An inflatable mattress is a portable sleeping surface that can be inflated with air to provide comfort. Made from durable materials like PVC or vinyl, these mattresses are often used for camping, guest accommodations, or temporary sleeping arrangements. They come in various sizes, including twin, queen, and king, and can be easily deflated for storage. To use an inflatable mattress, you typically need a pump, which can be manual or electric. Once inflated, it offers a cushioned surface similar to a traditional mattress. Many models also feature built-in pumps for convenience, making setup and takedown quick and easy.
