Unlike traditional Adirondack folding chairs, this model has an adjustable backrest and a folding function. The backrest provides 3 adjustable angles of 100°, 110°, and 120°, so you can freely switch between sitting and reclining. Perfectly fits your body curves. It can effectively reduce the fatigue of sitting for a long time and protect the waist. The chair can be folded for easy storage or portability.
