Simplicity, minimal materials, and compact size. These are all components of good green design, and they're exemplified by this ladder design from Israeli designer Itay Laniado. Similar to Laniado's other designs, the ladder is held together by tension—no screws or glue involved—allowing it to be assembled and stored in a more efficient manner.
Laniado's ladder utilizes a tension system that relies on the ratchet to hold it together, which also doubles as a handle. The ladder is also collapsible and can be disassembled and assembled in a very compact way.
Laniado's Rope Table relies on a similar concept for stability. Red ropes are strung to the center, holding the legs inward and holding the table together. The legs sit in holes drilled in the top, requiring no fasteners.
