Some pictures of 12th C beds, for Amalie, who made almost exactly the tent I want, so I'm hoping she'll make the bed I want and then I can find someone to make a copy of her prototype :-). The other pictures of people sleeping show what may be simple pallets on the ground, people just wrapped in cloaks of blankets, pictures which smudge out the details of what they are lying on, and people lying on beds that look like slabs with no upright features. These depictions of beds are all fairly similar in construction, and look lightweight enough to use for camping, indeed one is shown in a tent below. Notice how these beds often double as couches.

I quite like this one - a couch and bed combined, the rails at the back, as well as acting as backrests, could be used to hang clothing over. Although they may limit how close the bed can be placed to sloping tents walls.

This bed is a different style - we can't see the legs properly, but the bed head is a solid piece, instead of two poles and a crossbar.
