The foldable kids’ furniture one encounters in playschools are typically miniatures of the adult versions. Their hard surfaces, complex assembly and awkward bulk render them inappropriate, if not dangerous for children. A colourful range of ?at-pack EVA foam seating, called ‘ZIPP’, addresses this with remarkable ?air. A single foam sheet is smartly cut, folded and fastened with a zipper, whose seam gives it enough stiffness to take the weight of a small child. The material is also excellent for embossing, a way to introduce graphics on to the product. Zipp is a beautiful example of frugal, simple, intelligent design.
