More warmth per gram than any other air mattress in the world.
The XTherm™ air mattress delivers the greatest warmth-to-weight ratio available in any air mattress by far, with a softer, textured no-slip fabric for better next-to-skin comfort and a quieter rest. Multiple, reflective ThermaCapture™ layers give the XTherm™ air mattress true four-season warmth without the weight or bulk usually found in a winter-worthy mattress. And now, the XTherm™ MAX delivers all the great features and benefits of the original XTherm in a full rectangular shape, providing added coverage and warmth for extreme temps and wider torsos.
