Temporary beds, also known as cots (4 letters), are a type of bedding that is designed to be easily moved and stored. They are often used in places such as campsites, hospitals, and military barracks, where space is limited and beds need to be quickly set up and taken down. Cots are usually made of metal frames with a canvas or nylon fabric stretched across the top. They are lightweight and can be folded up for easy storage.
