    Abstract: The floating water bed includes a specially designed unique sleeping bag and a movable mattress pad. The sleeping bag is both thin and soft and it is placed on top of the movable mattress pad. This movable mattress pad can be lowered or risen from the water. As the human being rests within the sleeping bag, with the press of a button, the mattress pad can be lowered into the water along with the sleeping bag and the individual inside. At this time, the individual inside the sleeping bag will be floating in mid-water and will begin experiencing soothing relaxation. The floating water bed will have a well-shaped hole perpendicular to the sleeping bag and rising out of the water, providing the individual with an entrance into the sleeping bag as well as a breathing space once they are within the sleeping bag. With this well-shaped hole, the individual can breathe easily without the use of oxygen masks or additional equipment.

A thin flexible cooling mat is positioned upon a lounge chair or is placed flat on the ground or worn in the manner of a vest. Ordinary tap water circulates through the mat, and since the water is supplied from a conventional in ground supply main having a substantially lower temperature than the air, the person's body, in direct contact with the mat, will be kept cool. The cooling water may irrigate the backyard at the same time.

  • Patent number: 4242766
    Abstract: This invention provides a bed assembly having a thermally absorbent mattress such as a water-bed in thermal conductive relationship with a thermal-panel mattress bin arrangement receiving the mattress. Thermal energy transfer bath for cooling and heating is then attained by circulating a fluid of proper temperature through the thermal panel. The fluid temperature is established with environmental solar and ground heat to reduce needs for fossil fuel energy. Thus, an efficient temperature controlled bed is provided which permits nighttime comfort without control of the temperature throughout a house.
