The present design is of a variable posture component system seating device, also called a work chair, which integrates user selectable and adjustable components. The components consist generally of a short base, a long base, height adjustment mechanisms, a seat adjustment mechanism, a seat assembly, right and left arm rest assemblies, an abdominal rest assembly, a back rest assembly, a head rest assembly, a knee/leg rest assembly, a keyboard desk assembly, an auxiliary desk assembly, a horizontal work surface assembly, and a variety of interconnecting hardware. Numerous improvements to a variable posture work chair are incorporated into the design, which can benefit workers subjected to extended periods of immobilization as well as the infirm and the injured. Fore and aft support from a single seated position is provided over the entire range of leaning normally associated with human sitting. A variety of work surfaces may be incorporated into the design, and certain of these may be mounted to the chair by using arm rests which may also be moved between positions of use and nonuse. Components may be added, removed, or displaced to accommodate specific physical and workplace needs. An elongated low profile chair base of single unit construction provides stability to the chair assembly while allowing for maximum leg and foot clearance. Suggested uses are in the home, office, and industrial work place.

A multi-task configurable, continuously variable posture seating device, the seating device comprising: a base comprising: a cross member; a main member that is longer than the cross member the cross member being rigidly attached to the main member in a position such that the main member substantially bisects the cross member and forms a cross having three arms of substantially the same length and a fourth arm that is longer than the rest of the arms, the fourth arm further comprising a section of reduced elevation, so that at least part of the portion of the fourth arm that extends beyond the three arms of substantially the same length will have an overall height that is lower than the height of the three arms of substantially the same length; and a short member that is shorter than said cross member and is attached to the fourth arm at a position that permits the fourth arm to substantially bisect the short member; a height adjustable support means mounted on said base; a seat portion; at least one armrest, the armrest having means for accepting a task accessory; means for pivotally attaching said armrest to said seat portion, said means for pivotally attaching said armrest comprises a shaft having a threaded portion and a portion for attachment to said armrest; a main member having a hole therein for accepting the threaded portion of the shaft, the main member being fixedly attached to said seat portion; and means for engaging the threaded portion of the shaft and fixing the relative position between the shaft and the main member; a backrest; means for tiltably supporting said seat portion on said height adjustable support means; means for tiltably supporting said backrest on said height adjustable support means so that independent movement of said seat portion relative to said backrest is provided, and so that the relationship between said seat portion and said backrest may be continuously and independently varied; and a removable support means for supporting a user\s knees and calves, said removable support means being removably attached to said base, so that independent movement of said seat portion allows alternating use of said removeable support means and said backrest.
