The Bottom LineBoth these mattresses have an all-foam construction with memory foam layers. Both are on the softer side of the comfort scale but Tempurpedic sinks a lot more than Puffy. Especially, if you are on the heavier side, you run the risk of bottoming out. Puffy is cooler and offers comparable comfort and support. Being cheaper, Puffy offers you better cost-based value than Tempurpedic Cloud Luxe.
