This chair is the third (and final) in a series of old-school stick chairs built with a batch of local black cherry. This particular example is inspired by one of my favorite 18th-century Welsh stick chairs, which features thin back sticks that splay out to meet a thin comb.
The “Family Tree of Chairs” letterpress poster is now available in green ink. (It is also available in black at the same link – so make sure you select the color you want before adding it to your cart.) There are 200 numbered copies of these 16” x 20” posters, printed on a thick, textured 100-percent cotton paper.
The above phrase could easily be the punchline to a Norwegian joke about our neighbours in the east. Here in Norway it’s a cultural staple to tell jokes about the Swedes. Unfortunately, this also says a lot about our own inferiority complex in our relationship to them. And I’ll be the first to admit it: We’re not as cool as they are. While we all agree that they talk weird, eat horrendous food (like rotten herring) and that IKEA is just an evil plot against the world. But they’re actually annoyingly successful at almost everything.
The Swedes are both great innovators and traditionalists. They even successfully export a lot of their ideas to the rest of the world. Among others, they’ve given us Abba, Wille Sundquist, Volvo, Bluetooth and Spotify. And even dynamite! Oh, and they designed the classic Coca-Cola bottle! And us Norwegians? Well, we’re famous for killing whales, raiding and pillaging villages around the world, skiing and brown cheese. How about that!
Therefore it’s no surprise that they also did some groundbreaking scientific research on chair design. Surprisingly, I’d had never heard about this. Which is a bit weird, considering I’m a nerdy chairmaker myself and live just next door to them. Instead, it all came to me when I excavated a dusty Åkerblom Chair from a Norwegian barn earlier this summer. When I started reading about the chair, I learned it was an interesting part of chairmaking history that has been long forgotten and perhaps little known outside our Scandinavian borders.
The Chair Doctor
The story starts with Bengt Åkerblom (1901-1990), a Swedish doctor who became a pioneer in the field of electromyography. This is simply put a method of studying and evaluating the muscular strain induced by different body positions and movements. It is done by measuring the electrical nerve activity in skeletal muscles. Dr. Åkerblom had a special interest in sitting postures. Through his studies, he pretty much laid the foundation for the science of modern ergonomics. In 1949 he released his 187-page long thesis called “Standing and Sitting Posture with Special Reference to the Construction of Chairs.” It was also sold as a hardcover book.
Bengt Åkerblom’s goal was to scientifically prove that a chair could be designed to minimize muscular strain and discomfort. In other words: to become the most comfortablechair possible. The main findings of the study were:
The position and shape of the backrest, which is applied to the weakest part of the spine
The importance of the height of the chair seat from the floor
The slope (also called the tilt) of the seat
The seat must allow for the sitter to move around and change between positions
He came to his conclusions through both lab experiments and observational studies of people using chairs in daily routines and work life. He found that chairs formed to mimic the human body usually gave no or too-little support to the lumbar spine. In other cases, the supporting area of the chair back was too high up. Åkerblom also proved that the seat would have to tilt the sitter backwards in order for the back rest to function properly. He also found that a chair seat that was too high above the floor would induce pressure on the underside of the sitter’s thighs. This would impair blood flow to the legs and result in fatigue and discomfort. Lastly, a pommel-less seat with only a shallow saddling to it would let the sitter easily shift position, which increases the sitter’s comfort over time.
It Takes Two to Tango
In 1931, another Swede, Gunnar Eklöf from Stockholm, graduated as an interior architect. After working for a lamp factory and some furniture makers for a few years, he was offered a job as a furniture and interior designer at Karolinska University Hospital in 1936. This is where his life took a turn.
During his work at the hospital he developed an interest in ergonomics. Although I have not been able to find out how, he must have met Dr. Åkerblom during this time. Immediately after the war, Åkerblom was finishing his thesis at the Karolinska University Hospital and was probably keen to try out his theories in real life. However he was a scientist, not a chairmaker. One can only imagine it must have been love at first sight between Åkerblom and Eklöf.
And so Gunnar Eklöf designed a simple stick chair based on Åkerblom’s findings. As you can see from the protoype drawing below, all of the main principles have been incorporated: The low seat (15-3/4″ above the floor), the 6° seat slope and the star of the show – the bent back sticks providing lumbar support at 6-1/2″ above the seat. The seat is almost flat and has a very subtle saddling, allowing the sitter to easily shift her weight.
Bringing it to the Masses
Neither Åkerblom or Eklöf were chairmakers. They needed help to bring the chair into life and about 1950 they contacted the Nässjö Chair Factory to manufacture the conceptual chair. The Åkerblom Chair required exact engineering, including steam-bending. At this time, the Nässjö Chair Factory was already one of the largest chair factories in the Nordic countries. Nässjö had started producing stick chairs and rocking chairs in 1870, so by the time they were contacted by the two young designers, they already had 80 years of experience under their belt.
The Nässjö Chair Factory photographed in 1932A chairmaker at work at the chair factory, working beside a mountain of chair seats. The photo was taken about 1950-1960.
During the years 1949 to 1958, more than 120,000 Åkerblom Chairs were produced and sold. All were made from solid Swedish birch and had the same conceptual features. Gunnar Eklöf designed several variants of the chair, including side chairs, dining chairs and arm chairs. The most popular model was the “SZ03,” a light and elegant armless stick chair that had all of Åkerblom’s ergonomics baked into the design.

The one I found in the barn however, was the Åkerblom Karmstolen – the armchair version of The Åkerblom Chair. It features a so-called “captured arm,” where the outer back sticks are mortised through the back part of the armrests. This is a common arm joint, but it is most common in old Irish stick chairs. The armchair is made from both solid and laminated birch. The seat is glued up from several pieces of solid wood. All of The Åkerblom Chairs had a maker’s mark under the seat to prove their authenticity.

So, How Does it Sit?
I’m pretty sure Dr. Åkerblom meant for his sitters to be upright and working at a desk. I’m not a desk guy, and I usually sit like a sack of potatoes. So I figured I’d put the chair to a test and sit like an office worker. And let me tell ya, it was dang comfortable. I almost felt like having a Swedish meatball and humming “Dancing Queen.” And for a Norwegian, that ain’t bad!
I don’t know how, but somehow we’re going to lose money on this poster. It’s just my fate.
So after selling out of our first run of “The Family Tree of Chairs” letterpress poster, we said we might do a second run in green ink if we had enough interest. Y’all spoke up, so we placed an order for 200 posters in green.
There was some miscommunication at the press, and they used black ink and shipped those 200 to us. I refuse to pulp these gorgeous posters because they are the wrong ink, so starting today we are selling them in our store. They are $33, individually numbered by Megan and are ready to be shipped from our warehouse in Indiana. You can place an order here.
The green ink poster, which will be for sale next week.
The printer insisted on doing the job correctly (thanks Boxcar!), and so next week will also have this poster in green ink. It will be the same price. And also numbered by Megan. So if you want a green one, just sit on your hands for a few days.
In other news, we asked our retailers if they wanted to carry the poster. Classic Hand Tools in the UK said yes! It will take some time to get them shipped across the Atlantic, so stay tuned if you are overseas.

A detail of the green ink. So as for you to see how green it is.
During my 25 years in the woodworking business, I’ve seen a lot of toolmakers both big and small disappear suddenly and unexpectedly. In the 1990s, I could not have guessed that Record Tools would self-implode and become a shadow brand of Rubbermaid.
I’m 53, and I hope to have at least another 25 years at the bench. A couple years ago, I started thinking about what I would do if I lost my Tite-Mark marking gauge and if Kevin Drake stopped making them for some reason.
So I immediately ordered a back-up Tite-Mark.
Since then, I’ve slowly acquired doubles of the tools that I would be lost without. It’s not a big list. I know I’ll always be able to get a Starrett 12” combination square or an old Stanley No. 5 at auction or at a tool swap. But if Lie-Nielsen disappeared because a flying saucer stole the factory, I think it would be tough to find replacements. Note that I don’t think of any of these toolmakers as particularly vulnerable to disappearing anytime soon. I just know that if they did disappear, getting a replacement would be difficult.
Here’s the list:
Tite-Mark Cutting Gauge. This tool is an extension of my hand, much like a marking knife. I am so attuned to it that I make micro adjustments almost unconsciously. Don’t accept imitations.
Lie-Nielsen 60-1/2 Block Plane. I’ve said this before, and I’ll say it again: The Lie-Nielsen 60-1/2 is the best block plane I’ve ever used. Full stop. No qualifiers. I’ve worn off all the paint on the top of the sidewalls. I wore out the blade it came with and am well into the second blade.
Lie-Nielsen No. 3 Bench Plane: The No. 3 fits my hand better than the ubiquitous No. 4. I have tuned up my bronze one to the point where I don’t even look at other smoothing planes on the internet or at tool stores.
Veritas Standard Reamer: It’s easy to make a tapered tenon cutter, so I’d hate to lose my standard reamer, which I use on most of my chairs. I have such a good feel for how it cuts that I rarely ever stray from my desired angle. In fact, I have to deliberately go off-angle when I teach others how to correct a hole that has gone astray.
Blue Spruce 16 oz. Mallet: The resin-infused mallet is another one of those tools that feels like I was born with it in my hand. I’m told the round mallet is for carvers, not joinery. Hogwash. This small tool packs an impressive punch and is incredibly durable. Blue Spruce is now owned by Woodpeckers, which is too bad because I like Dave Jeske so much, but it is still an excellent mallet.
Chris Vesper 4” Sliding Bevel: No surprises here. I have Vesper Fever. And the only known cure is to buy all of his tools. I have a full set of the sliding bevels and doubles of the 4” bevel.
You know what comes next: This is not a sponsored post. I bought these tools with my own money. And we don’t do affiliate programs or anything slimebally.
