Due to the adoption of the double-layer spring structure, stronger supporting force can be provided compared with the traditional single-layer spring. This means that deformation or damage does not easily occur even under a large pressure, so that stability and durability of the sofa can be ensured.

The plurality of first springs 10 are sequentially distributed side by side at intervals along the first direction; at least part of the second springs 20 are sequentially distributed at intervals in a first direction, at least part of the second springs 20 are sequentially distributed at intervals in a second direction, and the first direction and the second direction are mutually perpendicular; alternatively, the plurality of second springs 20 are crisscrossed and crisscrossed.

The double-layer design of the first spring 10 and the second spring 20, and the third spring 30 connecting the first spring 10 and the second spring 20, can increase the elasticity of the seat, so that the seat can be restored to its original shape more quickly after bearing pressure.

The first spring 10 and the second spring 20 are serpentine springs, which are one type of spring commonly used in furniture and seating. The serpentine spring is continuously bent into an S shape by one steel wire, the serpentine spring is named as a serpentine body similar to a snake in shape, and the characteristic structure of the serpentine spring enables the serpentine spring to bear pressure better and not easy to deform, so that the serpentine spring has high durability. Such a spring design can provide better resilience and cushioning effects, thereby increasing the service life of the sofa.

The spring arrangement mode can provide more uniform and comprehensive supporting force, so that the weight of a human body sitting on the seat is uniformly dispersed, and the comfort of a user is improved.

The third spring 30 is a concave spiral spring, the outer radial middle part of the upper end part of the third spring 30 is gradually reduced, and the outer radial middle part of the lower end part of the third spring 30 is gradually reduced.

The design of the concave spiral spring can provide a larger elastic range, and when the concave spiral spring is stressed, the concave spiral spring can be gradually compressed to provide a better elastic effect. Because the outer radial middle parts of the upper end part and the lower end part of the spring are gradually reduced, the design can better disperse pressure, avoid pressure concentration, and can enhance the deformation resistance of the spring, so that the spring is not easy to deform under long-term use, and the durability of the seat is improved.

By arranging 2 third springs 30 between the first springs 10 and the second springs 20, more elasticity can be provided, so that the seat can better adapt to the weight and sitting posture of the user, and the comfort of the seat is improved.

A seat having a frame with a double layer spring structure connected thereto. The design of double-deck spring structure can disperse pressure better, reduces the pressure to single spring for the seat has bigger bearing capacity, can adapt to the user of different weight, thereby extension spring and seat's life.
