An angle adjustment assembly includes a first connecting piece including first side plates, a second connecting piece including second side plate, and a limiting rod. The first side plates are hinged to the second side plates. The first side plates include a through hole that is arc-shaped and centered at a hinge joint of the first side plates and the second side plates. A path of the through hole has at least one expansion groove. The limiting rod is axially movably connected with a corresponding second side plate. The limiting rod includes a first sections and a second section. A diameter of the first section is smaller than a diameter of the second section. A size of the first section matches a size of the through hole. A size of the second section matches a size of the at least one expansion groove.

The invention relates to a chair for accommodating a person. The chair includes an upper body section having an upper body contact surface adapted or adaptable to at least parts of a front of a torso or a rear of a torso of a person placed on the chair, and a lower body section having a lower body contact surface adapted or adaptable to at least parts of at least a front of a thigh of the person, wherein the upper body section and the lower body section are arranged or arrangeable and fixable in a position relative to each other such that the upper body contact surface and the lower body contact surface cause a hyperextension posture of the hip joint of the person with a predetermined hyperextension angle. By forming the hyperextension angle of the hip on the chair, shortening of the anterior thigh and hip muscles can be counteracted. Also disclosed are a pressing device for application to the human body, which is adapted for use on a chair and which includes one or more pressure units each having at least one pressure head adapted to apply local or point pressure at a predetermined pressure location on the body of a person accommodated on the chair, and a chair having such a pressing device.

A multifunctional chair is disclosed, including: a first frame body unit, the first frame body unit including a head end and a tail end; a first supporting unit configured to support the first frame body unit, the first supporting unit connected with a first connecting position of the first frame body unit and a height of the tail end of the first frame body unit being lower than a height of the first connecting position; a first leaning unit arranged in a position of the first frame body unit close to the first connecting position; a second frame body unit arranged on a back portion of the first frame body unit, the second frame body unit and the first frame body unit being rotatably connected, the second frame body unit and the first frame body unit in rotatable connection being capable of moving between a first posture of a reclining chair or a seat and a second posture of fitness equipment, the second frame body unit and the first frame body unit being in the first posture when having an angle, and the second frame body unit and the first frame body unit being in the second posture when the tail ends of the second frame body unit and the first frame body unit are overlapped; and a second leaning unit arranged on the second frame body unit. The multifunctional chair has multiple functions and is also used for seats, recliners and fitness equipment, and has simple structure, simple and fast operation, convenient use, and easy to carry and transport.
