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 (memory foam optional) 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.
