Anyone who's ever sat in the low-slung seat of an Adirondack chair and sunk into the curve of the fanned back knows there's no cushion-free seat like it. You'll see how some of the parts do double duty, making it a simple build. The beefy seat supports are also the back legs; the wide armrests (perfect for resting a picnic plate or cocktail, by the way) also hold the back support.
Assembling a basic one will take less than a day, if you follow the plans we show here. See How to Build an Adirondack Chair
to see how you can make yours just in time for 4th of July.
