The ironically designed moon sun lounger has been designed in a shape of the moon with great functionality to provide most comforting sunbath. The most advantageous point of this transparent and easily manufactured lounger is it can tan the body from back side as well by reflecting sunbeams through its water filled bottom part. At the same time, the air around the body remains cool through the vaporized water over time, giving a soothing feeling to the user. The shape of bottom and weight of water gives the user a pleasing cradle swinging experience after a small nudge. To make the sunbathing more entertaining, the lounger contains different size holds where any kind of beverage glasses can be kept.
