Good seats that are comfortable to sit on and can be used for a long time, in addition to having the correct curve, the most important thing is to be comfortable to sit on. Therefore, the quality of the cushion must be paid attention to. Therefore, the one-piece PU cushion is an ideal cushion, which has the characteristics of good elasticity, no deformation, no aging, no combustion and non-toxicity. In addition, muscles are very important for supporting the human body and maintaining proper posture, but muscle tension and contraction are also the source of fatigue.

Therefore, good public seats must be able to give the body proper support to reduce its tension. The appropriateness of the cushion is the main reason for muscle fatigue. The cushion is too soft, the density is too low or uneven, it cannot stabilize the body, support the body evenly, and deform the sitting posture, resulting in muscle fatigue.

Good public seats must be able to meet dynamic requirements. There is no fixed posture that is an ideal sitting posture, and many actions must be performed on the seat during working hours. Although the synchronous reclining structure can meet some dynamic requirements, when the seat is at the correct seat height, the front edge of the seat will be raised excessively when the user leans back, and the soles of the user's feet cannot be flat on the ground, leaving only the toes barely touching the ground, which causes the body to be in an unstable state, causing muscle tension and even accidents.

At the same time, the front edge of the seat is embedded in the muscles at the bottom of the thigh, which also inhibits blood circulation. The human body is made up of joints, so it has very good elasticity and mobility. If the human body is compared to a "seat", it will also be the most ergonomic "waiting chair". The new reclining structure is designed based on the physiological structure of the human body. It replaces the traditional dull materials and styles with colorful and technologically innovative structures, which can make users feel comfortable sitting for a long time.
