I used to have this overly large 3-piece sectional that I bought extremely discounted during the last day of a garage sale.

While it was too large for, well, all of my apartments, to have the couch laid out properly with all 3 sections (I often put the chaise lounge portion in another room) - I did discover that I could push all three pieces together into a rectangle that was the size of a queen sized bed, and had the couch back walls on 3 1/2 sides of the square. We’d line it with pillows and called it “The Nest” It was like a conversation pit / bed that could easily be topped with blanket ceilings for a cozy feeling, and many brunches, board game nights, sad cuddle piles, drunken hangouts, dates, and afternoon snoozes were had there.

Once we had the nest up for an entire year! People still ask after it.
Hm. I don’t love the current couch.
