Qin Qin Office Chair

The brand 'Qin Qin Tian Yuan' includes office chair products, designed with clear ergonomic principles and available at various prices in the market.

Dimensional Design Basis

The dimensional design of office chairs closely adheres to ergonomic principles to accommodate the physical characteristics of different individuals. The seat height is designed based on the 50th percentile of leg length, with the 50th percentile for adult Chinese males being approximately 970 millimeters. This design ensures that users can sit with their feet naturally on the ground and their thighs and calves at a comfortable angle, reducing leg pressure. The seat width is designed according to the 85th percentile of hip circumference, with the 85th percentile for adult Chinese males being approximately 1020 millimeters, ensuring sufficient support space for the hips and preventing discomfort caused by a narrow seat.

The armrest height is referenced from the 50th percentile of shoulder width, with the 50th percentile for adult Chinese males being approximately 470 millimeters. An appropriate armrest height allows users to place their arms naturally, reducing shoulder and arm fatigue. The backrest height is designed based on the 50th percentile of trunk forward lean angle, with the 50th percentile for adults being approximately 5 degrees, providing good lumbar support and maintaining the natural curve of the spine. The backrest width is designed according to the 50th percentile of the distance between the back's concave point and the shoulders, with this distance being approximately 380 millimeters, ensuring comprehensive and comfortable back support.

Market Price Situation
