The present disclosure provides a back body support 1000 that is provided with the related assemblies, such as a primary elongated cushion member 100, a secondary elongated cushion member 200, a headrest extension member 300, a flexible seating support member 400, a tail bone and buttocks support member 500, a rigid seat member 600, and a posture correction member 700, which may be coupled to one another to provide one or more combinations to be used by a user in one or more ways, such as while sitting or while walking, to provide support to back portion thereof, particularly, along the spine, and pelvis and buttock portion of a body of the user.

A pillow cover has a pillow case having a pocket, a pocket opening, a cavity, and an opening, the opening configured to allow the pillow case to receive a standard-sized pillow into the cavity, a support pillow insert insertable into the pocket through the pocket opening to form a support pillow on the surface the pillow case, and an attachment to allow the pillow cover to be adjustably attached to a chair.

The adjustable headrest mechanism for a chair comprises a pair of sliding rails; an upper driving rod and a lower driving rod, the upper driving rod being attached to the sliding rails and the lower driving rod being attached to a back frame of the chair; and a headrest actuator pivotally connected between the upper driving rod and the lower driving rod for operably driving the upper driving rod to move between a first position and a second position, thereby driving the sliding rails to pivotally move in an upward direction or a downward direction relative to the lower driving rod. When the upper driving rod is in the first position, the sliding rails is in a complete close state. When the upper driving rod is in the second position, the sliding rails is in a complete open state.

A foldable massage chair, including a face pillow assembly for supporting the head, a chest pillow assembly for supporting the chest, a handrail assembly for supporting wrists, a front support piece, a seat cushion assembly, a back support rod, a kneeboard assembly, a back supporting frame, and a front supporting frame. When a user needs to use this chair, it is placed in an expanded or use position, so the user may sit on the seat cushion and lean on the massage chair, completely exposing his back, waist, and hips for a masseur to massage. When the chair needs to be put away, it is possible to fold down the chair into a collapsed position by folding the seat cushion assembly, front support piece, chest pillow assembly, and handrail assembly. Also, the front supporting frame is folded towards the back supporting frame. Consequently, the size of the entire chair decreases.

The invention provides a travel pillow that is adapted to rest the head of a user upon the chest. The inventive travel pillow comprises a pillow member that is adapted to be positioned beneath the chin of the user. The pillow member is coupled to securing members that use the weight of the user in a seated position to maintain the pillow member in a desired position beneath the chin of the user.
