For removable cushion-to-chair fastening, a region on the back side of the cushion is treated or covered with pressure sensitive adhesive (PSA) of sufficient gripping strength to hold the cushion in place without other support. The PSA element is an integral part of the cushion and allows the cushion to be reattached and readjusted multiple times, and can adhere to all manner of surfaces. The PSA material is of a type that can be washed with water and renewed or reactivated, regaining its full adhesive properties upon drying. A foldable rear flap may be provided that can be closed to cover the adhesive region and retained in the closed mode for storing, transporting and using the cushion in a conventional manner, and then opened and retained against the back panel in the open position for exposing the adhesive when the cushion is utilized in the open mode for chair-attachment. Alternatively, the closed mode could be implemented by a removable cover panel.
