Featured in the essay Make This Chair., the Two by One Chair design was used as a pretext to pursue a discussion on DIY and the modern condition. It requires a minimal amount of materials by utilizing the triangle to both enhance the structure of the chair and define its aesthetic (much in the same way Enzo Mari and Tord Boontje did with their DIY designs). The full assembly process takes about 2 hours to complete and the parts cost less than 20 USD on average.

  1. Love the Two by One chair. Do you keep the screws exposed? What about deeper countersinks and then tap in wood caps? Might that lose some integrity of the connection?

    PS. I did an Enzo Mari type bench for , furniture contest. Pretty good, given my lack of skills. M.

    1. You can definitely use the method you described to cover up the screws – I don’t think it would affect the strength of the connections. An alternative is to use wood pegs and glue to join the pieces together (like in the new chairs on the website). We would love to see the Enzo-like bench – if you would like to share, please send photos to [email protected]

  2. Hello! I love your 2×1 chair and this website as a whole. A quick question: do you have recommendations of optimum 2×1 length to avoid waste? For example… to make one chair, is it better to buy 8 pieces of 2x1x8ft or 6 pieces of 2x1x12ft… or what do you recommend?
    Thank you!

    1. Hi Sergio, Good question – I haven’t done that calculation, unfortunately, but feel free to share here if you’ve figured it out by now. I hope your chair turned out how you wanted!
