R,
Not exactly, but we have a Prana mattress set in the FLA joint,
and those two are very similar; my only beef is that the "foam"
sets tend to feel a little warm as they seem to really absorb
body heat while sleeping. My 2Cts...

Edit...here is the Prana link. It is slightly diff in construction
to the one you are looking at, but same idea, imo.
