Best Cooling Mattresses on Amazon 2025: Stay Chill All Night

Cooling used to mean a thin gel swirl poured into inexpensive foam. This year’s Amazon favorites pair conductive materials—graphite, copper, phase-change yarns—with open-channel cores that circulate air. The result is a mattress that feels cool to the touch initially and stays temperature-neutral once your body heat equalizes.

When you shop, look for transparency: cubic feet per minute (CFM) airflow ratings, thermal conductivity numbers, and verified reviewer comments logged during peak summer. Brands that publish those data points typically deliver consistent cooling instead of marketing fluff.

Use this comparison to shortlist mattresses before reading full product pages. Prices reflect Q4 2025 queen sizes and fluctuate with Prime deals.

Gel is great at absorbing heat quickly, but it saturates unless paired with ventilation. Copper and graphite move that heat toward the mattress edges where airflow can dissipate it. Phase-change covers actively store and release energy, smoothing temperature spikes caused by hot flashes or hormonal changes.

Latex and coils rely on geometry: open-cell foam and pocket springs create natural channels. If you prefer all-foam beds, insist on perforated comfort layers plus breathable base foam or consider foam-hybrid hybrids that add structural airflow.

Measure your bedroom temperature after lights-out—ideally 60-67°F—and note humidity levels. If temps stay high despite HVAC, choose a mattress with active cooling (phase-change, copper, PCM covers). If humidity is the problem, latex or coil-heavy hybrids with moisture-wicking covers will feel less clammy.

Cooling mattresses reach full potential when you add breathable protectors, percale or Tencel sheets, and lightweight quilts. Avoid vinyl-backed protectors that suffocate airflow. For extreme heat, add a BedJet, ChiliSleep Dock Pro, or Eight Sleep cover—the best mattresses on this list have tight covers that work with climate pads without bunching.

Wash covers (if removable) with mild detergent only—fabric softeners can clog phase-change coatings. Rotate foam mattresses quarterly so airflow channels do not collapse in one zone. Vacuum surfaces monthly to remove dust that traps heat and restricts ventilation.

If body impressions deeper than one inch have formed, airflow is compromised and heat builds under the hips or shoulders. Likewise, if you upgrade bedding and HVAC yet still wake sweaty every night, the foam chemistry likely isn’t keeping up. Upgrade during Prime Day or Black Friday when cooling models drop 15–25% and bundles often include free cooling pillows.

Use twin XL comforters or duvet inserts so each sleeper can choose their preferred insulation. Stack a cooling mattress pad on only the hot sleeper’s side, and set ceiling fans to rotate counterclockwise to push air downward without chilling the entire room.
