Smooth rocking curves and front and rear anti-tip stoppers work together to keep this outdoor wicker rocking chair stable as you move, while anti-slip rubber strips help the runners grip the floor. The PE rattan and metal frame holds up to 400 lbs and is built for long-term outdoor use. An ergonomic triple support design works with the 21.5-in back cushion to cradle your upper body and reduce spine pressure. The 5-in thick lumbar pillow reinforces your lower back so you can sit more comfortably for longer. A 22.5-in deep seat cushion with soft sponge filling gives you ample resting room, and fixing ties keep the cushions from shifting. Washable seat and lumbar cushion covers simplify outdoor maintenance and help keep your porch, deck, or patio seating fresh.
