Suteetat
The description from the TW site states this
Yamada-san of Zanden Audio, Japan, has developed a 5 mm thick compound mat for us, and it has totally won us over. The mat consists of two different layers of rubber. The harder of the two compounds sits directly on the turntables platter. The softer upper surface generates adhesion and thereby creates a perfect connection between record and turntable. The incomparable dynamics that distinguish our turntable from the rest remain fully unnrestricted, but the musical reproduction appears clamer and more composed because there is now no perceptible pickup noise at all. In addition, the mat lends the music an aura of silkiness and exclusive musicality.
So from the above descrition it is a one sided mat, but dual density with the soft layer intended to face up.
Right now I am using my TW with out a mat. I only have experience with the Millenium mat. But I will eventually get the new TW/Zanden mat one of these days.
