Hi Bazinga,
Your question has good timing because they are they are currently selling some seconds listed here.
Not to my knowledge no but you could certainly ask them to find out for certain.
You can see some thoughts about their vZone in post #4 here but because their zones can be customized to suit the shape and weight distribution of the individual person they would certainly more beneficial because if a particular zoning combination isn’t suitable for someone it can be changed to one that is.
