The average person sweats about 1 pint each night. That’s 365 pints/year. lol
I recently came across an old times article where the people over at Hastens and Magniflex used this fact as a selling tool. Just goes to show the importance of a breathable sleep surface.
Very few companies offer a truly cool sleep because it requires natural materials and fabrics….the expensive stuff. You tend not to find these natural materials in mattress made by big brands such as Sealy, Serta, King Koil, Stearns and Foster. They’re making absurd margins with cheaper materials, why would they change?
Natural, typically = breathable
Going with a specialty mattress brand is by far your best bet to getting the zzzzzz’s .
