Comfortable Sleeping Temperature
Some mattresses have a tendency to retain body heat which can cause a hot sleep environment. Pay particular attention to foams and memory foams, and pay attention to any temperature regulating features included in a mattress you are looking at.
Sleeping Too Hot?
Maintaining a neutral temperature throughout the night is a vital component to deep sleep. The temperature of your bedroom matters, but so does your mattress.
After comfort and support, a mattress' heat retention is probably the most important aspect to consider when shopping for a new model. Mattresses perform differently in this regard depending on the materials they are made from.
Memory Foam and Alternatives
Heat retention was never a huge issue with innerspring mattresses. The innerspring structure generally has plenty of open space to allow airflow to dissipate body heat. The only real factor with innerspring mattresses is the quilt, and any reputable company will use a breathable quilt that won't cause issues.
Heat retention became important when memory foam technology revolutionized the industry. The dense nature of memory foam means the material may not be breathable, may not wick away moisture, may absorb and retain body heat, and may trap body heat rather than dissipating it. These factors can lead to hot, sweaty, restless sleep.
These issues were not well addressed during the early generations of memory foam mattresses, but since then, companies have become aware of this issue and made great strides to combat it. Gel-infused memory foam, temperature regulating quilts, and open-cell memory foam are just a few of the technologies used to combat heat retention in memory foam.
Still, memory foam tends to retain more heat than innerspring mattresses, with perhaps a few exceptions. Other alternatives to memory foam and innerspring mattresses are latex. Latex shares many of the benefits of memory foam, but can be made from natural material and tends to feel cooler than memory foam. Latex tends to conduct and dissipate body heat better, and can also be infused with gel to enhance its cooling properties.
All in all, heat retention is something you should be aware of when shopping for a new mattress. Look for cooling comfort layers, the primary support material used, and reviews that mention if a mattress sleeps hot. We have selected some good example below of mattresses that don't suffer from heat retention issues, and you can use these as a good reference when comparing other models.
