One idea

All good in concept, but my experience is none of those are very comfortable either as beds or as seating. I'm hoping someone knows of a specific brand that is really comfortable.

Widen the doorway. It isn't a tough job for you to do or that expensive for a carpenter to do it.

My husband did it by himself in our cottage. Then he made two panels to fit the wider opening.

Did you previously have a sofa in the space? Will any sofa fit through the door?

It’s a newly built house.

I would think about doing a built in wall unit that houses two murphy beds, twins or fulls on each end and a lower built in between them that a TV can go above. Then I would look into modular sofas specifically made to fit through small doorways.

Not an option to widen the doorway. Laundry room on one side and garage on the other, creating a hallway. Windows are also too small for furniture. I don't believe a typical assembled sofa would fit through the hallway and door.

We had the same thing happen to us, and brought it in through a window. It was on the second floor so we used a pallet jack to lift it and had to remove the window. Got it in though!

Macy’s has some comfortable/not too expensive sofas. i helped put one together recently - it came in 2 boxes. i know they have sleeper options although no idea if the mattresses are comfy. we have guests that prefer to sleep on the macys couch over the ikea sleeper in office though! we have a fancy double camping mattress that we will put on the ikea one if we need to comfortably sleep two.

ETA exped camping mattresses are quite comfy but not cheap.

The sofa that does not fit is from Macy's. We got the Radley queen sofa sleeper. Maybe there's a different one at Macy's. The one we got was fully assembled, so too big to move through the hallway and door. Something needing assembly would probably work.

Pretty sure it was a radley we put together lol. no idea why it wasn’t assembled. it actually came with mismatched parts so had to be sent back and next one came assembled. at least without the sleeper part it was super easy to put together and take apart (we realized fabrics were different after set up so we got to do both of course!).

We had a very large L sectional that was also a sleeper sofa. The backs came off as well as the individual seats separating. We got it into our basement, that had an awful angle to get around, with no problem. Our computer desk counter, on the other hand, had to go through the window.

I just purchased the Burrow Nomad for our TV room. I do prefer firm and it is that, but there are other styles available. Two advantages are modular and very quick shipment.

Did they tip the sofa vertical when trying to get it in?

If you’re in a large metropolitan area, look up Sofa Doctor. It’s not cheap but they actually cut your sofa and put it back together. My daughter had a sleeper sofa cut in two to get in the basement. She actually did the same one twice!

If you own the home, I would figure out a way to make the sofa fit. If you popped off the doorway trim, would the current sofa fit thru?

I like Wall Beds. My daughter has one that’s built in with shelves on either side. It’s not cheap, but easy yo use and comfortable. Another option - blow up beds. We’ve used those a lot and they’re really comfortable if you get a good one. The best ones are bed height, and I usually had a mattress topper on it. Surprisingly stable and comfortable. I wouldn’t dismantle or physically change my brand new home just because of one sofa. Good luck to you!

How wide is your doorway? How wide is hall. Draw a sketch and put measurements on it. Can’t help without knowing more specifics.

We had to remove the entire door and jambs to get a sofa into our basement. With prehung doors and stained trim (no paint touch-ups after), more do-able than one would initially think.

I would ask macys if they have assembly instructions for it. i really think they are all shipped flat packed then assembled for delivery. the instructions were fairly straightforward - like putting together ikea furniture.

I'd do a twin daybed with a trundle that pops up. How wide is the door?

Alternatively, you could build in a custom daybed:

Can you take the legs off? if you can, it should go through the door with it stood on one arm. It not daybeds are very comfortable to sleep on, but depending on your height, they may be too deep and high for a comfortable couch.
