Hi LA47,
There are many factors that work together which affect the sleeping temperature of a mattress and while you’re waiting for any replies from other members … post #2 here may be helpful.
Your choice of a mattress protector, a wool or other more breathable mattress pad, or different choices in the type of sheets and bedding you have can also have a significant effect (in either direction) on the sleeping temperature of a mattress that can play just as important a role as the actual foam or the ticking and quilting in the mattress itself.
