Hi Kellymckibkib,
You can see some of the tradeoffs involved with different types of mattress protectors in post #89 here that can help you decide which is is likely to be the best choice for your personal circumstances and criteria. All of these would be “suitable” for a latex mattress or any mattress.
You can also read more about the many different factors that together are involved in the temperature regulation of a mattress in post #2 here that can help most people deal with heat issues.
Talalay latex is the most breathable of the different types of foam materials so with a mattress that had a Talalay latex comfort layer you would at have the advantage of one of the factors being “cooler” than other types of foam.
