You can really feel it!
It took a minute to actually get all of the pieces. Once I did, I could see a difference after the first night. I struggled to modulate my temperature on my own and the blanket/cover are perfect! You can really feel the temperature difference as soon as you get in bed. I was looking at the tempur pedic and the sleep number. I wanted to keep my mattress though because I really like it. 8 sleep was the perfect option for me!
