Office Chair Disassembly Explanation

The disassembly of the Livorno S02 executive chair can be analyzed from two aspects: functional structure and materials.

I. Functional Structure Disassembly

1. Electric Adjustment System
   The chair is equipped with four independent motors, enabling precise adjustments in multiple areas: the headrest supports 0-60° electric adjustment to accommodate different sitting postures; the backrest has an adjustment range of 95-160°, suitable for both upright office work and semi-reclined rest; the leg rest can be lifted upward with a single button operation, while the seat cushion moves forward and upward simultaneously, creating a zero-gravity lying position that distributes body pressure. Additionally, the seat has an 8-centimeter electric adjustment function in the front and back to cater to the leg support needs of users of different heights.

2. Massage and Heating Module
   The massage function is provided by 2 sets of a total of 5 airbags covering the entire back area, offering 3 levels of intensity adjustment. Its massage strength is superior to that of ordinary car seats, making it suitable for relaxing muscles after long hours of office work. The heating module is located directly opposite the waist area, achieving local warming by blowing air upward through small holes, which can relieve waist fatigue in winter.

3. Support and Space Design
   The seat width reaches 90 centimeters, and the backrest and seat cushion have thick fillings, providing a wide supporting surface. Its design is inspired by business vehicle aviation seats, emphasizing ergonomic support, especially suitable for users who need to maintain a sitting posture for long periods.

II. Material and Craftsmanship Disassembly

1. Surface Material
   The contact surface is made of European imported top-grain leather, which is breathable and wear-resistant with a soft touch; non-contact areas (such as the sides and back) use PVC artificial leather, reducing costs while ensuring durability.

2. Internal Structure
   The fillings may use high-density foam or memory foam to balance support and comfort; the frame part may use metal or engineering plastics to ensure structural stability. The electric adjustment components (such as motors and slide rails) need to pass durability tests to support frequent use.

III. Extension: The Feasibility of Refitting Used Car Seats into Office Chairs
If cost or DIY needs are considered, the middle-row seats of the Buick GL8 have become popular refitting objects due to their size and comfort. The fabric version costs about 300 yuan, and the leather version costs about 500 yuan. Additional accessories such as bases and casters need to be purchased. When refitting, note the following:

• The width and height of the seat should match the office desk;
• An electric adjustment module needs to be installed (if the original car does not have electric functions);
• Safety should comply with office furniture standards (such as load-bearing capacity and stability).
