a cushion comprising:
a front surface,
a rear surface,
side surfaces extending between the front surface and the rear surface,
at least one drainage opening extending through the side surfaces of the cushion for draining fluid from an interior of the cushion, wherein the rear surface comprises an annular edge defining a jet opening providing access to the interior of the cushion sized to at least partially cover the at least one jet, and
an annular shroud extending from the rear surface of the cushion and around the annular edge; and
a retainer assembly comprising an opening configured to align with the at least one jet and a peripheral edge that engages the annular edge of the cushion thereby providing an annular seal between the rear surface of the cushion and the retainer assembly,
wherein the annular shroud is configured to contact the retainer assembly providing an additional annular seal between the cushion and the retainer assembly, and
wherein the retainer assembly is configured to be removably fixed to a wall surrounding the at least one jet with the at least one jet aligned with the opening of the retainer assembly and the jet opening of the cushion, such that fluid expelled from the at least one jet passes into the interior of the cushion, so that the massage pillow provides at least massage and/or warmth due to the expelled fluid.

providing a cushion of the massage pillow, the cushion comprising:
a front surface,
a rear surface,
side surfaces extending between the front surface and the rear surface,
at least one drainage opening extending through the side surfaces of the cushion for draining fluid from an interior of the cushion, wherein the rear surface comprises an annular edge defining a jet opening providing access to the interior of the cushion sized to at least partially cover at least one jet extending through a wall of the fluid-containing vessel, and
an annular shroud extending from the rear surface of the cushion and around the annular edge;
connecting a retainer assembly comprising an opening configured to align with the at least one jet to the cushion of the massage pillow such that a peripheral edge of the retainer assembly engages the annular edge on the rear surface of the cushion, thereby providing an annular seal between the rear surface of the cushion and the retainer assembly, wherein the annular shroud is configured to contact the retainer assembly providing an additional annular seal between the cushion and the retainer assembly; and
mounting the retainer assembly to the wall of the fluid-containing vessel, such that the at least one jet of the fluid-containing vessel is received by the opening of the retainer assembly and is positioned to expel fluid through the opening of the retainer assembly, into the interior of the cushion of the massage pillow.
