How to Make Memory Foam
First, does memory foam sleep hot? Is there a need to try and make memory foam sleep cool?
I'm constantly amazed at how much attention the issue of sleeping hot on visco-elastic foam is brought up in initial conversations about sleeping on it.
First off, I think the topic is borne out of people's experiences with foam mattresses prior to the invention of NASA foam.
I remember in the 60s (yes, I'm old! LOL), I used to have a "camping mattress" that we put into our pickup camper to make it more comfortable.
I was actually comfortable when you initially laid down on it, but soon you were sweating everywhere your body came in contact with it.
This is caused by the closed cells of the foam not allowing any air to move between your body and the foam. It was trapped.
The biggest difference in memory foam is that it's an open-celled foam—which means the air can move around and cool you.
I've only spoken to one or two people who slept on a foam mattress that thought it slept hot and that's out of hundreds of people—maybe a thousand.
If you're worried about this problem, you can take a couple of steps to help you sleep cooler.
First, you can order a waterproof mattress protector that will allow even more air to pass between you and the memory foam mattress or topper so you don't have to worry about the heat problem.
Another help is to put satin sheets on the bed which tend to sleep cooler as well.
This is the best way I know how to make memory foam sleep cool.
