Here’s a clever solution for rooms with really small spaces using two twin mattresses. At night, the room has a comfortable bed to sleep on. But at daytime it’s a breezy open room with a lounge area to host parties and gatherings with friends, as well as provide an guest space:

I put legs on the mattresses with hooks to keep it all together during the night. We have the bedlinen in a basket next to the couch/bed. The top mattresses are the thin type, and I have made covers for them, so it is easy to make the bed in the evening.

The back cushions contains a foam mattress in the size 90 cm. by 90 cm. 9 cm. thick It is folded and hold together with a strap. When we have friend over two of these on the floor makes it out for one bed. The foam sort of makes the mattress stick to the floor so it doesn’t slide apart during the night. We make the bed in the extra room, so it is still possible to have a little privacy.
