The Saatva supposedly sleeps the coolest because of the breathable materials used, and I get hot when I sleep. Since I'm a stomach sleeper I think this would be the best option for me
The Rx is waaaaayyyyy softer than the Memory Foam hybrid. Maybe cause I am a lot lighter than him, but it is night and day. I would never give them the same rating. I live in a city with a showroom, so I have rested on most models. I went with Memory Foam hybrid. It was my favorite and it just happened to be the cheapest. I don’t really get how it’s cheaper than the Classic, but I am not asking any questions.
