1. Seat and Back Sponge: Manufactured from high-quality polyurethane raw materials using one-time foaming molds to achieve high density, excellent rebound resilience, and lasting shape retention without deformation.

2. Fabric: Premium seat-specific wear-resistant fabric selected for optimal softness and firmness, providing a comfortable hand feel. Multiple color options are available to match various interiors.

3. Seat and Back Outer Panels: Constructed from high-quality veneer hot-pressed into multi-layer panels with an elegant wood veneer back. The thickness is at least 15mm. After multiple polishing stages and application of environmentally friendly paint, the panels achieve vibrant color, clear wood grain, and are odor-free. Wood panel color can be customized.

4. Return Function: The seat bag automatically returns to its original position when not in use. It employs a damping and spring return structure that is fault-tolerant and durable. The seat frame's main body is a steel frame (welded from 1.5mm thick steel plate) combined with five S-shaped snake springs (3.6mm diameter) for comfort and longevity. This eliminates the outdated plywood or iron frame cover structure still common in the market.

5. Armrest Surface: Made from high-quality oak that undergoes dehydration, degreasing, and precision processing. The surface is finished with environmentally friendly polyester paint, resulting in a smooth, delicate texture.

6. Footstand: The armrest frame is fabricated from premium 2.0mm steel plate, stamped and welded using custom molds. After phosphating and acid washing, the surface receives a frosted gray spray coating, delivering a modern, aesthetically pleasing appearance.

7. Writing Board: The substrate is made of medium-density fiberboard (MDF) with a melamine board surface and PVC edge banding on all sides, ensuring durability and longevity. The supporting bracket uses solid round iron with a diameter of ≥14mm and a load capacity of ≥40kg. The writing board folds and hides inside the armrest frame when not in use, saving space.

8. Side Panel: Produced from medium-density fiberboard sprayed with environmentally friendly adhesive and covered with flame-retardant hemp wool fabric. The fabric material matches the seat and back cotton for consistency. Movable buckle nails enable easy disassembly and assembly.
