The brand differentiates itself with a more eco-friendly approach, and its foams have no harmful VOCs and are Certi-Pur certified to be free of toxins such as formaldehyde.

Tempurpedic TEMPUR-Cloud Supreme Breeze
Tempurpedic is the industry leader for memory foam and first brand to bring it to market in the 90s. While they use a proprietary and protected formula, it is believed to be traditional petroleum-based polyurethane memory foam. The TEMPUR-Cloud line was introduced in 2010 as the softer, plusher alternative to the core line, and the Breeze collection came out in 2012 to address concerns of sleeping hot. Tempurpedic bills its mattress line as safe and free of harmful VOCs but remains fairly vague. The details for TEMPUR-Cloud Supreme Breeze are as follows:
- Profile Height: 11 inches
- Composition: 2 inches TEMPUR-ES® Breeze material (4.1 lb), 2 inches TEMPUR-Climate™ material (4.1 lb) over 7 inch Support Core (2.2 lb).*
- Firmness: Extra soft, with moderate conformity.
- Cover: Microfiber sides with CoolMax top.
- Fire: Barrier sock, unknown composition.
- Origin: Made in the USA.
- Price Range: Twin $2749, Queen $3199, King $3699
*Note, Tempurpedic layer thickness and foam densities are estimates based on available research, as the brand does not disclose this information. There is some speculation (MattressUnderground.com) that support cores for some or all models are now 1.5lbs, but information is limited.
The chart below compares the Amerisleep Liberty and Tempur-Cloud Supreme Breeze using product specifications and owner reviews. Review data from Amerisleep comes their website, which uses a third-party verified reviewing system. Tempurpedic recently took down reviews on their website, so we used the review information that existed prior to July and trustworthy third party review websites to paint a picture of the Supreme Breeze.

|Type||Traditional Memory Foam||Plant-Based Memory Foam|
|Memory Foam Density||4.1 lbs||4.5 lbs|

|Average Owner Review||4.2 stars||4.6 stars|
Memory foam mattresses are made using polyurethane foams with visco-elastic properties for contouring support in the upper layers and solid support cores in the lower layer. Not all mattresses are manufactured the same, although in general Amerisleep and Tempurpedic models use a somewhat similar method overall. This includes a foam core topped with several inches of memory foam. Both models have 4″ of memory foam, though the profile height differs by one inch likely due to differences in core height. Both have covers with microfiber/microsuede sides, with the Amerisleep Liberty featuring a bamboo blend top and the Supreme Breeze a Cool Max fabric top. Cool Max fabric is made of polyester and designed to have moisture-wicking properties.
Memory Foam Density
Density is an important factor to consider when comparing memory foam beds because it can be predictive of several factors including quality, longevity, and comfort. Higher density foams tend to last longer, as the average life span for low density (less than 3.5 lbs) beds is 5 years versus 9 years for high density (5+ lbs). Lower density foams are quicker to compress and loose support, which can result in reduced comfort over time. Amerisleep uses 4.5 lb density memory foam and a 2.0 lb density core in the Liberty. Tempurpedic does not disclose their mattress specifications, though previously the Cloud line was identified as using 4.1 lb density memory foam. Tempurpedic cores were said to be 2.2 lb density, however there are some concerns that this may have been reduced to 1.5 lbs. Both brands’ memory foam is in the middle range for density.
Responsiveness is an integral portion of the design elements that contribute to comfort that refers to how quickly the foam re-contours or returns to its original shape. Amerisleep memory foam has a response time of 6-8 seconds, and firmness is stable across a broad temperature range as it is temperature neutral. Tempurpedic mattresses average a slower response time of 45-60 seconds, with the lower-density cloud on the lower end of this spectrum. Reviewers occasionally mention difficulty turning over or getting out of bed since the foams takes some time to come back.
Chemicals and Off-Gassing Odors
Off-gassing can be used to refer to either the new odor associated with nearly every product, or to a more concerning release of petroleum-based chemicals which can occur over the lifetime of a product. Odor is often cited as a concern by shoppers sensitive to smells and chemicals, but tends to dissipate within 1-3 weeks. Amerisleep touts no offensive odor and no harmful VOCs as a selling point, and in 140 Liberty Bed reviews only 3 mention odor negatively (2%). Tempurpedic makes no mention of odors, and of the 8 reviews they previously had on their website 4 of 8 mentioned strong odor (50%), and 2 of the other 13 reviews we found mentioned the issue (29% overall).
Heat Retention / Sleeping Hot
Hot sleep is a problem that has received complaints since memory foam mattresses were introduced to the market. Because memory foam contours to the sleeper’s body, foams that are not breathable can cause some heat retention especially for naturally hot sleepers. In Amerisleep Liberty reviews, 2 of 140 owners mentioned that the slept hot (about 1.4%). Though Tempurpedic touts the Breeze line as cool, 3 of the 21 reviews we found mentioned sleeping hot (about 14.3%). To supplement the limited reviews for the Supreme Breeze, research from SleepLikeTheDead.com indicates average heat complaints of 10-14% for the brand as a whole with no significant differences for the Breeze lines. The average complaint rate for memory foam in general is about 10%, so Tempur-Cloud Supreme Breeze sleeps hotter than average, while the Amerisleep Liberty shows markedly low complaints for heat.
The 140 Amerisleep Liberty reviews had an average rating of 4.6 out of 5, with 98% of reviewers recommending the bed to a friend. The 8 reviews formerly on Tempurpedic’s website average 4.0 out of 5, with 87% recommending. The additional 13 reviews showed an average of 4.3 out of 5, with 85% recommending the bed. Reviews from the Liberty provide a larger and more conclusive sample which is lacking for the Supreme Breeze, but in the data available the Amerisleep Liberty rates 0.4 points higher and is more likely to be recommended. However, both beds have good overall ratings compared to average memory foam rating scores of 4.0 or 80%.
Price is an important aspect when purchasing a new bed, as everyone wants to get a good value for their money. The Amerisleep Liberty bed is $1199 for a queen size (plus tax in AZ only), while the TEMPUR-Cloud Supreme Breeze is $3199 (plus taxes in all states). The difference of $2000 is quite significant, making the Supreme Breeze 63% more expensive than the Liberty.
Memory foam mattresses, as well as latex, provide the highest overall customer satisfaction ratings on the market. Approximately 81% of owners are happy with their choice, compared to 62% for coil mattresses. Consumers are urged to compare specifications, reviews, customer service, warranties and in-home trials as well as the items mentioned above when determining which is the best choice for their needs personal needs, as each buyer will have their own preferences that may give one bed an advantage over the other. Understanding the differences between the Amerisleep Liberty memory foam mattress and Tempur-Cloud Supreme Breeze will help you make the best choice for your personal preferences and needs.
