So easy to use! Simply add the recommended amount of water through the filler cap, and you're on your way to cool town! No refrigeration or electricity required. Unique cool core diverts liquid better than ever throughout the bed for advanced cooling power. For indoor use, use on hard flooring rather than carpet, which absorbs heat. If using outdoors, keep out of direct sunlight.
