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 sheets, 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? 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 temperature in bed is a problem for you:


Temperature control

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

Layer up

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.

Get size wise

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.

Material things

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.

Cool comfort

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.
