Hi viper20,
There is more about the many variables that can affect sleeping temperature in post #2 here and while it’s not really possible to know this on an individual level because it depends so much on the temperature sensitivity and physiology of the person themselves … with the Talalay latex on top and the overall design of the mattress I don’t think that most people would have any temperature issues with this mattress no.
You will need a support system under the mattress (a bedframe and foundation or a platform bed) and the foundation post here has more information about the different types of support systems that generally work best for different types of mattresses.
You will also need a mattress protector and there is more information in post #89 here about the different types that are available and some of the tradeoffs that are involved with each type.
