Where does everyone get a laser cutter for the house? AM I missing something? Did WalMart start carrying them?

Indeed not a thing to buy as in individual.
The good news is: there are "fablab"s around the world: places where people share expensive machines such as lasercutters and 3Dprinters. In a not commercial way, making it as affordable as possible :-).
Here you can find out if there is one near you: http://www.fabfoundation.org/fab-labs/

LOL, I appreciate the response. I was sort of being smartcastic due to all the ibles where they start with, Using your Binford Model 6745 laser cutter, and I am always like, who has these at home?

As a patent holder (8,453,366)and sort of inventor, I wish I could afford an industrial laser. I have a hard enough time heating kydex for shaping.

Thank you and I will be looking seriously at a local maker place.

Really nice. Great photos. The design is questionable, IMHO.

The implementation is so great. I love the hinge and all the pieces. The point-of-use instructions are such a nice touch. It's really... appealing in so many ways.

However, I wonder why you've decided to use a LASER cutter. Who cares how you cut it? Shouldn't you be more worried about the weight, strength, and longevity of the chair? That un-finished plywood needs a coating or it'll delaminate and all this nice work will be for nothing. How much does this thing weigh? I wonder if any other dis-assemble-able stool would compete on weight. And can you sit on it? Why bother with a low back? Doesn't that add another difficulty to the design that is only slightly useful in the field? It's not tall enough to really lounge but it's big enough to add weight.

Anyway, despite the criticism, it's really nice work. Thanks for posting.

I care that its cut on a laser... in fact I specifically look for laser cut projects. Not much is nicer than loading a piece of plywood into a machine, feeding it some plans and 10-20 minutes later, out pops a chair, or some widget, etc...

Thats not to say longevity, weight and strength are not important too though - I agree, they are - and critically so.

I might have a go at making this in the near future - but, I'm not a small guy; so we'll have to see how it goes... did you see anything in the design that could be improved to build on the strength?

I might look at 5mm ply instead of 3mm, but then the kerf bends might be interesting to achieve.

If the goal is to use certain equipment, fine. That is all well and good. It is an expression of luxury. It is self limiting. I prefer to start from a need and use whatever means necessary---the opposite, really, of looking for LASER-cut projects.

Here's an example of a good seat that is lightweight, packs small, and holds you up:

It's just one of lots of examples of camping chairs.

Well put, and frankly, pretty fair - its an interesting perspective that I hadn't considered.

For me, the laser cutter (and 3D printer) is a way of being able to physically realise something that I can happily design using CAD software, but previously have had no ability to fabricate with my own hands.

What is interesting though is that previously making things to fill needs has been completely out of the realms of possibility for someone as unskilled with their hands as myself - and rather than feeding laziness; computer aided manufacturing has actually pushed me to go out and buy hand and power tools to invariably add finishing touches, or reshape a bit of wood, or hack out some kind of mechanism to unlock my garage door with a couple of selenoids etc... - I'm learning every day, and best of all its fun.

It's a nice feeling knowing that you're not doomed to failure before you begin. For the first time since school woodshop class (I'm now 31) - I'm working with real materials building real things (i.e. not just bits of software as I do for a living).

In all sincerity - thank you; your message is enough 'food for thought' enough for me to strive not to make CNC my only path.

As a design, i like it very much. very interesting video and thank you so much for sharing the drawings too! :)
I could not imagine where it might fail unless i end up making one, but there should be other choices i hope. Can any one suggest alternative DIY chairs that are more light and portable other than magazine folds?!

That looks adorable and portable. Great documentation, and thanks for the weight limits in the comments.

very cool! but if its made of 3mm what weight will it hold?

author
Ryo+Kosaka made it!(author)2014-10-02

He weighs about 140 pounds. I think 180 pounds would be limit.

This chair might be for children and women.

I have too much emphasis on portability. So there are many problems in this chair still.
