Operating Instructions
Your EUREKA ERGONOMIC chair offers several adjustable features to customize your seating experience:

- Backrest Recline: The backrest can be adjusted between 98° and 130°. Use the recline lever (typically on the left side) to unlock the backrest, lean back to your desired angle, and then push the lever down to lock it in place. The chair also features 23° of free rocking motion.
- Headrest Height Adjustment: The headrest can be adjusted vertically by 2.4 inches to provide optimal neck support. Gently pull or push the headrest to set its height.
