General Information
The eXtended Life (XL) product line has been replaced with the King Koil World Extended Life collection.
Original Product Description:
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.
