Extendable Version of Office Chair

Among the Qingxian LiberNovo series of office chairs, the OC1 Pro Extended Version, Omni Extended Version, and OC1 Extended Version all support extended seat depth design, with a seat depth of 48±1cm, suitable for users with a seat depth greater than 48cm.

1. Target Users and Seat Depth Parameters of the Extended Version

The Qingxian LiberNovo OC1 Pro Extended Version is optimized for users with a larger seat depth, with a seat depth of 48±1cm, meeting the needs of taller users or those with longer legs. If a user's seat depth (the vertical distance from the edge of the desk to the anterior edge of the sacrum) is greater than 48cm, choosing the extended version can prevent leg suspension and enhance support comfort.

2. Measurement Method and Version Selection

The official provides a standard measurement process:

• Step 1: The user sits on a hard surface (such as the floor), leaning back completely so that the back of the knee is close to the edge of the desk;
• Step 2: Keep the upper body upright and bend the knees approximately 90°;
• Step 3: Place a hard reference object (such as a book) at the sacrum and measure the horizontal distance from the edge of the desk to the anterior edge of the reference object.
  If the measured value is >48cm, the extended version is required; if ≤48cm, the standard version will suffice.

3. Extended Version Models and Installation Convenience

• LiberNovo OC1 Pro Extended Version: Features dynamic ergonomic design, supports seat depth adjustment, and is suitable for users of different body types;
• LiberNovo Omni Extended Version and LiberNovo OC1 Extended Version: Adopt a whole-unit delivery model, requiring no complex assembly after unboxing. They can be used directly by pushing them away from the packaging box, suitable for users seeking convenience.

4. Design Advantages and User Experience

The extended version reduces pressure on the buttocks and thighs by extending the seat depth, minimizing fatigue from prolonged sitting. The dynamic ergonomic design adjusts the support angle according to the user's sitting posture, further optimizing comfort. For users taller than 180cm or with a relatively large proportion of leg length, the extended version effectively avoids leg compression and enhances office efficiency.

Summary: The Qingxian LiberNovo extended version office chairs provide scientific support for tall or long-legged users through precise seat depth design and convenient installation methods. The measurement method is simple and easy to operate, allowing users to choose the appropriate model according to their actual needs.
