What is Audi A8's optional massage function and how does it work?

I've read about the optional massage function for the Audi A8, but I'm not sure how it actually works. Can someone explain it in detail?

The optional massage function in the Audi A8 is a feature that allows the driver and passengers to receive a relaxing massage while on the road. The massage function uses 10 different air cushions in the seats, which can be adjusted to provide different massage patterns and intensities. It also includes a heating and cooling feature for maximum comfort. Overall, the massage function is a great way to unwind on long drives or during heavy traffic.

Having used the massage function in my own Audi A8, I can say that it is worth every penny. Not only does it provide a sense of relaxation, but it also helps improve circulation and reduce muscle tension. I've even noticed a decrease in back pain during longer trips. I highly recommend it as an optional add-on for the A8.
