User Guide
Questions About Zenpex?
Part 1 · Product & Fit
Everything about fit, comfort, and daily use.
Is this chair suitable for tall users over 6 feet?
Yes. The chair is designed to accommodate users ranging from 5'3" to 6'3". It features a 2.0" adjustable seat-depth range to provide better thigh support for taller users, plus an adjustable headrest for more comfortable neck support.
How does the "Dynamic Lumbar Support" work?
The OTO Zenpex features a dual dynamic lumbar system that automatically adapts to your posture and the natural curve of your spine. This provides continuous lower back support and reduces pressure during long hours of sitting.
What are the primary materials used in the construction?
The chair uses high-resilience, breathable Wintex M350 mesh across the backrest and seat to maintain airflow. The frame and armrests use durable PA+GF and PP+GF materials, paired with an SGS Class-4 gas lift and a polished aluminum-alloy base.
Can I tilt the chair back for a nap?
Yes. The backrest reclines up to 135° with a three-position recline lock. Combined with the pull-out, flip-up footrest, it lets you move easily from an upright work posture to a more relaxed resting position.
