Thermo Regulating Top Sheet The Thermo Regulating Top Sheet is placed on the bed as a normal sheet, with the white Thermo Regulating material on top, so that it is not touching the person in bed. This will prolong the life of the item best. It can be used the other way around, with the white Thermo Regulating material touching the person, but because using it this way will not protect the Thermo Regulating material, it may not last as long. The special white Thermo Regulating material is sewn onto a standard bed sheet, and there is some standard bed sheet material sheet near the pillow, so when the blankets are on the bed, the head section of the Top Sheet can be folded over the blankets. The Thermo Regulating Material should be wide enough to cover the person when they turn over, but we are not able to guarantee that they will always be covered if they disturb the sheet too much. Pelican also makes a Thermo Regulating Pillow Cover which may help control the person’s temperature, and can be used in conjunction with the Thermo Regulating Top Sheet. The Thermo Regulating Top Sheet is one item in Pelican?s Thermo Regulating range of items which includes the Thermo Regulating Mattress Cover, the Thermo Regulating Duvet Insert, and Thermo Regulating Pillow Cover.
