Have you ever wondered what a mattress is made of? Or how memory foam is made? Or the difference between a quilted mattress vs. spring mattress? As your mom always said, it’s what’s on the inside that counts.
When considering your mattress options, you may wonder what’s going on beneath the fabric that makes it feel like you’re sleeping on clouds. Below is a thorough overview of the various materials that go into making a mattress so the next time you walk into a mattress store you can tell the salesperson exactly what you’re looking for, down to the foam type! The following materials found in many different types of mattresses are some of the key ingredients to a good night’s sleep.
The Most Common Materials In All Mattresses
A soft, movement-absorbing material that helps with temperature regulation and pressure point relief. Some common types of foam include memory foam, gel memory foam, polyurethane foam, and viscoelastic foam (also known as “rebounded foam”).
Used as a filling in pillowtop mattresses and mattress covers.
Can be found in some mattresses for extra padding and temperature regulation.
A breathable material used both inside and outside of the mattress.
Used in mattresses to bond layers, materials and seams together for the perfect fit. Quilting is often used in combination with adhesives to further strengthen the bond between layers.
Found in all mattresses sold in the United States due to flammability laws for fire resistance.
Either formed as open coils or individually wrapped coils (also called pocketed coils), these are a key structural component that establish firm support at the base of the mattress.
Now that you know the most common mattress materials, let’s get more specific about what goes into the three most popular mattress types: innerspring, memory foam, and hybrid mattresses.
What is a Memory Foam Mattress made of?
These mattresses are known for lush layers of memory foam and polyurethane material which conform to your body. A newer addition to the memory foam family is gel memory foam which acts as a phase changing material (PCM).
On a spectrum from hard to soft, specialty foam layers work together to relieve pressure points from your joints and balance your body temperature. These layers conform to your body shape and absorb movement so you sleep undisturbed.
Memory Foam Mattress Cover Materials
Covers used on memory foam mattresses are typically stretch knit covers that allow you to settle comfortably into the foam. With the cover working its magic on top, higher density foams are used as the core layer of the bed to provide support. These beds do not have coils in them! This benefit is great for those who prefer to settle into the mattress with less of a bounce factor because the firmer core layer of foam helps provide a balanced support system.
What is this high-density foam core made of exactly? They are usually made of polyurethane, but can sometimes be made of more natural materials like soy-based foams or latex.
Since they don’t have coils, memory foam mattresses don’t need a foam encasement for edge support to hold the bed together. Some foam mattresses have firmer foam near the edge of the bed, but this is not necessary for support since the high-density foam offers even support throughout.
What is an Innerspring Mattress made of?
Innerspring mattresses come in two different systems: open coil or individually pocketed springs. The outer quilting is typically made of traditional cotton fabric blends that give each mattress a unique look, fitted with steel coil springs for a firm base support.
It’s important to remember that the number of coils doesn’t always amount to the same level of comfort from one mattress to the next, but plays a role in reducing motion transfer and offering support.
Each manufacturer uses different designs and support techniques to achieve this result, often including layers of polyurethane foam and filling inside the mattress. However, more luxurious innerspring mattresses will use other kinds of foam, including memory foam, gel memory foam and latex materials.
Innerspring Mattress Cover Materials
Cover materials can range from polyester to cotton or stretch knit, each one specifically designed to be soft and breathable. Fun fact: the tighter the cover, the firmer the bed will feel.
When you wake up and get ready for the day, edge support materials are important — especially if you prefer to put your shoes on while sitting at the edge of the bed! These materials range from thick metal rods to foam inserts and encasements. The more edge support you have, the more sleep (and sitting!) surface available.
What is a Hybrid Mattress made of?
Hybrid beds are among the latest and greatest options on the market for better sleep thanks to the many unique benefits hybrid mattresses offer. Specifically, they combine a 50/50 ratio of individually wrapped coils with memory foam to offer the best of both.
The coils offer support, while memory foam and gel memory foam layers conform to posture and regulate body temperature. Cotton fabric blends are added to protect the bed. You get the best of both mattress types above in the hybrid, plus personalized materials that are going to work together to help you get a good night’s sleep.
Hybrid Mattress Cover Materials
Hybrids tend to have a more elastic mattress cover so as not to interfere with the conforming benefits of the memory foam layers. Further enhancements to hybrid collections showcase foam encasements, made from high-density foam, which supports the edges of the mattress.
Knowing the basic building blocks of your mattress can help you ensure that your next bed has all your favorite ingredients for good night’s sleep.
