Israeli designer Itay Laniado has designed a collapsible ladder held together by a strap under tension.
The strap is tightened with a ratchet and forms two rungs of the ladder once assembled.
A loop in the strap acts as a handle once collapsed.
"The ladder is a tension system that relays on the ratchet to hold it, no screws or glue involved," says Laniado. "The ladder is also collapsible: it can be disassembled and assembled in a more compact way."
