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”) and rated them on important factors such as density, firmness, and warranty, as well as owner reviews.

The brands and models according to rating are as follows:
- Amerisleep Revere Bed (available from Amerisleep.com)
- BedInABox Tranquility Gel (available from BedInABox.com)
- Serta iComfort Savant Everfeel Plush (available from Serta.com and 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.
The Tempurpedic, Comfort Dreams and the bed offered by Amazon and Walmart all use conventional foam, while Serta iComfort, Sealy Optimum, Simmons Comforpedic and BedInABox feature at least some gel memory foam, and Amerisleep uses plant-based. 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 Sealy, Signature Sleep, Simmons, Tempurpedic, 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.
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 is 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, and Tempurpedic uses 4 and 7 lb density foams. Sealy does not disclose the densities in their mattresses, though it’s estimated they use around 4.0 lb density.
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.
Overall, about one in ten reviews for memory foam mattress complain of sleeping uncomfortably hot. Conventional foams like those in Comfort Dreams and Tempurpedic tend receive the most complaints for heat retention.
Gel foams, like those in the Sealy, 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.
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).
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. Tempurpedic, 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.
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. Sealy, Simmons and Serta each offer 10 years total with full coverage for the duration. Tempurpedic has a 25-year warranty with 10 years of full coverage.
Trial periods, or the length the mattress can be returned, also varies. Overstock does not accept returns on their mattress. Amerisleep, Tempurpedic and Signature Sleep have 90 day return periods, while Serta and BedInABox offer 120 days. Sealy and 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.
For most of the brands, memory foam mattress reviews showed above-average scores. The highest rated models were the Amerisleep 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, while Tempurpedic reviews did mention price as an issue. 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 and Sealy Optimum Inspiration had ratings of 78%, 77% and 77%, respectively, with reviewers generally praising comfort, but complaining of costs (Sealy and Simmons), durability, or service issues.
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 Revere from Amerisleep at $1,499 and the Serta iComfort is $1,574. On the high-end is the Sealy Optimum at $1,999 (set) and the Tempurpedic Contour Rhapsody Breeze at $3,899. Simmons does not list the price of their Comforpedic mattress, though it averages around $1800-$2000 depending on retailer.
Overview 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. If you can’t find a good mattress, you aren’t looking hard enough.
