When choosing a camping mattress, consider factors such as comfort, durability, size, weight, and ease of inflation and deflation. Look for a mattress that is designed for camping and can withstand outdoor conditions.  Hikers or backpackers will fare best with a lightweight option, while those who love luxury or more comfort might prefer something more like their bed at home.  Also, consider whether you want a self-inflating model.  Double height can make it easier to get on and off the air bed, but may not fit in smaller tents with sloping sides.
