Seven adjustable backrest positions let you move from upright reading to a deeper recline by lifting the armrests, so you can match your posture to sunbathing or relaxing. The anti-rust aluminum frame uses a sturdy triangle structure to support up to 330 lbs while keeping weight to 20 lbs for easier handling. Breathable fabric in the seat and back helps you stay cool in hot weather. A high backrest with a 15 x 6 in neck pillow and supportive armrests relax your upper body, and two bottom wheels plus a folding design make it simple to move and store between poolside, backyard, and patio.
