Tools: Drill / Driver, Pocket Hole Jig. Materials: 2x4, 10 ft, Exterior pocket hole screws, 2-1/2"

Attach the 2x2 seat supports inside the chair frame with pocket hole screws, placing every screw on the bottom or the sides of the joint — never the top, which would cup and hold rainwater against the wood and screw.

Lay out the chair back slats and attach them to the chair-back base frame with the shorter screws.
Set the assembled back inside the chair, leaving a small gap above the 2x2 seat support for water drainage, and attach to the arms with the longer screws.
Tools: Drill / Driver, Random Orbit Sander.
Lay the seat slats inside the chair and attach with the shorter screws, two per joint, with 1/2" spacing between slats.
Sand and finish the whole chair before it goes outside.
