I am a back sleeper and I had been experiencing pain on a daily morning basis with my old mattress. I was so worried buying this mattress just because I wanted something worth my money. It’s so comfortable and i have so much back and neck pain but this has truly reduced the pain. So far I don't find it to be a heat trapping mattress. I will of course update this review anything changes or unreasonably degrades, but hopefully it won't.
