Memory foam mattresses are praised for their outstanding levels of comfort and support. However, some individuals do feel that they feel hot to sleep on. Despite their benefits, memory foam mattresses are occasionally known for their heat retention issues, but there are ways to make them feel cooler without sacrificing comfort.

What is a memory foam mattress?

Memory foam mattresses are made from a type of viscoelastic polyurethane foam that is responsive to heat under touch, and memory foam also responds to the pressure of the body. Memory foam was first developed for astronauts by NASA, but its unique comfort and support qualities saw it be quickly adopted as a material in consumer products, like mattresses and pillows.

Why are memory foam mattresses so popular?

Memory foam mattresses mould to the shape of the body, meaning that the support they offer is totally personalised. For this reason, memory foam is brilliant at alleviating pressure on the body and for achieving a better night’s sleep overall. Their health benefits also extend to alleviating pain in the neck, shoulders and back as they are designed to aid better bodily alignment.

Similarly, memory foam mattresses are able to absorb any movement from a partner sleeping next to you, making them a great choice for light sleepers who are easily disturbed during the night.

Although a little more expensive than their polyurethane counterparts, memory foam mattresses are praised for their high quality and durability, making them a great long-term financial investment in your overall sleep quality.

Why do memory foam mattresses feel hot?

Memory foam mattresses can feel hot as they mould very closely to the body. With this extended coverage, it’s natural to feel hotter as heat is trapped. However, memory foam is also incredibly dense and therefore airflow is reduced in contrast to other mattress types.

In some cases, memory foam mattresses are also manufactured using certain chemicals that react to certain temperatures and conditions. As a result, the mattress softens and can, in turn, lead to greater heat retention within the material.

How can my memory foam mattress feel cooler?

There are a couple of ways to make your memory foam mattress feel cooler. The easiest solution is to source a cool-touch mattress topper, which is designed using certain materials or gels to increase airflow around the body and help you regulate your body temperature.

People often underestimate the impact of lightweight, breathable bedding too. You should opt for pure cotton where possible, not polyester or linen. Unlike manmade fabrics, cotton is good for regulating your temperature as it allows for breathability. 

Your mattress will also feel cooler depending on the surface it is situated on. If your mattress is also placed on a solid bed frame, the heat retained inside it will have reduced surface area to escape. To enable better breathability and ventilation of the mattress, you should consider investing in a slatted bed frame to increase airflow around it.

For tailored guidance on how to make your memory foam mattress feel cooler, any reputable memory foam mattress manufacturer will be happy to help.
