Description

Sofa structure

Technical Field

The invention relates to the technical field of sofas, in particular to a sofa structure.

Background

The sofa is a chair with a cushion, belongs to furniture, and is widely applied to modern life because people feel comfortable when using sofa in life.

The sofa comprises a seat frame, a seat cushion, armrests and a backrest, wherein the seat cushion is placed on the upper surface of the seat frame, the backrest and the seat plate are arranged in an L shape, the backrest is fixed on one side of the upper surface of the seat cushion, and a user can conveniently rest on the seat cushion and lean against the backrest. The seat cushion of the existing sofa is usually a cotton cushion, when a user sits on the upper seat cushion, the seat cushion is sunken downwards, and then the contact area of the seat cushion and a human body is larger, so that the user sitting on the seat cushion feels softer and more comfortable.

However, in such a structure, when a human body comes into contact with the seat cushion, the seat cushion deforms, and the larger the deformation amount of the seat cushion, the larger the reaction to the human body, the larger the difference in the pressing force received by different parts of the human body, and further, the local position of the human body is subjected to excessive force, which causes discomfort.

Disclosure of Invention
