Query: duro-rest water pillow

pillow came promptly.pillow is too large. my wife, lying on her side, her head on pillow was not level.I took the water sack and stuffed it in a king size pillow case with an old smaller pillow and a large folded towel under the water water sack She finds this very comfortable.I'm surprised the pillow is so big. I think it's too big for me, an average male. For the low price I don't mind just using the water sack. I think a major redesign of this pillow is needed.
