X3 incorporates most of the same design and features as X-Chair 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.
Q: Does this come with a memory foam seat or the standard molded foam?
A: It is the wide memory foam seat. Pictured below, is my X3 ordered through this link with upgraded wheels and elemax back massager/heater/cooler. The wheels that come with the chair at this link do not roll well on hardwood at all. The upgraded wheels are a significant improvement. The great thing about ordering from Best Buy is the return policy. I sat in the X3 a couple times at the local relax the back store, but I was concerned it would be different when I sat in it for 8+ hours. I didn’t want to risk not being able to return it or it costing a 25% restocking fee. I ordered from Best Buy, and once I was sure I wanted to keep the chair, I ordered the wheels and elemax accessory.
