I’m disappointed in how firm this mattress is. I slept on an original T&N mattress- not a hybrid- and now I wish I hadn’t upgraded to the hybrid. Worst of all, I gave my original away so I can’t go back to sleeping on it. Wish there had been a store I could’ve gone to test the mattress before I purchased it. It’s also not as “cooling as I expected. I still feel heat from the mattress when I’m sleeping- not quite as intense as the original
