Why I Built These Chairs

I've been wanting to add some comfortable outdoor seating to our yard in uncovered areas, but it gets to be alot to manage cushions and pillows, trying to keep everything dry, bringing the cushions in when it snows, finding somewhere to store it all ... 

I didn't want to go with plastic chairs, as they blow away in the wind, and I'm forever chasing them down and eventually, picking up pieces of plastic and throwing them away.

So I thought, what if I could build the most comfortable Adirondack chairs ever, that don't need a cushion, that are too heavy to blow away in the wind?

Preparation

Shopping List

3 - 2x4 @ 104-5/8" long (OR 4 - 2x4 @ 8 feet long or 92-5/9" long)

1 - 1x10 @ 10 feet long*

4 - 2-1/2" Kreg Pocket Hole Screws

24 - 2-1/2" long self tapping exterior screws (look for the screws with the star bit heads, can be up to 3" long)

30 - 1-1/2" long self tapping exterior screws (same type as the longer screws, can be slightly shorter or longer (up to 2"), these screws are just used to attach the seat boards to the frame)

*If building more than one chair, you only need 9 feet of 1x10 boards per chair.  So for two chairs, you could purchase one 8' long 1x10 and one 10' long 1x10.

5 - 2x4 @ 19-1/2" - legs and horizontal supports

2 - 2x4 @ 31-3/4" - arms

2 - 2x4 @ 33-1/4" - both ends cut at 20 degrees off square, ends ARE parallel, long point to short point measurement

2 - 2x4 @ 32-3/4" - back supports

2 - 1x10 @ 22-1/2" - seat

3 - 1x10 @ 19-1/2" - back 

Cutting Instructions

It may be easier to pre-finish your boards before cutting.

Tools
Tape Measure
Speed Square
Pencil
Safety Glasses
Hearing Protection
Kreg Jig
Drill
Circular Saw
Miter Saw
Power Sander
General Instructions

Work on a flat level surface.

Instructions

Step 1

As shown in the video, cut the chair stringers at a 90 degree angle at the foot of the stringer with a circular saw.

Build the arms with the 2-1/2" long screws and exterior wood glue.

Make sure the two arms are built the same but in mirror as shown in the diagram.

Step 2

Drill two 1-1/2" pocket holes on both ends of two of the 19-1/2" long 2x4s.  Attach with 2-1/2" screws to the Adirondack chair frame.

Step 3

Lay the seat boards on the 2x4 frame and attach with three 1-1/2" long screws per end of each 1x10 to the seat frame.  Leave about 1/4" gap in between the seat frame for water drainage.

Step 4

Place the remaining 2x4 @ 19-1/2" long under the back of the chair as shown in the diagram.  

Place one seat support in the chair and hold flush to the bottom of the stringer.

Attach with screws to the stringer and to the back support.

Move to the other side of the chair and repeat with the second back support.

Remove the 2x4 @ 19-1/2" long.

Step 5

Attach the 2x4 @ 19-1/2" to the base of the chair with screws.

Step 6

Starting at the top and working downward, attach the seat back boards to the back of the chair.  Make sure you leave a gap at the base of the back to allow for good water drainage.  Evenly split the gaps for best visual presentation.

I'm beginner in the wood working field and have just completed my very first project following one of your post and built two Modern Adirondack Chairs. Wife and kids really love it and are asking me to build more.

I am about to build one of these, love thew look of the 1x10" but alas in my area nobody sells 1x10", has anyone given any thought to building this with 1x8" lumber?

I'm replying to my own post, faux pas I know, but my local lumber retailer lied to me, they have 1x10's, they just didn't know that modern lumber doesn't adhere to true length and width, scary yes?

Hi, I love the design of these chairs and am planning to build a couple. I noticed some people have added posts to reinforce the backrest. Do you think the original design is sturdy enough for kids/adults to sit on the armrests?
thanks!

For all those asking about the stain colour, I was able to replicate ( as far as I can tell from a picture, by a light burn, sand, and then an application of a clear wood sealer. Also, through a happy accident I achieved a few degrees of less incline through putting the back support 2x's @ 90 degrees out from plan, so if you are looking for an easier exit chair, this may help, though it does look bulkier. I stained my first chair a black brown semi translucent, i wiped it on, then wiped it off, which I think looks a bit heavy for the Rustic Modern design, love to show but have no idea how to post pics on here so no go.
Im about to embark on my second chair with a few minor tweaks, 45's on the arm fronts, ditto on the back, 2-4" wider to accommodate us big ol' Alberta Boys, one more section higher. again for us big ol' boys, and the modified Shou-sugi-ban on the seat facings. I'm thinking with the awesome plans that Ana has provided and a few unnecessary but form based tweaks I will be able to, as a total amatuer (with subgrade equipment) be able to build something worthy of any firepit.
