Mattress for the Sports-minded and Highly Active?

Here's a new specialty mattress for those who are highly active: the Ironman mattress series.

According to a story in the Las Vegas Review-Journal, the mattress is "...designed to help people recover from the stress of daily life and a sleep system based on a scientific theory and diagnostic tool that evaluates how each person sleeps... The soy-based core is zoned to provide the most support in those areas where it is needed to keep the body in proper alignment. That is covered with layers of latex for comfort and to eliminate any pressure points. Finally, the mattress is covered in a fabric containing celliant, a specially formulated material that can be knitted, woven or incorporated into fabrics."

Sounds interesting, but I'm a bit skeptical of course. Read the whole thing.
