Office Chair 91103
Admin October 08, 2026
The Deli 91103 is an office chair designed for staff, featuring adaptive lumbar support, breathable mesh fabric, and optimized detail design. However, it has the drawback of a non-adjustable backrest, leading to mixed user reviews.

Core Features
- Adaptive Lumbar Support: Utilizing a hyperbolic design, the upper section precisely supports the lumbar spine, while the lower section effectively distributes pelvic pressure. It automatically adjusts the angle according to sitting posture, providing dynamic support for the waist and reducing fatigue from prolonged sitting.
- Breathable Mesh Fabric: The highly elastic and breathable mesh fabric adapts to different seasons, preventing back sweating in summer and reducing cold sensations in winter. The mesh surface is resistant to liquid penetration and easy to clean. The waterfall-edge design of the seat cushion reduces pressure on the thigh blood vessels, preventing tingling and numbness even after two hours of continuous sitting.
- Optimized Detail Design: The armrests support four-way adjustment (up, down, left, and right), allowing natural elbow placement during typing and relieving shoulder and neck pressure. The silent casters glide quietly on wooden floors, avoiding disturbances to others. The one-touch recline function supports lying down at a 135-degree angle, preventing neck stiffness duringๅไผ (noon breaks).
Drawbacks
The backrest cannot be adjusted forward or backward, which may result in insufficient support for users taller than 180cm, potentially affecting comfort during long-term use.
User Reviews
- Positive Feedback: Some users report experiencing the meaning of "A craftsman must first sharpen his tools" after trying the chair. The lumbar support is strong, enabling them to focus on work even after consecutive overtime shifts until 3 a.m., without feeling waist soreness or dizziness upon standing.
- Negative Feedback: Some users note that prolonged sitting in summer leads to sweating, and the back cushion's supportiveness decreases after extended use, resulting in a less satisfactory sitting experience.
Suitable Scenarios
This chair is ideal for staff who need to work at desks for long periods, especially those requiring lumbar support and with a height below 180cm. If a noon break or multi-angle adjustment is desired, the one-touch recline function can be utilized, but attention should be paid to the backrest adjustment limitations.
