Introduction: K'nex Chair

Picture of K'nex Chair

furniture made out of k'nex has always fascinated me, that's what motivated me to make this chair out of k'nex.

So let's get to business:
1: it can hold people up to a 100 kilogram (and maybe even more, but I haven't tried).
2: I think it sits quite comfortable.
3: It looks nice.
4: As you see in the second picture it's got quite normal distance proportions.
5: It's durable because if it breaks you can fix it easily, but you can't with a normal chair.

1: Sometimes the connectors on the rear end snap out, it has no consequences though.
2: the back is not incredibly strong, you can't lend back with too much force.

PS: zorry vor bed englisch, i vrom holland.

Step 1: The First Leg

in this step you'll make the first leg,
it might seem the same as all the other legs but there are a few differences, you'll need to follow all the steps about the legs.

Step 2: The Second Leg

Picture of The Second Leg

the second leg isn't different from the first leg except for one thing: the blue connecters in the third stage of the leg is on the other side as shown in the picture.

Step 3: The Third and Fourth Legs

the third and fourth legs are slightly different from the first two but they are exactly the same as each other.

Step 4: Assembly

In this step you'll assamble the legs.

Step 5: Making the Support

make these parts for more support

Step 7: Even More Support

follow the pictures and notes to make this.

Step 8: The Rear End

dit is echt mooi ik heb hem meteen gebouwd. (helaas zaten er al mijn Knex stukjes in dus hij is alweer stuk).

maisonator (author)2015-01-31

Just a suggestion put arm rest and then support the rear part by building trusses that connect to the arms it will support it

DRAKAMAG (author)2014-07-09

I ran out of peices

Killer~SafeCracker (author)2009-10-18

Check out this chair, man. I think this could hold almost anyone.

that thing lookt awesome. But man, that guy has a lot of knex: A chair, a ferris wheel and that looks like a ball machine in the background

kiffer360 (author)Mr. Muggle2009-10-26

That guy also has quite a lot of time on his hands. Or maybe he works for the knex equivalent of Legoland. 

Mr. Muggle (author)kiffer3602009-10-27

does that exist?

DRAKAMAG (author)Mr. Muggle2014-07-08

knex and Lego actually do have a connection like where pieces are made and instructions too they also have competitions for building and designs and strength check out for more info

I really don't think so. but who knows??

kiffer360 (author)Mr. Muggle2009-10-27

I dunno. There has to be some sort of competition, though. 

Jesus. (author)Mr. Muggle2010-04-18


Hiyadudez (author)Mr. Muggle2009-10-18

Unfortunatley that is only the Big Ball Factory in the background.

Mr. Muggle (author)Hiyadudez2009-10-20

yeah, and the ferris wheel is just the six foot ferris wheel, also made by the k'nex company

Hiyadudez (author)Mr. Muggle2009-10-20

Yeah, but the chair is awesome.

Yes, yes it is.

I know this is completely off topic and all, but look at the knex ball these guys made!

DJ Radio (author)Hiyadudez2009-11-21

Now all they need is a ball machine.

Hiyadudez (author)DJ Radio2009-11-21

Lol, they would need 100's of thousands of pieces to make a ball machine for that thing.

Well that picture was taken at a show in Japan. I believe that each thing was from a different person.

South korea.

Ok thanks, I wasn't sure where it was.
BTW: I'm working on getting those pictures for the office set.

What about Walter Hudson?

Annix15 (author)NYPA2011-12-12

matters if he can even fit in the chair xD

Owenmon (author)NYPA2011-04-02

ooh dats flaaged, i feel sick

peepee4 (author)NYPA2010-04-25


Killer~SafeCracker (author)NYPA2009-11-11

If he could fit in it it might.

NYPA (author)Killer~SafeCracker2009-11-11

It can hold a TON (literally) of weight?

Killer~SafeCracker (author)NYPA2009-11-11

I think it could.

NYPA (author)Killer~SafeCracker2009-11-11


Killer~SafeCracker (author)NYPA2009-11-11

Yes, maybe.

NYPA (author)Killer~SafeCracker2009-11-11

Ok, haven't you had pieces broken by force of the ram? If so, that force is under 100 pounds. Fast moving low force and slow moving big force are two different things. K'NEX will crack under, Hmmmm, about 200 MAYBE 300 pounds. It doesn't matter the structure, it matters the material, in this case.

shooby (author)NYPA2009-11-13

Actually, the structure does matter.  If the pieces form a truss, then forces in each piece will be strictly axial (that's the definition of a truss).  If it is not a truss, then bending will occur.  You're saying that the bending, crushing, buckling, and stretching (tensional)  limits of all k'nex members lies within a 100 pound range, and with a respective maximum difference of 150%?? That makes no sense!

A 10 ft long douglas fir 6x6 column can hold 27,000 pounds without buckling. 

A 10 ft long douglas fir 4x6 column can hold 12,000 pounds without buckling.

So that's more than a 100% difference in bearing capacity, with less than a 150% difference in cross sectional area.

Goed geontwerpt, 'k vind het stoel prima, maar het zou wel iets breeder kunnen zijn.  Als het verticale een beetje slap is, moet je het maar iets breed maken.

Mr. Muggle (author)shooby2009-11-27

oh, het probleem is vooral de rugleuning, die buigt door, ik denk dat de stoel wel meer dan 100 kilo kan houden alleen de rugleuning niet, Trouwens: Ik wou je vragen om lid te worden van mijn groep voor hollanders. Nog een ding, Ik had niet gezien dat je gereageerd had op de stoel want je stuurde een reply naar NYPA,  dus sorry voor de late reactie

Killer~SafeCracker (author)NYPA2009-11-11

Okay, after re-looking at it I see that it won't hold 1,972 pounds. And that is because of the leg structure. If they filled in the bottom of the chair and make it "flush" with the ground I can see it happening. Also that chair shown can hold more than 300 pounds. There is no doubt in my mind. I know a little something about structure. I once built an 18-gram balsa wood structure that held 500 pounds.

NYPA (author)Killer~SafeCracker2009-11-12

I meant the K'NEX will break or the connections will fail.

Killer~SafeCracker (author)NYPA2009-11-12

 Yes, I under stand. But that depends on the structure design you use.

dang!they have a knex muesam? :D

bloody hell =o


Let's turn that Ferris Wheel into an MG.

fries123 (author)An Villain2011-04-16

I have that ferris wheel. I should try that sometime

An Villain (author)fries1232011-04-17


wow I think that can take 1ton!
That is cooooooooooooooooooooooooooooooool you should put that on your home page I would give you 5/5!!!!!!!!!!!!!!!!!!!!!

 what is that? like over 3,000 pieces on that chair???

My fingertips hurt just looking at that....

My younger brother an I have made a nightstand or two before, but THIS.... Is bordering insanity.... no, wait, if it was designed to be modular, I could not only rearrange furniture, but I could also reBUILD the furniture. Can you say "fouton meets laz-e boy meets kitchen stool meets sofa meets jaqouzy(sic)"? And have an electric motor run the transformations, 'cause I'm lazy....

Wait, a theme song comes to mind...
Transformer furniture, more than meets the, ahem, rear end. Nevermind, bad joke, it only made sense in my head, forget it.
