Hi jpayan,
Thanks for taking the time to share your comments and feedback … and a belated congratulations on your mattress 
It’s great to see that your choice worked out so well for you.
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.
Your mattress protector could certainly be playing a noticeable role in your sleeping temperature and there is more about the pros and cons of different types of mattress protectors and some examples of each of them in post #89 here.
Other variables that can affect your sleeping temperature besides the mattress itself would be the type of sheets you are using, your blankets, your room environment, and the bedclothes that you sleep in.
