Zenox Ergonomic - Shiho Office Chair
Zenox Shiho Ergonomic Office Chair
The Shiho Ergonomic Office Chair is built for people who spend long hours at the desk and want support that feels natural rather than rigid. With a linked headrest, adjustable head and arm support, a full-height recline and breathable mesh, it helps you sit more comfortably, move more freely and keep your workspace feeling refined day after day.
Functionalities
The Shiho Series uses a TUV certified Class 4 hydraulic gas lift for height adjustment that feels smooth, stable and quiet, making everyday use more comfortable.
The full-height backrest reclines up to 120° and locks at several positions with a simple control under the armrest, so you can move easily between focused work and relaxed breaks.
The height- and angle-adjustable headrest lets different users fine-tune where their head and neck are supported, helping reduce strain across longer sitting sessions.
The linked headrest moves in sync with the backrest as you recline, keeping support under your head and neck consistent instead of drifting away as you lean back.
BIFMA 5.1 Full Chair Certification
The Shiho Series is tested to meet BIFMA 5.1 full chair standards for safety, durability and structural performance. Those tests help confirm that the chair can handle daily office use, provide dependable support and maintain its feel over time instead of softening or loosening too quickly.
Ergonomic Backrest Design
The backrest is shaped to support the full length of your back and encourage a more natural spinal alignment, which can help ease tension across the shoulders and lower back. Unlike a fixed single back, the separated backrests are designed to follow the curve of your spine more closely, offering a more tailored level of support during long sitting periods.
Breathable & Contoured Seating
The seat’s curvature is designed around common pressure points at the hips and lower back, helping maintain a more comfortable posture throughout the day. High-strength mesh allows air to pass through and releases heat more easily than solid foam, which can help you stay cooler and feel fresher during longer sessions.
Customizable Arm Support
Shiho’s 4D armrests can be adjusted up and down, moved forwards and backwards, and shifted inwards or outwards. This flexibility makes it easier to line the armrests up with different desk heights and switch between typing, reading and relaxed postures. When you need more room, you can lower them under the desk to free up space.
Quiet & Smooth Mobility
Premium casters are chosen with shared workspaces in mind. They roll smoothly and quietly across hardwood, tile and carpet, helping you reposition the chair when you need to without adding unnecessary noise or scuffing the floor.
