[0002] At present, sofas are furniture for daily use. They can provide a soft and elastic surface for people to sit and lie on through the shock-absorbing components installed inside. Traditional sofas mostly adopt a prefabricated structure. This type of sofa occupies a large space, which is inconvenient to transport. It is also easy to bump into it during transportation, and it may even be difficult to move into the house due to the small size. In addition, the prefabricated sofa has a large volume, and the volume of packaging required during transportation is large, and the transportation cost is relatively high, which leads to increased costs.

[0003] Publication No. CN207055248U discloses a rotatable sofa, including a sofa body and a chassis arranged at the bottom of the sofa body, the sofa body including a left armrest, a right armrest, a backrest, a cushion and a base, and also including a rotating mechanism arranged between the chassis and the base, the rotating mechanism including a motor, a rotating shaft connected between the chassis and the base and electrically connected to the motor, an outer disc arranged on the chassis, an inner disc arranged at the lower end of the base and matching the outer disc, and the outer disc and the inner disc are both sleeved on the rotating shaft. This design structure can drive the sofa to automatically rotate to the angle required by the user, which is convenient for the user to use. The rotating structure of this rotatable sofa is complex and is still connected to electricity, resulting in high cost and poor controllability, which easily leads to poor user experience.

[0004] For this purpose, we propose a rotating sofa. Utility Model Content
