Gree Office Chair
Gree's office chairs, represented by the K7 ergonomic chair, feature ergonomic design, durable materials, and a safe structure, making them suitable for multiple scenarios.

Lumbar Support System: Precise Support for Diverse Body Types
The K7 ergonomic chair employs a 'four-dimensional lumbar support' system that allows for adjustments in four directions: forward, backward, up, down, left, right, and rotation, with a precision of 1mm. This design precisely matches the lumbar curves of users with different body types, particularly suitable for those who are overweight or have sensitive lumbar regions. Its support force is 40% greater than that of ordinary lumbar supports, effectively dispersing lumbar pressure and reducing fatigue from prolonged sitting.
Seat Cushion Material: Balancing Durability and Comfort
The seat cushion is made of thickened molded foam with a density of 60kg/mยณ, offering a balance between a moderately soft and firm sitting experience and durability. After testing, it shows only a 3mm indentation after 1000 hours of continuous use, maintaining its shape well over long-term use, making it ideal for users who need to work for extended periods.
Technical Structure: Safe, Stable, and Family-Friendly
The chair is equipped with a thickened steel five-star base (70cm in diameter) and an explosion-proof chassis, ensuring no wobbling under a pressure of 150kg, demonstrating strong structural stability. It is suitable for families with children or pets. The multi-directional adjustable armrests support adjustments in four dimensions: up, down, forward, backward, left, right, and rotation, adapting to various scenarios such as desks and sofas, enhancing usage flexibility.
Operating Entity and Service Scope
The operating entity of Gree office furniture is located in Shuiteng Longwei Furniture Material City, Foshan City, Guangdong Province, primarily providing office chair processing and material services. This location facilitates the integration of supply chain resources, ensuring product quality and production efficiency, while also providing convenient after-sales support for regional users.
Summary: The Gree K7 ergonomic chair meets the needs of different users for comfort, support, and scenario adaptability through its ergonomic design, highly durable materials, and safe structure, making it especially suitable for those who work for long hours or have high requirements for lumbar health.
