Atlas Ergonomic Office Chair — Adjustable Headrest, Dynamic Lumbar
Your neck shouldn't clock out before you do. Eight-hour days pull your head forward, flatten your lower back, and leave your shoulders carrying the slack. The Atlas is built to carry it for you.
- Integrated Adjustable Headrest: one-piece head & neck support with 2.4" horizontal adjustment plus 43°/40° tilt — holds your posture through the longest sessions.
- Dynamic Lumbar (1.7" travel): the lower-back support moves with you as you shift, instead of fighting you.
- Backrest Height (2.8"): dials in for bodies from 4'11"–6'3" — fits the whole household or team.
- 2D Armrests: adjust up/down 3.3" and slide forward/back 1.6" — your forearms land right for typing, reading, or leaning back.
- Breathable Mesh: abrasion-tested to 12,000 cycles, stays cool from 9am to 5pm.
- Built to Last (300 lb / 136 kg capacity): reinforced nylon-fiberglass back frame, 27.6" nylon base, and a SAMHONGSA class-3 gas lift.
Choose with or without the integrated headrest, in Black or Grey.
