Cut your boards and dry fit together. Finish the boards to seal all edges and to make finishing easier (it would be very difficult to paint your chair as a finished product). Work on a clean level surface. Check your project for square as you go along. Predrill and countersink your screws, using glue on all permanent joints. Work safely.
Cut your stringers as shown above.
Fasten the front apron to the fronts of the stringers as shown above.
Well, you found it! My most favorite Adirondack Chairs! I can't stop building these! So simple, so easy to build, yet amazingly comfortable!
Special thanks to Fiona and Lael for sharing their amazing photos.
Fasten the seat slats as shown above in the diagram, using 2″ screws and glue.
Build the seat back as shown above, using 1 1/4″ screws and glue.
Assemble the seat and back as shown above. Remember that the seat back sits at a 90 degree angle from the seat.
Cut the front legs at 15 degrees off square on both ends, so that the ends are perpendicular. Mark as shown above in purple. Then from the inside of the seat, fasten the legs to the aprons.
Cut your arm supports with both ends cut at 15 degrees off square, ends are parallel to each other. Fasten to the top edge of the legs and to the seat back as shown above.
Attach your arm rests to your arms, using glue and 1 1/4″ screws.
FINISHED TOP EDGE
If you have a Kreg Jig™, you could easily finish the top edge of the back as shown above by simply moving the back top support board to the top.
This chair plan can easily be converted to a five foot long sofa with just a few quick steps. I really love this styled sofa.
You will need to cut 10 more back slats and add 40″ to the length of the seat slats, front apron, and back supports. Of course, you could make your sofa shorter, but I would not go any longer.
In addition, you will need to add supports under the seats as shown above. Make sure you also screw from the seat slats into the supports.
You should also add back support in the form of strong backs between the arms on the back to keep the back from pushing backward.
And of course, you can trim the top out all cute and such!
