The concept, design and name of the King Koil Extended Life brand address concerns of consumers over the durability and longevity of mattresses and beds. The "Extended Life mattresses are built for indestructible comfort." Terms used in describing this line of innerspring mattresses include "heavy-duty" and "extra-strength." These mattresses and foundations "are built to last." One no longer has to sacrifice comfort for durability.
The modified offset coils in Extended Life mattresses are made of 12½ gauge wire, definitely heavier than most coils on the market. These are shaped to also be responsive to lightweight persons. King Koil uses heavier-than-usual foams in the comfort layers of Extended Life mattresses, including the memory foam, polyurethane and latex components. In the top layers, cooling gel foam and graphite latex compensate for heavier construction to counter heat buildup.
King Koil encircles the innerspring with Excellent Edge FE, a heavy-duty foam encasement. This is edge support for the sleeping surface to keep the edge from sagging. This increases the "usable sleeping surface" by 10%. The cover fabrics of Extended Life mattresses by King Koil wick moisture away to keep the sleeping surface dry.
King Koil supplies its Superior Extended Life Foundation (sold separately) for use with the Extended Life models. This is a sturdier version of regular wood-framed bases, with 2½ times as many slats and 3 times the beams. The heavier foundation protects the mattress from breaking down. Covered with fabric, it matches or complements the mattress.
King Koil underscores the stated longevity of mattresses under its Extended Life brand by issuing a 25-year warranty with the the first 15 years not prorated.
