The difference is therefore clear in itself, but when should you go for a sofa bed? If you like the fact that in addition to the bed function, there is also a possibility to sit down in that room, the sofa bed is a good choice. You get two functions in one. The furniture is suitable for both sitting and sleeping, so it is an ideal space winner. However, keep in mind that a sofa bed often has a depth of between 90 and 105 cm. average. This is therefore somewhat deeper than a normal sofa.
Another advantage is that a sofa bed is often a slightly 'cozier' option than a folding bed. There is a cozy upholstered sofa instead of a cabinet.
