I sat on what I'd consider the gold standard of sleeper sofa brands, and I didn't find it all that comfortable for sitting. Sure, the "bed" (essentially the mattress) was way better than any pullout I had ever slept on. But the sofa itself was kinda bulky, and the seat cushions felt stiff and dense, probably because they're made to downplay the sofa's mattress-folding mechanism (and often aren't constructed the way non-sleeper sofa cushions are with layers of foam and springs).
Getting living room mood lighting right can feel like a balancing act. Go too bright and the space feels stark, but leave it too dim and it quickly tips into gloomy rather than cosy. The trick is to find a lighting design that adapts to how you actually use the room. Mood lighting is all about layers. From overhead pendants to table lamps and wall lights, each source has a role to play.
