The super-high temperatures of summer 2022 are predicted to continue, and with some weather forecasts saying it may reach 40°C, getting a good night's sleep won't be easy. However, one way to beat the heat while you sleep is to invest in a mattress that is breathable and feels cool.
Your mattress can make all the difference to how hot and uncomfortable you feel in bed. We test every mattress's insulation properties - that’s how much heat they let through - as well as how breathable they are - that’s how much moisture the mattress fabric wicks away so you don't feel sweaty.
Below is our pick of the best cooling mattresses. They won't leave you feeling hot under the covers and they won't burn a hole in your wallet either. The average price of all mattress types we’ve tested hits nearly £600 - most of the mattresses listed below are cheaper than average (at the time of writing).
If you can’t quite stretch to a new mattress at the moment, or have just bought one, don’t worry - we’ve also got top tips to help you stay cool at night.
How warm or cool you’ll feel at night may not be the first thing on your mind when you're considering buying a mattress, but the fabric your mattress is covered with can make a big difference to whether you feel warm or cold when you first get into bed.
Below we highlight five double mattresses that will feel cool when you get into bed and have, at the least, acceptable breathability. To see how durable and supportive these mattresses are, you will need to read our full test reviews.
The budget-friendly Ikea Vadsö mattress is an open coil type made from a layer of Bonnell springs covered in matting and a 1.5cm layer of foam closest to the sleeping surface. Ikea says this mattress 'provides stable and even support, giving you the feeling that you're sleeping on top of the mattress rather than in it.'
This mattress is cool to lie on, and our independent tests confirm it'll provide a firm surface to sleep on, but will the open coil construction be too bouncy?
The Jay-Be Benchmark S3 Memory mattress is made from a combination of springs sandwiched between layers of fibrous web and matting, which Jay-Be says is made from recycled plastic bottles that provides 'a more environmentally friendly alternative to memory foam'. It's rated 'cold' in our tests, so it shouldn't make you super hot when you head to bed.
It's sold as a medium/firm mattress and our independent tests rated it as a four on a scale where one is very firm and 10 is very soft. But, eco credentials aside, will it give you a comfortable night’s sleep and stand the test of time?
The Silentnight Studio Eco pocket-sprung mattress contains ‘eco comfort fibres' which Silentnight claims make it super breathable, sustainable and recyclable. Rated 'very cold' in our tests, this would be a great choice if you tend to get hot and sweaty at night.
It's marketed as a medium-firm mattress. However, in our independent tests it's rated as 3.6 on a scale where one is very firm and 10 is very soft. Will it be supportive no matter what your favourite sleeping position is?
Like a growing number of mattresses, the Viva Supreme is made from multiple layers of springs and foams. We haven't reviewed many Land of Beds mattresses, so this own-brand is a bit of an unknown quantity when it comes to our tough support and durability tests. What we can tell you is that it's rated 'cool' to lie on, which is great news if you tend to feel hot during the night. The manufacturer markets this as a medium-firm mattress, and our independent firmness tests confirm this.
For those with a slightly bigger budget, the Otty Pure+ Hybrid Bamboo and Charcoal Premium mattress seems to throw everything but the kitchen sink under its cover to give you a good night's sleep.
This top-of-the-range hybrid contains bamboo and charcoal in its upper layers, designed to create a healthier sleeping environment. More interestingly, it's rated 'cold' to lie on, despite the hybrid combination of springs and foam. In our firmness tests, this mattress was ranked as 7.2 on a scale from one (very firm) to 10 (very soft), so it's towards the softer end of the scale.
We don't just rely on the subjective opinion of our mattress testers after lying on each mattress - we go the extra mile with our tests, so you can be sure you're picking the right mattress for your body temperature.
