The dominance of used plastic containers inspired inventive people to many different crafts. Of plastic bottles, in particular, they already don’t do anything, but it turns out that you can make furniture from them and build houses!
In the photo we see a bed constructed entirely from this container. Unless the mattress and pillow on it are made of bottles, they are ordinary, textile. Filling, it seems, is also not made of plastic. But the wall next to it is clearly a bottleneck, maybe the whole house is like this? When the water from the bottle next to it is drunk, it itself will probably also become a building material for the construction of other furniture.
