We learn about the two very collectible types:
‘Royal System’ and ‘System Cado’

vintage cado wall unitContinuing my research into midcentury modern shelving systems, Cado “floating” wall systems are now also in my sites. Like the String System that recently profiled, Cados are Scandinavian-designed — and they are hot collectibles. Unlike Strings, you cannot get them new today, so you must be on the lookout. You know how I say that at estate sales, you need to look to the windows for potentially lovely window treatments? Well now, I add to that list: Look to the walls for potentially valuable shelving systems. Above: Christa’s Cado Wall System.

Hi Pam –

I don’t have the String system, but the similar, all wood version of the Cado system…interesting that such similar ideas all were designed at around the same time .

cado wall unitI ended up getting mine from CraigsList, but it did take months and months to find it.

The reason…well my wonderful mid century split level has some floors that are, well, wobbly if you walk to hard…especially the dining room. My vintage blonde china cabinet was great, except that every time somebody walked by it, it would sway and things would clank and clunk inside (it made me afraid for my grandmother’s china!)

So a teak Cado system, that attached to the wall ( they have floor standing ones as well) Solved the problem. Too bad the wobbly floor itself is not so easy to fix!

This type of system is so flexible (actually have Elfa in my daughters room and our study) and can work just about anywhere you want to put it!

cado shelf unitsI took these a while ago, I have done some “tweaking” since I took these,  especially with the Viking glass, ( LOVE Viking Epic…I have gotten slightly addicted) I got some more pieces, I move things around…it is a constant thing.

I have another wall-mount and one other cabinet for the Cado, but as you can see, two bays were all I had space for or need , but I have them safely tucked away in case I change my mind and want to put this somewhere else.cado shelf unitThe “down side” to this (the Cado)…actually getting it on the wall…if your measurements are not PERFECT, the dowels on the back of the cabinets will not go in the holes.  I learned that my studs are not straight in the walls…as if I got the upright in a stud at the top, it would not go in a stud at the bottom.  It took about 4 hours, 3 people,( myself, DH, and a very patient and tall friend ) several bruises each and much cursing to get it up.  I would assume that when the system was new there was some sort of template, so you could easily get things lined up, but those are long gone I fear.

Thank you, Christa, for sharing these photos and advice. Your home is drop dead gorgeous!! Readers, check out Christa’s etsy shop, The Red Retro Shop, here.

About the Cado wall system

I went searching all over the internet trying to piece together a timeline history of the Cado system. The timeline is incomplete, I note* where I am missing info or am confused.

  • According to the 20th Century forum, the official name of this design is the Royal System. Although then I read there was also a design called System Cado. Confused*. In any case, these were designed by the Dutch architect Poul Cadovius, and manufactured by Cado, Cadovius’ eponymous company.
  • I found a Wikipedia entry for Poul Cadovius. It appears to be in Danish, and the translate pop up is not popping. However, I think I can read that Cadovius died just last year, 2011. He lived to age 99! I also am going to guess that the Cado wall unit was spotlighted (introduced???) at the Milan Trienniele in 1957? Can anyone translate for me?
  • I scanned the Wiki on Danish Modern Design — and he does not seem to be mentioned. It is interesting — the Cado wall units seem to be very popular — very well known — but there is very little information I can find overall on Poul Cadovius, Cado manufacturing, and the history of these units.
  • At Made-Good — a site about Danish design — they describe the impetus of the Royal System:  “Poul Cadovius, was in the fifties looking for a furnishing system which would give a maximum of comfort, underline the personal atmosphere of the interior, was easy to assembly, offer a lot of combination possibilities and made the living space larger.” They add that, “In the late 60s [1964, another post indicates] he (Cadovius) (als0) bought the famous manufacturer France and Sons and produced many more furniture under the label of Cado.”  Cadovius/Cado went on to produce a variety of other furniture designs.
  • This Design Addict forum says the first Cado was a freestanding system — they have a photo — and that it was designed in 1955. Design Addict also has a classifieds section that indicates that the Cado system was available in a number of woodgrains — teak, walnut, mahogany, rosewood… — as well as white. You can also see the variety of components.
  • The Good Mod adds that, “These systems could be ordered from catalogs and furniture stores in the 1960?s – 70?s. There were many different types of cabinets, shelves, lights, standards or uprights and styles. Whether you needed a desk, a table, a stereo cabinet, china cabinets or a chest of drawers, you could customize the system to fit your needs.”
From Roche-Bobois
  • Looks like Roche Bobois started distributing the Cado system in 1962. [I’m confused about when Cado manufacturing came into the picture.] Note, they say it marks the end of conformity in shelving sizes, “The break in conventional sizes has just begun.”
  • On this forum I read that there are two designs of the Cado system — one with metal fixings, one with wood. Here is an edited excerpt: [One design] has the metal fixings and supports which hang in the sides of the wall battens. Here is a clear example. [The other design] has wooden supports with angled wooden dowels in the back which fix into angled holes in the front of the wall battens. (Christa has this all-wood system; here is another clear example. The joinery involved means these systems are often considered more desireable. This also means it’s a nightmare to put up as there is zero tolerance. The [system with metal fixings] is much more forgiving and is easier to find. *Still confusion over which was called Royal System vs. System Cado. Confused*.
  • I cannot find any information on when sales of the Royal System ended.
  • Interesting article — more info about Poul Cadovius’ career here. A photo too. Scroll to “The Story Behind Circulhuset” about half way through the PDF. In short, she says Cadovius was a well-known and prolific designer, with 400 patents. She also says that Cadovius had gone bankrupt by 1981.
  • abstracta tableBut golly gee, looky here, the Cadovius’ Abstracta modular shelving, designed in the 1960s, still is for sale — looks like it’s manufactured in K-zoo! That’s Kalamazoo, Michigan, where Elvis still lives, btw. The Abstracta appears to be mostly targeted at the retail display market, but there are a few pieces designed for home: The cube table! Of course, we all recognize the cube table!

And… how’s this for some loveliness — a video that shows the original turntable and speakers:

Cado wall systems buying guide:

My tips:

  • Cado systems seem to be well known among dealers and collectors. They are very recognizable to the infomed — which now includes you. However, that means, that if a dealer or collector gets one in-hand, he or she will price it accordingly — likely starting at $1,000 or more, depending on the pieces available and the condition.
  • If you are looking for a bargain, I’d say try estate sales and vintage stores, especially those in smaller cities or towns where they be fewer buyers tuned into the mid mod. Look to the walls! Keep your eyes peeled! I tend to think that Cados were pretty popular back in the day — they are out there to be discovered.
  • You can also watch craigslist. Search Cado, teak, danish modern, midcentury, shelves, wall unit… etc. Mix up your terms. For example, I spotted this unit for sale in the New York City area, and the seller gave me permission to feature the photo here:

Cado wall system with desk, $1250 (link now gone):  Beautiful and practical Danish modern teak wall system designed by Poul Cadovius. This system as shown in the photos is particularly rare as it comes with a separate drop-leaf desk. The condition overall is in good condition with a few scapes and bumps that comes with age. [Thanks to the seller for giving me permission to feature this photo.}

  • You can also find Cado wall units on ebay and etsy — but you will likely not be able to see what you are buying in person, of course.

So there you have it: Cado wall systems. Paol Cadovius, well done!

Readers — I welcome your additional info and insights about Cados.

  1. Sue Cartier says:

    I have a wall unit with a denmark sticker on the underside of one of the shelves. How do I find more info. Almost looks like some pinhole marks beside the label

  2. Cheryl says:

    Did Poul Cadovius design furniture other than the infamous wall units? I have a freestanding desk that I suspect may have been designed by Cadovius, but I am having a really hard time trying to figure that out. The pulls on the desk are little brass half circles, exactly like ones I have seen on the shelving systems. The styling of the desk also seems consistent w the styling of the shelving systems.

  3. John Crabtree says:

    I just wanted to say how much I enjoyed reading your extremely informative article on these Cadovius wall units. I like learning of all sorts but a little bit of humor thrown in does make the information even more interesting and makes me chuckle instead of snore.
    So, thank you…

  4. Kate says:


    I have two teak (i think) cabinets of what I think is a Pool Cadovius wall unit system. The badge on the back says Danish Royal System 1960 and there is a logo that looks like a cross between a heart and a triangle with the letter B on one side and S on the other. Each of the cabinets has two small brass brackets on the back at each side. Does anyone know how these cabinets hung form the uprights? I don’t have the uprights but had a metal frame made but I’m uncertain if it will work. I want to reproduce the original fixings in either metal or wood but can’t work out how the cabinets fit to the uprights. The frame I have made has a bar between each upright but I’d like to know how the original design was put together. I’d also like to be able to change the position of the cabinets which I wouldn’t manage with my frame. I’d welcome the thoughts of anyone in the know.

  5. Meredith says:

    Can anyone help me find a replacement Mortise lock mechanism for my newly inherited Poul Cadovius Royal System? I contacted DK3 but they state all their parts do not fit systems prior to 1985. Mine is from the mid-60s.
    My cabinet lock with skeleton key has a broken spring and getting it rebuilt is a hefty price according to a locksmith I went to. I’m looking on ebay to no avail.

  6. Lynne says:

    I* have what I believe is a Cado wall system. I received it from my parents when they sold their home. It has the wooden supports under the shelves. My issue is the lock on the desk unit will not turn. Any suggestions on how to repair this or people who repair these units? I live in Massachuetts.

  7. Brian B. Egan says:

    Since I am currently visiting Copenhagen, I thought I would Google the wall unit I bought in 1972, and found your site. Mine is the floor-standing modular oiled teak system, which is called the Cado «Cresca». It’s apparently now very rare. I am trying to find an aluminum drawer handle for it.

  8. Danish http://www.dk3.dk today produces the ROYAL SYSTEM, designed by Poul Cadovius in 1948. It was relaunched in 2010 after 25 years of “sleeping”. SYSTEM CADO will be launched in 2017. Unfortunately, there is not much information around on Poul Cadovius, mainly because he was not one of the “academics” like Wegner, Finn Juhl, Jacobsen etc. But dk3 is working on it. Contact dk3 on info@dk3.dk if you want to know more.

  9. Deana says:

    A shot in the dark…I’ve inherited a Cado-like system. Teak, stamped “Made in Sweden” on the back. Instead of the metal brackets or wooden supports, however, all the pieces on this have holes where *something attaches the shelves to the wall strips. The hardware, however, is missing, and I cannot figure out what is supposed to go there. I can’t find a manufacturer name on anything…Happy to provide photos if anyone is still check in here.
