Definition & Meaning of "air bed"

What is an "air bed"?

An air bed is a type of mattress that is inflated with air to provide support for sleeping. It is typically made from durable, flexible materials like vinyl or rubber and can be adjusted for firmness by adding or releasing air. Air beds are portable and easy to store, making them popular for camping, temporary sleeping arrangements, or as a guest bed. Some air beds come with built-in pumps for easy inflation, and they can offer a comfortable sleep surface comparable to traditional mattresses.
