Hi Harmful,
If a mattress is a good match for you in terms of PPP then how “basic” the design is makes no difference at all.
There is more about convoluted foam in post #2 here. Convoluted foam underneath memory foam can have “some effect” on ventilation and sleeping temperature but the effect would be greater if there was also a pathway for the air to go through the memory foam layers into the convoluted channels below it and out to the environment and it would also depend on how much the air channels compress or “close off” when you sleep on them so the effect may be minimal (see post #2 here about cooling down memory foam). How much effect it has would depend on how much airflow there is through the top memory foam layers and on the combined effect of all the other variables that can affect sleeping temperature as well (see post #2 here).
