Abstract
Attachments and adjustments are applied to conventional chairs which provide a knee rest normally positioned in a retracted position beneath the seat cushion. Special mechanisms permit withdrawal of the cushion to a position facing the seat cushion and tilting the seat cushion to permit use of the chair in a knee rest position and provide for return of the cushion to its original position. Related mechanisms provide for corresponding adjustments to the seat rest and the back rest to effect conversion of the chair from conventional to other uses. The latter include adjustment of the seat rest and back rest to convert the chair for use in a lounge position.
