Best mattress choice

I am trying to decide between these two options. Price doesnt matter to me here, as this will last me a while.



Other suggestions are welcome!

I always worried about foam. I hate hot mattress.

Which one is the coolest?

The second one I believe as it mentions being ventilated and cool gelled.

We just got a Simmons. Supposed to have all that. Still gets hot at times.

I have been looking at a special mattress pad cover at number bed. It has a fan and does cooling like a car seat. Very expensive. But if you run out of choices. Sometimes being hot all the time affects life's quality
