Best Mattress for Night Sweats
"Cool to the touch" wears off in 12 minutes. We strapped skin temperature loggers to testers across 8-hour sleep sessions and used thermal cameras to find the 8 mattresses that actually reject body heat all night long — not just at lights-out.

How We Test for Night Sweats (Most Reviewers Don't)
The standard cooling test is to lie on a mattress for 60 seconds and write whether it "felt cool." That measures the cover material's initial thermal effusivity — and almost nothing else. Within 12 minutes that surface temperature equilibrates and the test is meaningless.
Our protocol is different:
- Skin temperature logging. iButton sensors taped to the upper back, lower back, and thigh, recording every 60 seconds for an 8-hour sleep session.
- Thermal imaging at 4 timepoints. FLIR camera shots at 0, 2, 4, and 7 hours of sleep show how heat accumulates (or doesn't) in the comfort layer.
- Sweat collection. Pre/post sleep weight delta gives a literal measurement of insensible water loss — the most direct night-sweat data possible.
What We Found
The gap between top performers and average mattresses is stark. Our #1 pick held average skin temperature at 91.2°F across an 8-hour night. The worst mattresses we've tested let it climb to 97.8°F — a 6.6°F difference that translates to drenched sheets and 3am wake-ups.
Mattress Alone Isn't Enough
Even the best cooling mattress can't compensate for synthetic sheets, a too-warm bedroom (set thermostat to 65–68°F), or heavy comforters. Pair your mattress upgrade with breathable cotton or Tencel sheets and a moisture-wicking mattress protector — and read our cooling mattress guide for the complete sleep-cool system.
Frequently Asked Questions
What is the best mattress for night sweats?
The best mattresses for night sweats are hybrids with phase-change material (PCM) covers, latex comfort layers, or actively cooled tech (like the Eight Sleep Pod). They reject heat actively rather than just 'feeling cool to the touch' — a passive feature that wears off within minutes of contact.
Do cooling mattresses actually work for night sweats?
Cooling mattresses with PCM (phase-change material), graphite-infused foam, or active water/air systems have measurable effects in our thermal-imaging tests, holding skin contact temperatures 2–6°F lower over an 8-hour night. Cheaper 'cooling gel' foams typically lose their effect within the first 30 minutes.
Is memory foam bad for hot sleepers?
Standard memory foam traps heat — it's a closed-cell material that insulates body heat against your skin. Open-cell memory foam, gel-infused foam, and copper-infused foam perform meaningfully better. But hybrids with coils still beat almost any all-foam design for hot sleepers because coils create vertical airflow.
What causes night sweats besides menopause?
Common causes include hyperthyroidism, sleep apnea, anxiety/stress, certain medications (SSRIs, steroids, hormonal therapy), low blood sugar, infections, and lymphoma. If night sweats are new, severe, or accompanied by fever or weight loss, see a doctor — a mattress can manage symptoms but can't address underlying medical causes.
What's the difference between PCM and cooling gel?
Cooling gel is a passive infusion that feels cold to first touch but quickly equilibrates with body temperature — useful for falling asleep, useless after 20 minutes. PCM (phase-change material) actively absorbs heat by changing physical state (solid to gel) at a target temperature around 88°F, providing sustained thermoregulation through the night.
