Cadovius was born in Frederiksberg and originally trained as a saddler and upholsterer before turning to furniture design. He developed the original concept for the Royal System in 1948 as a means of freeing up valuable floor space from ever-increasing clutter.
As Cadovius observed, "Most of us live on the bottom of a cube. If we were to use the walls in the same way we use the floor, we would get more space to live in."
The Royal System was an immediate international success, due to its infinite flexibility and efficiency, and Cadovius founded the furniture company CADO in the late 1950s in order to meet demand. CADO subsequently took over the renowned Danish furniture manufacturing company France & Sons and at one point employed a workforce of 300 and exported products to over 30 countries. The original concept expanded to an extensive family of storage solutions and Cadovius took out over 400 patents to protect his work.
The Royal System was recognised with Gold Medal at Finland Furniture Fair in 1950 and silver at the Milan Triennale, establishing a benchmark for wall storage design.
