[0002] In the prior art, with the improvement of material standards, people have higher and higher requirements for the user experience of sitting furniture. At present, the reclining chair is a seat used to relax the body in life. When the user sits on the reclining chair, he can adjust his center of gravity to achieve the function of swinging back and forth to relax the user's body.

[0003] In the prior art, in order to achieve forward and backward swinging, the rocking chair includes a base, a chair back provided on the base, and curved chair legs provided under the seat. Through the contact between the curved surface and the reference surface, the user can adjust his or her own center of gravity to achieve the function of rocking back and forth. The main disadvantages of this structure are: first, it occupies a large area and has low space utilization; second, it has a relatively single function and can only be used to relax the body. The rocking mechanism cannot be locked. When the user sits on the rocking chair, the body leans too far back and is not suitable for office use. The applicability is poor and cannot meet the user's office needs. Therefore, there is an urgent need for a multifunctional chair that can lock the rocking mechanism and is suitable for office use. During the user's office work, the user can lean forward and keep the waist upright, which can meet the user's needs of relaxing the body and meeting the user's office needs. Utility Model Content
