Equilibrium shelves

Modular furniture brand Movisi has launched Make/Shift, an adjustable shelving system by Royal College of Art graduate Peter Marigold.
The system, made of Arpro expanded polypropylene, consists of wedge-shaped units with corrugated edges that tesselate to fill alcoves or spaces between columns.
Make/Shift also comes with clips that can be used to create freestanding assemblies.
