A hammock, has very long life, and you can sleep in it. The catch? Must have blocks on the sides. H = hammock| W = Wall, or tree, etc.| ‘-‘ = rope (visual, don’t have to craft it)|
All together, you’d have four “tiles” taken up by the combination, 2 being the hammock, 2 being a wall on either side.
Can hold up to 10 ‘drinks’ of water, distilled or not, and the whole thing can be distilled together, but that takes a long time. You can fill up a smaller, inventory-held container with the water in the tank like you would from the ground, until it runs out.
