Hypoallergenic, yes. But not Bed bug/ waterproof etc. Had to buy a different brand to put on before I put these cases on. Though they are quiet and don't disturb my sleep.
Bought this for my husband for his knees and back issues. He hugs it to keep his knees from knocking and to soften his back. Pretty big to use on a queen bed that we share, need to use on a king.
