I'm a back and side sleeper, and I found the loft to be a little too high for sleeping on my back. I couldn't get my head level and it strained my neck. However, it was the perfect loft for side sleeping! For reference, I'm 5'4" and 115lb. It's also cool to the touch. It did have a bit of a smell, but aired out after a week or two.
So I bought the cooling memory foam gel pillow and it's pretty decent it's kind of thick it's a tidbit much for me but my boyfriend seems to like it when I do use it at night it does keep me cool I just wish it was a little tiny bit thinner not much dinner it's just too big for my neck but it works how it says it should with the coolness anyways
