How to Build an Adirondack Chair: The Complete Beginner's Guide
There is something timeless about an Adirondack chair.
The wide armrests. The reclined seat. The way it invites you to slow down, sit back, and actually enjoy being outside.
It's the most iconic outdoor chair ever designed — and it's also one of the best first woodworking projects a beginner can tackle.
In this guide, you'll learn everything you need to build your own Adirondack chair from scratch — even if you've never picked up a saw before.
Why Build an Adirondack Chair?
Before we get into the how, let's talk about the why.
It saves you serious money. A decent quality Adirondack chair in a store costs anywhere from $150 to $400. Building one yourself costs $35 to $70 in lumber — depending on your local prices. That's a saving of up to 80%.
It's beginner-friendly. Despite its impressive appearance, an Adirondack chair is made entirely of straight cuts. No curves, no complex angles, no advanced joinery. Just boards cut to size and assembled step by step.
It lasts for decades. Store-bought outdoor furniture is often made from cheap materials that warp, crack, or fade within a few years. A chair you build yourself from quality lumber — and finish properly — can last 20 years or more.
It feels incredible. There is a specific kind of satisfaction that comes from sitting in a chair you built with your own hands. You'll feel it the first time you sit down in yours.
What is an Adirondack Chair?
The Adirondack chair was originally designed in 1903 by Thomas Lee in the Adirondack Mountains of New York. He needed outdoor furniture that would be comfortable on uneven, sloped terrain.
The design he created — wide flat armrests, a slatted seat, a reclined back, and four sturdy legs — turned out to be so comfortable and so practical that it has barely changed in over 100 years.
Today it's the most recognized outdoor chair in the world. And it's built from simple, straight boards — which is exactly why it's perfect for beginner woodworkers.
What You Need Before You Start
Tools
You only need 6 basic tools to build an Adirondack chair:
- Circular saw or miter saw — for cutting boards to length
- Drill & drill bits — for screwing pieces together
- Measuring tape & pencil — for marking every cut
- Speed square — for straight, accurate lines
- Sander or sanding block — for smooth, splinter-free surfaces
- Clamps — to hold pieces while assembling
Don't have a saw? No problem. Every WoodPlanShop Adirondack chair plan includes a detailed cutting diagram. Take it to your local lumber store and ask them to cut all the pieces for you. Most stores do this for free or a small fee. When you get home — just assemble.
Wood
For outdoor furniture, you want wood that can handle weather. Here are the best options:
✅ Cedar — naturally weather resistant, lightweight, beautiful grain. Best choice.
✅ Pressure-treated pine — very durable and affordable. Great budget option.
✅ Redwood — premium option, naturally rot-resistant. More expensive but stunning.
❌ Avoid untreated pine or poplar for outdoor use — they will rot quickly when exposed to rain and humidity.
Fasteners
Use exterior-grade screws (also called deck screws) — they're coated to resist rust. Standard interior screws will rust and stain your wood within one season outdoors.
The Anatomy of an Adirondack Chair
Understanding the parts of the chair before you build makes the whole process much easier.
An Adirondack chair has 5 main sections:
1. The Front Legs — two vertical posts at the front that support the seat and armrests
2. The Back Legs — two angled boards that form the rear support and give the chair its reclined feeling
3. The Seat Slats — horizontal boards that form the sitting surface
4. The Back Slats — vertical boards that form the backrest, usually fanning slightly outward at the top
5. The Armrests — the wide, flat boards on each side — the most iconic feature of the design
Understanding how these 5 parts connect to each other is the key to a successful build.
Step-by-Step Overview
Here's how the build works from start to finish — following the exact same steps inside our Modern Adirondack Chair plan.
Before you start — read the full plan first. This is the most important tip. Before picking up any tool, read through all the steps once. You'll understand how each part connects to the next, avoid cutting mistakes, and build with much more confidence.
Step 1 — Assemble the seat frame
Connect the two rear legs to the front seat support board to form the base frame of the chair. Use galvanized or stainless steel screws for all joints — they resist rust outdoors. Check for square frequently as you build the frame. A slightly crooked frame here will affect everything that follows.
Step 2 — Install the seat slats
Attach the 4 seat slats horizontally across the frame one by one. Leave a small gap of about 0.5 inches between each slat — this allows proper airflow underneath and gives the chair its classic clean look. Don't skip this gap — it also prevents water from pooling on the seat after rain.
Step 3 — Assemble the backrest
Build the backrest as a separate unit before attaching it to the chair. Connect the 4 vertical backrest slats to the backrest support rail, then attach the two backrest braces across them. Again — leave a 0.5 inch gap between each slat for airflow and aesthetics.
Pro tip from the plan: position the backrest braces at 3 inches from the top and bottom edges of the slats for a clean, balanced look.
Step 4 — Attach the backrest to the seat
Now bring the two main sections together. Lower the backrest assembly down onto the seat frame and attach it to the rear legs. Pre-drill your holes before driving screws — this is especially important near the ends of boards where wood splits most easily.
Step 5 — Attach the front legs
Attach the two front legs to the front corners of the seat frame. Position each leg so it sits 9.27 inches from the outside edge — this is shown clearly in the plan diagram. Pre-drill all holes here too.
Step 6 — Assemble the armrests
Build each armrest as its own unit first. Place the armrest support (2x2 board) underneath the armrest slat, positioning it 1 inch from the front and 3 inches from the side edge. Secure with screws. Repeat for the second armrest.
Step 7 — Install the armrests
This is the most satisfying moment of the whole build. Place each assembled armrest on top of the front legs and attach securely. The moment both armrests are on — it looks exactly like a real Adirondack chair. 🪑
Take a step back and enjoy that feeling.
Final step — Sand and finish
Do a final light sand over the whole chair with 220-grit sandpaper. Then apply your exterior finish — wood stain, outdoor paint, or wood sealer. Apply two thin coats rather than one thick one. This protects your chair from rain, sun, and humidity for years to come.
From the plan: a high-quality exterior wood sealer or stain will preserve the finish and protect the chair from weather damage.
Total lumber you need for this build:
| Board | Size | Quantity |
|---|---|---|
| 1x6 | 5.5" x 0.75" — 6ft | 5 boards |
| 2x2 | 1.5" x 1.5" — 6ft | 2 boards |
| 2x6 | 5.5" x 1.5" — 6ft | 3 boards |
Plus: exterior wood screws (1.5" and 3"), sandpaper, and optional wood glue and stain.
How to Finish Your Adirondack Chair
The finish protects your chair from rain, sun, and humidity. Here are your options:
Exterior wood stain — enhances the natural wood grain, soaks into the wood for deep protection. Best for cedar and redwood.
Exterior paint — fully covers the wood, available in any color. Most popular choice. Use a primer coat first for best results.
Outdoor wood oil — gives a natural, matte finish. Needs to be reapplied every 1-2 years but looks beautiful.
Tip: whatever finish you choose, apply it before final assembly if possible. It's much easier to coat flat boards than to work around joints and screws.

Common Beginner Mistakes to Avoid
Mistake 1: Skipping pre-drilling Always pre-drill your holes before driving screws into the ends of boards. End grain splits easily. A quick pre-drill prevents cracks and gives a much cleaner result.
Mistake 2: Rushing the sanding Outdoor furniture gets touched constantly. Rough surfaces become splinters. Take your time sanding — it's the difference between a chair people love and a chair people avoid.
Mistake 3: Using indoor screws Regular screws rust outdoors within weeks. Always use exterior-grade or stainless steel screws for outdoor projects.
Mistake 4: Applying finish too thick One thick coat of paint or stain peels. Two thin coats bond properly and last years longer.
