Hi chip,
You can see my thoughts about it in post #2 here.
With only half the thickness of latex it’s not in the same value range as the Dixie foam but it’s also a different design which would have a different feel and performance so it may well be worth testing to see how well it worked for you in terms of PPP (Pressure relief, Posture and alignment, and Personal preferences) because it would be different from the Dixie foam latex hybrid as well and some people may prefer an innerspring/latex hybrid over a polyfoam/latex hybrid.
