Here is another bed design that I discarded a few months ago, because several others beat me to the punch. I’m posting it now because I felt there needed to be a design that was more functional and aimed at grown-ups.
The side engines are drawers, the top engine is a foldaway lamp. The sides of the mattress could be enclosed into the Landspeeder, but my preference is for an unobstructed mattress.
The bed would float from a small box frame underneath, or clear acrylic feet shown here. LED running lights could be placed underneath, which is all the rage with floating beds nowadays.
