Most Adirondack chairs come in pre-cut and pre-drilled kits, making assembly straightforward. The assembly process typically involves attaching the seat, backrest, and armrests with screws, which can be done using basic hand tools. Instructions are usually clear, but it helps to have a second person assist, especially with heavier materials like wood. Some models arrive fully assembled or require minimal effort. While assembly can vary depending on the design and manufacturer, most people can put together an Adirondack chair in under an hour.
