We’ve all seen and heard about the benefits of this miracle product and want to try it for a good night’s sleep. But like many things in life not all memory foams are created equal.

Here at The Foam Shop, we’ve taken customer education seriously since 1974 and want to help clear the air on the differences between high-quality and lower-quality memory foam to help you make informed decisions.


The Foam Shop Facts

The technical name for a true memory foam is visco-elastic foam. While that sounds important, it’s not as important as knowing that there are two basic types:

Temperature sensitive memory foam – this type of foam springs back to shape slowly once it’s compressed and is the true memory foam. While this type of foam comes in models from firm to soft, the key is its sensitivity to temperature. Simply put, these foams adapt their firmness based on body heat, allowing them to cradle you, providing that wonderful feeling that you’re “floating” on top of the mattress as it supports your weight evenly and reduces potential pressure points.

Air flow restricted memory foam – this type of foam is also designed to slowly bounce back to compression but in this case it’s through a different method – restricting air flow in the foam’s cell structure. The result is a foam that struggles to bounce back or adapt to your pressure points once it’s been compressed, resulting in a less comfortable, less restful sleep.  It also produces a hotter sleep, since air has trouble moving through the product to expel the extra warmth.


Memory Foam Fiction

A squeeze tells the whole story

It can be difficult for the average consumer to tell the difference between the cheaper-to-manufacture air flow restricted foam and temperature sensitive foam simply by squeezing it. That’s why it’s important to ask questions about any memory foam product you’re considering buying, and check the product specifications on the box.

The heavier memory foam, the better the quality

While foam density can definitely have a bearing on the quality of the product, it’s important to know where this weight comes from. In some cases, foam manufacturers add clay particles to their memory foam, increasing its density but again reducing the air flow of the mattress. Not only does the foam cell structure of this “loaded” foam break down more quickly, it also makes for a less comfortable sleep because of the restricted air flow.

All memory foam is treated equally before you buy it

One of the challenges of producing any type of memory foam products is that they’re bulky and expensive to ship. In an effort to reduce these delivery costs, some manufacturers now compress their memory foam before shipping it to the store or customer.

These reduced costs come at a price: foam performance and your comfort. Memory foam isn’t meant to remain compressed for months at a time, as this damages the cell structure of the foam causing the product to lose its ability to bounce back.

Despite test results showing foam that’s been compressed for long periods of time will lose up to 70% of their ability to perform, some products are in a compressed state for six months or more from the time they’re produced until they’re sold. Although we recommend never compressing foam to ship it, if you have to, it should never stay squeezed for more than 48 hours.
