An air mattress is an inflatable mattress made of plastic or rubberized fabric. It's filled with air to provide a comfortable sleeping surface. Think of it as a portable bed 🛌, easily inflated and deflated. It's often used for camping, guest beds, or temporary sleeping arrangements. Unlike a traditional mattress, it can be easily stored when not in use. It's like a 'bed in a bag', ready to inflate for a good night's sleep.
