Memory Foam Buyer's Guide

Heat Retention
 

Question: I’ve Heard That Memory Foam can Be Hot… Is That True?
Short Answer: No, not if you buy modern, 2nd Generation Foam.

The most common complaint about memory foam in the past, was that it held too much heat. Memory foam is pretty dense stuff, so as a general rule, it doesn’t allow heat to dissipate the way other materials do. Early formulas for memory foam were terrible at heat distribution, and had no ventilation of any kind. As with almost everything else though, memory foam has been improved significantly in recent years. The advent of new formulas, as well as the addition of new ventilation systems keeps the new 2nd generation memory foam from holding so much heat.

Like a lot of guys, I tend to “sleep hot,” so it took some time to find a mattress that didn’t make me sweat. A lot of the “mall brands” still use an older formula for memory foam, and haven’t really addressed the ventilation issue. I would definitely recommend that you look into a mattress topper with some kind of channeling for air flow. I think the Sleep Aid people have addressed this issue most effectively. They’re the only ones with a serious ventilation system that really works.

Question: Is All Higher End Memory Foam The Same?
Short Answer: Absolutely not.

Memory foam is a process-intensive product. That means that it takes time, technology and money to produce. Be very wary of discount foam mattresses and toppers… if it seems too good to be true, it probably is. That being said, the most expensive brand isn’t necessarily the best, either.

One of the most important differences among foam companies is how they process their product. Some of the lower cost companies produce foam sheets through a pouring process. Liquid foam is poured into a large tray to cool, and, of course, gravity then acts on it.

As the foam settles, certain inconsistencies appear in the density of the product. Ironically, some of the higher priced manufacturers, like the mall brands, also use this older method of producing foam.

A much higher level of consistency is achieved with a newer production process, vacuum injection. Rather than relying on gravity, this newer process uses a vacuum chamber to keep the foam at a consistent density, eliminating variation. This allows the manufacturer to produce a consistent, reliable product. Sleep Aid gives an interesting and very clear account of this new process on their website.

Conclusion
I hope this buyer's guide will be helpful for readers trying to navigate the world of memory foam. It can be confusing, and there are a lot of things to consider, but it will be worth it when you lay down on that new memory foam mattress or topper or whatever you choose. Every day memory foam is changing lives for the better, and it could change yours too.
