An air mattress, also known as an inflatable mattress, utilizes chambers filled with air as the primary support system. These mattresses typically come with an electric or manual pump for inflation and deflation, allowing users to adjust the firmness according to their preferences. Air mattresses are versatile and portable, making them ideal for camping, temporary guest accommodations, or as a space-saving option for small living spaces. They often feature durable materials such as PVC or reinforced vinyl to withstand regular use and provide adequate support. Some air mattresses also incorporate additional layers of foam or padding for enhanced comfort and insulation. With their adjustable firmness levels and convenience, air mattresses offer a practical solution for temporary or occasional sleeping arrangements.
