Walmart carries a wide variety of air mattresses, which are inflatable beds that are designed to be used as temporary sleeping accommodations. Air mattresses are typically made of a durable, airtight material, such as vinyl or rubber, and are inflated using an air pump. Air mattresses can be used for a variety of purposes, including as a temporary bed for overnight guests, as a camping bed, or as a backup bed in case of emergencies. Walmart offers air mattresses in a range of sizes, including twin, full, queen, and king, and they are available in both raised and standard height options. Some air mattresses also come with additional features, such as built-in pumps, memory foam tops, or built-in headboards.
