Bought this on a whim during Black Friday - Cyber Monday weekend. My partner and I knew we could benefit from a mattress topper since we have back and joint problems and after reading other reviews, we figured we’d give this one a try. Three weeks later and we’re still very satisfied! Other customers were right about it being on the firmer side, but we like a firm mattress. It’s still very soft and supportive. My back, neck, and joints don’t hurt in the morning anymore! We haven’t really noticed any difference in it feeling cooler, but it’s also fall in IL, so we’ll probably not tell the difference until summer. I like it enough to buy another one for my mom and dad )
