The ZUSANA™ Chair by ERGOBOND® is an office chair designed for comfort and adjustability, with a weight capacity of 300 lbs. This instruction manual provides detailed steps for assembly and highlights key functional features of the chair.

Function Description:

The ZUSANA™ Chair is engineered to provide ergonomic support and adjustability for various user preferences. Its primary functions revolve around seat and back adjustments, allowing users to customize their seating experience for optimal comfort and posture.

Usage Features:

The chair offers several key usage features that enhance its ergonomic value:

• Back Knee Tilt: This feature allows the user to adjust the tilt of the chair's backrest. Pulling the lever out locks the backrest in a desired position, while pushing it in enables a free-flowing knee tilt motion, promoting dynamic sitting and reducing static load on the spine. This mechanism is crucial for users who spend long hours sitting, as it encourages movement and helps maintain spinal health.

• Tension Adjustment: The chair includes a tension adjustment mechanism, which allows users to control the amount of force required to recline the backrest. This is particularly useful for tailoring the chair's responsiveness to individual body weight and preference, ensuring that the recline motion is neither too stiff nor too loose. Proper tension adjustment can prevent sudden movements and provide stable support during recline.

• Up & Down Adjustment: The chair's height can be easily adjusted using a gas spring mechanism. Pulling the lever out allows the seat to move upwards, while pushing it in enables the seat to move downwards. This feature is fundamental for achieving an ergonomic sitting posture, where feet are flat on the floor and knees are at approximately a 90-degree angle, aligning with various desk heights and user statures. The gas spring ensures smooth and effortless height transitions.

Assembly Instructions:

The assembly process is straightforward and involves five main steps:

1. Install Casters: All five caster wheels are installed into the base of the chair. This step ensures mobility and stability of the chair.
2. Install Gas Spring: The gas spring is inserted into the base. This component is critical for the chair's height adjustment mechanism.
3. Install Armrests: The armrests are attached to the base using spacers (c) and bolts (b), secured with an allen key (d). This step provides upper body support and completes the chair's foundational structure.
4. Join Back and Seat: The backrest is connected to the seat using spacers (c) and bolts (a), tightened with an allen key (d). This step brings together the main ergonomic components of the chair.
5. Final Assembly: The assembled body (seat and back) is joined with the legs (base with gas spring). A crucial warning is provided: "be careful when installing the chair on the gas spring." This emphasizes the importance of proper alignment and caution to prevent damage or injury during the final connection.

The chair comes with a comprehensive hardware kit, including:

• M8X20 Bolt (5 pcs) - labeled 'a'
• M8X25 Bolt (7 pcs) - labeled 'b'
