Description

Rocking chair and base framework thereof

Technical Field

The utility model relates to a seat field especially relates to a rocking chair and base skeleton thereof.

Background

The rocking chair is a leisure chair which has a rocking structure and can realize small-amplitude rocking by utilizing the force applied to the chair by a user. When a user sits on the rocking chair, the rocking chair can swing back and forth, and the purposes of relieving pressure and relaxing the body and mind are achieved. In the current rocking chair type, a direct floor type rocking chair is provided, namely a rocking base of the rocking chair is a chair seat part. According to the technical scheme disclosed by the Chinese utility model patents with the publication numbers of CN206102123U, CN203633799U and CN203633798U, the rocking chair frameworks built in the rocking chair are all spliced by adopting a wood structure, and particularly, the joint of the chair seat and the chair back is formed by adopting a wood panel to form good support.
