[0002] Common sofas include chair-type sofas with armrests, backrests and bases, and semi-reclining sofas with only backrests and bases. Semi-reclining sofas are mainly for users to lie down, but since the length of the base and the height of the backrest cannot be changed, the degree of fit varies for users of different heights, resulting in different levels of comfort, and the comfort requirements of users with a low degree of fit cannot be guaranteed. Utility Model Content

[0003] The main purpose of the utility model is to provide a sofa with an adjustable backrest, which has a simple structure and is easy to use and adopts a backrest to adjust the height and depth of the backrest.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0005] A sofa with adjustable backrest, comprising a backrest, a base and a movable backrest; one end of the base is connected to the middle of the backrest, and the other end of the base extends outward and is provided with a supporting leg extending downward; the movable backrest comprises a strip backrest and a 7-shaped backrest whose length matches the width of the backrest; the strip backrest is arranged at the connection between the base and the backrest, the bottom end of the 7-shaped backrest is arranged on the upper part of the strip backrest, and the top end is arranged on the top of the backrest; or, the bottom end of the 7-shaped backrest is arranged on the base, and the top end is arranged on the upper part of the strip backrest.

[0006] This solution adopts a movable back cushion, which includes a strip back cushion and a 7-shaped back cushion. A user of a semi-reclining sofa sits on the base with his back close to the movable back cushion at the backrest. For a taller user, the bottom end of the 7-shaped back cushion can be arranged on the upper part of the strip back cushion and the top end can be arranged on the top of the backrest, which increases the height of the backrest and leaves enough space on the base for lying down, so that the user can feel comfortable. For a shorter user, the bottom end of the 7-shaped back cushion can be arranged on the base and the top end can be arranged on the upper part of the back cushion, which reduces the height of the backrest and shortens the length of the base, so that the user can also feel comfortable.

[0007] As a preferred solution of the utility model, the outer side of the 7-shaped backrest is covered with a detachable leather cover.

[0008] As a preferred solution of the utility model, the backrest and the base are provided with a frame, and the outer side of the frame is covered with a sponge layer. The frame of this solution can be an iron frame, or a wooden or plastic frame.

[0009] As a preferred solution of the utility model, a bottom pad is provided on the upper side of the base, one side of the bottom pad is connected to the backrest, and the other side of the bottom pad is flush with the outer side of the base. The base of this solution is provided with a bottom pad, and the bottom pad is a movable part, which is convenient for users to use together.

[0010] As a preferred solution of the utility model, the base is in a 7-shaped structure, and a gap is provided between the supporting feet of the base and the backrest. The base of this solution is relatively long and the overall structure is relatively heavy. The provision of a gap can reduce the weight of the entire product and facilitate the reasonable use of space.

[0011] As a preferred solution of the utility model, the base pad is a sponge pad, and the outer side of the base pad is covered with a detachable leather cover.

[0012] The components of the present invention may adopt an internal frame and an external soft bag structure, or may adopt a whole piece of sponge pad, latex pad, etc. with a certain strength as the soft pad, and the outside may be covered with a detachable leather cover, cloth cover, etc.
