Hi JBR2022.
It may or may not be helpful for you, but you can find all previously existing convos about Ghostbed Luxe mattresses via this keyword search. Keep in mind that temperature regulation has multiple variables, including the bedding you use on your mattress, and your own sleepwear. If you haven’t been given the “spiel” on mattress microclimates, you can find that in Phoenix’s reply here.
