(Extended Life is a King Koil model designed to have superior durability, but owner experience data for this model is currently lacking.)|
|Price||B-||The price range is $350-$2,800 depending on size and model, not including a foundation.|
|Less (back) pain||c||See mattresses and pain relief for general analysis.|
