In [[camping]], a '''sleeping pad''', '''sleeping mat''' or '''ground pad''' is a simple device often used in conjunction with a [[sleeping bag]]. Its purpose is to provide padding and [[Heat#Heat transfer mechanisms|thermal]] insulation. The ground may become quite cold at night, and is often covered with [[stick]]s, small [[Rock (geology)|rocks]], and other objects that may make sleep difficult. A sleeping bag does not provide adequate protection against either hazard, but a sleeping pad does. | In [[camping]], a '''sleeping pad''', '''sleeping mat''' or '''ground pad''' is a simple device often used in conjunction with a [[sleeping bag]].

The simplest sleeping pads are sheets of [[foam rubber]], [[closed cell foam]] or a reflective metallized plastic material, rolled up or folded for storage. The latter provides little extra comfort, but gives good insulation. It is popular because of its low mass and volume. More expensive, and heavier, inflatable models are designed with interconnected air cells that may be compressed for maximum compactness, or inflated through a | The simplest sleeping pads are sheets of [[foam rubber]], [[closed cell foam]] or a reflective metallized plastic material, rolled up or folded for storage.

Self-inflating [[air mattress]]es are available for [[Backpacking (wilderness)|backpackers]], e.g., [[Insulmat]] & [[Therm-a-Rest|Therm-a-Rest®]]. As a partial misnomer, these pads will only inflate to the ambient air pressure, and usually will need a couple of breaths of air into the chamber to firm up the sleeping surface. There are two types of self inflating air mattresses; edge bonded and fully bonded. Edge bonded sleeping pads have the fabric bonded to the self inflating foam on the edges,as the name implies, and are cheaper to build then fully bonded mattresses. If there is too much air added to the chamber, these pads will "pillow" up in the center, and is why it is best not to blow air into them. Fully bonded pads have the fabric bonded to the foam on all sides. These offer superior comfort and a smaller packed volume than traditional foam sheets, however these are more prone to puncture. | Self-inflating [[air mattress]]es are available for [[Backpacking (wilderness)|backpackers]], e.g., [[Insulmat]] & [[Therm-a-Rest|Therm-a-Rest®]].
