What started as a substance developed by NASA has become the go-to material for comfortable mattresses. Memory foam, or viscoelastic, conforms to your body's shape when you lie down.

The memory foam's contouring protects your pressure points, no matter which sleeping position you favor. Best of all, the mattress firms back up to its usual shape a few seconds after you get up.

Here are the best memory foam mattresses for 2021:

Read on for our list of the top memory foam beds for every need.

What Is the Best Thickness for a Memory Foam Mattress?
The best memory foam thickness depends on personal preference. The thicker the mattress, the softer it will feel. If you want a combination of cushioning comfort with firm support, an 8-inch mattress may suffice. If you prefer that completely enveloped feeling, you may opt for a 10- or 12-inch thickness.

Best Memory Foam Mattress for Side Sleepers: Leesa

A memory foam mattress is perfect for side sleepers. The Leesa Mattress offers medium firmness and evenly distributed weight. It is made with three layers of foam, including high-density foam.

The Leesa features:

  • Spinal alignment and body balance perfect for side sleepers

  • Microcell structure foam that allows for breathability, keeping your temperature down at night

  • Pressure relief on your shoulders and hips when sleeping on your side

  • No motion transfer to make it easier to sleep without disturbance

  • Just the right level of firmness to suit even combination sleepers

Leesa offers free shipping throughout the United States. They also have stores throughout the country to test out the beds in person. They offer a 100-night trial period and free shipping.

Is Memory Foam or Gel Foam Better?
Memory foam or gel-infused memory foam both offer a comforting sleep. If you sleep hot or don't like to feel "stuck" in your mattress, you may prefer gel-infused foam. This material has a bit more spring to it and stays cooler.

Best Memory Foam Mattress for Stomach Sleepers: Brooklyn Bedding

Stomach sleepers need a firm surface to keep their hips and shoulders from sinking. Otherwise, they may suffer spinal misalignment and back pain.

The Plank by Brooklyn Bedding offers two firmness levels in one mattress: firm and extra firm. But it still provides the comfort of memory foam.

The Plank offers:

  • One-inch layer of gel memory foam to keep you cool while you sleep

  • Two-inch layer of firm foam to provide compression support without sinking into the mattress

  • 7 inches of high-density foam as a stable and firm base for stomach sleepers

  • An optional cooling panel for both sides of the mattress to enhance temperature regulation

  • Foam construction to reduce noise while moving on the bed as well as any motion transfer

The Plank mattress comes with a 120-night trial period, a 10-year warranty, and free shipping throughout the United States.

Best Memory Foam Mattress for Back Sleepers: Nest Alexander Signature Hybrid

Back sleepers need the firmest support in order to keep the spine aligned. If you want the comfort of memory foam but the stability of an innerspring mattress, the Nest Alexander Signature Hybrid offers the best of both worlds.

This mattress offers:

  • Eight inches of pocketed coils for stable support of your back

  • A one-inch layer of three-pound support foam with a built-in airflow system

  • A three-inch layer of 3.5-pound temperature-controlled foam

  • A top layer of 4-pound gel memory foam for even more temperature control

  • A medium level of firmness with the comfort of contouring memory foam

The Alexander Signature mattress is CertiPUR-US-certified. You can view Nest mattresses in their showrooms throughout the United States or order the mattress online.

They offer a 100-night trial. If you don't love it, Nest professionals will work with you to find another option. Nest also offers a lifetime warranty on its mattresses.

Memory foam mattresses last about as long as an innerspring mattress—8 to 10 years. The exact lifespan depends on how well you care for it. Regularly cleaning and rotating your mattress can extend its life.

Best Memory Foam Mattress for Heavy Side Sleepers: WinkBed Plus

Heavy side sleepers need both body contouring and strong support. The WinkBed Plus has cushioning that protects your pressure points, while the base support keeps your spine aligned.

Here are some other perks:

  • Individually wrapped coils with targeted support zones to protect your back

  • Superior edge support for more sleeping space and protection

  • Gel-infused foam to keep your body cool by wicking away the heat

  • A cooling Tencel cover made from eucalyptus for soft comfort and a lower temperature

  • Medium firmness offering side sleepers support without feeling too rigid

WinkBed offers free shipping throughout the United States and a 120-night trial period. The mattresses also have a lifetime warranty.

Best Memory Foam Mattress for Hot Sleepers: Casper

Many memory foam mattresses get too hot from a lack of air circulation. The Casper Mattress gives you contouring memory foam while staying cool. You can expect the following benefits:

  • Open-cell foam structure for maximum breathability

  • Pressure-relieving foam to give your joints a break

  • Zoned support to provide pressure relief to your back, shoulders, and hips

  • Individual coils to maximize breathability

  • CertiPUR-US foams, which means fewer chemicals and off-gassing

Casper offers a 100-night trial period with a full money-back guarantee. They offer free shipping and returns and a 10-year limited warranty.

Do You Need a Box Spring With a Memory Foam Mattress
You don't necessarily need a box spring for a memory foam mattress. But some type of base is required for stability. If you have a metal bed frame, then you need a box spring. If you have a platform or wooden slat bed, then you can skip it.

Other Memory Foam Mattresses to Consider

Best for Combination Sleepers: Layla
The Layla mattress suits any type of sleeper. It offers a soft, but supportive, surface with copper-gel particles. The particles keep the mattress cool, but also provide push-back resistance in the areas you need it most. The most unique aspect? You can adjust the firmness by flipping it—one side is soft and the other firm.

Best Memory Foam Mattress for Back Pain: Amerisleep AS2
The Amerisleep AS2 mattress contains transition foam that creates comfort zones for your back. The plant-based foam keeps its shape, reducing the sagging that causes back pain. Its open-cell structure keeps the mattress cool, and the medium firmness provides the support your back needs.

Best Memory Foam Mattress for Under $500: Zinus Pressure Relief Memory Foam Cloud
The Zinus Pressure Relief Memory Foam Cloud mattress has plush memory foam, a microfiber top, and a variety of thickness options. Viscoelastic foam provides the cushioning comfort you expect out of a memory foam mattress.

What to Look for in a Memory Foam Mattress

You'll have several decisions to make before choosing a memory foam bed. Read on for everything you need to know.

Types of Memory Foam

  • Traditional
    This memory foam contours your body, helping to increase circulation and reduce stress on your pressure points. Traditional memory foam does retain heat, though. It can be trouble for hot sleepers.

  • Open-Cell Memory Foam
    Open-cell memory foam doesn't sink in quite as much as traditional memory foam. But it has better airflow, which helps keep you cooler while you sleep.

  • Gel Memory Foam
    If you are a hot sleeper, try this combination of gel and memory foam. The gel allows for more airflow than other memory foam options, which can keep you cooler.

Other Considerations

  • Foam Density
    The heavier the foam per square foot, the more durable the mattress. Some memory foam mattresses only have heavier foam in the first layer, not disbursed throughout. High-density foam should be 5 lbs per square foot, at a minimum.

  • ILD Rating
    The Indentation Load Deflection measures the material's resistance. A low ILD provides a soft memory foam surface. A high ILD provides more resistance, which provides back and pressure point support. At least one layer of a memory foam mattress should have an ILD of 20 or more.

  • Top Layer Materials
    Memory foam on its own gets hot. Many mattresses come with additional top layers that include cooling technology. If you sleep hot, this is crucial.

  • Hypoallergenic or Antimicrobial Materials
    Dust mites, germs, and chemicals can lurk in your mattress. Know the mattress' materials and look for mattresses that are CertiPUR-US-certified.

Bottom Line

Before you buy a memory foam mattress, know what it's made of. Hot sleepers, stomach sleepers, and back sleepers may need a combination bed rather than straight memory foam.

Always choose a mattress with a generous trial period to allow enough time for you to make a decision.
