Flexible furniture will always be fashionable and popular because it gives you an opportunity to change it according to your needs. Helical Shelf System by Ed Rawle is right one of these due to the triangular helixes, cogs, belts and shelves of which it consists. The shelves move up and down, and as they twist in opposite directions, they are rotated one shelf ascends and the other descends. The feet at the bottom are functional and sculptural, bracing the rods and housing each cog and belt. This is a curious kinematic 3D piece of furniture, cool for any modern interior.
