Technical Field

[0001] The utility model relates to the technical field of sofas, in particular to a sofa with an adjustment structure. Background Art

[0002] A single sofa is a piece of furniture suitable for one person, usually with a comfortable seat and backrest design. It is a common seat in home decoration, which not only meets the needs of personal rest and relaxation, but also adds style and comfort to the interior space. The size of a single sofa is relatively small, suitable for placing in a smaller space or as an additional seat. It can be placed in different places such as the living room, bedroom, study or office, providing people with an independent and private rest area.

[0003] Current single sofas are usually equipped with the function of adjusting the cushion angle. However, although the cushion can be adjusted in angle, the seat cushion often cannot follow the adjustment of the cushion to adapt to the user's sitting or lying posture. As a result, after adjusting the cushion angle, the user will feel that the seat cushion angle still does not fully meet his or her personal needs or comfort. In view of this, we propose a sofa with an adjustment structure. Utility Model Content
