Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0046] As people's quality of life improves, they pay more attention to their bodies. Massage chairs use mechanical force to massage the human body to improve human discomfort.

[0047] At present, in order to allow users to sit in a more comfortable sitting posture on the massage chair, the back and legs of the massage chair can be adjusted in angle while the massage manipulator is massaging the human body. After the user sits on the massage chair, the angle of the backrest and legs can be adjusted, so that the user can lie down in a zero-gravity state or be massaged at a comfortable angle.

[0048] However, in order to adjust the angles of the back and legs, current massagers require two regulators to control them separately, resulting in high costs.

[0049] Based on the above problems, the present application discloses a massage chair, which uses an adjuster (also referred to as a driving member in this article) to simultaneously adjust the angles of the back and legs of the chair to reduce costs.

[0050] Combination Figures 1 to 9 As shown, the massage chair in the present application includes: a base frame assembly 2, a backrest assembly 1, a leg assembly 5, a linkage assembly 4 and a driving member 3.
