An inflatable bed is a type of mattress that can be filled with air to provide a sleeping surface. These beds are often made from durable materials like vinyl or PVC and can be easily deflated for storage or transport. They are popular for camping, guest accommodations, or temporary sleeping arrangements. Inflatable beds come in various sizes, including twin, queen, and king, to suit different needs. Many models feature built-in pumps for quick inflation and deflation. Some also have added comforts, such as flocked surfaces for a softer feel, making them a convenient alternative to traditional mattresses.
