on the window, I would put that under the TV. You could also put the round table more into a corner with the chairs to the side -- it will take up less of the room's space. You may or may not have a space for both pairs of chairs.

You say the TV needs to stay on the wall where it is now. I would want to put it on the wall where the chaise is. It feels like it would be a better viewing spot and give better furniture arrangements. I mention that just in case working with where it is now doesn't lead to something you like.

If you haven't tried some of these things, try moving things around and see if one of them makes things start to click for you. If you need more help, a floor plan with measurements will help.

Without measurements or a floor plan it's hard to make useful suggestions.

You can get a free or very affordable design plan for your computer or iPad if you have one. Or just draw out the space and take a screenshot and post it.

Anyway, here's a quick mockup if you can't move the tv. Can you give us the basic measurements?

Can the chaise move down so that the end table can go in a new corner between the chaise and sofa?

Like bpathome said I think.

Thanks, Annette, that's what I was thinking.

I think Lascatx had the same idea, but with rotating the chaise. While that would look good, it's less practical because I think people stretch out on the chaise to watch tv, right?

if you can move the keyboard to another room and it still works for how you use it, by all means do so. It looks like you use the round table since it's next to the kitchen, so if you move the keyboard you have more maneuvering room, maybe you can move the table to that corner. Or, that handsome tall cabinet can move to that wall to balance the TV on the other side of the room.

And is that in fact a radiator cover under the window? It's cool. Can you get another one for under the tv? It really does need something to ground it.

(btw, my brother is in a vintage building where he is not sure of the original uses of rooms; my son, too, where some changes have been made, altering the room uses in perhaps an unusual way. So I wonder, was your living room originally the dining room? Does it work better as a LR for you?)

Annette's arrangement is the most workable and would look best. And yes, do a bit of de-cluttering. You've got a great pre-war apt. Perhaps sell the chaise on Craig's List and buy two smaller scale club chairs to put on that wall instead.

And yes, you need something under that TV to anchor it - a console perhaps. Curtains would also warm up the room.

Your apt reminds me of my DD's first NYC apt when she got married 20 years ago! It was a great apt and they loved it.

I just realized there is another pair of chairs and a round table behind the sofa. So I added those and moved the console under the tv. Again, guessing on dimensions but this is the general idea.

Bpathome, what you were suggesting was my first thought and what I first typed, then I was afraid the arm/back of the chaise would make it too difficult to use the end table so I may have lost that in the edit. But you also have the ottoman. I would certainly try just sliding the chaise down first -- the easiest move, so why not?

As far as moving the keyboard out of the room, I hesitate. DIgital keyboards will never have the grace of a baby grand, but depending on the use and the user, it might need to stay in the room. That's why I was asking about people and uses in the room.

This place appears to be near the same age as the first home I owed. Loved that house and neighborhood.

Thank you, everyone! Would've replied earlier, but I was ill. I'm unable to put a flatscreen on the chaise wall now; just the way the place is wired. That's a radiator cover by the windows. I am considering moving the keyboard into the other room.

I like the idea of the chaise facing the sofa. But the chaise has a left arm (arm is on the left as you're leaning back in it). Wondering if that will look okay? Would move the chaise to the bedroom but there's no room for it there. NOW I'm thinking I should lose the chaise and get another sofa (six feet long) to match the other one and have them face each other.

Intrigued by the curtains idea. The window sils are more than a foot deep; should probably be inside mounts, right? My upstairs neighbor has huge ceiling to floor drapes around the window. Looks odd to me.

Will try to get measurements up. Not in the best of health right now, so hard for me to take measurements.

If you want to try the chaise and sofa facing each other with the TV on that wall, I would take Annnette's last drawing and leave the chaise where it is and pull the sofa around on the other side to face it. The arm or back should be opposite the TV -- Bpathome was right about that.

I am generally a less is more on window treatments and like full length drapes in formal areas and some bedrooms. With a smaller room, more casual furnishings and a short, deep window, I'd favor shades or blinds of some sort, but that's me. You could have color, texture, wood, fabric -- but I'd get the room situated and then look at the window.
