Description

Technical Field

[0001] The utility model relates to the technical field of bathrooms, and in particular to a toilet seat. Background Art

[0002] The surface of existing toilet seats that come into contact with the human body is usually made of hard plastic materials such as urea-formaldehyde and PP. When these hard materials come into contact with the human body, there is an uneven pressure distribution on the surface of the seat. In addition, the curved surface of existing toilet seats cannot completely match the shape of human thighs and buttocks. When using the toilet, the human body posture is in dynamic change, and the hard surface cannot adapt to the changes in human pressure. When the human body sits on the toilet seat for a long time, it is easy to cause discomfort to the human body such as thigh paralysis and concentrated pressure on the buttocks, and the human-computer interaction is not friendly enough.
