Instead of a separate cushion you slide up and down, the X-shaped lumbar support is woven directly into the backrest structure. It pushes back where your lower spine needs it most while leaving your shoulders completely free, so your posture stays natural rather than forced into one stiff position over a long day.

Yes. The Air Mesh used on ErgoChair Ultra 2 is 3 to 5 times more breathable than standard mesh, which means heat and moisture move out instead of building up behind you. After a full workday you'll notice the difference — your back stays dry rather than that uncomfortable clammy feeling you get with denser materials.
Most office chairs use a single foam layer that compresses unevenly over time. ErgoChair Ultra 2 uses a 4-layer system — breathable mesh on top, memory foam, TPE, and a spring matrix underneath with 62 nodes and 186 struts. The result is pressure distributed evenly across your seat bones instead of concentrating in the spots that get sore first.
The backrest has flexible ribs built into the frame instead of a rigid panel. When you shift forward to type or lean back to think, the ribs flex with you and keep the surface aligned with your spine's curve throughout the movement. You stop fighting the chair and it just follows you.
Yes. The seat height goes from 18 to 23 inches, seat depth adjusts from 18 to 20.5 inches, and the chair supports up to 320 lbs. If you add the headrest, total height reaches 58 inches — enough to properly support a taller spine without the headrest ending up awkwardly at shoulder level.
You can adjust the headrest position, armrest height (7 to 11 inches), back tilt angle and tension up to 25 degrees, seat height, and seat depth. Each adjustment targets a specific point where bodies differ from each other, so the chair fits your proportions rather than approximating them.
It's available with or without. If you regularly feel tension in your neck or upper shoulders during calls or long focus sessions, the headrest gives those muscles somewhere to rest without pushing your head forward at an angle. If you tend to sit upright and move around a lot, the no-headrest version keeps things cleaner.
Yes, if you sit more than 6 hours a day. The Pro is a solid chair, but the Ultra 2's adaptive backrest flexes differently and the 4-layer seat handles extended sitting noticeably better. People who switched consistently mention their back feels better at the end of the day — which is exactly what an upgrade should deliver.
Onyx Black and Dover Gray. Both use the same Air Mesh material and frame construction — the choice is purely aesthetic depending on your workspace setup.
320 lbs. That's higher than most chairs in this price range, and combined with the seat depth adjustment, it makes ErgoChair Ultra 2 one of the more accommodating options for people who've struggled to find a chair that actually fits their build.
