Wall bed
A bed that folds vertically into the wall (the Murphy bed), freeing the entire floor by day while keeping a real, full mattress for night. The gold standard for a daily living-to-bedroom layer — if the mechanism is good enough to use effortlessly every night.
Real bed, zero day-floor
Pair a counterbalanced wall bed with a slim cabinet alongside for bedding (humid storage ruins a folded mattress). It drops over a sofa zone in seconds — no compromise, unlike a cheap sofa-cum-bed.
