What is Memory Foam?

The formal name for memory foam is viscoelastic polyurethane foam, which describes how this material is designed. Memory foam needs to strike a balance between viscosity and elasticity.

  • The viscosity prevents the foam from changing shape under pressure, which is why you can lie on a memory foam mattress without sinking into it.
  • The elasticity allows the foam to change shape but return to its original form once pressure is alleviated. This is how the memory form contorts to your body and then bounces back once you get up from the bed.

Viscosity and elasticity work together to strike a delicate balance of comfort and support; the foam conforms to your body while still offering structure. However, not all memory foam is made the same, and brands have their own “formulas” to create unique sleeping experiences.

Is Memory Foam Toxic?

Overall, memory foam is a safe material. It would not be allowed on the consumer market if it wasn’t. However, there are some things to look out for when buying a memory foam mattress.

When you first unbox your mattress, it might release a plastic scent that is unpleasant to be around. This is known as off-gassing and occurs when the volatile organic compounds (VOCs) are released. If you are sensitive to VOCs, run an air filter in the room with your new mattress and wear a mask until it is fully aired out.

Additionally, memory foam can trigger some asthma and allergy attacks or provoke respiratory issues for some people. This has to do with the components used to make the mattress. Try to spend time around memory foam mattresses before you buy one to see how they affect you.

Pro Tip:

For the best quality memory foam, look for mattresses with CertiPUR-US certifications.

Memory Foam vs. Gel Memory Foam

One of the most popular developments in recent years is gel memory foam material. Manufacturers start with a standard memory foam design and then add gel elements that cool the customer who buys the mattress. Gel foam is ideal for hot sleepers who often toss and turn throughout the night.

Understanding gel memory foam is important if you are trying to learn what are mattresses made of. Gel is just one way that mattress developers keep sleepers cool. Depending on the brand, select gel memory foam mattresses use special structures with air pockets that circulate body heat away from you so it doesn’t build up over time. If you aren’t sure about sleeping on gel memory foam, there are alternative cooling options to invest in (keep reading to find out!).   

Is All Memory Foam the Same?

There are multiple types of memory foam, each made of different materials and components. While the variety is nice, it also means answering “What is gel memory foam made of?” is usually a case-by-case scenario. However, most manufacturers have similar formulas—here are a few materials used in memory foam mattress construction and why they are popular with customers.

Type of Memory Foam Good to Know
Graphite Memory Foam These mattresses tend to be more durable because added graphite in the memory foam, but they’re also recommended for sleepers looking for a bed with breathability. The enhancement usually comes with a price markup, but if you have the budget, this is a great upgrade to basic memory foam.
Bamboo Memory Foam This is a newer variation on memory foam, thanks to consumers requesting more holistic sleep solutions. With these beds, bamboo particles help absorb odor and moisture for a cleaner sleeping experience. Aside from being more sustainable, some sleepers also claim sleeping on plant-based memory foam comes with the added perk of better responsiveness versus regular memory foam.
Copper Memory Foam Along with other metals like aluminum, copper fibers in memory foam are used to regulate the temperature of sleepers. They also offer antibacterial properties, which can help reduce or prevent mold and mildew buildup.
Charcoal Memory Foam Similar to bamboo memory foam, this memory foam variation has significant odor-absorbing properties. Charcoal is also great at absorbing heat.
