Smooth rocking comes from the precisely curved frame working with front and rear anti-tip stoppers, so the chair moves gently without sliding backward. Anti-slip rubber strips help the base grip hard surfaces on a porch, balcony, patio, garden, or backyard. An ergonomic triple-support design, 21.5-in back cushion, and 5-in thick lumbar pillow cradle your spine and lower waist. The 22.5-in deep seat cushion with soft sponge padding offers room to stretch out, and fixing ties help keep it in place. Hand-woven PE rattan over a sturdy metal structure holds up to 400 lbs, while washable seat and lumbar covers make routine outdoor care easier when you avoid prolonged rain exposure.
