What is a Memory Foam Mattress?

Memory foam mattresses are some of the most popular mattresses today. These beds are loved for their conforming, pressure-relieving abilities and are a go-to for many sleepers with aches and pains because they can effectively alleviate discomfort and provide better spine alignment. We’ve created five memory foam mattresses at different firmness levels to help people of all sleep needs achieve better sleep.

Memory foam, by definition, is a variation of polyurethane foam designed to respond to heat and pressure. It easily adapts to your body and bounces back to its original shape when weight is removed. Modern brands like ours have put our own twist on traditional memory foam, so our memory foam mattresses can offer even more sleep-enhancing benefits.

There are two common variations to traditional memory foam: gel-infused and plant-based. While gel infusions promote cooler sleep for a short period, we’ve found using plant-based memory foam in our mattresses delivers better breathability and responsiveness. Plant-based memory foam mattresses mitigate the two key issues with foam beds, heat retention and lack of bounce.

Our memory foam mattresses feature proprietary Bio-Pur® to relieve pain-causing pressure points and cradle your body in healthy alignment. We also include dynamic zoned support technology to offer extra support for your head, torso, and legs. This prevents sinkage and eases pain-causing pressure points in your shoulders and hips. Plus, we support each memory foam bed with our sturdy Bio-Core® base layer to resist sagging and indentations.

While memory foam mattresses are some of the best mattresses for pain relief, they’re also a good choice for anybody wanting to upgrade their night’s sleep and achieve deeper rest. Whether you’re a side, back, stomach, or combination sleeper, we offer a memory foam mattress to fit your particular needs.

Pros and Cons of Traditional Memory Foam Mattresses

  • Adapts to movement and isolates motion
  • Comfortable, contouring and pressure-relieving
  • Eases discomfort and prevents aches and pains from forming
  • Features an off-gassing odor*
  • Retains heat and causes night sweats**
  • Heavy, making it harder to move or transport when expanded

*Unlike traditional memory foam mattresses, all Amerisleep mattresses feature CertiPUR-US® certified foams that are low in VOCs and have little-to-no off-gassing.

**Our Bio-Pur® comfort layer is designed using open-cell foam which makes it more breathable and moisture-wicking than traditional memory foam mattresses so you can sleep cool and dry.

Memory Foam 101

Pros and Cons of Memory Foam

Memory foam has been in mattresses since the 90s, but its popularity has recently exploded thanks to the bed in a box mattress trend. Online mattress brands, like Amerisleep, ship their beds in a box straight to the customer’s front door. In order to fit in the box, the mattress has to be pliable and easy to compress without damaging it – making memory foam the perfect material.

A key advantage of memory foam is it’s soft and flexible. Memory foam is heat and pressure-sensitive, allowing it to conform closely and take on the shape of whatever sits on top of it. This provides excellent pressure relief without the noise and motion transfer of bouncy coils.

Of course, the benefits of memory foam go beyond its comfort. Memory foam is also perfect for shipping in a box, making it a convenient and affordable option for most mattress brands and consumers.

  • Close conforming
  • Relieves pressure points
  • Isolates motion transfer
  • No noise
  • Eases aches and pains
  • Easy to ship and set up

Memory foam is one of the most comfortable and affordable mattress materials on the market today, but it has its drawbacks too, especially if you opt for low-quality foam.

Memory foam is quite dense, causing body heat to get trapped inside. This can lead to sleepers waking up in the middle of the night sweaty and uncomfortable. So what’s the solution? Some mattress brands infuse their memory foams with cooling agents, or they add sleep technologies to increase airflow through the mattress, such as foam with cutouts in the surface. Many customers also opt for plant-based, open-cell memory foam like our Bio-Pur® layer, which is breathable, cooling, and ultra-responsive.

Lots of people love memory foam for its close-contouring ability, but for others, this can lead to a "stuck" feeling. To avoid this, choose a memory foam mattress with a stable base made of stiff foam. You can even opt for memory foam mattresses with transition layers, which are located between the soft comfort layer on top and the sturdy base foam. Transition layers help the sleeper enjoy the pressure relief of the top layer without sinking down too far and pressing against the firm base.

When you first unbox a memory foam mattress, you may notice a chemical smell. This is called off-gassing, and it usually dissipates within a few hours. If the mattress is made with plant-based oils like our beds, there may be little to no off-gassing smell at all. All the memory foam beds we produce at Amerisleep are made with CertiPUR-US® certified foams to ensure purity and safety.

  • Dense structure can trap heat
  • Sinking or “trapped” feeling
  • Off-gassing odor

Types of Memory Foam

The technical term for memory foam is viscoelastic polyurethane foam. Viscoelastic is a combination of the words “viscous” and “elastic,” and both terms describe the texture and feel of memory foam. Memory foam is elastic as evidenced by its fast responsiveness when pressed down. Lots of memory foam mattress commercials showcase this feature with a hand pushing down into the surface, and the foam immediately regaining its shape.

If something is viscous, the texture is halfway between a solid and a liquid. Memory foam conforms closely to the body while still supporting it, which is nice for sleepers who experience chronic pain, numbness, or other discomfort issues while sleeping.

Not all memory foams are created equal. Some are made with 100% petroleum-based chemicals, causing a perpetual off-gassing smell. Others contain no cooling agents to prevent heat traps. It’s good to know all your options so you choose the right one for your lifestyle and needs.

You’re probably familiar with traditional memory foam. Not only is it found in mattresses, but it’s also in car seats, medical equipment, and furniture. It could even be in the couch you’re sitting on.

Traditional memory foam is made using petroleum. Petroleum gives memory foam its responsive, soft feel. Even plant-based foams contain some petroleum, known as polyurethane. While it’s not harmful, polyurethane and other chemical fillers can cause irritation and breathing problems for some people, so look for CertiPUR-US® certified memory foam. CertiPUR-US® certified foam contains no PBDEs, ozone depleters, mercury, lead, formaldehyde, phthalates, and more.

Plant-based foam contains polyurethane, but a portion of that chemical is replaced with plant-based oils. This is done to make the foam more breathable, reduce the off-gassing smell, and increase the foam’s responsiveness – and it’s part of what makes our Bio-Pur® layer so popular among sleepers.

Cooling memory foam has been combined with an agent to absorb heat or increase air circulation through the mattress. Gel memory foam is the most popular cooling foam, but other options include foam infused with charcoal, graphite, or copper. Most of these materials are melded into the foam, but gel can be either infused or placed in the foam via gel ceramic beads.

Frequently Asked Questions

Is a memory foam mattress good for back pain?

Yes, memory foam mattresses are excellent for back pain. Memory foam can mold to the body and respond quickly to changes in position. The right memory foam mattress cradles you, easing pressure across the body that builds up into pain.

However, you want to choose the right firmness for your sleep style. If you don’t, and you end up with a too-soft or too-firm mattress, it can increase the risk of morning back pain.

Is a memory foam mattress good for side sleepers?

Yes, memory foam is a good material for side sleepers, who need a bed that cushions their shoulders and hips. If they do not receive adequate pressure relief to these sensitive areas, then their chances of sore hips and shoulders in the morning increase.

Side sleepers searching for a conforming material made without synthetic materials might want to consider a latex foam mattress, such as our Organica bed.

What's the Best Memory Foam Mattress for Me?

Choosing the right memory foam mattress really comes down to two things: reflecting on your sleep style and considering your body weight. Memory foam beds come in a whole range of firmness options, so once you find a brand you like, you can narrow down your choice based on the firmness level you need to sleep soundly.

When deciding upon firmness, first think about the way you like to sleep and the support your sleep position requires. Back and stomach sleepers need a firmer mattress with extra support under the lumbar section to keep the spine in a neutral position, whereas side sleepers need a mattress with a little more cushioning to relieve pressure under the shoulders and hips. So, if you like to sleep on your back or stomach, you’ll enjoy a medium-firm or firm mattress, and if you’re a side or combo sleeper, you’ll prefer medium and soft beds.

To further narrow down the right firmness, take into account your body type. Sleepers over 250 pounds usually want to go a little firmer than what’s recommended for their sleep style so they receive adequate lift and support. On the other hand, petite sleepers less than 130 pounds will want to choose something softer than the norm so they receive adequate comfort and pressure relief.

Once you’ve landed on your ideal firmness level, it will be easy to choose the best memory foam mattress that will deliver comfy sleep. However, if there are other features you want in a mattress, like cooling tech or plant-based foam, you’ll want to look at the specific materials and layer construction between models to determine the right match.

How is Bio-Pur® different from traditional memory foam?

Bio-Pur® is the healthier upgrade to traditional memory foam. It blends breathability, comfort, responsiveness, and support to help you get your best night’s sleep yet.

It also uses plant-based materials making it a more eco-friendly alternative to traditional memory foam.

Amerisleep mattresses are proudly made in the USA. Using the most advanced manufacturing processes, our memory foam is also certified by CertiPUR-US®. You can shop online or in-stores and get free, no contact delivery straight to your door on all orders within the continental U.S.

How long does a memory foam mattress last?

This largely depends on the foam density and construction, but the average lifespan for a good quality memory foam mattress is 7-8 years. On the other hand, Amerisleep memory foam mattresses are guaranteed to last with our 20-year warranty covering manufacturing defects and sagging over ¾ of an inch.

What happens if you sleep on a memory foam mattress before 24 hours?

Nothing should happen if you sleep on your mattress before 24 hours, as it’s built to withstand years of wear and tear. The worst you can expect is that your mattress won’t be as comfortable as it would be after fully expanding.

How long does it take for a memory foam mattress to inflate?

Most memory foam mattresses finish expanding within 24 to 72 hours—higher quality foams tend to expand faster. If your mattress has not reached its full shape within a week, it’s likely defective and you should contact customer service.

Can you fix a sagging memory foam mattress?

Once your memory foam mattress begins to sag, there’s no real way to fix it. You can buy mattress toppers to extend the life of your bed a little bit, but these will eventually begin to sag in the same spots your mattress is sagging. If your mattress has sags or visible indentations, it’s time for a new bed.

How can you keep cool on a memory foam mattress?

Many modern memory foam mattresses are built with cooling technologies to prevent heat retention and promote more comfortable sleep. You can also help yourself sleep cooler by buying breathable bedding, such as cotton or Tencel® sheets, and pairing your mattress with a slatted foundation. Slatted foundations allow heat to escape out of the bottom of the mattress, further preventing night sweats.

How thick should my memory foam mattress be?

Memory foam mattresses should be at least 10 inches thick. Mattresses thinner than 10 inches are more likely to break down and show signs of sagging sooner. Plus, ultra-thin mattresses tend to feel quite firm, so they’re not a great option for side sleepers and those who prefer a little cushion from their bed.

How do you clean a memory foam mattress?

Washing your bedding frequently prevents dust mites and allergens from accumulating on the surface of your mattress, as does regular vacuuming. To freshen up your mattress you can sprinkle baking soda on top and leave it for a few hours before vacuuming it up—some people sprinkle it on before leaving for work and vacuum it up once they get home.

Can you compress and pack a memory foam mattress?

No, as you may damage the foam by compressing it at home. Mattress companies have specialized machines to compress and pack a mattress without damaging it. Attempting to re-compress your mattress at home can damage the foam layers and structural integrity of the bed.

Do memory foam mattresses work with adjustable bed frames?

Yes, memory foam mattresses work well with adjustable bases as they’re flexible enough to move with the base. Spring mattresses may not work as well as an all-foam mattress—the motor of an adjustable base can strain itself trying to move a firm innerspring mattress.
