This piece from New York based artist and designer Sebastian Errazuriz reminds me of the Piano Hanger, I featured earlier this year. Here too, the simple and ingenious principle of a piano-like structure is applied to generate adjustable storage. The Piano Shelf folds flat when not in use, occupying zero space in the room. Once you need to store something – simply unfold the sufficient number of ‘keys’ to accommodate the item. Brilliant! The shelf comes in black and white.
