it's good to hear that your wife got rid of CTS, but generally the problem in the carpal area is one of pressure -- there is a bundle of nerves, tendons, blood vessels, etc., that go through the wrist. It's common for compression to cause problems. My wrist doctor advised me to avoid any pressure at all, because you can feel comfortable (e.g. with a pillowy surface) while still doing damage.
