How To Make an Adirondack Chair

two DIY adirondack chairs

When designing an outdoor space that works for you, it’s important to have a place to sit back and relax. There are always lots of garden seating options to choose from, but what about making your own?  

If you’re looking for something a little different, making an Adirondack chair could be the perfect outdoor seating solution for you. 

What is an Adirondack chair?

The Adirondack chair was designed for lounging (and napping). It has a high back, a reclining, sloping seat that allows you to rest close to the ground and extra-wide armrests that provide an ideal place to set your drinks and nibbles on.  

Whether it be for your garden, porch or balcony, making your own Adirondack chair will provide a great backdrop to your space – and its wooden frame can be painted however you like.  

To help you make your own Adirondack chair, we’ve called upon the experts, Triton Tools and DIY enthusiasts, Brothers Make. They’ve put together these amazing Adirondack chair plans, along with a great how-to video, to guide you at each step. 

Before you start: 

As this project requires the use of some power tools, we recommend you take a look at our DIY Safety Tips. Reach out to a certified expert if there’s anything you’re not sure of. 

Here’s what you’ll need:

  1. pieces of cut timber

    Cut your timber lengths to size

    With your 18x144x2400mm timber 

    • A – Back leg x2 – 1190mm
    • B – Front leg x2 – 600mm
    • C – Arms x2 – 815mm
    • D – Mid brace – 624mm
    • E – Rear brace – 624mm

    With your 18x94x2400mm timber 

    • F – Back slat x5 – 790mm (cut a 50° custom corner on 2 of them)
    • G – Front brace – 660mm

    With your 18x69x2400mm timber 

    • H – Seat slat x8 – 660mm
    • I – Arm rails x2 – 5700mm (mirrored)
    • J – Back brace x2 – 660mm (on one, adjust the jigsaw to 10° when cutting the curve)
    • K – Top back brace – 480mm
    • L – Arm support x2 – 90mm
  2. assembling the legs of the chair

    Assemble the legs

    Take the pieces of wood labelled A and B, leaving an overhang of 95mm – and with the underside of piece A being 260mm from the floor.  

    Use a straight edge to ensure the two parts sit flat and attach them together using three screws. Then, make the second leg of your Adirondack chair by assembling a mirror image of what you’ve just done.  

  3. Attach the three braces

    These are parts D, E and G – using pocket holes. You’ll want your Adirondack chair to look its best, so ensure your pocket holes are hidden on the inside.  

    Top tip: Triton pocket hole screws are self-tapping, so there’s no need to pre-drill pilot holes unless you’re working very close to an edge.

  4. drilling together backrest of chair

    Make a back rest

    To do this, attach the centre slat (the first of your F pieces) to the middle-curved braces (J and K). You’ll need to ensure the back brace with the 10-degree angled curve is on the bottom.  

    Then, continue to add the rest of your F slats, working outwards from the centre with a 9mm gap in between.  

    Top tip: A pocket hole plug works perfectly as a spacer. 

  5. securing backrest to chair

    Attach the back rest to the base

    Simply take your drill and screw the bottom brace into the back legs.  

  6. wooden slats for seat

    Attach the seat slats

    Take piece H and secure it to your chair’s back legs (A), using two screws on either end of each slat.  

    Again, use a pocket hole plug as a space in between each slat.  

    Top tip: Pre-drill the holes in your slats about 15mm in from the edges. 

  7. attaching arm rails to chair

    Attach the arm rails

    Now it’s time to secure the arm rails (I) to the front legs of your Adirondack chair, using two pocket hole screws.  

    Next, attach the arm supports (L) to the centre of the outside face of the front legs – these are your B pieces. Keep them flush to the top.  

  8. Attach the arms

    Take your C pieces of wood and attach them using pocket holes through the arm supports (L) and rails (I). 

    To ensure maximum comfort in your Adirondack chair, the arms should overhang the front legs by 70mm. 

  9. sanding the chair

    Sand the chair

    Using 120 grit sandpaper, smooth the surface and edges of your chair. The last thing you want is a splinter interrupting your mid-afternoon nap! 

  10. Apply the finish

    Now you know how to make an Adirondack chair, it’s time to blend it into your outdoor setting.  

    Choose your preferred finish of choice – will you opt for a wood stain or exterior paint colour? 

    Once it’s dry, enjoy a well-earned sit down!
