Overheating in bed is no joke – it can really cut into those forty winks and leave you feeling worn out the next day. Thankfully, there are some great options specifically geared towards hot sleepers who need extra temperature regulation.
Join us to discover the best mattresses for hot sleepers:
Wool just has this unique ability to regulate your body temperature. The crimped fibres create tons of ventilation space so air can flow freely. This keeps hot sleepers from getting that sticky, humid feeling from moisture buildup.
Here are some great options:
- Sleepeezee Wool Supreme 2400 Pocket Spring Mattress
- Sleepeezee Wool Deluxe 1200 Pocket Spring Mattress
- Giltedge Beds Wool Luxury 1500 Pocket Spring Mattress
Unlike synthetic fabrics that trap heat, wool whisks sweat away from your body. The material adapts well during the night when your body temperature goes up or down, preventing you from getting those dreaded hot flashes when you overheat.
Wool also has an inherently buoyant, cushiony feel. You’ll rest lightly nestled in the mattress rather than sinking deep like with memory foam.

Memory Gel Mattresses
Memory gel is memory foam with gel within it. There are two main types of cooling gels you’ll find in memory foam mattresses for hot sleepers:
- Thermal gel – tiny beads of gel that feel cool to the touch. It absorbs and dissipates excess warmth from contact with your body.
- Phase Change Material (PCM) is an encapsulated gel that stays solid at average room temperature but becomes liquid when heated by your body heat.
Infusing these nano-sized gels gives memory foam better conduction and airflow inside the material, preventing the foam from retaining as much ambient heat from your body as traditional varieties would.
You get the contouring pressure relief of memory foam with more advanced thermal regulation – ideal for those susceptible to overheating at night. Just be sure to choose a model with sufficient foam density and support layers underneath.
Graphite-Infused Memory Foam
Mixing graphite powder into memory foam leverages graphite’s excellent thermal conductivity. It pulls heat away from your body as you sleep and flows it across the mattress’s surface. The Sleepeezee G4 and G3 fit the bill.

Graphite’s porous structure and carbon content make it superior at dissipating heat energy evenly and quickly. Graphite regulates the overall sleep environment, unlike cooling gels that respond to you individually. Anyone sharing the bed can enjoy the cooler sleep surface, not just the hot sleeper. And there’s no discernible difference in feel to standard memory foam.
For best results, look for a density graphite infusion between 10% and 40% – the higher the graphite content, the more breathable the foam.
Vented Air Borders
A neat but underrated design feature on some mattresses is a ventilated side border around the mattress perimeter. At the edges, it looks like a hollow channel.
The vented border serves as an air intake and outtake, cycling fresh air under the comfort layers. As you shift positions at night, warm air from your body heat gets vented out while cool air gets sucked back in.
Mattresses with vented borders promote steady airflow to whisk away humidity and heat. The ventilated channel surrounds all four sides, so your sleep direction doesn’t matter.
Summer/Winter Side Mattresses
Look for winter/summer side mattresses where one side of the mattress focuses on cooling properties for hot summertime nights using phase change gels, graphite or copper infusion, and moisture-wicking covers.
The winter side contains foams and materials selected for better heat retention and insulation during cold weather, such as wool, fibre batting, or dense side panels that trap warmth close to the body.
With the change of seasons, rotate your mattress to have the appropriate temperature regulation year-round—no need for bulky mattress toppers or excessive blankets to layer on.
Dual-sided mattresses tend to be pricier but deliver versatility and customisation that other mattresses can lack. And you maximise the lifespan of sleeping on alternating surfaces.
