Adjustable shelves usually feature holes and pins, but with London-based industrial designer Alexandra Gerber’s Up shelving system, “the shelves simply drop into a groove and lock in place with a quick release-lock,” she writes. The shelves can then “be moved up and down at any time by releasing the lock, and without affecting the other shelves, and retain a smooth and parallel movement.”
Both the shelves and sides are made from the same aluminum extrusions, while “the joints borrow technologies usually applied to window construction,” according to this short Q&A with Gerber.
I’m curious to see how the wider shelves hold up; is the extrusion sturdy enough to not sag under heavy books?
