Anshan Office Chair Introduction

Anshan office chairs are important pieces of furniture that directly support the human body in office environments. Their design emphasizes comfort, ergonomic adaptability, and safety, with some models such as DP16, DP15, and SA25 being renowned for their support and anti-fatigue performance.

Types and Core Features

Anshan office chairs come in multiple models (e.g., DP16, DP15, SA25), with their core advantage being comfortable support through ergonomic design. For example, the seat depth, width, height, and back curvature are all designed based on human body measurements to ensure that the user's thighs are supported and the lumbar spine is properly cradled when seated, reducing fatigue from prolonged sitting. The armrest height and width of some models are reasonably designed to allow the arms to rest naturally, further relieving shoulder and neck stress.

Key Points of Ergonomic Design

1. Adjustable Functions:

   • Seat Height Adjustment: Ensure that both feet are flat on the ground, with the angle between the thighs and lower legs being 90°-105°, to avoid pressure on the front edge of the seat from the thighs.
   • Lumbar Support: The backrest should fit the third and fourth lumbar vertebrae, providing multi-dimensional adjustment (up, down, forward, and backward) to maintain the natural curvature of the lumbar spine and reduce the burden on the lumbar muscles.
   • Backrest Recline and Tension: The backrest can recline and lock at different angles, with adjustable recline resistance (tension) to accommodate users of different weights.
   • Armrest Adjustment: The armrest height should be adjustable, with some models supporting front-back and left-right angle adjustments to coordinate with elbow movements and keep the shoulders relaxed.
   • Seat Cushion and Material: The front edge of the seat cushion adopts a 'waterfall' design to reduce pressure on the back of the thighs. In terms of materials, mesh offers good breathability but is relatively firm in support, while foam is soft but has slightly inferior breathability, so the choice depends on individual needs.

2. Safety and Durability:

   • Structural Stability: The metal frame must withstand impacts and long-term loads far exceeding normal body weight.
   • Fire Resistance: The fabric, foam, and plastic components must comply with fire safety standards to delay the spread of fire.
   • Edge Treatment: All edges should be rounded to avoid accidental injuries caused by sharp parts.
   • Material Durability: The fabric should be tear-resistant, abrasion-resistant, and stain-resistant; metal parts should be rust-proof and corrosion-resistant; and the mechanism should undergo tens of thousands of opening and closing tests to ensure long-term smooth operation.
