Cooling mattresses 8 inch

I love it for my single bed in the efficiency apartment. I should’ve got the 10 inch but this does just fine. I get very hot when I sleep. It is very good for that. I would suggest 100% cotton sheets or linen as I got. as soon as I switched it to cotton is much happier it does fine for a guest bed. I would recommend a 10 inch for a regular sleep, but I am happy with the 8 inch. It’s fine
