The Truth About Memory foam Mattresses

The Truth About Memory foam Mattresses

Question. Do all memory foam mattresses sleep hot? The short answer is no, or maybe better, not really.

Memory foam tends to get a bad rap because some memory foams do retain body heat. Like any mattress you're sleeping on, it's really important to make sure that it keeps you in correct sleeping posture, (i.e. good support). If memory foam is to be supportive, it also needs to be dense. In other words, memory foam doesn't let as much air pass through unlike some other types of mattresses. It should come as no surprise then that the more dense a mattress is, the more likely it will not let the heat escape.

Memory foam can also retain heat for other reasons as well. For instance, many people like sleeping on memory foam mattresses because they contour to your body and bring relief to sensitive pressure points. Because of this, memory foam feeds off of your body heat to get the contouring effect.

The more of your body that is "hugged" by the mattress, the more likely it is that your body will hold the heat. Although due to new fabric cooling technologies, this could become a thing of the past. 

A couple of recommendations if you're currently sleeping on a mattress that holds heat. 

  • Keep the temperature in your bedroom around 65-70 degrees. Everyone is different so find the sweet spot temperature that works for you. By keeping the room cooler, it can bring a nice balance to a hot mattress.
  • Try putting a cooling mattress protector on your bed. The cooling effect from the protector can come through to make some of the heat dissipate.
