The best mattress for hot sleepers

Your body temperature affects your sleep – whether it’s too hot, too cold, or just right.

Perhaps you’re the one tossing and turning because you’re too hot to sleep, while your lucky partner has long since drifted off.

You may have invested in top quality quilts, doonas and pillows, but did you know that the breathability and heat retaining properties of your mattress have a huge bearing on your sleep temperature? If you’re a hot sleeper, we are here to help.

Your Mattress Makes a Difference

In fact, your mattress may be the real key to how hot or cold you ultimately feel. There are a few simple things to look for in a new mattress and accessories if the temperature in bed is a problem for you:

How we sleep, coupled with the room temperature or if you share a bed can all affect our body temperature at night. Women have a lower metabolic rate than men so they produce less heat and can sometimes feel colder. Therefore, the best mattress for hot sleepers can really differ from sleeper to sleeper.

But every one of us is different, so choosing a bed to fit can be difficult. At SleepMaker, we’ve introduced a unique technology Kulkote into our mattresses that senses how you sleep, hot or cold. It is one of the best cooling mattresses for hot sleepers.

Hot or cold sleepers, rejoice, no more tossing and turning through the night. SleepMaker’s Performance Edit offers advanced temperature regulation technology. Our exclusive temperature management systems will ensure you remain at the perfect sleeping temperature throughout the night. We make sleep so you’ll wake feeling completely reinvigorated.

Choosing the Right Bedding

You may find that having a couple of wool or cotton blankets suits you better than just one thick doona. This is like layering your clothing during the day, and allows you to add or subtract a layer during the night to set your temperature at ‘just right’.

Choose natural fibres if possible for your covers: 100% cotton, bamboo, linen and wool are all good choices for hot sleepers and warm nights as they breathe and may wick moisture more effectively.

Mattress Size Matters For Heat

The size of your mattress will also make a difference if you sleep with a partner – especially if they’re a ‘hot sleeper’.

It makes sense to choose the biggest bed you can for your bedroom. Simply allow a bit of space when sleeping, and you may find you’re no longer too hot in bed.

Choose Natural Fibres For a Greater Sleep

The fabric composition of the quilting or top panel of your mattress can also make a difference to hot sleepers with their natural cooling properties. Breathable layers such as cotton, wool, silk and cashmere are ideal.

If you perspire, these fabrics may also help to wick moisture away from your body. The SleepMaker Climatex Quilt layer combines a super breathable, premium high loft fibre with Dreamfoam to both cool and provide comfort.

Consider the Thickness and Firmness of Your Mattress

The type and thickness of the comfort layers on your mattress can affect your sleeping temperature. Generally speaking, the softer your mattress, the cosier you’ll be.

This is because you’ll sink into a soft mattress more, so there’s less airflow around your body. We make a range of foams designed to help wick away heat while you are asleep & in many SleepMaker ranges we now combine them often with a unique layer of Kulkote technology.

Kulkote senses how you sleep and works with tiny microcapsules which, once you’re lying on the mattress, heat up and activate the process of absorbing heat. Find out which mattresses in our range have Kulkote.

Discover quality Australian Made mattresses that support a comfortable nights sleep. Find a retailer to feel and try Kulkote for yourself. We’re confident that it is one of the best mattresses for hot sleepers.

Finding the best hot sleeper mattress

The mattress can be a game-changer for hot sleepers, as it plays a major role in regulating body temperature throughout the night. A mattress that is too firm or too soft can cause heat to build up in the body, leading to uncomfortable sleep. The right mattress can help hot sleepers stay cool and comfortable by providing the right level of support and breathability. Cooling Technology in beds such as the KülKōte can help greater with this.

Frequently Asked Questions



Is memory foam good for hot sleepers?

Foam in general is an insulator. Memory foam is an open cell foam which is designed to conform to your body and trap in heat. Ideally, a mattress with memory foam would be recommended for cold sleepers.

What is considered a hot sleeper?

People generally run hot or cold. So, if you usually chuck off your covers in the middle of the night then you’re likely to be a hot sleeper. If you often wake up in the middle of the night feeling too hot or wake up in a sweat, then the room or your sleep climate is too hot for you and you might need a mattress for a hot sleeper. Look out for cooling technologies when shopping for a mattress and try putting the fan on when going to bed.

What is the best sleeping temperature?

You’ll have the best sleeping temperature on a mattress with Kulkote. From studies done in New Zealand’s Auckland University to test Kulkote on a SleepMaker cooling mattress. When your skin temperature reaches between 29°C and 33°C, the KülKōte technology activates. The testing found that in a simulation of someone asleep on the KülKōte mattress, the sleep surface reached 29°C and stayed at this temperature for 22 straight hours. However, on a traditional mattress without KülKōte, the sleep surface reached 35°C and stayed that way – a full six degrees hotter than the mattress using KülKōte.
