- Dynamic Lumbar (1.7" travel):the lower-back support moves with you as you shift, instead of fighting you.

- 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.
Why it works
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.
Adjustable Headrest
Rises 2.4 in and tilts up to 43° to cradle your head and neck through long sessions.
Mesh + Dynamic Lumbar
1.7 in of lumbar travel moves with you, while breathable mesh keeps you cool all day.
2D Armrests
Raise them 3.3 in and slide them 1.6 in, so your forearms always land in the right spot.
Stable 5-Star Base
A 27.6 in nylon base with smooth PU casters and a 4-position tilt lock keeps you steady.
