How are Amerisleep memory foam mattresses designed to upgrade your sleep?

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.

Frequently Asked Questions

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.
