Hey there Remodelaholics, Scott here from Saws on Skates. I love designing and building multi-function furniture. (Take a look at my DIY kitty litter cabinet and an outdoor coffee table with four hidden side tables.) My version of Benjamin Franklin’s ladder chair has an updated, modern look, but hints at his original design.

The original ladder chair would have been constructed with mortise and tenon joints, but, thanks to pocket hole joinery, this DIY ladder chair is easy to assemble.

Since you’ll be making a lot of angled cuts and precision is important to this design, I highly recommend you review my tips for adjusting your miter saw for accurate cuts and the best way to adjust a table saw blade for precision cuts. 

TIP: For a tailored, professional look,  I used my pocket hole plug cutter to make plugs to fill the holes. Apply glue to the pocket holes and insert the plugs. Trim flush once dry. Then sand and finish as desired.

  1. Hi!
    I’ve been very glad to find here building plans of ladder chair which is easy to make with my not so advanced woodworker’s skill. But I live in Europe and am not familiar with measures you use. I can convert inches into mm, I can take a ruler with inches – it can be bought in my country, but I don’t understand the description like this – 5/4x2x8. What does it mean? What is length, thickness etc? What is 5/4? 5 feet 4 inches? Main question – what is the thickness of different parts of the chair?
    Please help me!
    Thanks and Happy New Year!

    1. Hi Victor – Greetings from the US! A 5/4x2x8 measures 1-1/8″ thick x 1-1/2″ wide x 96″ long. Hope that helps. Please let me know if you have any other questions and I’ll do my best to help.

      1. Hi Scott!
        Thank you very much! Your explanation is full, I can now convert all dimentions and make this chair. Thanx a lot!

  2. You have an awsome chair ladder and I want to make it… but I believe that you have a mistake in the plans
    At step 21 you have both sides left and right at 22,5degree but the left side is less… Same left angle at step 18 is 5 degree. Correct me if I’m wrong

  3. Bonjour, j’ai été très heureux de trouver ici des plans de construction de chaise mais je n’arriva pas à télécharger. Je vis en France et je ne suis pas familier avec les mesures que vous utilisez, nous utilisons des métriques.
    Pouvez- vous m’envoyer le plan s’il vous plait?
    merci d’avance et bonne continuation!

  4. Hi Scott,
    Thanks for the plans. Love them as they are straight forward and easy to follow. I’m in Australia but don’t follow the sizes. My daughter has asked me to make the chair.
    I note the comment above 5/4x2x8 = 1-1/4″thick by 1-1/2″ wide by 96″ long but don’t know how you got that from the original. I don’t follow the material sizes ( screws etc OK). I can’t work out the thickness of the material. Dis I miss something?
    I can work in inches or mm.

    Thanks

    1. Near as I can figure, 5/4 x 2 x 8 as he indicated was 5/4 = 1 1/8th but that must be the planed dimension because 5 divided by 4 equals 1 1/4 inches. and he uses 1 1/2 inch for the 2., again a planed dimension. Like when we buy dressed 2 x 4’s. That’s my guess. Never seen it written like that before. I grew up in Canada before we went metric.

  5. My interpitation of 5/4 = 5 quaters = 1/14

    Your plans are confusing because you interchange 5/4
    to mean 5 1/8 in one place and 5/4 in another.

    Get a definition from you lowes dealer. If he disagrees tell him to check it out with his lumber supplier
