The eXtended Life (XL) product line has been replaced with the King Koil World Extended Life collection.
The XL or eXtended Life Mattress Collection has been specifically designed to meet the needs of plus-size sleepers. Many plus-size sleepers find that their mattress is uncomfortable, unsupportive and that it tends to wear out quicker. The XL Collection alleviates these common problems with thoughtful engineering to provide a comfortable feel, enhanced support and increased durability. As proof of the XL Collection's quality, it even comes with a 15-year warranty against defects.
