I can also highly recommend Enzio Mari's Autoprogettazione furniture. Although slightly more involved in construction, all you need is standard planks, hand saw, a hammer and some nails. The instruction PDF can be found online (chairs in the latter half):

https://syllabus.pirate.care/library/Enzo%20Mari/Autoprogett...

bArray

Just looking through that PDF, unlike the chair in the blog, some of that furniture is not as robust. Pages 46 & 47 the load rests on the corner of the wood, and pages 46, 47 & 52 add almost all load onto the screws.

The chair in the blog benefits from essentially having all load bearing done by the wood, any screws or nails would be superficial only. We have several good hard wood chairs here with dove tail joints and spring based cushions - and they are excellent.

sandworm101

The chair in the blog is not robust. It is simple, but not robust. It contains a hinge with an extreem amount of force placed on a small area of wood. It will deform very quickly, changing the angle of the recline. Similarly, the sharp points in contact with the ground will wear/weather quickly, putting it out of level. Rustic and utilitarian, but not meant to last. Imho.

>It will deform very quickly, changing the angle of the recline.

Nah, I've seen a bunch of these over the years, they basically last forever.

I think you should check your own knowledge before double-guessing Enzo Mari - a designer who did the work and had extensive knowledge of form and materials spanning decades.

This is not an ""argument from authority" but "Chesterton's Fence".

bArray

Maybe Enzo's implementation was fantastic, but the problem with not specifying these things is that it's not clear if one or one hundred nails should be used to secure each part.

One thing to observe is that people were lighter traditionally (i.e. prior to 1974 when this was published), and the load bearing capacity of a chair was less important than it is today. Also bare in mind that wood has become far more expensive, and people of today would likely be using less dense wood.

On page 52 for example, each leg (E) is nailed/screwed into C by just three points. The C wood itself is in a strong configuration, but the legs are almost an afterthought. Without any lower support (e.g. as shown on page 56), the nails/screws will eventually be levered out. The actual loading on the leg itself is not great, with three nails/screws seemingly aligned with the grain. The result would be a split that runs along the grain, and that may have been what happened to the left leg in the picture.

tshaddox

Both of those types of arguments are false.

This reminds me of the Segal Method of housebuilding: https://www.designingbuildings.co.uk/wiki/Segal_Method

Two of the core ideas are that the majority of the work can be undertaken by a single person with basic carpentry skills, using readily-available materials in standard sizes so there is minimal cutting and waste.

turtlebits

Having built a couple of smaller structures, I don't see why these can't be done today. Ignoring the current trend of building for curb appeal instead of practicality, you can build a house using standard size materials (8/10/12/16 foot). Even studs come in 92 5/8" to accomodate for top/bottom plates in 8 foot walls.

regularfry

I'm always intrigued by the Segal method, but it's so closely tied to the sizes of construction materials available at the time and I can't help wondering if anything has changed since.

frereubu

I'm sure it requires a bit of rethinking here or there, but there's a group of houses in Brighton, UK, that did it in the late 90s, a long time after Segal's original ideas: https://www.granddesignsmagazine.com/grand-designs-houses/he...

I've been thinking about doing this, and my main thought is that the insulation standards were probably effectively non-existent at the time, beyond "as few draughts as possible"!

Edit: not sure if these will be geo-blocked, but there are a couple of programmes about that project here:

Very nice! thanks for that. I really like basic agricultural do it yourself furniture. We should reclaim our furniture and be less dependent on IKEA et al. I'm defo going to try the adjustable table at the top of the pdf, thats a work of art.

Cthulhu_

Ironically, companies like Ikea have started selling products aimed at people making their own furniture; the "outdoor bench made from pallets" is pretty popular, and ikea & co sell cushions just for those.

I never understood those tbh, used pallets are splintery. I wouldn't be surprised if you can buy pallets specifically made for use in upcycle projects.

fake edit after a quick search: yup, you can buy readymade pallet benches or benches "inspired by" pallet projects.

Like Amazon continuing the DIY door desk long after it became more expensive than just buying desks. For some reason, people will pay a premium for the refurbished industrial look.

analog31

From what I've read, pallets are treated with all kinds of nasty chemicals.

thanks, i hate it ("it" being the recuperation of DIY)

soperj

It's like brutalism furniture design. woof.

aredox

Can it be brutalist when you have the richness of wood in full diplay, veins, shimmer and knots all apparent?

And nothing stops you to paint them or engrave them.

Is a wooden box "brutalist" too? It is a box. It is square. Is the the same as a square windowless concrete building?

WillEngler

> Can it be brutalist when you have the richness of wood in full display, veins, shimmer and knots all apparent?

Insofar as brutalism is about showcasing the raw building materials, yes, I think this is precisely what brutalism is about. Brutalism often uses concrete, but the big idea is to showcase the underlying material. (And if wood is more beautiful than concrete, great!)

Suppafly

IME, most people that complain about brutalism don't know what it is anyway and even if they roughly do, are only familiar with decades old ran down versions and not the original vision.

aredox

What is interesting also in Enzo Mari's concept is that there is no instructions, you have to figure out the best order of operations and how to offset some planks with others.

For those of you who start from really zero and have no idea how to start, here is a step-by-step for a couple of pieces: https://lieu-subjectif.com/documents/caue-22-rietveld-mari.p...

If really you want a "cheat sheet", there's whole book to help: https://filmandfurniture.com/product/hammer-nail-making-and-...

But try not to use it too much, because it really defeats the purpose of Mari, which it is to get people to "think with their hands".

Digging through the legacy and follow-ups of Autoprogettazione is also interesting:

I had never seen this type of chair before moving to Senegal as an expat. For several months, I didn’t try them because I assumed they must be incredibly uncomfortable. To be honest, most are made from thinner wood (people here are really poor!), so they didn’t look very sturdy either.

But a few weeks ago, I visited a local woodworker and ordered one of these chairs. I had to let go of all my previous prejudices - this type of chair is surprisingly comfortable and stable. And it's even useful for certain "other" activities :-D

Suppafly

Even though they are African in origin (perhaps as birthing chairs), a lot of people know these as 'viking chairs' or sometimes as 'bog chairs' and you see them at SCA events and various sorts of old timey reenactment type gatherings, often decorated with celtic knots and such motifs.

Crazy to see them warrant a posting here, I had assumed most people had seen them before.

world2vec

OK, I'll bite: what "other" activities? Am I being too dense? :O

tasuki

I'd hazard a guess the other activities involve more than one person...

y-curious

Imo, it looks a bit uncomfortable for chess, but whatever floats your boat dude

nomel

If you tilt it up 90 degrees, you can use it like a see-saw.

quickthrowman

Yes, you’re being too dense ;)

They’re talking about the chair being useful during sex.

bloppe

That chair is way too large to use for sex

peter422

This chair is made from pressure treated wood. Technically speaking, it is safe to sit on, but personally I'd like to avoid those chemicals against my skin if I could. Regular lumber probably would be preferable, especially when it would take $10 and 20 minutes to replace it after 5 years when it has rotted (or you could spring for redwood or cedar for an extra $10 and double or triple the life of your chair).

jdhendrickson

Most pressure treated lumber eschews the old arsenic method. Most only have copper and an anti fungal (Tebuconazole) in it. Perfectly safe for an outdoor chair.

Bluestrike2

The problem with using modern pressure treated wood for outdoor furniture is less any cancer risks like with the old CCA treatments, and more that it's just a bad choice for a bunch of different reasons.

Modern copper-based treatments--e.g. ACQ or CA--still cause skin and eye irritation. If you try to sand it so that people sitting in your new chair don't get a nasty splinter somewhere best avoided, you can compromise the effectiveness of the treatment (even when the treatment gets full penetration, it's still most effective on the outer layers you're now sanding away). Plus, while the dust you create when working with it might not include arsenic, it's still nasty to breathe in and can cause respiratory problems. Staining P/T wood can be a whole ordeal in itself, and because interact much more closely with furniture than say a deck, any imperfections will be more noticeable.

Even then, it's not like P/T furniture isn't going to require ongoing maintenance in the future. At which point, you're better off with something like cedar or white oak. Hell, with a decent outdoor grade finish and proper care, even untreated pine is going to last for years without rotting away underneath you.

euroderf

Basic weatherproofing treatments for basic lumber ? There's tar, which nobody does at home. There's wood oil. What else is there ? Do I have other options ?

bbarnett

You can buy normal wood, then apply treatments afterwards, then stain or what not.

Still trouble when the chair is at end of life, and you burn or bury it.

bArray

We used to treat wood with oil (literally from kitchen oil to motor oil). Apparently the Japanese burn theirs to treat it [1]. I don't think you have to leave it to rot out.

[1] https://www.instructables.com/How-to-Burn-Stain-Wood-Aka-Sho...

0xbadcafebee

Keep in mind Yakisugi ("shou sugi ban" is a Western misinterpretation circa ~1995) is traditionally performed on wood which is already weather resistant, particularly Japanese Cedar ("sugi" is cryptomeria japonica, a type of cypress endemic to Japan). Even then they still treat it with oil regularly to improve its longevity. So I wouldn't char some white pine and stick it outside and expect it to last.

harrall

We still treat wood with oil. Your local home improvement store should stock a bunch and you’ll find more at a woodworking store.

You can also add a sealant on top like polyutherane if you want it to last even longer at the cost of imparting a different texture.

asdefghyk

RE ...pressure treated wood.... In my country such timber is banned in certain situations - for example children's playgrounds ...

mbrock

I'd rather have my kids play on pressure treated timber than rotting timber...

adrianN

Fortunately those are not the only two options.

Cthulhu_

That's a false dichotomy and I'm sure you can do better.

sgt

As a parent you just spend a minute or two inspecting a playground. It's easy to spot something that is rotting.

keyle

I'm not familiar with this. What are the dangers?

steamrolled

Back in the olden days, pressure-treated wood contained compounds of arsenic and chromium. This made it pretty terrible to cut, sand, burn, etc.

The warnings persist in part because older wood still has that problem, so "reclaimed wood" projects can be risky. That said, since mid-2000s, wood in the US and the EU is treated primarily with much safer copper compounds. Copper isn't hugely toxic to humans at the levels you're likely to be exposed to from wood.

To be fair, the treatment often also includes an organic fungicide (the "azole" part in "copper azole"), which is probably not understood as well as copper.

Cthulhu_

That puts me in mind of old railway sleepers being used for garden projects like raised beds and low walls. They were treated with ??? something, in summer the black tar would leech out of them.

motorest

> I'm not familiar with this. What are the dangers?

Wood is typically treated with nasty chemicals. For example, formaldehyde is extensively used in these applications, and it's linked with cancer.

https://www.cancer.org/cancer/risk-prevention/chemicals/form...

alwa

Is formaldehyde used in treating PT lumber? That link suggests it shows up in resins for engineered wood products, like particleboard for interior furniture.

I was of the impression that PT lumber to modern standards involved relatively innocuous copper plus an organic biocide like an azole (for antifungal purposes), no?

And I thought the formaldehyde-heavy resins were regulated into obscurity back in like 2009, were they not?

0_____0

A simple urethane or even latex paint would suffice to protect untreated wood from the elements

hcarvalhoalves

This is the first chair one can make, it's a common pre-industrial chair design. Search for "tribal chair" or "2-piece chair" for examples.

It gets even better with wood carving (rather than building out of straight planks):

https://www.1stdibs.com/furniture/seating/chairs/african-sol...

aziaziazi

How do you carve solid wood board ?

I've done ten's of carving by gluing thin layers in a mold to create carved plywood. Those are extra strong but required to use quite a lot of glue and get the right thickness wood veneers. Would love to learn the solid board way.

edit: fined tuned my English today: seems carving means sculpting and not bending.

hcarvalhoalves

The traditional methods of "carving" I know about are using an adze [1] and controlled burning [2].

bradly

In my chairs I just sculpt the back out of eight quarter with an angle grinder. More production focused wood workers are using multi-axis routers/cncs.

The english term for what you are referring to in bent lamination which is done by taking a piece of wood, slicing it to sections with a thin kerf blade, soaking in water, and then clamping to a form and gluing back together. This is how Russ Filbeck creates his classic presidential rocker.

phito

I've seen people doing it with steam

shaftway

And you can bend surprisingly thick wood with steam. I attended a demonstration where someone bent a maple 2 by 4 (1.5" x 3.5"). It took about 6 people and two tries (the first one splintered, probably not steamed enough).

cgio

And gets pricier too. The prices are absolutely eye watering!

Here is an ultralight carbon fiber backpacking version:

https://youtu.be/-GEwwMbqU2o

beAbU

The ultralight community never ceases to amaze me.

I always thought it was all about travel as light as possible

But I think it's more about travel with as many things as possible - the lightness of the objects is just an emergent requirement in order to not break your back.

I've done my fair share of hiking, longest being a 90km 5-day hike in the Namibian desert, with no facilities save for a river. Weight was a big factor, because you needed to pack food for at least 8 days to be safe and there is nowhere to get food once you start the hike. What equipment you pack and the weight of said equipment weight had to be kept at a minimum.

Having said that...

A chair or other seating arrangement was by a large margin the lowest priority item on my list. There is one giant chair under our feet the whole time: the ground. And if that is not suitable, finding a stump or a rock or whatever to sit on is really not that hard and it's infinitely more environmentally friendly.

bradly

> The ultralight community never ceases to amaze me.

The ultralight community doesn't typically touch this stuff. This is sold to traditional backpackers that are drawn to the allure of ultralight.

cinntaile

No sane hiker brings a chair along on a 4+ hiking trip.

CrimsonCape

Glass half empty: No sane hiker brings a chair along on a 4+ hiking trip.

Glass half full: If I cut 14 oz of weight out of this pack by removing zipper pulls, straps, cords, carrying cases, and switch everything to 10x cost titanium, the chair is practically free.

user_of_the_wek

I find it weird that low weight is one of the main selling points of this product, but they don't say how much it is.

unwind

Yes, weird. I also liked this part:

Embers from a fire won’t burn the surface (If removed quickly).

I think that is true for many surface materials, and that "quickly" is doing a lot of work in that sentence. It also completely fails to communicate whether or not a carbon fiber chair is "safe enough" around an open fire. Annoying.

After digging around, the FAQ says "approximately 2 lb"

Clear example of why people like TikTok. There's no reason that video should be 10 minutes.

jader201

I just watched the whole thing, and I didn’t mind.

I feel like people have just gotten so used to 10-second videos, and anything longer now feels like an eternity.

I really hope people don’t stop making longer form videos in favor of TikTok-sized videos.

neilv

But, clicking around randomly, it seems that this video has been dragged out in length for no reason other than to be longer, presumably for YouTube financial (perverse) incentives.

gherkinnn

I don't watch any reels/shorts/etc and find this style of bloated YT video unbearable. I am all for long form videos, but have the decency to go beyond an empty vessel for ads.

GuB-42

I agree, but would be even worse as a TikTok video.

Shorts are absolutely terrible as product reviews. The point of a product review is to explore different aspects and use cases, otherwise it is an ad. It doesn't mean that long videos can't be ads, but short videos can't be anything but ads (if positive).

Shorts have a place, TikTok is great for silly dance moves, magic tricks, or people working really fast. You can even have short form educative content, though it usually doesn't go further than random trivia. But product reviews just don't work, unless they are ads. And in fact, ads don't even work that well as people tend to forget about them quickly.

seszett

Not sure about TikTok, but in this video and YouTube in general, you can just directly go to where most people go, and this way (I'm always a bit amazed that this actually works) you can generally see the actually important points of the video.

MangoToupe

TikTok caps video length. Indeed, the #1 issue with youtube is the videos are way too long. (Also the ads, and comments, recommendations, search, etc,) but video length is certainly why I haven't bothered to watch anything on youtube for a long time (edit: logged in. I still watch clips people send me ofc in the group chat ofc). I'd delete my account if it weren't tied to my email for some inexplicable reason.

odysseus

How do you "directly go to where most people go"? Assuming you don't have timestamps in the comments or video description.

woleium

There is a “ten minute rule” for youtube video to maximize reach / clout / whatever the kids are looking for.

spencerflem

Its ad revenue, I think. Yt pays out more for that length since it has midroll ads.

quantadev

That carbon fiber seat is cool. Could be made to integrate right into the back of a backpack (like the rigid frame), to help the backpack stay rigid during use, so it's kind of dual purpose.

Anybody wanting to get started making regular chairs using traditional methods I highly recommend Make a Chair from a Tree by Jennie Alexander:

https://lostartpress.com/products/make-a-chair-from-a-tree

In the book she starts with the basics and works up to assembly including woven seats. These are beautiful lightweight chairs. Even if you don't build the chair, it's a great lesson in wooworking.

MaDeuce

Thanks for reminding me that I haven't been to the Lost Art Press site in a while. I have a few of their books; they are fantastic. If you are interested in quality woodworking tools and high-quality woodworking books (both in terms of content as well as binding and paper), check them out.

I hadn't seen their "Build a Chair from Bullshit" book before. I've always been a little intimidated at the thought of building a chair, but this one looks like it's easy to build and has nice lines. Definitely more involved than the OP's chair, but it still looks still approachable with basic tools and skills.

https://blog.lostartpress.com/wp-content/uploads/2025/05/BAC...

Edit: As mentioned in dlbucci's comment below, I forgot to mention that it's available for free as a downloadable PDF book as well as for purchase as high quality bound book on their site. If you have any interest in an easy to build chair with an attractive design, it's worth a look.

dlbucci

It's a new book (and free!). There's also a YouTube series where they build it, so I'm very tempted to make my first chair now.

regularfry

Another "next step" to follow on from this is the Anarchist's Design Book: https://lostartpress.com/products/the-anarchists-design-book

It starts out not much more complicated than this and builds to a surprising array of furniture projects with a very small number of techniques. Although the actual materials are a bit annoying: it leans heavily on cut nails and specifically not the more easy to buy wire nails you usually see in DIY shops.

But also, the book is a physically gorgeous artefact in its own right. The illustrations are delicious.

alistairSH

During peak COVID boredom, I made a pair of wine barrel chairs, using this design[1]. Old wine barrels can be found reasonably cheap and the pattern is easy - only a few cuts, a drill, and some screws.

When it comes to woodworking, I quite enjoyed watching some of the videos of Granpa Amu on youtube. When I seen him make table from one piece of wood, it felt like magic.

Link for those interested: https://www.youtube.com/@GrandpaAmu

ansgri

It's deceptively simple.

I have a lot of lumber from previous construction projects, and all the basic woodworking tools. I also have some relevant skills. Would I be able to build it right now? No, need a wide and sturdy board, widest I have is 150x30mm pinewood. Would I make one if I had a proper piece of wood? Also no, I just don't want to accept the structural weakness here. And this joint actually requires some precision, which is not trivial (at least for me) with handheld circular saw!

Haven't built a chair yet, but my go-to design would be something like Adirondack.

0xbadcafebee

Nice! However some humans can be quite heavy. Depending on the wood species, the board may break, especially if they drop down into it. To strengthen it you can glue+screw a board on-edge to the middle of the bottom of both boards (running front-to-back, not side-to-side). This will significantly increase its bending strength but hardly be noticeable.
