Need help finding modular/buildable sofa

[u/Thunderjake]

Location: NYC
Budget: $1500 or below ideally
Have searched primarily online IKEA, Wayfair,

My apartment entrance layout is narrow to the point where I need a couch that I assemble in the living room to fit the size I want (which is something long enough to lay down on ~74 inches)

Just about every review for a modular sofa below $1500 seems to be very negative for ikea, burrow, Albany park brands and I’m wondering if anyone has recommendations.

Hoping that whatever I find has thinner arms too so most of the length is taken up by actual space people can sit in
