Most chairs support your lower back. The X2 Pro's four-panel backrest supports all of it -- upper, mid, and lower, each panel moving independently with you. QuadSync 4-panel backrest. Wrap-around support that conforms to your whole spine instead of pressing on one spot. Dual-zone floating lumbar. 360° adaptive tracking plus a 12° forward tilt closes the gap at your lower back -- even when you lean in. 17 points of adjustability. Including 6D armrests with 20° vertical tilt and full 360° rotation, seat depth, seat forward tilt, and a lockable recline with retractable legrest. Built like it costs. Aluminum-alloy (ADC12) frame, triple-layer wear-resistant mesh, Class 4 gas lift, 330 lb rating, BIFMA + TüV verified, up to 10-year warranty. For anyone comparing the best office chair for chronic back pain, a premium ergonomic mesh chair, or a reclining office chair with legrest and adjustable lumbar support, the X2 Pro is the flagship pick. Its four-panel ergonomic backrest and dual-zone dynamic lumbar system deliver full-back posture support through long workdays -- a genuine step up from single-panel desk chairs at any price.Not sure you need this over the H2 Pro? if your back pain shows up in more than one spot, the X2 Pro's independent panel support is exactly what it was built for.
