A camp bed, or cot in North America, is a small portable, lightweight bed used in situations where larger permanent beds cannot be used. The main advantage of this bed is its portability and compactness. Camp beds are generally used by armies or organizations, in tourism, and in emergency situations when there is a need to quickly provide accommodation for victims.
The first camp bed were probably used by the Roman army. During the Soviet period, the lack of housing caused a massive use of camp beds that made them irreplaceable, iconic elements of the Soviet life.
