designer's own words:this is a folding bed with built-in curtain for outdoor use. normally, a bed with a big umbrella is the standard combination on beach side, but they are big, heavy and hard to carry. a-bed combined what these 2 products do in one single product, which is even can be folded to save storage space and easy to be carried around. it is perfect for beach, garden, poolside and anywhere outdoor. a-bed has a simple structure which can be manufactured easily, and the main material is wood. most importantly, it replaced two products with one, and saved storage and transportation space. all that means it is very environmental.
