Sometime the best ideas are the one that seem so obvious once they are described. Like this one: If you fill your air mattress with helium you can keep it on the ceiling.
The same idea could be applied to any type of furniture that is inflatable, like a chair or a sofa.
William Calderwood’s patent in 1989 describes a bed that increases the floor space in a small apartment.
After you get up in the morning, the bed floats to the ceiling, and you can spend the making full use of the extra space. When bedtime arrives, you simply pull it down again by the tether.
You could probabaly get away without making your bed too, since nobody would ever see it. Brilliant – just don’t let it get too close to a flame!
