Hi pdunc,
Thanks for taking the time to share your comments and feedback.
You’re right that latex is a very breathable material and sleeping temperature issues with a latex top layer is somewhat unusual.
While it’s not always possible to to track down temperature regulation issues for any particular person on a specific mattress because there are so many variables involved (including your room temperature and humidity, your sheets and bedding and bedclothes, your mattress protector or any mattress pads you are using, and where you are in the “oven to iceberg” range) and some people can sleep warmer on mattresses that most people are generally fine with … there is more about tracking down a potential cause or causes for temperature regulation issues (at least to the degree possible for a specific mattress) in post #2 here and the posts it links to that may be helpful.
It’s also possible that your mattress pad could be contributing to any temperature issues as well.
