Electric Sofa Office Chair

An electric sofa office chair is a type of seating that combines electric adjustment functions with ergonomic design, offering a variety of features and types with a wide price range.

I. Functional Features
The core function of an electric sofa office chair is to switch between sitting and lying positions through an electric push rod. Its working principle involves the drive motor converting rotational motion into linear motion of the screw via reduction gears, with the guide sleeve assisting in stabilizing the travel, ultimately driving the backrest to rise and fall and the seat cushion to move in tandem. This process is quiet, has strong thrust, and features strong self-locking force to ensure safety during use. High-end models are also equipped with lumbar support devices for the back, armrest lifting systems, and four/five electric modules, allowing precise adjustment of lumbar support and arm height. Some integrate massagers and temperature control components, supporting heating and ventilation functions, and even enabling smart control through the Mi Home APP.

II. Structure and Materials

1. Structural Types: In the home furnishing sector, parallel structures are commonly used to ensure stability of the center of gravity during adjustment.
2. Fabric Types: There are two main categories: fabric and leather. Fabric models offer good breathability and are suitable for prolonged use; leather models (such as those made of genuine leather) have a high-end feel, are easy to clean, but require regular maintenance.
3. Core Components: These include the drive motor, reduction gears, screw, guide sleeve, etc. Some high-end models use silent motors and high-strength screws to extend service life.
