Step-by-Step Instructions

Step 1: Cut the Pieces

Cut all parts according to your plan. Use sandpaper or a sander to smooth out edges. Accuracy is key for balance and comfort.

Step 2: Assemble the Sides

Attach front and rear legs to seat supports to form two symmetrical side frames. Ensure the rear legs are angled slightly for that iconic laid-back look.

Step 3: Attach the Seat Slats

Lay the frame on its side and install the seat slats evenly, using wood glue and screws. Space them out for ventilation and rain drainage.

Step 4: Install the Back Slats

Screw the back slats onto the back support rail, then secure the assembly to the rear legs. Maintain even spacing and symmetry.

Step 5: Add the Armrests

Position the armrests flush on top of the legs and fasten them securely. For added support, you can reinforce with angled brackets or wood blocks.

Step 6: Sand and Finish

Give your chair a final smooth sanding. Then apply your favorite wood stain, paint, or a waterproof outdoor sealer.
