Description

Technical Field

[0001] This utility model relates to the field of sofa technology, specifically to a sofa seat frame structure that facilitates reduction in packaging size. Background Technology

[0002] Traditional sofa designs often limit the separation of sofa cushions and sofa frames, while the sofa frame structure is often integrated. This results in the sofa frame taking up a lot of space during storage and transportation, leading to reduced transportation volume and increased transportation costs. This is especially true for export sofas, as there are strict cost levels for the loading dimensions of export containers. Minimizing the volume occupied by the sofa itself is one way to reduce transportation costs.

[0003] Therefore, in order to solve the above problems, there is an urgent need in the market for an innovatively designed sofa frame that can be disassembled or folded according to storage and transportation needs, and whose structural design ensures stability and durability, while pursuing comfort and environmental protection in material selection, so as to improve the user experience and quality of life.
