Abstract
A dual layer inflatable sleeping pad has an upper inflatable layer coupled to a lower inflatable layer. The dual-layer sleeping pad has an inflation valve for the lower layer and a second inflation valve for the upper layer. These valves are in fluid communication with their respective layer, thereby allowing air to travel in and out of each layer as needed. Each layer is independent from one another and the inflation level of each layer can be independently adjusted.
