Hi SeaLifeLover,
You can see my comments about WinkBeds in post #2 here of the simplified choice mattress topic and in this topic. A forum search on Winkbeds (you can just click the link) will also bring up more comments and feedback about them as well.
I don’t have any personal experience with any of the Charles P Rogers mattresses but their Powercore pocket coil is a good quality component that certainly wouldn’t be a weak link in any of their mattresses (the weakest link of a mattress is generally in the layers above the innerspring, not the innerspring itself). A forum search on powercore 7000 and on powercore 9000 (you can just click both links) will bring up more comments and feedback about both of them and about Charles P Rogers in general. While I can’t speak to whether either of them would be a good match for you in terms of “comfort” or PPP … with the extra layer of latex the 9000 would be softer than the 7000. Both of them use good quality materials and there would be no weak links in either of them in terms of durability.
I’m looking forward to finding out what you end up deciding.
