Danish Modular Teak Extensive Shelf System by Poul Cadovius for Cado Royal, 1950s

Danish designer and manufacturer Poul Cadovius was born in Frederiksberg in 1911. Originally trained as a saddler and upholster, Cadovius became interested in industrial design and established his own furniture manufacturing company under the name of Royal Systems in 1945. Shortly after, Cadovius had the revolutionary idea to design a floating, modular shelving system that would maximize floor space and signify the end of conformity in shelving. The Royal System (1948) shelving unit  went on to win the gold medal at the Finland Furniture Fair in 1950 and silver medal at the XI Triennale di Milano 1957 and remained a hallmark of midcentury modern design throughout the 1950s and ‘60s.

Sometime between 1964 and 1967, Cadovius purchased the well-established furniture manufacturer France & Søn—credited with the industrialization of teak furniture production—and eventually renamed the company CADO. Cadovius collaborated with the impressive roster of iconic Danish designers through France & Søn and CADO, including Sigvar Bernadotte, Grete Jalk, Arne Vodder, Edvard Kindt-Larsen, and Finn Juhl. Pieces manufactured by CADO include Ditte & Adrian Heath’s 594 Dining Table and Chairs (1971), Steen Ostergaard’s Lounge Chair and Model 290 Chairs (1968), Ole Wanscher’s Senator Chair series (1960s), as well as a series of coffee tables in the 1960s by Cadovius that feature the use of aluminum, rosewood, and hand-painted designs by Susan Fjedldoe Mygge.

His minimalistic aesthetic is considered a perfect harmony between form and function—industrial and organic, affordable and elegant. Although the Royal System shelving unit was his main contribution to Danish modernism, Cadovius registered more than 400 patents throughout his long career, leaving behind a legacy that inspired many future designers.

Cadovius passed away in 2011 at the age of 99. 

Given the popularity of vintage Cado shelving units and other pieces of furniture, it is surprising that so little information about the Danish manufacturer’s history survives.

Cado began as modernist furniture producer France & Søn, which was founded by British entrepreneur Charles W. France and Danish cabinetmaker Eric Daverkosen circa 1948 in Denmark (originally named France & Daverkosen after its founders). The company entered a new phase when successful Danish designer Poul Cadovius (1911-2011) took ownership sometime between 1964 and 1967. The iconic Senator Chair (1951) by Ole Wanscher—along with a number of designs by Grete Jalk, Finn Juhl, and Arne Vodder—continued to be produced by Cado into the late 1960s.

Cado is best remembered for the modular wooden wall units designed by Cadovius. Named Royal System, the space saving exemplar of Danish modernism dominates Cadovius's legacy, even as he patented approximately 400 designs in his lifetime. Unfortunately, there is no information as to what happened to the Cado business after the 1970s.
