Suggestions for hot stomach sleeper

I'm wondering if anyone can recommend a mattress that fits the following criteria:

• low motion transfer (equivalent to a full memory foam mattress or better)
• high air circulation so the bed stays cool all night
• firm or extra firm which seems best for sleeping on your stomach

The Purple Hybrid seems to get close but it's not firm only medium so I have a feeling it won't work for a 100% stomach sleeper. Anyone have any other suggestions?
