The Cima Ladder is reinvention of a classic tool. By using a carbon fiber composite and eliminating other movable parts, the 7 foot Cima Ladder is able to weigh in at barely 2 pounds.
The designers of the Cima Ladder claim its staggered steps are more natural to use than the classic ladder. I can’t imagine they’d be that natural to just stand on if you were doing something like painting a house. But for climbing from Point A to Point B, it does seem quite functional.
