This Year’s Standout Memory Foam Mattresses
Our #1 Overall Mattress: The Amerisleep AS2 (Revere)
Pros: The Amerisleep AS2 (Revere) is our overwhelming pick for best of the year. You won’t find a more comfortable, sleep-boosting mattress at any price point. Yet at $1,099 it costs half as much as similar mattresses from competing brands, making it a no-brainer for our top spot.
They use the best materials and design, including fabric certified by the FDA1 to improve comfort and promote restful sleep. Plus they have the outstanding customer satisfaction scores — 99% of their customers rate them three or more stars out of five! Add an industry-leading warranty and generous 100-night trial, and you can see why they are our clear winner.
Cons: Compared to some of the truly budget memory foam mattress brands on the market, Amerisleep is more expensive. But given the quality of the materials, design, customer satisfaction, and company support we outlined above, it’s hands-down the best value. It’s like getting the Ferrari of mattresses for the price of a Ford.
Bargain Basement Deal: Signature Sleep 12” Memory Foam
Pros: You can own a memory foam mattress for less than $325 with the Signature Sleep 12” Memory Foam mattress. And unlike some of the other budget brands on the list, they offer a fairly generous 90-day trial period.
Cons: While we know some companies overcharge for their mattresses, there is also a point where you have to sacrifice quality to bring down the cost. The customer satisfaction scores for the Signature Sleep 12” Memory Foam mattress are below the average for the memory foam mattress category. Also, their warranty is only for one year, again suggesting that there is a tradeoff between cost and quality at this price point.
Our Memory Foam Mattress Review Process
Memory Foam mattresses are becoming more and more popular by the day. That’s because compared to traditional innerspring mattresses, which have been around for centuries now, they offer better support and comfort.
The proof is in the customer satisfaction scores. According to sites like Sleep Like the Dead, memory foam mattresses as a whole have an 80% average customer satisfaction score, while innerspring mattresses are more like 60%.
But with all of the different memory foam mattress models by traditional retail brands on the showroom floor — plus all of the new innovative online brands — it can be hard to figure out which mattress is right for you. So we created this guide.
Our goal is to help you cut through the clutter so you can easily see which beds in this year’s memory foam mattress lineup are the best.
Our reviews are based on what research says consumers care about the most when buying a mattress. For example, when asked about the importance of various comfort features, respondents listed targeted back support (81%), no sinking (73%), and stays cool (60%) as some of their top concerns.
Every year new technologies and models enter the memory foam mattress market, so keeping current on the latest trends and trade names is important when comparison shopping. Our latest mattress brand comparison takes a close look at a range of both higher-end and discount memory foam retailers to offer a broader scope for readers. To standardize the results as much as possible, we based the reviews on each brand’s mid-range mattress (11-13”).
The Best Memory Foam Mattress: Amerisleep AS2 (Revere)
The Amerisleep AS2 (Revere) is our overwhelming winner for best mattress of the year. So we wanted to spend some time digging into what makes it so great. That way when you read through the rest of our comparisons, it will be easy to see how Amerisleep is a standout in virtually every category.
First, and most importantly, the Amerisleep AS2 (Revere) is off-the-charts comfortable because of new materials and technology they’ve included in their design. But don’t just take our word for it — look at the third-party-verified reviews. 99% of AS2 customers rate it three or more stars out of five.
It all starts with the cover. It’s the closest part of the mattress to your skin, making it an important element of the mattress that other companies sometimes overlook.
Amerisleep is the only mattress brand on our list that uses Celliant® in its covers. This high-tech fabric is designated as a medical device by the FDA1 and contains fibers that safely convert body heat into infrared light. This energy penetrates into the muscle and tissue to promote a temporary increase in local blood flow and helps increase comfort and promotes restful sleep. Clinical trials showed people fell asleep 15 minutes faster on average when using a mattress with a Celliant® cover. That’s worth nearly two extra hours of sleep per week!
When you go beneath the cover, the Amerisleep AS2 (Revere) has enhanced every foam layer of their mattress.
The foam top layer, often called the comfort layer, is made of their proprietary Bio-Pur foam. This proprietary foam is made to have an “advanced open-cell structure” with two key benefits. First, it allows more air to flow through the foam, preventing the common complaint of overheating that other memory foam mattresses have. It also allows the foam to bounce back to its original shape faster. That way as you move throughout the night, the foam responds to your new position and you don’t feel “stuck.”
The Amerisleep AS2 (Revere) also has a transition foam layer beneath the Bio-Pur comfort layer. This layer contains Surface Modification Technology (SMT), which provides additional, targeted pressure relief on common pain points like the lower back and shoulders. Remember 81% of consumers said that target lower-back support was important to them when selecting a mattress. SMT works because the foam contains precision-cut channels that allow additional room for it to compress and expand. As an added bonus, these channels also create even more room for air to flow out of the mattress, further enhancing the coolness of the AS2.
Finally, the base layer of the Amerisleep AS2 (Revere) is made with their Bio-Core foam. This highly durable foam can stand up to decades of use — and Amerisleep proves that by having the longest warranty of any memory foam mattress brand. They offer two decades of coverage, with the first 10 years providing a full replacement and the second 10 years offering a prorated replacement.
Speaking of looking out for their customers, Amerisleep also provides an outstanding 100-night trial. In order to know for sure whether a mattress is right for you or not, you have to spend more time on it than a few minutes on a showroom floor. So you can use the Amerisleep AS2 (Revere) in your own home, in your actual bedroom, for more than three months to see if you like it. If for any reason you’re not completely satisfied, you can get a full refund. All they ask in return is that you give it a fair chance and try it for at least 30 nights, since any new mattress can require an adjustment period.
Lastly, the Amerisleep AS2 (Revere) is their medium-firm model, ideal for back and stomach sleepers. But if you have a different sleep style or just prefer a softer or more firm mattress, Amerisleep offers a total of five comfort levels for you to choose from.

Our Memory Foam Mattress Rankings for 2018
The brands and models according to rating are as follows:
- Amerisleep AS2 (Revere) Bed (available from Amerisleep.com)
- BedInABox Tranquility Gel (available from BedInABox.com)
- Serta iComfort Savant Everfeel Plush (available from Serta.com and dealers)
- Comfort Dreams Select-A-Firmness (available from Overstock.com)
- Signature Sleep 12” Memory Foam (available from Walmart.com and Amazon.com)
- Simmons Comforpedic Balanced days / Nourishing Comfort (available from dealers)
These mattresses as a collective group tend to rank among the highest in owner ratings (80% of owners report satisfaction) among all mattress types, significantly outperforming the average spring mattress (63% satisfied). However, there are still a few issues that tend to pop up with some memory foam mattresses, which include sleeping hot, chemicals or odors, feeling stuck or trapped, and premature softening or compression. Different brands can exhibit vastly different performance due to different memory foam formulations, densities, and mattress compositions.
Memory Foam Mattress Reviews: Comfort & Composition
Comfort Dreams and the beds offered by Amazon and Walmart all use conventional foam, while Serta iComfort, Simmons Comforpedic and BedInABox feature at least some gel memory foam, and Amerisleep uses plant-based foam. Gel-based products usually tout cooler sleeping as a benefit, while plant-based foams claim cooler sleep and less odor or offgassing.
These beds vary on the amounts of actual memory foam included with Signature Sleep, Simmons, Amerisleep and featuring up to 4 inches or more, and BedInABox, Comfort Dreams and Serta featuring 3.5 inches or less. The rest of the mattresses are composed of foam support cores or other types of foam, depending on the model.
Mattresses with more memory foam tend to contour to sleepers better. Petite individuals and stomach or back sleepers may be comfortable on 2-3”, while medium to large framed individuals and side sleepers will want at least 4” for pressure relief.
Additionally, the Amerisleep AS2 (Revere) has improved how comfortable memory foam can be by adding Celliant® to their covers and Surface Modification Technology (SMT) to their transition layer.
Celliant® is designated by the FDA1 as a medical device, and it safely converts body heat to infrared. This energy penetrates into the muscle and tissue to promote a temporary increase in local blood flow and helps increase comfort and promotes restful sleep.
SMT provides additional, targeted cushion and support for common pain points like the lower back and shoulders. The foam contains precision-cut channels that allow more room for it to expand. Not only does this allow for additional cushion, but it also allows even more air to flow through the mattress — keeping you cool while you sleep.
Memory Foam Mattress Reviews: Density & Firmness
Density is a measure of weight, referring to the heft of one square foot of material. Density affects longevity (denser foams tend to be more durable), feel (less dense foams generally respond to movement quicker), as well as heat and odor (lower densities should have fewer heat and odor complaints than high).
A mid-range measurement of around 4.0 pounds is considered the ideal range for comfort and durability. Anything less may compromise durability, while anything firmer than 5.5lb may be overly viscous. In reviews, medium density beds tend to be the top performers for most people.
BedInABox uses what would be considered low density memory foam, at or below 3.0 lbs. Comfort Dreams uses foam between 2.5 and 4.0 lbs depending on the firmness ordered. Simmons Comforpedic has 3.5 and 4.5 lbs in their mattress. Serta has 3 and 4 lb in their mattresses. Amerisleep and Signature Sleep use 4.0 lb memory foam.
The densities of the core layers can be harder to find, with 1.5 lb and higher considered ideal for long-term support. Most major brands do not disclose this information at all. Amerisleep uses 1.5 lb cores, BedInABox uses 2.5 lb cores, Comfort Dreams uses 1.4-1.5 lb cores, and the others are unknown.
As far as firmness, the mattresses in this range tend to be medium to medium-firm, with the exception of the Comfort Dreams which comes in three firmnesses (however user reports suggest all tend to feel about medium). Medium is the firmness that will feel best for the widest variety of people.
Memory Foam Mattress Reviews: Heat
Overall, about one in ten reviews for memory foam mattress complain of sleeping uncomfortably hot. Conventional foams like those in Comfort Dreams tend receive the most complaints for heat retention.
Gel foams, like those in the Serta and Simmons mattresses were made in order to help reduce heat complaints, but have had limited success. Reviews show a slight difference in heat complaints, with the effects noticeable primarily in the first 10-15 minutes (until the gel meets body temperature).
Plant-based memory foams like those from Amerisleep have an open-cell structure that improves airflow which helps to keep temperatures down. A study conducted by Cargill found plant-based foams to be more breathable than gel foams.
Finally, because the Affinity transition layer with SMT in the Amerisleep AS2 (Revere) contains additional airways, it provides even more cooling on top of the breathable foam.
Memory Foam Mattress Reviews: Odor
In general, about 15% of reviewers report significant odor or off-gassing, usually attributed to chemicals used in manufacturing and dissipating within 1-3 weeks. Conventional memory foams are entirely synthetic, or petroleum-based. Synthetic foams typically receive higher reports of odors than their plant-based counterparts, especially very dense foams.
Gel foam mattresses are essentially conventional foam with gel added. Gels are made from a number of different chemicals and can contribute to odor or off-gassing problems, though some gel lines have fewer complaints of odor than traditional foams.
Plant-based memory foams replace a portion of petro products with plant-based oils and ingredients, and manufacturers are often more conscious of avoiding volatile organic compounds (VOCs).
Amerisleep is also a standout in this category. Because they use a patented process called Variable Pressure Foaming (VPF), they are able to capture virtually all emissions from the foam by making it in an enclosed chamber. On top of reducing air pollution, this also helps virtually eliminate any odor concerns.
Memory Foam Mattress Reviews: Durability
For durability scores we looked a complaints of sagging or impressions in owner reviews compared with other consumer publications’ durability scores for each brand. The iComfort Savant, Optimum Inspirations, Comfort Dreams Select-a-Size, Simmons and Signature Sleep rate below average for durability based on significant reports of sagging and impressions. These mattresses are estimated to last between 3-6 years. Amerisleep and BedInABox all received fairly low complaints of impressions or wear, and would likely last between 7-8 years or more. Durability depends on a variety factors, including the densities of all the foams, user care, sleeper weight and frequency of usage, so significant variation can exist here.
Memory Foam Mattress Reviews: Warranty & Returns
The warranties offered varied significantly. The Signature Sleep 12” offers only a one-year warranty. Amerisleep and BedInABox offer 20 years with 10 years of full coverage. Simmons and Serta each offer 10 years total with full coverage for the duration.
Trial periods, or the length the mattress can be returned, also varies. Overstock does not accept returns on their mattress. Amerisleep and Signature Sleep have 90 day return periods, while Serta and BedInABox offer 120 days. Simmons returns are determined by the various retailers who sell their products. It is important to note that other brands sold through dealers may be subject to the individual retailer’s policies that may be shorter than the manufacturer’s policy, also.
Memory Foam Mattress Reviews: Owner Satisfaction
For most of the brands, memory foam mattress reviews showed above-average scores. The highest rated models were the Amerisleep AS2 (Revere) (94%) and BedInABox Tranquility Gel (86%) . Reviewers of both lines generally praised the value of their mattress, service received and comfort/pain relief. Amerisleep customers like the health aspects of sleeping on a plant-based mattress.
Comfort Dreams Select-A-Bed. Serta iComfort Savant Everfeel and Temperpedic Contour Rhapsody Breeze received average reviews at 81% and 82%. Overstock’s customers reported liking the low price of the mattress. With the Serta iComfort Savant Everfeel Plush, people expressed good comfort, but sometimes complained of the costs, heat and odor.
The Signature Sleep 12”, Simmons Comforpedic had ratings of 78%, 77% and 77%, respectively, with reviewers generally praising comfort, but complaining of costs (Simmons), durability, or service issues.
Memory Foam Mattress Reviews: Price
The Signature Sleep 12” and Comfort Dreams Select-A-Firmness are the most inexpensive at $319.99 and $599.99 respectively. In the middle, the BedInABox Tranquility Gel is priced at $1,299, the AS2 (Revere) from Amerisleep at $1,099 and the Serta iComfort is $1,574. Simmons does not list the price of their Comforpedic mattress, though it averages around $1800-$2000 depending on retailer.
Summary of Memory Foam Mattress Ratings
The collection of diverse mattress brands compared in this article highlight some interesting trends, namely that the more expensive big-name brands don’t necessarily offer high quality or better owner satisfaction than mid-range models. The two best-rated beds both come from online retailers and are priced in the middle-range for this category, while even the low-end beds scored fairly well with shoppers.
If you are shopping for a memory foam mattress this year, it might be wise to consider looking beyond the local mattress store and to compare the actual value and satisfaction potential when researching products, not just the brand names. More retailers offering their products online and shipping innovations have made internet mattress shopping a convenient option.
That’s why after our full analysis there was one clear choice for the best memory foam mattress of the year — the Amerisleep AS2 (Revere).
