Description

Technical Field

[0001] The utility model relates to the field of sofa manufacturing, in particular to a drawer-type sofa. Background Art

[0002] A sofa is a multi-seat chair with soft cushions. The sofa seat is equipped with springs or thick foam plastics, the backrest is equipped with multiple cushions, and there are armrests on both sides. It is a kind of soft furniture. People are always used to chatting, leisure, entertainment or relieving fatigue on the sofa. With the gradual improvement of living standards, more and more functions are added to the actual manufacturing of sofas. For example, in order to increase comfort, a massage function is added, which can relieve fatigue well; in order to increase storage space, a drawer is added to the bottom of the sofa seat; there are also sofas that add cushions to form a sofa bed, which brings greater convenience for rest. However, when adding cushions to existing sofas to form a sofa bed, the cushions are usually folded on the sofa seat, which increases the thickness of the sofa seat. The softness of the sofa required for the sitting posture and the sleeping posture of the human body is not the same. After the sofa is folded, the human body is actually still sitting on the bed, which is very uncomfortable. There is also a method of adding a drawer to the bottom of the sofa seat and placing the cushion in the drawer. After taking out the cushion, the support feet at the bottom of the cushion need to be opened for support to be parallel to the height of the sofa seat. Although this can ensure comfort, the stability of this structure is relatively poor, and the support feet are easily damaged. It can only be replaced as a whole, which greatly wastes costs.
