Whether you live in the tropics or you're just a sweaty sleeper regardless of the temperature, trying to get comfortable at bedtime can be a nightmare. 

We test many mattresses each year, assessing them for things like comfort, stability, sagging, comfort retention and firmness. We also test each mattress's warmth: how warm or cool they are to sleep on. 

In previous tests, we've found that some supposedly 'cool' mattresses haven't lived up to their names. Though we've found a few 'cool' mattresses that genuinely are cool, most mattresses tend to run medium-warm or warm, which can be an issue if you're a hot sleeper.

The good news is that some of the mattresses coming through our labs are now actually living up to their claims, so your dreams of a cool night's sleep could well be in reach. 

"If you run hot, or you live in a warmer climate, look for mattresses with 'cool' insulation in our results. We know they can help you sleep cool because we measured them," says CHOICE mattress expert Peter Zaluzny.

However, there are still plenty that don't deliver on their promise, so make sure you check our reviews before buying so you don't get hot under the collar once you realise your mattress is warmer than advertised. 

We'll talk you through what makes for a cool mattress  and for CHOICE members, we'll reveal the best mattresses to keep you cool at night. If you just want to see the best products, you can jump straight to the results now.

Why buy a cool mattress?

Just like being too cold at night, being too hot can also disturb your sleep. If you overheat, you'll probably spend the night tossing and turning, and wake up feeling tired. 

While you can adjust your bedroom temperature and bed linen, sometimes that's just not enough. Buying a mattress that helps keep your body temperature lower is another way you can tweak your sleeping environment to help you rest better. 

"Mattress manufacturers often make claims about the warming, or cooling, capabilities of their products, but our tests found that it can be just marketing speak," says Peter. 

However, we're now seeing mattresses that actually do deliver a cooler surface temperature. We don't report on manufacturers' marketing claims, just the actual data, so when we say a mattress is cool you can be sure that it really is. 

What makes a mattress cool or warm?

Mattress manufacturers aren't always forthcoming about how their mattresses deliver a cool night's sleep, using vague terms like "cooling gel" and references to air flow, so it's hard for the average consumer to determine whether a 'cool' mattress will live up to the hype. 

Mattresses come in a range of different constructions and materials and, depending on who you speak to, you might think that a latex mattress is best, or that a spring mattress will breathe better. 

When we tested the coolness of each mattress we found that cool mattresses come in a range of different configurations – latex, foam and spring mattresses alike measured as cool. So, unfortunately, buying based on the mattress construction alone won't guarantee you a cooler sleep. 

But if you check our reviews before you buy you can make sure you're buying a mattress that will actually help keep you cool. You can also sort by price, construction, tested firmness and how you can buy it: online, instore or mattress-in-a-box. 

The coolest mattresses in our tests

We recommend mattresses with a CHOICE Expert Rating of 75% or more (although mattresses that score between 70% and 75% are still worth considering).

The coolest of the cool

These mattresses were all rated as 'cool' or 'very cool' in our expert tests, and they're also the highest-scoring cool mattresses of the bunch – so if you're after a cool and comfortable night's sleep, these are the ones to pick. 

Active Sleep Control

  • CHOICE Expert Rating: 79% (Recommended)
  • Price: $399
  • Insulation: Cool
  • Firmness: Firm
active-sleep-control_2

The Active Sleep Control mattress

Not only does this mattress cost less than $400 (RRP), it's among the top performers in our test. It has good overall comfort out of the box with minimal change over time and its very good at repelling sweat as well. In other words, the Control mattress will keep you cool and dry.

It doesn't offer a free trial period, however. So rather than buy online, head into a store if you can to try before you buy, as you can't return the mattresses unless there's a fault covered under warranty.

Breeze Firm Queen Mattress

  • CHOICE Expert Rating: 79% (Recommended)
  • Price: $479
  • Insulation: Very cool
  • Firmness: Firm
breeze-firm-queen-mattress_4

The Breeze Firm mattress.

You'll definitely sleep well on this mattress: not only is it the one of the highest-rating mattresses that's recommended by our experts, it's also among the cheapest on sale ($389), so you can rest easy knowing you've snagged a great deal. 

Plus it's rated as 'very cool' so it ticks all the boxes for hot sleepers looking for an affordable, comfortable mattress. 

The one downside is that it only has a one-year warranty. However, it sustained very little damage or wear after a simulated eight years' use in our testing, so it'll most likely last well beyond that one year anyway.

Ecosa Pure (2023 model)

  • CHOICE Expert Rating: 79% (Recommended)
  • Price: $1700
  • Insulation: Cool
  • Firmness: Adjustable (tested in medium-soft configuration)

The Ecosa Pure (2023 model) mattress.

Though the RRP is on the steeper end compared to other models in our test, it's still worth considering Ecosa's mattress. Why? Aside from sharing equal second place in our test, it's often on sale for a reasonably good discount. In fact, Ecosa was selling the queen-sized Pure mattresses for $1190 at the time of writing.

We found almost no change in male and female body support over time, and there are minimal signs of sagging. So, if this mattress feels right for you during the 100-night free trial period, then it should feel almost identical in eight years' time.

You can adjust the firmness between medium or medium-soft (we tested in the medium-soft configuration) and remove the cover for washing. This feature should extended the longevity of the mattresses, saving you money in the long run.

  • Firmness: Firm

The Ikea Vesteroy mattress

Sleepers that run hot will love two thinks about Ikea's Vesteroy mattress – it's very cool and, perhaps more importantly, it's very cheap. The second cheapest model in our test and the cheapest one to earn a Recommendation.

Just because the price is right doesn't mean you have to blind buy, mind you. Ikea has a massive 365-day trial period as well as a number of stores across the country. So those living nearby have the option to pop in and try one on the show floor before laying down your cold, hard cash on this cool, cool bed.

  • Firmness: Adjustable (tested in firm configuration)

The Zenna Latex Mattress.

This foam latex mattress came third in our test and while it's not cheap, it definitely delivers on comfort and coolness. It also comes with a 25-year warranty, which is reassuring if you're nervous about dropping so much money on a mattress. 

After putting it through rigorous tests, our expert testers found that the mattress showed minimal signs of sagging or damage, and it stayed almost as comfortable after eight years' simulated use as it was brand new.
