The flexible woven back is constructed of a special webbing tape developed with DuPont for the Webb Chair Series. The body of the tape was chosen for resistance to staining and abrasion, cleanability, ease of dying, and colorfastness. The elastomer component (DuPont LYCRA spandex) is wrapped with the two-ply polyester and adds superior, long term performance and resilience. This combination of materials conforms with the user s movements in a new way that attains the highest level of comfort. Custom color program is available.
