The IU79PD is the perfect complement for Intensive Use applications that require an extra measure of toughness and reliability. Built with a heavy-duty structure and upholstered with memory foam in the seat, and a special selection of high double-rub count fabrics, the tall back IU79PD and its little brother, the IU76PD are both ideal for any heavy use environment. However, what really takes both of these chairs to another level is the special layer of tough ballistic nylon that is applied over the lower half of the backrest surface. This highly abrasion-resistant material is the same type that is used by luggage manufacturers because of its industrial strength. Combine an IUPD model with optional fold-away JRPD arms, and you have something truly remarkable. Perfect for 911 call centers, police stations, and other specialized environments. *IUHD Series designed to accommodate users up to 350 pounds
