Mattress 101


Mattress Anatomy

Pocketed Coils

Pocketed coils are small, strong steel coils that are individually wrapped and operate independently from one another. Higher-quality beds have a higher coil count, distributing your weight more evenly and relieving your pressure points more effectively.


Latex Foam

Latex is a dense and springy natural foam made from the sap of the rubber tree. Latex responds to the contours of your body but also offers resistance to distribute your weight evenly and relieve pressure.


Memory Foam

Memory foam is a synthetic foam that molds to the shape of your body, promoting spinal alignment and relieving pressure points while you sleep. Memory foam has a unique, "spongy" feel.



What is a Hybrid Mattress?

Hybrid mattresses combine two or more support systems, usually memory foam layers along with an innerspring system. Hybrid mattresses are a great way to experience the pressure relieving benefits of memory foam while retaining the classic feel of an innerspring mattress.

The Best of Both Worlds

Today, many sleepers are curious about the benefits of memory foam and gel memory foam mattresses, but they just can't make the jump to an all foam mattress. For these consumers, a hybrid mattress is the ideal choice. Hybrid mattresses combine an innerspring system with memory foam (or latex) to deliver the benefits of both technologies. Hybrids allow sleepers to enjoy the perfect blend of sturdy support and contouring comfort.

Familiar Support

Hybrid mattresses typically have the same size coils as innerspring mattresses, but they also use memory foam for support and contouring. The coil system enables the mattress to retain the bounciness that sleepers enjoy on innerspring mattresses, and the layers of memory foam create that unmistakable enveloping embrace. The coil system also gives hybrid mattresses a traditional mattress shape, as opposed to the straight lines and low profile of memory foam mattresses. Hybrid mattresses are often less expensive than memory foam mattresses, and they perform better than budget memory foam mattresses. The coils in a hybrid mattress will give more contouring support than the kind of foam core that's found in lower end memory foam mattresses.

Memory Foam Mattress Types

Traditional and Gel Memory Foam

Traditional Memory Foam

  • Memory foam mattresses reduce pressure points and conform to the body. Less pressure increases blood circulation for better sleep.
  • Memory foam promotes a healthier sleep environment since it is naturally anti-dust mite and anti-microbial. This is especially important for people with asthma or allergies.
  • Memory foam mattresses drastically reduce motion transfer, which is important for couples.
  • Memory foam is very durable. The majority of mattress warranties require a 1.5-inch body indentation before they are labeled as defective. Most memory foam mattresses require only a 0.5-inch indentation.

Gel Memory Foam

  • Gel memory foam is more durable than traditional memory foam.
  • Gel memory foam is even more effective at reducing pressure.
  • Gel memory foam mattresses tend to be denser, which is nice for those who prefer a lower Comfort Scale rating.


What is Visco Elastic Memory Foam?

Visco Elastic Foam, also known as Memory Foam, is a man-made substance that reacts to body temperature and weight, conforming to the shape of your body. This is the same foam originally developed by NASA to counteract the extreme forces faced by astronauts.

What are the benefits of Visco Elastic Foam?

In short, Visco Elastic Memory Foam boasts the following benefits:

  • Better contouring and pressure relief
  • Better durability and a longer comfort life
  • Better motion dampening between sleeping partners
  • More resistant to microorganisms and allergens

Visco Foam is highly resistant to bacteria, mold, mildew, mites, and other odor causing germs, making it a great option for those with sensitivities or allergies. Visco Foam is also effective at reducing motion transfer, which is invaluable for those who share a bed. If your partner is a restless sleeper, or if your partner gets in and out of bed and disturbs you during the night or in the morning, Visco Foam mattresses minimize those disturbances. Visco Elastic Foam mattresses also tend to last longer and provide more pressure relief than innerspring mattresses.

How does Visco Elastic Memory Foam work?

Visco Elastic Foam has microscopic memory pockets that react to temperature and weight. Heat and pressure cause the foam to become malleable and contour to the curves of your body, and then when the material cools it returns back to its original shape.

Are there different types of Visco Elastic Memory Foam?

Since it was invented nearly 50 years ago, there have been a number of advances in Visco Elastic Memory Foam technology. Gel Memory Foam is a combination of memory foam and gel that delivers enhanced pressure relief and adds durability to a mattress. NxG Memory Foam features an open-cell structure that allows the foam to breathe, expelling trapped heat and moisture. Many mattress manufacturers have also combined Visco Elastic Memory Foam with temperature regulating materials such as Outlast, TruTemp, and Graphene that provide enhanced cooling comfort to create the ideal sleep environment.

How does Visco Elastic Foam feel?

Visco Foam can be made in a range of comfort levels, from very dense to cloud-like soft. Visco Elastic Foam is designed to mold and contour to the curves of the body, dispersing your weight over the entire sleep surface to minimize pressure points for more comfortable sleep.

Does Visco Elastic Memory Foam vary in quality?

All reputable manufacturers produce foam products that are at least 5lb/ft³ in density. All of the memory foam mattresses, mattress pads, and pillows that you'll find at US-Mattress are of the highest quality. Beware of cheaper Visco Elastic Memory Foam beds you may find elsewhere that are below this density, as they won't contour as effectively or last as long.


What is Latex Foam?

Latex is a natural, biodegradable foam, that comes from the rubber tree predominantly found in the rain forests of South America. The material is tapped from the tree in a similar fashion as maple syrup from a maple tree. The rubber tree can then recuperate for a few weeks and be ready again to supply the natural latex to the farmers. Latex provides a good source of income for the farmers, but more importantly, the rubber trees are now seen as a renewable source of income that outweighs the value of the land to a logging operation. Every latex mattress made helps to preserve 8.5 acres of virgin rain forest!

How Does Latex Foam Feel?

Latex foam contours to your body's curves and moves with you as you move in the bed, providing continuous orthopedic support.

As Latex contours to your body, your weight is spread over the entire sleep surface. The contouring effect spreads your body weight over more of the sleeping surface and minimizes pressure points, thereby enabling a more comfortable sleep. Pressure points can create discomfort and cause you to toss and turn more frequently, so a latex mattress will help you sleep undisturbed.

Another feature of Latex foam is the open cell structure that enables the mattress to breathe. This feature allows the release of body heat and moisture, keeping the sleep surface comfortable.

What are the Benefits of Latex Foam?

Latex foam is naturally resistant to bacteria, mold, mildew, mites, and other odor causing germs; properties the rubber tree acquired through evolution in tropical rain forests. Since many people are sensitive to allergens, Latex mattresses can enable healthier nights of sleep.

Latex also reduces motion transfer between partners. When your partner moves in the night, you are not as likely to feel the movement from his or her side of the bed. Fewer disturbances from your partner's movements means that you can sleep quieter, deeper, and without interruption.

How Does Latex Foam Vary?

Natural latex is soft and not very springy. Most manufacturers do not use all natural latex for this reason.

Talalay latex is naturally derived, natural latex foam undergoes a manufacturing process that improves and enhances the capabilities to provide a superior material. During the manufacturing process, synthetic and natural latex, soaps, and rubber curing agents are mixed together in a water cooled, stainless steel mix tank to create the latex foam. Every latex product on US-Mattress is created using this high quality method.


What Is a Pocketed Spring?

Also known as wrapped coils, encased coils, encased springs, or Marshall coils, pocketed springs are designed to provide proper support while transferring very little motion. While traditional coil systems have springs that are wired together, the springs in a pocketed coil system are individually wrapped in fabric encasements and perform independently from one another. This design allows each pocketed spring to react as needed, responding quickly to movement and conforming to the contours of your body.

The Art of Staying Asleep

Just because you change positions during the night doesn't mean that your partner has to. Most sleepers move somewhere between 3 and 36 times in a single night. If you share a bed, that's a lot of potential disturbances. The coils of a traditional innerspring mattress are attached in some way, which means any motion will be felt throughout the entire mattress. That's why mattresses with encased spring systems are precisely designed to reduce motion transfer. Because the springs aren't connected, each works independently, meaning weight applied to any one spring will minimally affect the surrounding springs. That's the secret to enjoying restful, undisturbed sleep.

Why Is Undisturbed Sleep So Important?

It is recommended that most adults receive roughly 7 hours of QUALITY sleep per night. If you think lying down and setting your alarm for 8 hours later is enough, it may not be. It only takes a few disturbances to break your sleep cycle and prevent your brain and body from ever entering the deep sleep needed to fully recuperate. Minimizing these disturbances with a pocketed innerspring system is one way to greatly improve the quality of your sleep.
