If you're interested in a more in-depth explanation, read our article on the differences between coil systems. It includes the Bonnell Coil, Continous Coil, Tied Coil, and Marshall Coil (pocketed coil) systems.

Memory Foam Mattresses

memory foam mattress is one where there are no springs, the mattress is made with all foam. Mattress manufacturers have created varying types of memory foam (also known as Visco Elastic Foam) for their beds, including open-cell memory foam and gel memory foam. The memory foam mattresses available today are far superior to the ones first offered nearly 30 years ago. The best memory foam mattresses have solved many of the initial issues, such as overheating.

History of Memory Foam

The creation of memory foam goes all the way back to the 1960s. Before they could land on the moon, NASA needed to solve countless issues with space travel. One of which was the comfort level of their astronauts. NASA set out to create a material that would mold an astronaut's body to provide relief from intense G-forces. In 1966, memory foam was developed as a result of those concerns and would remain a NASA property until the 1980s.

It wasn't until 1991 that the first memory foam mattress was unveiled to the world by Tempur-Pedic. As the first company to use memory foam in mattresses, they've been a leader in the industry since. They continue to advance and improve memory foam, as do many other mattress brands. 

Some of the top memory foam beds are now created by direct-to-consumer brands like Casper and Saatva. These companies ship the mattress right to you very quickly, rolled up in a small box.

Benefits of Memory Foam Mattresses

There are many advantages to sleeping on memory foam, whether on an all-foam bed or an innerspring with memory foam comfort layers added to the top. Those who do not have memory foam can get some of the benefits by adding a memory foam mattress topper to their bed. It's also a good way to make any bed softer.


For one, it's more hypoallergenic than traditional mattress materials. The denseness of the material prevents dust mites and other allergens from building up inside, making memory foam a great option for those who suffer from allergies.

Temperature Control

Also, while there were originally problems with memory foam retaining too much heat, that story has flipped. Advancements in cooling technology have allowed mattress companies to create memory foams that do more than just prevent overheating. They can actually help keep you cooler, one of the best examples being Tempur-Pedic's Luxe Breeze line. According to Tempur-Pedic, these beds can keep you up to 8 degrees cooler throughout the night.

Pressure Relief

Memory foam is extremely conforming and uses your body heat to mold to the shape of your body. This makes memory foam excellent for pressure relief, reducing pain and restlessness. Side sleepers will especially find this beneficial, as they usually deal with some serious pressure on their shoulder and hip. Memory foam will cradle the joints gently.


Memory foam also does a surprisingly good job of supporting. Since it shapes to your body, it fills in the dips and holds you in a natural position. This helps keep your spine aligned, which is essential for avoiding back pain.

Motion Transfer Reduction

Memory foam reacts to heat rather than movement and will do a great job at reducing motion transfer between sleep partners. This is very helpful for those who sleep with someone that moves around a lot. Being disturbed throughout the night greatly impacts the quality of your sleep, so minimizing the transfer of motion is a big perk.

There are several different types of memory foam, which work differently. 

Gel Memory Foam Mattresses

Gel foam is more durable than traditional memory foam and is more effective at reducing pressure. Gel foam mattresses tend to be denser, which is nice for those who prefer a firmer comfort scale rating.

PolyFoam Mattresses

Polyfoam is petroleum-based foam, made with a variety of chemicals. To ensure safety, make sure it'sCertiPUR-US Certified. This foam can come in many different densities and softness levels. Higher-density foams will be more durable. It's a common material used to add comfort and pressure relief to mattresses.

Disadvantages of Memory Foam

While there are many advantages, there are a few downsides to memory foam. The main one is the lack of responsiveness. Some people don't mind it at all, but those used to a traditional feel may find the feeling a bit restrictive. Some types of foam are more responsive than others, like gel memory foam, but it can be a bit difficult to move around.

If you're someone who likes to change positions frequently and easily, a bed with a coil system may serve you better. That doesn't mean you have to give up the benefits of memory foam though, hybrid mattresses combine layers of memory foam with an innerspring system to achieve the benefits of both types of beds.

One other problem, which was previously mentioned, is the tendency to overheat. While this was a much bigger issue 30 years ago, some types of memory foam do retain heat. The best memory foam mattresses have solved this issue with better materials. More premium foams will have better breathability and cooling technology incorporated, so it really depends on the level of quality. You'll find heat issues come up in cheaper memory foam mattresses more frequently.

Memory foam beds can also lose their comfort life sooner than an innerspring. This comes down to the fact that coil systems are made of steel and are extremely durable. It's once again determined by the quality of the memory foam. While some memory foam beds will last as long as any innerspring, some will start showing body imprints or sag around the edges. It's important to check how long the warranty lasts and the reputation of the brand you're buying from. A 10-year warranty or more is a good indicator that a mattress is of solid quality.

How is a Memory Foam Mattress Built?

Memory Foam Mattress Layer Cut Away

All memory foam mattresses have a foam core at the bottom upon which all other layers rest. This foam layer is usually firmer than the rest of the foam to provide a stable structure for the comfort materials. On top of the foam core, different combinations of foams provide the support and body-contouring memory foam beds are known for.

There are usually at least two layers of memory foam on top of the foam core, with sometimes as many as five to seven more comfort foam layers. Where the foams are placed determines their purpose. For example, the foam at the very top is usually the softest. It's meant to provide plush comfort and to give the mattress a softer initial feel when you lay on top of it. Other layers provide cooling properties, body contouring, back support, and pressure relief.

Hybrid Mattresses

Hybrids combine an innerspring support system with layers of memory foam or latex. They're an excellent category of beds because they take the best of traditional beds and add more pressure relief with new memory foam technology. For more information, read What is a Hybrid Mattress?

Natural Mattresses

People who are environmentally conscious or concerned about their health may want a natural or organic mattress. These are typically either latex mattresses or innerspring mattresses made with natural materials like cotton and wool. Free from chemicals, they are great for anyone who wants to ensure the freshest sleep space possible.

One great option that is both natural and convenient is the Joybed. As a bed-in-a-box, it ships quickly and in a small box right to your front door. No hassle with scheduling delivery and it's easy to set up.

Adjustable Beds

For those who want the ultimate luxury, adjustable beds are the way to go. An adjustable mattress paired with an adjustable base allows you to change the angle of the head and foot of your bed. This allows you to customize your support. It's also great for those who want to do other activities in bed, or for those who have to spend a lot of time in bed.

Adjustable beds can help with many common sleep problems, such as snoring and back pain.

There are a lot of different kinds of beds that ship in a small box, but let's talk about what's unique to this type of mattress. Mattresses in a box are compressed and rolled into a small box, which can be delivered through the regular mail system. Once you receive it, you can easily carry it to wherever you plan to set up your mattress. It'll expand fully within a few hours once you take it out of the packaging.

Futon Mattresses

Futon mattresses are not as thick as traditional mattresses, and not as durable. You can find Japanese or American futons, and they are different. Japanese futons lay directly on the floor and can be rolled up for storage. The American version acts as both a bed and a couch, so it's a bit thicker. It requires a mattress and a frame.

Futon Mattress
  • Thinner than traditional mattresses
  • Two types - floor mattress or goes on a couch/bed frame

  • Not as common anymore
  • Support and comfort provided by water or air

Waterbeds and Airbeds

US-Mattress no longer carries waterbeds or air mattresses, as they aren't as popular as they used to be. Waterbeds are very heavy and difficult to move once set up. They're often not allowed by landlords, as they've crashed through floors before. However, some companies do still sell them.

Air beds, like Sleep Number, are still quite popular, as you can customize your support by increasing or decreasing the amount of air in the mattress. There are also the cheaper air mattresses, commonly used for camping, which just have one chamber. They cannot be used daily but are great for hosting guests.
