Hi nancymariec,
I’m guessing you mean this mattress?
Unfortunately their description is very incomplete but if if you can find out the information listed here and post it on the forum I’d be happy to make some comments about the mattress and the quality of the materials inside it. Without this information it’s really not possible for me to make any meaningful comments about any mattress.
Post #2 here has more information that may help you track down the reasons you are sleeping hot and some suggestions that may help.
