401 Series Office Chair

Among the 401 series office chairs, the Sihoo M18 - 401 swivel chair stands out with its multiple outstanding features. Here is a detailed introduction:

Support Design

• Triple Back Support: It adopts a triple spine-relieving design that provides comprehensive support for the cervical spine, shoulders, and waist. During long hours of office work, this all-around support can effectively disperse body pressure, reduce the soreness caused by prolonged sitting, help the user maintain a relatively comfortable sitting posture, and enhance the office experience.
• Multi-Dimensional Rotating Headrest: It can be adjusted according to the natural curve of the neck, precisely fitting the neck and relieving neck pressure. During rest or office work, it offers good support for the neck, preventing neck fatigue and injury.
• Seat Cushion Zoned Pressure Relief: The seat cushion has a zoned pressure-relief function, providing reasonable support for the legs, buttocks, and tailbone. Different areas are designed according to the characteristics of the corresponding body parts, ensuring even force distribution across the body, reducing local pressure, and improving sitting comfort.

Armrest Design

The armrests have a curved design, increasing the contact area with the arms and making arm placement more natural and comfortable. With an adjustment range of up to 7 centimeters, users can easily adjust the armrest height according to their own needs and office scenarios to meet different usage postures, such as typing and reading.

Overall Characteristics

• Sturdy and Durable: The overall weight exceeds 20 kilograms, and the structure is sturdy, capable of withstanding significant pressure and weight without wobbling or being easily damaged. At the same time, the chair meets standard certifications, ensuring reliable quality and allowing users to use it with confidence.
• Versatile Functions: It has a reclining lock function with two angle options. Users can adjust the tilt angle of the chair according to their own needs for short breaks or relaxation. In addition, it features a hidden footrest design that can be extended and retracted freely. During rest, the footrest can be extended to allow the body to relax more fully.

Installation Points

When installing the 401 chair, pay attention to the installation of the screws on the bottom crossbar. Ensure that the screws are tightened to guarantee the stability of the chair's structure. Align the wooden plug holes to connect the components accurately. Place the seat cushion correctly to avoid affecting the comfort of use and the overall performance of the chair due to improper placement.
