Setup and Assembly
Follow these steps carefully to assemble your HAPPYGRILL Tall Adirondack Chair. It is recommended to have two people for assembly.
- Unpack Components: Carefully remove all parts from the packaging and lay them out on a soft, clean surface to prevent scratches.
- Attach Backrest to Seat: Connect the backrest to the seat using the provided hardware. Do not fully tighten screws at this stage.
- Assemble Legs: Attach the front and rear legs to the seat and backrest assembly. Ensure correct orientation.
- Install Armrests: Secure the armrests to the side of the seat and backrest.
- Attach Footrest: Connect the footrest between the front legs.
- Final Tightening: Once all parts are loosely assembled and aligned, gradually tighten all screws and bolts using the included Allen wrench. Important: Do not tighten screws until all holes are aligned. Otherwise, some screw holes may be misaligned, or result in different lengths of furniture legs.

Refer to the product dimensions for proper assembly and placement.

Ensure all screw connections are reinforced and secure.

Troubleshooting
If you encounter any issues with your chair, refer to the following common solutions:
