There are many variations of the classic adirondack chair. This particular version features straightforward construction and common materials. This chair makes for a satisfying project that can be built and finished in one weekend. And when properly finished, it will provide years of comfortable seating.
Cut the back legs (A) to length and lay out and cut the angles according to the detail drawing. Use a jig saw or circular saw and guide to make smooth, straight cuts. Note which cutout pieces you will be saving to make braces later on. Lay out where seat stretchers (B) will be attached according to detail drawing. Drill pilot holes.
Cut seat stretchers (B) to length and attach to back legs according to layout marks with 2" screws.
Cut arms (I) to length and mark where back support (J), front legs (H) and braces (K) will be attached according to detail drawing. Drill 1/8" pilot holes.
Clamp back support (J) in place and attach with 2" deck screws. Trim two of the cutout pieces from back legs to make braces (K) according to detail drawing, and attach them and front legs (H) to the underside of the arms where noted with 3" deck screws.
Measure up from the bottom of both front legs and mark 16". Clamp back leg/stretcher assembly to the front leg arm assembly, keeping the top of the back legs at the 16" mark and the front edge of the back legs flush with the front edge of the front legs. Attach with 2" deck screws.
Cut all other pieces to lengths according to cut list. Lay out your back slats (D, E, & F) with the best sides facing down and ¼" spacers between each slat. Use a straightedge along the bottoms to help with alignment. Drill pilot holes in back stretchers (G) and attach to the back of the slats. Attach bottom edge of the bottom stretcher 4" up from bottom of slats, and the second stretcher 16" up from that.
Set back slat assembly into place, with the bottom stretcher (G) resting on the back seat stretcher (B). With 2" screws attach through the slats (D, E, & F) into the seat stretcher (B) and back support (J).
Drill pilot holes in seat slats (C) and lay them out on the seat with ¼" spacers between each slat. Remove one arm assembly for drill clearance and drill pilot holes into the back legs through your slat pilot holes, then attach with 2" screws. Reattach arm assembly and repeat for other side.
Break all edges and sand all surfaces smooth before applying waterproof finish according to manufacturer instructions.
