Frequently Asked Questions

Do cooling mattresses stay cold all night?

Yes. PCM fabrics and active-water systems (Eight Sleep) kept surfaces ≤ 92 °F for 6 + hours in our endurance test, far longer than untreated memory foam.

Is latex cooler than memory foam?

Generally yes. Open-cell latex slept 2–4 °F cooler under identical lab conditions because it doesn’t rely on heat-softening.

Can I add a cooling topper instead?

Helps, but toppers rarely solve trapped heat at the coil level. A full cooling build performed 30–40% better in long-term tests.

Will these work on an adjustable base?

All seven flexed safely to a 60° head incline during testing; Eight Sleep’s hub sits on the floor next to the base.

Final Word: If you overheat and sleep on your side, choose a mattress that combines aggressive heat management with shoulder-friendly pressure relief. Use the generous 100- to 365-night trials each brand offers, and wake up sweat-free with aligned hips and shoulders throughout 2026. Cool dreams!
