If you just look, then this thing is like an ordinary chaise lounge, considering the design as a bed in the generally accepted sense is certainly difficult. It is believed that it should be completely different, and a swing or a hammock must be suspended. It’s more like a deck chair, although they have a slightly different design, you can not just lie on this, but also swing. And if the fabric is strong enough, then together.
The photo shows a factory copy, but you can also make it yourself. You will need a frame made of metal pipes to withstand a large load, it is not difficult to fit it with a cloth.
It looks not bad at all, somewhere near an artificial reservoir, in the garden you can relax very nicely.
