Holes actually came from stupid managers who started to imitate solid latex that requires holes for vulcanization (not for better ventilation!).

Even in all rolled latex holes are made specifically (by idiots) to play on people limited knowledge and make it look like latex. Such thin latex is vulcanized only by two sides, not require any holes and using completely differently looking machines.

In memory foam 99% of all ventilation comes from proper structure, and even with it memory foam is always worst ventilated foam as it is tightly compressed near your body almost blocking any air in and moisture out. Btw any gel infusion and such is also fake shit, as it make foam feel cooler for limited amount of time, until temperature of gel particles will rise :-)
