Butterfly-style Office Chair

Represented by the Gaotian GTChair Butterfly Ultra, the butterfly-style office chair is an ergonomic seat specifically designed for people who sit for long periods, combining comfort, functionality, and adaptability.

I. Core Ergonomic Structure and Adjustable Functions

1. Dynamic Support System: Utilizing the A’PAS intelligent sitting posture adaptation system and the Flex Island adaptive lumbar support, the lumbar support automatically conforms to the lumbar curve as the body posture changes, filling the gap between the waist and the backrest, effectively reducing waist soreness and tension caused by prolonged sitting.
2. Material and Breathability: The backrest and seat cushion are made of Wintex high-elastic mesh fabric, which combines toughness and support, is resistant to collapse, and offers excellent breathability. It is suitable for all seasons, keeping you cool in summer and preventing discomfort from overly cold materials in winter.
3. Multi-dimensional Adjustment Design:
   • 5D Wired Control Paddle Armrests: The adjustment controls are integrated at the front of the armrests, supporting multi-dimensional adjustments including up and down, forward and backward, left and right, and rotation, accommodating different arm placement habits and reducing shoulder and neck strain.
   • Synchronized Gliding Mechanism: When the backrest reclines, the seat cushion synchronously slides forward, maintaining a stable center of gravity with a maximum recline angle of 160°, suitable for short naps.
   • Headrest and Seat Depth Adjustment: The 4D large headrest supports multi-directional angle and height adjustments, conforming to the neck curve; the seat depth can be adjusted forward and backward to accommodate users with different leg lengths, optimizing leg support.

II. Functional Advantages

1. Neck and Waist Protection: The 4D curved headrest and adaptive lumbar support provide dual support, with the headrest conforming to the neck in multiple dimensions to reduce cervical spine pressure; the lumbar support dynamically follows body posture to prevent slouching during prolonged sitting and reduce waist fatigue.
2. Mode Switching: Supports a large recline angle of 160° with multi-position locking, allowing you to maintain an upright sitting posture for studying or working and switch to a rest mode with one-touch recline for short naps, enabling free switching between focus and rest modes.
3. Long-term Durability: The mesh fabric is highly resistant to collapse, maintaining good support performance even after long-term use; the seat height adjustment uses a Korean Sanhong four-stage gas spring, ensuring high stability and safety.
