OK thanks all for the info...
I'm going to get one, now I just have to decide what thickness and if I should get the RV King size.
A recommendation: Go to Bed Bath and Beyond. Buy the lowest-price one, bring it home and try it out. If it doesn't feel good enough, bring it back and return it (Yes - they will let you do that!) and buy the next most expensive one. Repeat if necessary. When I bought mine they had three price-points, and I ended up with the middle-priced one. Love it. Would never go without one now.
