Split Chair by Daniel Lorch

At DMY Berlin this week designer Daniel Lorch will present a chair made by splitting a steel tube and peeling back the legs.

Called Split Chair, the backrest and four legs are made from a single tube, with a sheet-steel seat slung over two cross-bars between them.

DMY Berlin opens 9-13 June.

Here's some more information from Lorch:

Split Chair

During the last couple of months I have intensively studied the design of steel-tube furniture between 1920 to 1940. With the Split Chair, I intend to develop further the classic tube bending construction on the basis of today’s technology. Through the bridging of traditional tube bending with newest 3D laser-technology, a new construction, which stands for material efficiency and self-evident design, became feasible.

    I like the idea of the split tube yet I’m slightly let down by the fact that the back leg appears to be welded on which, for me, makes the idea less credible and the split tube idea decorative. I feel that there would be alot of movement (twisting) in this structure and the welds and fixing points will eventually be susceptible to breakage especially those where the tube is joined. If the welds aren’t perfectly made then any imperfections will be amplified and eventually lead to a catstrophic failure. Good luck.

  • Taking into consideration the above comments, the chair still has a great concept behind it. I am thinking from a sustainability point of view; it uses little material, what looks to be the same all over and by the looks again can be dissembled. I love the idea of the ‘slice’ making a chair. I think if the back legs are developed a bit further it would sing wildly!!

  • Well, I don’t think the tubes are welded, I belive is a single tube splited by half, but I don’t know how rigid can be. I’m agree in giving the back legs some height to render the chair more stetic and more personality.

    i’m not so choked by the back legs, that’s a part of the concept, and that’s make a great division of the tube (back//front), the petition bothers me more with his presence that appears as a supplement and not as a part of the chair, while the rest is smooth and comes in one piece. It appears to me like a parasite.

    but that’s my point of view…really really great work! congrats

    I would guess the tubes are welded as there is no deformation in either of the bends. That would suggest that they were both filled and bent seperately. No?

  • JJ

    @Elina: No.

    This chair is not sustainable. I had the same thought initially.

    For the same weight of steel used, tubes are structurally much stronger than halved tubes. Also, clearly, part of the halved tubing is cut off due to it’s excess length.

    Additionally, where full tubing is used, it can later be cut from the chair and re-purposed, while the halved tubing has far less uses.

    Concept and process are “cool”, but what the designer is really doing here is taking a strong material and sabotaging it.

  • In the last photo you can clearly see the back leg detached, but I’m assuming the back leg is an actual offcut from the rest. So the question becomes does it make it any less credible if the product must bastardize its concept for the sake of production, if the final looks seamless? Fun argument, and for me the answer is no. I would need to see it in person but from here it’s a winner.

  • Leendert

    It’s a great and timeless design. About the manufacturing; I’m quite certain the tubes are welded. I can’t see how you can otherwise easily bent the slices that will make the back legs this way, because not only do you have to bend the tube right behind the starting point of the laser, also you have to straighten the slice where it was bend in the first place. You can better bend the “back leg” tube as a second part and slice it also in half. Then weld it together, and with some grinding and sanding, it looks as one part. But I think you dont have to worry about the welding, it not so difficult to make it as strong as the surrounding material. I have to admit that the construction don’t look very rigid to me, for instance the tube could maybe be a bit bigger in diameter.

  • M. Zalu

    I think it is an interesting concept, but there are some aspects of it that I think need to be considered a little more thoroughly. Firstly, though the previous comment mentions that it looks like it can be disassembled, I am not sure how it could be since it is a split tube. Since it cannot be disassembled it would mean more difficulty in packaging and transportation. Secondly apart from a classic, and sleek call back to steel furniture, I am not sure how this is adding to our corpus of knowledge or design lexicon. Lastly, I found this very reminiscent of a walker.

  • angry catalan

    The back leg is not welded on.

  • karl

    I would agree, with derek that the back legs are welded on. Perhaps in production they would not need to be. It is a nice idea nonetheless. I would like to see a little colour in the chair however, that is a completely personal choice.

  • well at the end, bend it or welded, the final product looks good to me, it has an army look, but I’m also agree with Mick with his comento of being a suplement… also what M. Zalu said about the packaging, its very true that instead of an advantage in the design they have create a problem withe the packaging, that its importan on any production. good luck to all

  • joe

    think its a great chair! the right thickness of pipe will make it strong and sturdy enough, e.g. the revolt chair works perfectly. and regarding transport it looks like it could work as an inside stacker and be transported that way. one thing i am missing though is the rubber/plastic at the bottom of the legs to not have to scratch up the bottom of the legs when sitting on it/moving it. look forward to seeing it at dmy today

    A real achievement. An elegant explication of form. Bravo.
