Key Features

• Bionic Shell-Back Design: The seat and backrest form a single, seamlessly curved shell inspired by the natural contours of the human body. The gentle curvature cradles your back and distributes pressure evenly, reducing fatigue during extended sitting.
• Ergonomic Spine Support: The slight curvature of the backrest surface is calibrated to match the natural S-curve of the spine, providing attentive lumbar and upper back support that helps maintain good posture over long study or work sessions.
• 12 cm Height Adjustment Range: The SGS-certified 3-stage pneumatic gas lift allows smooth, tool-free height adjustment over a 12 cm range, making it easy to align the chair with desks and tables of various heights.
• 105°–120° Adjustable Recline: Lean back for a moment of rest or tilt adjustment between 105° and 120°. The bottom tension knob lets you customize how firm or easy the recline resistance feels — tailored to your preference and body weight.
• 360° Full Swivel Rotation: Rotate freely in any direction to reach different areas of your workspace without straining, making multitasking at a desk easier and more comfortable.
• High-Pressure Tested Iron Base: The black powder-coated 5-star iron base has passed rigorous high-pressure testing, ensuring the foundation remains stable, strong, and creak-free under sustained daily use.
• Anti-Slip Floor Protectors: Plastic footpads on every leg prevent the chair from sliding and protect hard floors and carpets from scratches and scuff marks.
• 5 Color Options: Available in Grey, Pink, Beige, White, and Blue — a range of tones that complement both neutral and accent-forward interior palettes.
