Is Memory Foam Affected By Temperature And Why – Best Guide

Do you know memory foam is affected by temperature and why?  The answer is memory foam is not affected by temperature. The material is made of polyurethane, which is a type of plastic.

As you may know, memory foam is a type of polyurethane foam known for its viscoelastic properties. This means that it is both elastic and viscous. This means it can return to its original shape after being deformed. Yet, this property also means that memory foam can be affected by changes in temperature.

I am recommending here; If you want to maintain optimal comfort levels while sleeping on memory foam. It’s essential to keep this quirk in mind.

Is Memory Foam Affected By Temperature And Why – General Rules

At that time, the temperature around memory foam decreases. The foam will become more rigid and less pliable. This is because the molecules in the foam slow down and become more packed together. Conversely, when the temperature increases, the memory foam will become softer. As well as more malleable as the molecules spread out and have more space to move around.

So why does this matter? Well, if you live in an area with extreme temperatures (either hot or cold). You may notice that your memory foam mattress density doesn’t feel quite the same. As it did when you first bought it. If it gets too cold, your mattress could become so firm that it’s uncomfortable to sleep on.

But, if it gets too hot, your mattress could start to sag in places and not provide the same level of support. Make sure your bedroom is at a comfortable temperature year-round. Meanwhile, your mattress always feels right!

What Is The Memory Foam Temperature Range

Memory foam mattresses are often advertised as being temperature neutral. It means they don’t get too hot or too cold. But what is the ideal temperature range for memory foam? The answer may surprise you – it’s quite broad!

Memory foam can perform well in a temperature range of 55-85 degrees Fahrenheit. That means it’s suitable for most climates, including hot and cold weather. Of course, if you’re using your memory foam mattress in an area that gets very hot or very cold. You may want to take some extra steps to ensure your comfort.

For example, in warm weather, you may want to use a cooling mattress topper or gel memory foam pillow. This helps keep yourself cool. And in cold weather, you may want to add an electric blanket or put your mattress on a heated pad. Memory foam is a versatile material that can provide comfortable sleep. No matter what the temperature is like outside.

So if you’re looking for a mattress that will keep you comfortable all year round. Memory foam is worth considering!

What Temperature Does Memory Foam Get Hard?

When memory foam is exposed to cold temperatures, it will become hard. This is because the molecules in the foam are designed to be soft and pliable at room temperature. But when they are cold, they contract and become stiffer. If you have ever put a memory foam mattress for your newborn baby, you may have noticed that it feels more complicated than usual.

This is because the colder temperature causes the foam to firm up.

What Is The Main Problem With Memory Foam?

Several main problems can be associated with memory foam. One problem is that it can keep heat, making sleeping on it uncomfortable during warm weather. Additionally, memory foam may not be as durable as other mattresses. It may show signs of wear and tear more.

Some people also find that memory foam has a strong chemical smell. At the moment first unwrapped, though this dissipates over time. Finally, memory foam mattresses can be quite expensive. Especially when compared to traditional spring mattresses.

Is Memory Foam Good In Hot Weather?

It’s no secret that memory foam can get hot in warm weather. But is it all that bad?

Look at memory foam’s pros and cons in hot weather.


01. Memory foam conforms to your body, providing support and relieving pressure points. This is especially beneficial if you suffer back pain or other joint pain.

02. Memory foam contours to your body heat. So it becomes softer and more comfortable as you sleep.

03. Memory foam mattresses are made with ventilation in mind. So they have good airflow and don’t keep heat like other mattress types.


1. Because memory foam contours to your body heat. It can feel hot during warm weather months. This can make it difficult to fall asleep and stay asleep through the night.

2. If your memory foam mattress doesn’t have good airflow, it can trap heat. After that becomes hot to sleep on. Look for a mattress with built-in vents, or create more ventilation by placing a fan near your bed. It opens a window during warmer months.
