This chair is considered the Rolls Royce of office chairs. Designed to fit the natural curvature of the spine and increase circulation. Excellent for relieving lower back pain. Made to sit in for long periods of time. Cosmetically in condition for office use. No tears in the mesh. Some surface marks are evident, but not distracting. No tears in the arm padding. All mechanical functions have been tested and found to be working.
