An ergonomic massage chair is configured with back and bottom structures held up by a pair of legs. The various support bars and structure of the ergonomic massage chair may be comprised of, in typical implementations, metal, but plastic and other suitable structures are also possible. The back structure has perimeter support bars that form the base of the back support, and horizontal support bars extend from a left perimeter support bar to a right perimeter support bar. The bottom structure likewise has a perimeter support bar that forms the structure of the bottom. A horizontal support bar extends from a left perimeter support bar to a right perimeter support bar. Nodes are attached to the ergonomic chair, and stability balls fit inside openings created by the support bars and nodes. A cover having memory foam pillows therein encapsulates the chair to provide users with customized setups that suit them.

An adjustable chair frame with a back and seating surfaces that flex to conform to the shape, weight and movement of an occupant is disclosed. The chair form and proportions provide for a recumbent position that disperses the weight of the occupant more evenly, thereby reducing external and internal physiological point loading. The form also provides ergonomic articulation to minimize internal physiological stresses such as neck/back vertebral compression. Eccentric connections driven by a motor assembly allow positioning adjustment of the components of the chair. Additionally, an air pump assembly may be included to automatically adjust one or more air bladders provided on the interior of the chair frame.

The present invention relates to support apparatus for supporting at least a portion of a gluteal region of a user while the user is seated in a seating apparatus comprising a seating surface, a back support surface and a transition region at the intersection of the seating surface and the back support surface. The support apparatus a support member structured to support at least a portion of the gluteal region of the user. The support apparatus further comprises a support element structured to position the support member at the transition region of seating apparatus such that the support member extends between the seating surface and the back support surface of the seating apparatus.

A chair support shell has an integral back portion, seat portion, and joining portion between the back portion and the seat portion. At least a major portion of the support shell comprises a compliant structure, the compliant structure having a plurality of cells interconnected by a plurality of resilient members. The compliant structure provides compliance in the seat portion, compliance in the back portion, and compliance in the joining portion. The compliant structure enables recline of the back portion relative to the seat portion.

An adjustable chair that converts into a bed with a hole in the center of the chair's seating area and ⅔ down when converted into a bed. The purpose of the hole is so that no pressure is applied to the gluteal are when sitting down or when lying down. This is essential after an operation on the gluteal area. The chair is a folding frame with cloth arranged on the frame and is also composed of a tripod. It also has an armrest to allow more comfort to user.

A physical conditioning and therapeutic conditioning system that, when configured and incorporated into the construction of a chair, has a seat, a base configured to rest on a surface, and a seat-support mechanism which is configured to couple the seat to the base and enables the seat, when unlocked in one embodiment, to be pivoted in any direction while rocking in the seat and using one's own body weight for resistance. Ideally the seat-support mechanism permits universal motion in all directions above a vertical axis, including front to back inflection and side-to-side inflection of at least 40° , including 360° of rotation on a universal type joint. The universal type joint is a ball joint consisting of a bearing stud and socket enclosed in a case, with all parts made of steel. In one embodiment, the bearing stud is tapered and fits into a hydraulic post. A ball joint is used to allow free rotation in two planes at the same time.

The universal ball joint when attached to the underside of a seat is surrounded by a metal caste collar, also attached to the underside of the seat, and with a locking system attached to the upper collar. Inserted into the upper collar, along with a lower collar attached to the arm support structure, surrounding the ball joint assembly is a hardened metal coiled spring, used ideally to stabilize, through compression, the seat in a horizontal position and allow for locking the seat in a horizontal position, when no force is applied or when not in use.

A body support assembly includes a seat assembly and backrest assembly supported by a tilt control assembly. Methods of using and assembling the body support assembly are provided.

A body support structure includes a structural lattice structure having a first stiffness, and a compressive lattice structure supported by the structural lattice structure and having a second stiffness less than the first stiffness. A skin lattice structure is supported by the compressive lattice structure, wherein the skin lattice structure is resistant to shear deformation in response to a normal force and is expandable in a direction transverse to the normal force.

A chair that provides movement side-to-side about a first pivot axis positioned above the seat plane allows the user a wide range of dynamic movement, but does not require constant or excessive action on the part of the user to maintain a desired position. In addition and concurrently thereto, the structure may include a second pivot that is also positioned above the seat plane and that provides forward-and-back movement of the seat. The first and second pivot axes can be engaged synchronously or independently by the user as desired delivering infinite degrees of angles of movement. Said pivot axes are more closely adjacent to the human body pivot joints and axes. The seat and seat back may be joined together to a central spine frame that moves about the second pivot, thereby maintaining the seatback position and seat position relative to each other during forward-and-back movement of the spine along the second pivot. One or more biasing structures may be provided to urge the seat into forward-and-back and side-to-side neutral positions. If desired, the location of this forward-and-back neutral position can be statically adjusted by a user, and at least one of the biasing structures can hold this forward-and-back neutral position at a desired tension level thereby allowing a user to select the amount of force required to move the seat out of this defined forward-and-back neutral position. Moreover, an adjustment structure may be provided that allows for static adjustment of the seatback's position on the spine.
