Abstract: A device for retaining a towel on a beach chair includes a pillow member with a cover and a padding element, and an elastic strap member connected to the pillow at a number of connection locations on the back of the pillow. The elastic strap member is an essentially continuous loop of elastic material and is stretchable to encircle the back of the chair, such that when the device is in place, the strap is taut and acts to retain the towel on the chair. The device further includes additional connections between the strap and the pillow member to form flat item hiding locations for maintaining valuable items such as credit cards, ID cards, folded paper money, and the like, hidden by the pillow from ready public view.
