Significant beneficial effects are mainly reflected in the following aspects:

[0016] 1.Precise monitoring and instant feedback: the piezoelectric film sensors are selected as the sensors due to compactness in thickness and size and can be precisely placed in different areas of the chair back, such that a pressure and position of a user’s back leaning against the chair back can be comprehensively monitored. Once any poor sitting posture is detected, e.g., when the user’s back is not in full contact with the chair back or the pressure of leaning against the chair back is uneven, the sitting posture monitoring and warning module is capable of immediately emitting a prompt sound to remind the user to adjust the posture in a timely manner, thereby effectively avoiding subjectivity and hysteresis of conventional sitting posture correction methods.

[0017] 2. Comfort and protection: a double-layer structure design of the cloth cover and arrangement of the second hollow part corresponding to the first hollow part of the chair back ensure effective installation and operation of the sensors and prevent direct contact between a user’s spine and the chair back, thereby reducing spinal pressure, offering a more comfortable sitting experience, and protecting the user’s spine.

[0018] 3.Intelligence and convenience: the sitting posture monitoring and warning module integrates the components such as the power supply, the circuit board and the speaker, and is capable of easily activating and deactivating the entire system through the simple contact switch. A design of the charging interface enables repeated recharging of the power supply, and extends a service life of the chair. Further, use of wire harnesses achieves power supply and communication and ensures stable signal transmission.

[0019] 4.
