Latex mattress warranties reflect the twenty year time frame that can be expected from a premium natural latex mattress. 100% natural latex provides the finest sleeping surface for comfort, reducing pressure points and durability. A natural latex mattress will generally use an organic cotton cover with natural wool batting, which will pass the current 2007 fire codes, and remain free from chemical fire-retardants.
Remember, a little extra care will go a long way in maintaining a high quality latex mattress. Let's start with the latex itself. Most importantly NEVER expose natural latex, without a cover, to direct sunlight. If you left just the latex itself outside in direct sun, it would begin to dry out and crumble in just a few days. Also, do not use a heating blanket on high heat directly on a latex mattress, as the trapped heat over the latex will eventually cause it to dry out and begin to breakdown.
To a lesser degree, try and position a natural latex mattress away from external heat source, particularly radiators or similar wall heaters. It is not necessary to rotate or flip latex, body impressions are unusual in high quality latex, even over long warranty periods.
