I decided to buy the most expensive mattresses on the market because I wanted to sleep well. I tend to run hot, so I opted for the cooling mattress. It's the opposite. I get so hot that I have to change positions where the bed heats up almost every hour at night. I'm so disappointed and sad because now I am stuck with this expensive mattress. We bought it in 2019 and I thought things might get better....but no. I DO NOT RECOMMEND getting this mattress.
