[0023] Refer to Figures 1 - 5 As shown, the following technical solutions are adopted in this detailed implementation manner: It includes an integrated seat 1, an adjustable connection bracket 2, and a roller bracket 3; the upper end of the roller bracket 3 is connected to the integrated seat 1 through the adjustable connection bracket 2; among them, the integrated seat 1 is composed of a wrapped integrated frame 11, a high-density support sponge 12, a backrest soft sponge 15, a seat cushion soft sponge 16, an airbag-type lumbar support 17, an air pump 18, and an adjustment switch 19; a layer of high-density support sponge 12 is laid inside the wrapped integrated frame 11, and a backrest soft sponge 15 is arranged inside the reserved slot 13 in the middle of the backrest of the wrapped integrated frame 11, and a seat cushion soft sponge 16 is arranged inside the reserved slot 2 14 in the middle of the seat cushion of the wrapped integrated frame 11.

[0024] Among them, the inner and outer surfaces of the wrapped integrated frame 11 wrap and fix the high-density support sponge 12, the backrest soft sponge 15, the seat cushion soft sponge 16, and the airbag-type lumbar support 17 through breathable leather and stitches, and are closely attached to the wrapped integrated frame 11; the adjustment switch 19 is fixed inside the card slot at the rear end on the right side of the wrapped integrated frame 11 through bolts.

[0025] In addition, the wrap-around integrated frame 11 is formed by an integrated die-casting process, which integrates the backrest support, the seat cushion support, and the left and right wrap-around armrests into an integrated structure; at the upper end of the back of the integrated seat 1, there is a headrest fixing seat 4, the rear end of the headrest fixing seat 4 is connected with a hanger-type handle 5, and the upper end of the headrest fixing seat 4 is connected with a headrest 7 through an inserted adjustment bracket 6.

[0026] Advantages of this specific embodiment:

[0027] 1. Better ergonomic fit and precise support for different parts: The structure of the human back is complex, and different regions have different requirements for support. The lumbar region requires strong support to maintain the normal physiological curvature of the spine and reduce the pressure on the waist; near the scapula, relatively soft support is needed to provide a comfortable fit. Sponges with different densities can be precisely matched to the needs of these different parts; harder sponges are used for parts such as the waist that require strong support, which can effectively prevent the waist from sagging and fatigue; softer sponges are used for areas on both sides of the back that do not require excessive support, making the user feel more comfortable and natural when leaning, thus better conforming to the curve of the human back as a whole and providing personalized support.

[0028] 2. Adapt to various sitting postures: People often change their sitting postures during work, such as sitting upright, leaning forward, and leaning backward. This design can provide good support for the back in various sitting postures. When the body leans forward, the hard sponge in the waist can support the lumbar spine and keep the spine stable; when the body leans backward, the entire back can be correspondingly supported and fitted, so that the user can maintain a comfortable state no matter what posture they are in.

[0029] 3. More uniform pressure dispersion and reduction of local pressure points: If a single-density sponge is used for the back of an office chair, it is easy to form local pressure points at the contact parts with the human body, and sitting for a long time will cause physical discomfort; while the combination of sponges with different densities can make the contact between the back of the chair and the human body more uniform, distributing the body weight to different areas and avoiding excessive local pressure. This can reduce the fatigue and pain caused by long-term compression, improve the comfort of the chair, and even sitting on the chair for a long time will not feel overly tired.

[0030] 4. Relieve muscle fatigue: The uniform pressure distribution helps to relax the back muscles. The appropriate sponge density can provide a certain buffer for the back muscles while providing support, avoiding excessive muscle tension. This is very important for office workers who often need to sit for a long time, which can reduce the fatigue and stiffness of the back muscles and prevent problems such as muscle strain.

[0031] 5. Improve the durability of the seat and distribute the stress reasonably: Foams with different densities cooperate with each other in the integrally formed structure, enabling it to better bear the weight of the human body and various pressures. The hard foam part can undertake the main support task to ensure the structural stability of the seat. The soft foam part can play a role in buffering and dispersing the pressure, reducing the impact on the hard foam. This reasonable stress distribution can extend the service life of the seat and prevent problems such as deformation and collapse.

[0032] 6. Maintain shape stability: The integrally formed manufacturing process can tightly combine foams with different densities to form an integral structure. Such a structure has good shape stability. Even after long-term use and frequent leaning, the backrest of the seat can maintain its original shape and support performance, without affecting the use effect due to the deformation of the foam.

[0033] 7. Enhance the use experience, health, and comfort: Combining the above advantages, this design can provide users with a more comfortable sitting experience. A comfortable seat can make office workers more relaxed during work, reduce restlessness and anxiety caused by physical discomfort, and improve work efficiency and quality.

[0034] 8. Help maintain the correct sitting posture: Good back support and uniform pressure distribution can guide users to maintain the correct sitting posture and avoid the formation of bad postures such as hunching. The correct sitting posture helps maintain spinal health and reduces spinal diseases and other health problems caused by improper sitting postures.
