A proven favorite, the Marathon Series was designed to provide the ultimate contour fit with integrated lumbar and thoracic spinal support, and extensive personal adjustments. Our flagship multipurpose task chair, the Marathon has been specifically engineered to support virtually all users between the 5th and 95th percentiles. Classic stitching details compliment the choice of six available seat sizes, with High Resiliency or Energy Absorbing foam options. The same care to stitching is applied to the sculpted back, which is available in two sizes. Choose the “fixed lumbar” option and your Marathon chair comes with an enhanced lumbar support that is soft, yet supportive.
