  • Doing their part to be environmentally conscious and reduce waste, each mattress cover is made with up to 121 recycled bottles.

Best Memory Foam Mattress for Pressure Relief

Nolah Signature


  • Foam Mattress
  • Best for Side Sleepers
  • Firmness Level: 4/10
  • 120-Night Trial
  • Lifetime Warranty

Memory foam is superior when it comes to pressure relief, but Nolah takes it up a notch with their proprietary take on the material. The Nolah Signature uses the brand’s Cooling Nolah AirFoam™, which provides the contouring of memory foam but is also made to keep cool.

The Nolah Signature’s 12-inch profile also features a second layer of AirFoam™ further below for added pressure relief, making this an exceptional fit for people who need both pressure relief and cooling. Because the Nolah Signature has quality pressure-relieving capabilities and a softer feel, we think this bed is best suited for side sleepers, who are often the group who need pressure relief the most.

Why we picked it

The Signature’s all-foam design should work well for people who share a bed with a partner, reducing motion transfer so that one person is less likely to disturb the other.

Best Luxury Memory Foam Mattress



  • Memory Foam Mattress
  • Best for Side, Back, and Stomach Sleepers
  • Firmness Level: 5/10 (Soft), 8/10 (Firm)
  • 90-Day Trial
  • 10-Year Warranty

  • Memory Foam Mattress
  • Best for Back, Stomach, and Combo Sleepers
  • Firmness Level: 6/10
  • 100-Night Trial
  • 10-Year Warranty

The Cocoon Chill is 10 inches tall, featuring three foam layers to support sleepers in all sleeping positions. The construction begins with a stretch-knit cover and a 2-inch layer of Cocoon’s Perfect Fit Memory Foam. Next is the 2-inch Responsive Comfort Layer, followed by the 6-inch Essential Support Layer. All foam layers work together to prevent pressure build-up in the legs, shoulders, and hips.

Why we like it:

  • The Cocoon Chill mattress should be good for hot sleepers thanks to its phase-change technology. The technology prevents the foam layers from overheating, drawing the heat away from your body to allow you to cool.

Best Memory Foam Mattress for the Money

Dreamfoam Chill


  • Memory Foam Mattress
  • Best for Back, Side, and Stomach Sleepers
  • Firmness Level: 5-6/10 (Medium), 6.5/10 (Medium-Firm), 8/10 (Firm)

The height of the mattress determines the height of the layers. All models feature dense polyfoam and gel memory foam to adapt to the body and cushion the typical pressure points. The gel cools hot sleepers, pulling the heat away from the body and preventing overheating. The 14-inch and 12-inch Dreamfoam Chill mattresses offer more support thanks to the VariFlex™ transition foam layer.

Why it stands out:

  • Each foam layer of the Dreamfoam Chill features the open-cell technology for enhanced breathability and airflow.

Why Memory Foam? Are They Good?

A Brief History

Memory Foam is typically polyurethane combined with other chemicals. Those additional chemicals add to the viscosity and density of the end product.

You may also see it referred to as viscoelastic polyurethane foam. The origins of this material can be traced back to 1966 when NASA developed it.

Find Out More: What Is Memory foam?

Memory foam was released to the public domain in the 1980s, and it has gradually gained popularity since then. Today, it’s used in many home products, including mattresses.

Get More Info: How Memory Foam Works

What Does Memory Foam Feel Like?

Many users of memory foam report that it has a unique and recognizable feel. It hugs and contours your body as you compress the mattress, providing exceptional pressure relief and support, and it is particularly helpful for those struggling with aches and pains.

The material will gradually change shape to match the outline of your body, meaning the mattress is essentially customized for your needs each time you lay down. When you get up, the material will regain its original shape, readying itself for the next use.

Illustration of a Woman Sleeping on Her Side on a Soft Mattress

Another advantageous feature of memory foam is the motion isolation it offers. Motion isolation means there is very little transfer of movement from one side of the mattress to the other. If your partner is tossing and turning in the night, for instance, you are unlikely to feel it as you sleep.

Motion isolation is not a feature that can be claimed by a traditional spring mattress, which is one reason why memory foam has become so popular. Viscoelastic properties are what make this foam unique, and it’s worth noting that poly foam without viscoelastic properties is not memory foam.

What to Look for in a Memory Foam Mattress

Once you’re ready to start shopping, you’ll need to know what to look for in a memory foam mattress. Some factors are focused on your current status, such as how you sleep or budget limitations, while others are more preference-based. Taking into account these specific details is important for purchasing a new bed that meets your standards and helps you sleep better.

Budget & Pricing

Your budget and mattress pricing will likely be at the top of your list when narrowing down options. Memory foam mattresses typically cost more than traditional innerspring mattresses because of the foam’s durability, pressure-relieving properties, motion isolating capabilities, and strict manufacturing standards. Some brands may enhance their memory foam by incorporating special cooling features or plant-based materials, which could increase costs as well. Even though memory foam beds may be higher in price, the material’s high-end quality is worth the investment. 

Sleeping Position

Your sleeping position will influence the type of mattress you should buy. The four sleep styles are side, back, stomach, and combination. Certain types of beds are better for some positions more than others, including memory foam. So, while you may like memory foam, you need to be sure it complements how you sleep. 

Side Sleepers

Side sleepers should benefit most from memory foam. Lying on your side can create pressure buildup, particularly in the hips and shoulders. Memory foam does an exceptional job of providing pressure relief, making it fantastic for side sleepers. In general, side sleepers should stick with plush to medium-firm beds to obtain adequate pressure relief in this position.

Back Sleepers

Back sleepers are a good fit for memory foam, which can relieve pressure in the shoulders. People who rest on their back often need beds that are strike a balance between firm support and soft pressure relief. These sleepers should consider memory foam beds that have a medium-firm feel. 

Stomach Sleepers

Stomach sleepers will match best with firm memory foam beds. Memory foam contours the sleeper’s shape, but if the material is too soft, the deeper cradle could throw off spinal alignment. Memory foam can provide a light, initial cushion for the hips, but the focus should be on firm support layers to keep the midsection from dipping too much. 

Combination Sleepers

Combination sleepers are least likely to benefit from memory foam because the material is not highly responsive. Instead, memory foam provides a slow-moving feel as it cradles the sleeper’s shape. Combination sleepers do best with beds that have a quick response, such as latex or innerspring models, because these materials make it easier for people to reposition. If you have your heart set on memory foam, a hybrid mattress, which also contains springs, should provide more bounce.

Body Weight

Your body weight will affect how a bed feels and performs because the heavier you are, the deeper you will sink into the layers. A mattress’ firmness rating is a helpful indicator for determining the right product for your shape. Plus, some brands offer mattresses catered to specific body types.

Lightweight Sleepers

Lightweight sleepers are those weighing 130 pounds or less. These individuals fit well with plush to medium beds. Lightweight sleepers don’t sink into the mattress as much, so they need a softer bed to compensate for this. Plush mattresses will help these sleepers avoid feeling like they’re lying on a rock. Sleep position will also need to be considered. If you’re a lightweight side sleeper, you should get a soft mattress, but back or stomach sleepers should get a medium mattress.

Average Weight Sleepers

Average weight sleepers are between 130 and 230 pounds and make up the majority of shoppers. These individuals carry more weight than petite sleepers and need a slightly firmer feel to ensure their body remains in alignment. The best beds for this group have a medium-firm or firm feel, depending on their sleep position. 

Heavy Sleepers

Heavy sleepers are considered those weighing over 230 pounds. People with significantly larger frames have a higher risk of sinking too far into the mattress, which can feel uncomfortable and throw off body alignment. These shoppers should either purchase a firm mattress or a bed specially designed for plus-size sleepers.

Cooling is a valuable feature for those who easily overheat at night. A mattress with temperature-regulating capabilities will help hot sleepers stay cool, increasing their chances of a good night’s rest. A common complaint of memory foam is that it retains heat, but many manufacturers offset this by infusing cooling features into the foam. Gel is a popular memory foam cooling mechanism, but some brands have also used copper or an open cell design. If you sleep hot, look for memory foam beds with cooling properties.

Heat Retention Levels

Heat Retention Graphic – How cool or hot each type of mattress sleeps.


The firmness is typically connected to the weight of the bed. Heavier mattresses are going to be firmer and more supportive on the whole, while lighter versions will usually be softer. There will be some variation in firmness from model to model when comparing weights, so check the firmness rating of any mattress before making a purchase.

Firmness is formally measured on a scale known as ILD (indentation load deflection). On this scale, a higher number, like 12 or 13, is firmer than an 8 or 9.

We use a scale of 1-10 (ten being the most firm) with the products we review, and these firmness ratings are based on how the bed feels as you lie on it.

Firmness Scale 1-10


Mattress thickness is something to consider as you shop. This includes the thickness of the individual layers and the total profile. Construction varies among brands; Some beds are 14 or 15 inches thick, while others have a 6-inch profile. Shoppers will need to take into account the height of the bedframe and the sleeper’s physical makeup. For example, a 15-inch mattress could be too high for young kids and elderly individuals, and a 6-inch bed may not give enough pressure relief. As a general guideline, roughly 4 inches in the comfort layers should be good, but it can be split into two comfort layers.

Foam Thickness Example

Many couples enjoy memory foam mattresses because they isolate motion well, reducing the chance of one partner waking up the other if they move. However, memory foam has minimal bounce, which some sexually-active may view as a drawback. Other important factors for couples will be edge support performance, cooling, and a versatile firmness that works well for both individuals.

Motion Isolation

Motion isolation refers to the bed’s ability to limit the transfer of movement across the mattress. This capability is usually most beneficial for people who share a bed and want to avoid disturbing their partner if they toss and turn or have different schedules. Memory foam excels is isolating motion, so if this feature is important to you, these beds are a great match.

Edge Support

Edge support is something to consider if you want extra surface space use. Mattress edge support means that the bed’s perimeter offers equal support, so you don’t dip much if you lie or sit along the sides. Many mattress brands provide edge support through reinforced materials like strong foam rails. If you share a bed or usually sit on the edge to put on clothes or shoes, look for brands with proven edge support. 

Lifespan & Durability

The bed’s durability and expected lifespan will have a lot to do with the quality of the product you purchase. Spending more money on a high-end mattress could return you a better product, which can be expected to hold up for a longer period. Additionally, maintenance of the mattress will determine how long it lasts. In general terms, you should expect seven to ten years of quality performance from a memory foam bed.


Off-gassing is the initial smell a new mattress may have. Off-gassing is generally harmless but could be bothersome for those who are sensitive to smells. Memory foam is a synthetic material, so some off-gassing can be expected. These fumes typically dissipate after a few days, but if you’re easily bothered by smells, you may prefer a more organic bed. 


Response means how quickly a material recovers when compressed. Memory Foam has a very slow recovery rate and takes a few seconds to return to its original shape. This means the material will contour your body better, but some people may consider the slower response a downside, particularly if they rotate between positions.

Returns, Trial Periods, and Warranties

Return policies, trial periods, and warranties are important consumer details to be aware of when mattress shopping. Trial periods give customers time to try out the mattress at home, and if the product isn’t a good fit, it can be returned. Most online brands have trial periods in the 100-night range, though some offer a full-year. 

Warranties are specific timeframes in which the company agrees to repair or replace the mattress in the event of defects. Warranties can vary from 10-20 years, and in some cases, a lifetime deal. When it comes to the mattress warranty, pay attention to the fine print, since some companies have specific restrictions regarding this.

Types of Memory Foam

There are many polyurethane foams around but not all of them are memory. Over the years, companies have experimented with this material and have come up with some variations that offer a different hug, contour, cooling, sinkage levels, and durability for the consumer. The following three categories are the majority of what you will see on the market.


Traditional is the standard version of memory foam and also the least responsive. This type gives the traditional hug and contour feel many people know and love. The typical density for this type is 4.0 – 6.0 PCF. 

  • Designed to enhance circulation and relieve stress on your joints
  • Good for side sleepers
  • Sleeps very hot

Open Cell

To battle heat retention, manufacturers came up with a solution known as open-cell foam. While it still provides a similar feel, small air pockets in the foam provide a cooler sleeping experience and enhanced response time.

  • Better cooling
  • Provides a similar feel to traditional memory foam
  • Faster response

Gel Foam

This is the most popular variation you will see – even on mid-grade mattresses these days. This gel is usually infused during the manufacturing process and evenly spread across the entire surface, or it can be incorporated as tiny beads or liquid.

Image showing four layers of foam designed to provide exceptional support

Example showing gel foam mattress structure (top to bottom) – Cooling gel, Memory foam, Transition layer, High-density foam

Gel solved the biggest memory foam issue of heat retention by evenly dispensing the heat instead of creating hot pockets. Don’t get fooled by low-ticket products advertising gel foam mattresses, as some just won’t do the trick. If you pick a quality product though, you can expect a much cooler experience than on a traditional one.

Here are a few tips to help pick a good product:

  • Liquid gel can sometimes provide better cooling compared to some beads.
  • Choosing a density of PCF 3.0 and higher can be an indication of a higher-quality product.
  • Opt for thinner, more breathable covers to help.

Plant-Based or Eco Foam

Plant-based or organic memory foam mattresses became some of the most popular on the market, though some are combined with traditional materials. The reason for this foam’s popularity is a more environmentally friendly manufacturing process and the replacement of petroleum-based substances with bamboo, tea, soy, or Aloe Vera. These materials are much better at heat distribution and provide much needed joint pain relief and better motion isolation.

  • No/low odors and off-gassing
  • Natural materials
  • Good for allergies
  • Better heat distribution and motion isolation
  • More expensive than traditional models

Proprietary Foam

To stand out, many companies have manufactured their memory materials with a twist. From quick responding gels to metal infusions, mattress companies often alter their foams with cooling substances like graphite or copper to keep you sleeping comfortably. However, the nuances of proprietary foam often come down to user preference and shouldn’t be the only factor in a mattress purchase.

Memory Foam vs. Other Materials and Types


Illustration of a Comparison of Memory Foam and Innerspring Mattresses

Coil mattresses (innerspring or coil-on-coil) provide more airflow and cooling than almost any other type. Nowadays, many products include a layer of memory foam on top for extra comfort. The combination of the two results in improved lifespan and cooling, and you still get that familiar foam feel.

Illustration of a Comparison of Memory Foam and Latex Mattresses

Latex is sometimes considered the creme de la creme of materials, and in most cases, the price of latex beds is higher. It’s not heat-activated and typically provides a much cooler sleep experience even compared to gel foam. Latex has a faster response and more bounce, but it has a completely different feel. You won’t get that much hug and deep contouring with this material. 

View Our In-depth Guide: Best Latex Mattresses


Illustration of a Comparison-of Memory Foam and Hybrid Mattresses

These days, many manufacturers think that combining different types of materials can negate all/most negative sides and you can end up with a much better product overall. A hybrid mattress combines coils with foam or latex. Hybrid mattresses typically offer more cooling and support because of the addition of coils. However, this beds tend to be priced higher than all-foam models.

Who Should Buy a Memory Foam Mattress?

  • You Need Pressure Relief – For anyone who reports waking up with achy joints, you will need a material that conforms to your body and provides pressure relief while staying supportive. Memory foam can be perfect for this, and it’s often the most recommended for pressure relief.

  • Side Sleepers – Contouring and hug are especially important for side sleepers as firm materials that do not conform tend to create pressure points on your shoulder and hip joints.

  • Couples – Memory foam’s ability to curb motion transfer is highly beneficial for couples. If your partner’s movements are impacting your quality a rest, a memory foam bed could be a great solution.

Who Shouldn’t Buy a Memory Foam Mattress?

  • Extra-Hot Sleepers – A significant issue with this material is that has a greater potential to sleep hot. Most manufacturers infuse cooling features into their memory foam, but if cooling is a top concern, a latex or latex hybrid mattress would be better.

  • Combination Sleepers – If you switch between positions, you will likely need a responsive bed that makes it easier for you to adjust. Despite its many benefits, memory foam doesn’t offer much bounce for repositioning. However, the coils in hybrid memory foam beds can provide some responsiveness for combination sleepers.

Density, ILD & Off-Gassing

During your consumer research, you will encounter products priced at a very affordable $200 and those at $2000, so obviously there is a difference. Let’s take a look at the most important factors that determine the quality of this material.


The density represents how much foam is built in each layer, however, thicker does not equal high density. Higher density will give you a longer lifespan for your new bed. This also means it could be much hotter to sleep on and you’d need a cooling measure to offset it.

You will most likely encounter the term PCF (pounds per cubic foot) and here are the three common levels of density:

  • Low – 3.5 PCF or below
  • Medium – 3.5-5.0 (often considered the Golden range to look for)
  • High – 5.0 or above

What do those numbers mean? They refer to the actual weight of the product, with a heavier weight representing a denser material. The weights are measured per cubic foot, so a mattress with a rating of four pounds indicates that one cubic foot of the material used would weigh four pounds.

As you would expect, heavier products are usually going to be more expensive than lighter options, but it also means that they can offer better support and are more durable.

Indent Load Deflection (ILD)

Indent Load Deflection (ILD) measures the firmness of the memory foam. The higher the ILD, the firmer the foam will be. The ILD does not reflect the overall firmness of the bed, solely the specific foam. ILD is calculated by the amount of force in pounds it takes for the material to compress. Additionally, thicker foams often have a higher ILD rating.

Want to Learn More? Read more about Indent Load Deflection.

Off-Gassing and Chemicals

Off-gassing is one of the leading complaints of memory foam beds. A new product is going to need to get rid of its chemical smell at first after decompressing, which is a process known as off-gassing.

This usually only lasts for a short period, but it can put some people off when they are just getting started on their new mattress. If you do decide to buy one, it is important to understand that off-gassing is likely to be part of the process.

Are There Affordable (Cheap) High-Quality Brands?

As competition in the online mattress space heats up, both established and startup brands are looking to diversify their offerings, and one way they’ve done it is to source higher-end materials, while still keeping their prices low. These constructions put a premium quality that is packed into impressively tall mattress profiles.

Memory beds in this space are emphasizing performance and quality, sourcing only the highest quality foams with additives like gels, graphite, and copper that update features like temperature control. Beds with performance foams are often priced high in the retail space, but an online sales model can make quality more attainable and affordable.

There are several ways that online companies manage to keep their prices low while still offering excellent value. Some own their manufacturing facilities and reduce the overhead that way. Online sales and made-to-order beds also cut down on the costs of storing inventory or displaying them in storefronts.

Should I Buy My Memory Foam Bed Online

The reason so many companies are exploring online sales models is that they can offer significant cost savings in more of a budget range by bypassing middlemen in the traditional supply chain. This enables them to offer the same quality you’d see in a brick and mortar store for much less.

Many people are nervous about buying something online sight unseen and may be tempted to pay higher prices for in-store models. However, research shows that you will receive a much better impression of whether a mattress works for you by sleeping on it for at least a few weeks rather than a quick 10-minute test drive in a store. Most online brands offer generous sleep trial packages and will refund your money if their product isn’t a perfect fit.

Mattress vs. Toppers

To save money, you can opt to purchase a topper rather than an entire mattress. However, mattress toppers are not always as effective as desired, especially when they are placed on an aging mattress.

If the underlying mattress is starting to sag or otherwise fail, it is unlikely that the topper is going to do anything to improve performance. Most likely, you are going to want to opt for a mattress rather than a topper when a good night’s sleep is your top priority.

What is a Memory Foam Mattress?

A memory foam mattress is a bed built with memory foam and either support foams or coils. Memory foam mattresses can vary in firmness, with some having a softer feel and others having a firmer feel. Memory foam beds are popular for people seeking a high-quality product that does a good job of providing pressure relief, comfort, and motion isolation. All-foam memory beds are typically cheaper than hybrid versions. Memory foam beds are more likely sleep hotter than latex mattresses, but manufacturers offset through valuable cooling features.

Is a Memory Foam Mattress Good for Your Back?

A memory foam mattress can be good for your back, because the material’s contouring abilities allow it to relieve pressure in the shoulders for optimal comfort. However, the mattress firmness must be supportive enough to ensure good spine alignment at the same time. If a memory foam bed cradles the sleeper so much that they sink too far, this could lead to poor alignment and back pain. Typically, medium-firm to firm memory foam mattresses are best for back sleepers, providing just enough pressure relief without sacrificing support. 

How long does a memory foam mattress take to expand?

Memory foam beds typically expand to their full capacity within 24-72 hours. However, you will notice that the bed begins to expand to the majority of its size within the first few hours. Many brands will advise that you wait 24 hours before sleeping on the bed to allow it enough time to expand. Waiting to sleep on your new mattress could also help if you’re sensitive to off-gassing, allowing the bed to air out without sheets and blankets over it.
