The sectional sleeper is a midrange investment piece, with the version I chose costing $3,799. If you don’t need the chaise sectional, there is a version with just the sofa sleeper, priced at $2,299. And while a white couch can be very high-risk, Castlery claims that the Performance fabric is spill-resistant. We also no longer have a guest room, so we were looking for a sleeper sofa in order to still be able to host. Not just any sleeper sofa, though, a seating unicorn: a stylish, comfortable, non-bulky sleeper sectional.
