Hi tm,
Post #2 here may give you some insights into the reasons why your Celebrate is sleeping warmer for you.
Sleeping temperature can be the result of a combination of factors that work either for or against temperature regulation but besides factors that may be connected with your environment or your own body or circumstances … the most likely candidates based on your comments would be one or more of …
-
The protector you are using (the thinner membrane types are less breathable than either stretch cotton or wool)
-
The material in your sheets (natural fibers like cotton or linen or semi synthetic fabrics like bamboo tend to be cooler than polyester or synthetic blends).
-
The thickness and softness of your comfort layers. Even though Talalay latex is more breathable than other types of foam … if you are sinking in more deeply to comfort layers that are are fairly thick and soft (5" in the case of the Celebrate) then any foam will act as an insulator to some degree … especially with a less breathable protector or sheets over it.
