The System Ultra®

Design by Poul Cadovius, 1957

DK3, DENMARK

In 1957, the Danish designer and manufacturer Poul Cadovius launched the shelving system SYSTEM ULTRA® as a successor to the iconic and successful ROYAL SYSTEM® from 1948. The design of SYSTEM ULTRA® is based on the same wall-hung principle as its famous predecessor, but it has its very own visual identity.

SYSTEM ULTRA® is characterized by its elegant, ultra-thin shelves with a wave-shaped edge profile that gives the shelving a beautiful organic shape. The system consists of wall-mounted rails and shelves with hangers in brass, stainless steel or black powder coated steel. It also comprises a clothes rack and a cabinet. In 2019 dk3 relaunched the original design from 1957 in steel, and now the steel components are accompanied by rails, shelves, and a cabinet in wood. The variety of SYSTEM ULTRA® offers the possibility to customize the system in multiple individual combinations, where the materials complement each other and accentuate the simple and elegant design.

In 1957, Poul Cadovius exhibited at the XI Triennale in Milan, where he won a silver medal for SYSTEM ULTRA®. A highly treasured prize and an international recognition of an exceptional design idea.

Materials

Rails: solid wood in oak/oil or walnut/oil

Wood shelves and cabinet: moulded veneer in oak/oil or walnut/oil

Steel shelves and clothes rack: black or green powder coated steel

Hangers: brass, stainless steel or black powder coated steel (screws same material as hangers)

The wood used for the SYSTEM ULTRA® rails contains more natural elements such as more visible wood grain, mirror (oak), sapwood, and putty-filled knots than the wood used for the ROYAL SYSTEM® rails.

Since brass is softer than steel, shelves w/ brass hangers are expected to "warp" more than shelves w/ steel hangers.

The shelves may deflect slightly over time. To maintain a straight profile, we recommend a max load of 30 lbs per shelf. Fluctuations in temperature and light incidence may influence the integrity of the shelves.
