After a fair amount of testing and research on this site, thanks Phoenix for all that you do, i ended up ordering the flobeds vzone. I really wanted the ultimate in flexibility to get my comfort and sleeping position right. I expect it to arrive in a little less than 2 weeks and will follow up with a review if others care to read. Hopefully the set-up will be close out of the box and i will only have to do minor tweaks. Dewey at Flo has been very helpful and emphasized to call if we are feeling any problems so he can offer suggestions to try to improve it. It sounds like there are many options to re-configure before sending out new components. 
excited for a better rested night with no sore back in the morning!
