What we found
- Category cooling scores rank Latex 9.04, Airbed 8.65, Hybrid 8.6, Innerspring 8.59, Memory Foam 8.36.
- These cooling scores are editorial ratings of construction, airflow and cover materials applied under one rubric. No mattress in the database currently has a published surface-temperature measurement, so none is reported here.
- Coil-based constructions win because air moves through the support core. All-foam beds fight the same physics with gel, graphite and open-cell structures, and the best of them close much of the gap — but the category average still trails.

The highest cooling scores in the database
Our cooling rating weighs airflow through the support core, how deeply the comfort layer lets you sink, and the cover and quilting materials. It is an editorial judgement applied under one rubric, not a temperature reading.

What actually makes a mattress sleep cool
Three things dominate: how much air can move through the support layer, how far you sink into the comfort layer, and how quickly heat can leave the surface. A pocketed-coil or latex core keeps air moving under you; a deep memory foam cradle wraps the body and traps heat against it regardless of what the cover is made of.
Phase-change covers and gel infusions are real but short-acting. They pull heat away for the first part of the night and then saturate, which is why a cool-to-the-touch panel can still be a warm bed at 3am.
Method
Every mattress is assigned to a construction family from its published type. We averaged the cooling score within each family with at least three reviewed models.
Cooling scores are editorial judgements of airflow through the support core, sink depth and cover materials, applied under one consistent rubric. No surface-temperature measurements are published for these models.
Limitations
- None of the 202 mattresses in the database currently has published instrument readings, so every figure in this study comes from our editorial ratings, published specifications and recorded prices. No number here is a laboratory measurement.
- Temperature rise is measured on a bare surface in a controlled room. Your sheets, mattress protector, duvet and bedroom temperature can matter more than the mattress itself.
- Our category scores are editorial judgements applied under one consistent rubric, not laboratory constants. Where a lab measurement exists we report the instrument reading alongside the score so you can check the two against each other.
Frequently asked
What is the coolest type of mattress?
Coil-based constructions — hybrids, innersprings and latex hybrids — measure coolest in our testing because air moves through the support core. All-foam beds trap more heat against the body, and the deeper the cradle the warmer they run.
Do cooling mattresses really work?
Cooling covers and gel infusions measurably lower surface temperature early in the night, but most saturate after an hour or two. A construction that lets heat escape continuously matters more than a cool-to-the-touch panel.
Is memory foam always hot?
No. The best all-foam beds in our thermal testing perform close to average hybrids thanks to open-cell structures and perforation. The category average still trails coil-based builds.
