There is none. The whole backrest is the lumbar. For forty years, chairs have asked you to dial in a knob in your lower back you cannot see, against a curve you cannot measure, until something feels less wrong. ErgoChair Ultra 2 flexes the entire back instead — 62 nodes, 186 struts, no setting to get right because there is no setting.

Yes. The 25-degree tilt range and adjustable tension let the chair move with your weight instead of fighting it. Set the tension light if you like to rock while thinking. Set it firm if you want the chair to hold its position when you lean. Either way the back flexes with you, not against you — the exoskeleton is engineered to move, not to lock.
Four directions: up, down, forward, back, plus inward rotation. Height range 7" to 11." The point of an ergonomic office chair with adjustable arms is that one position carries across tasks. Typing, gaming, calls — set them at elbow-90 on day one, the chair holds that geometry whether you are leaning in or back.
The seat pan slides 2.5 inches — from 18" to 20.5" deep. That range is what a 6'2" user needs that a 5'6" user does not. Without an office chair with adjustable seat depth, one of them is always perching and the other is always cut off behind the knee. Two fingers of clearance behind the thigh is the target either way.
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.
Most desks are between 25 and 32 inches tall. The seat lifts from 18" to 23." Buy an office chair with adjustable height in that band and a 5'0" user clears a low desk while a 6'4" user clears a 30" surface from the same chair. Feet flat, knees at 90. If your desk is fixed, the chair meets it. If your desk moves too, set the chair once and forget it.
Yes. The mesh is TPE, not the soft polyester mesh that bags out after eighteen months on most office chairs. TPE keeps its tension under load and breathes about five times more than standard mesh, which is why long sessions stop feeling like a sweat trap by hour four. Lifetime warranty on the frame and mechanism. The ergonomic chair is built to outlast three of the cheaper ones you would otherwise replace.
