I have a full size sleeper sofa in my guest bedroom. It fit through the door in the vertical position. I wanted a queen size, but there was no way to get it into the room.

Take the window out.:shrug:

Or consider one of those built in Wall-Beds, then use a smaller sized sofa for sitting

I think either Babette's or CITY Furniture (maybe both) have all of the floor plans used by the developer in their design system, so you might want to contact them, tell them which floor plan you have, and the exact dimensions of the couch, and they will probably be able to tell you if it will fit or not.

Same problem with our Vera Cruz plan. We wanted a queen size sleeper sofa, for guests, in bedroom 2 which we use as den/office but can’t make the hallway turns without going vertical and therefore limited to the door height of 80 inches. Could do a full size sleeper sofa but many of our couples relatives/friends wouldn’t fit in that too good! Sheesh! 2000 sq ft home and can’t get a queen sleeper sofa into bedroom 2. Looked at Murphy beds, but they take up the wall and can only be used as beds when pulled down, and you can’t put sitting furniture in front of them. A sleeper sofa would be much nicer as you could sit on it when not used as a bed. We haven’t done anything, yet, because we haven’t figured it out. So if you find an option, please post!

I'm not down there in my house to look, but I'm still perplexed that you can't go through the doors diagonally and then vertical in the hall. Is the hall that narrow you can't get it back to vertical from a diagonal position?

I'm sure I've put much bigger things through much smaller spaces.

forget the sofa idea....get a trundle bed instead. takes up a lot less room in the guest room and it opens to a king size bed, so you can sleep more people

If the sofa is longer than 80 inches, tilting it diagonally doesn't reduce the height enough to get it through the 80 inch high door. The door is only 30 inches wide. If the sofa won't fit through the door vertically, it probably won't fit diagonally either.

I had the same problem trying to get a sleep sofa in the front bedroom of a Jasmine. We tried every angle and position possible with no luck. Thanks to a very handy friend, we got it in but it was very painful. We disassembled the entire couch. Even with only the frame, the sofa would not go in. We finally removed stapled fabric so that we could get some flexibility in the frame and then rebuilt the sofa. When that home was sold, the sleep sofa remained in the front bedroom! Look into "bed in a chest".

We used a futon, disassemble, then assemble in room.

We had the same problem. We wanted a sleeper sofa for the 2nd bedroom but only had 80in to work with. The slider door angle towards the bedrooms was the problem. We went to City furniture and purchased the Asheville queen sleeper sofa in 79. It’s made specifically for the villages homes.
Not many colors to choose from but it was delivered last week and my husband loves it since we made that room a den/guest bedroom.

The La-Z-Boy furniture company makes some pieces of furniture that can be delivered to you partially assembled, with full assembly completed at your site after delivery. May be worth looking into in your situation.

I guess that depends on the length of the sofa. But you could certainly angle it enough to shave a few inches of height.

If attempting anything first remove any legs and remove all doors. It’s more work to not remove the. Believe me.

Years ago a neighbor removed his window to get a sofa sleeper into a bedroom.

Maybe, but the problem is making the turn from the foyer.
