[0002] Chairs are a common piece of seating, essential furniture in homes, offices, schools, and public spaces. They support the body, allowing people to maintain a comfortable posture while sitting and reducing stress and fatigue. A chair primarily consists of a base, seat, backrest, and armrests. The backrest's primary function is to support the back, ensuring a comfortable sitting posture. It provides support, comfort, and spinal protection.

[0003] To improve comfort, existing chair backs are typically constructed by wrapping the back panel with padding, then covering the padding with fabric, and finally securing the fabric, padding, and back panel with rivets or nails. Padding is typically made of sponge or other materials for comfort, while fabric is typically made of leather, suede, fabric, or mesh.

[0004] The chair back has the following deficiencies: (1) The fabric around the chair back is easily damaged. Take the gaming chairs placed in Internet cafes or the seats placed in stations, airports, and cinemas as examples. In public places, there is a large flow of people. In a crowded and relatively small space, the outer edge of the chair back is often bumped by people or luggage, and the fabric wrapped around the outer edge of the chair back will be worn or broken, and it is also easy to be burned by fire sources such as cigarette butts. (2) Because the chair backs are not flat, they all have a certain curvature, and side panels are provided on both sides for support purposes to adapt to the shape of the human back and make it more comfortable to use. Therefore, when installing fillers and fabrics, the chair backs of the existing structure are difficult to install, not easy to fix, and the flatness and fit are also relatively poor.
