Qingjie Free 3.0 Ergonomic Study Desk & Yuying 2.0 Chair Set

Elevate your home office or your child’s learning environment with the Qingjie Free 3.0 and Yuying 2.0 Furniture Bundle. This premium set is engineered to bridge the gap between childhood development and professional adult needs. By combining a precision-engineered manual lift desk with a highly supportive ergonomic chair, Qingjie provides a versatile workspace that adapts as your family grows. Whether it is for intensive study sessions or a full day of remote work, this set ensures comfort, safety, and long-lasting durability.

Key Benefits

Stepless Height Evolution:** The desk features a smooth manual hand-crank system that adjusts the height from 52cm to 75cm. This "stepless" adjustment allows you to find the exact millimeter of comfort, making it a perfect fit for young children starting school all the way through to adults in a home office.

Superior ENF-Grade Safety:** Your health is a priority. This set meets the rigorous ENF safety standards for formaldehyde emissions—the highest tier available. With non-detectable levels (ND) in testing, it provides a safer breathing environment compared to standard E0 or E1 grade furniture.

Expansive 7200 cm² Workspace:** The "full-screen" desktop design offers a massive 7200 cm² surface area. This provides ample room for dual monitors, oversized textbooks, and art supplies without feeling cluttered.

Ergonomic Synergy:** The included Yuying 2.0 chair is designed to complement the Free 3.0 desk, promoting a healthy "90-degree" posture that reduces strain on the spine and neck during long hours of sitting.

Refined Aesthetic:** Finished in a sophisticated default gray, the set offers a modern, minimalist look that fits any contemporary interior. The materials are selected for both their tactile feel and their resistance to daily wear and tear.

How to Use

1. **Assembly:** Assemble the desk frame and chair following the provided structural guide. Ensure all bolts are tightened securely before use.

2. **Height Adjustment:** Insert the manual crank into the designated port. Rotate the handle clockwise to raise the desk for adult office work or counter-clockwise to lower it for a child’s study height.

3. **Ergonomic Alignment:** Adjust the Yuying 2.0 chair so that the user's feet are flat on the floor and the desktop sits at elbow height to prevent shoulder fatigue.

4. **Crank Storage:** Once the desired height is reached, the manual crank can be tucked away to maintain a clean, snag-free profile.

Care & Safety

Surface Care:** Wipe the desktop with a soft, microfiber cloth. For stubborn spots, use a mild, non-abrasive soap solution. Avoid saturated wet cloths.

Load Management:** While the manual lift is robust, avoid placing excessive weight (such as heavy machinery) directly over the crank mechanism to ensure longevity.

Safety Check:** Periodically inspect the manual lift gears and chair tension to ensure everything remains in peak operating condition.
