A seating unit includes a seat, a back, and a support structure supporting the seat and the back. A wheelchair base frame includes a beam extending transversely across the wheelchair base frame. An adjustable extendable column extends between the beam and the support structure for adjustably supporting the seating unit on the wheelchair base frame. The support structure and/or the transverse beam can be constructed to receive the same structure as is provided on a standard task chair. By this arrangement, a plurality of similar chairs can be ordered, some having standard bases and others having a wheelchair base. Concurrently, the seating unit with the wheelchair base can include substantially all options and styling offered in the standard task chair.
