X3 incorporates most of the same design and features as X2 but replaces the X2’s K-Sport material with the latest advancement in fabric technology, Advanced Tensile Recovery Fabric (ATR), a high resiliency molded foam seat and a full polished aluminum frame. In addition, ATR is water, spill and stain resistant, meaning your chair will continue to look good as new for years to come. When you feel the ATR difference you will wonder how you ever were satisfied with traditional fabric.
Advanced Tensile Recovery Fabric - Drawing its inspiration from modern material designs and ancient buttressing principles, ATR is a woven multilayered nylon that is both responsive and supportive. Comparing to traditional fabrics, it has more give and spring and as a result it provides an enhancing layer to the X3’s already remarkable underlying molded seating support surface
