Full Mattress Review

Saatva and Amerisleep have a lot in common: Both mattress companies were founded in 2010 and currently assemble their mattresses in the US. Additionally, both prioritize using safe, eco-friendly materials in their beds.

But there are plenty of differences between the Saatva Classic, Saatva’s flagship innerspring mattress, and the Amerisleep AS3, one of Amerisleep’s all-foam bed offerings, particularly in terms of feel, standout features, and price point. 

We performed hands-on testing of both mattresses and examined Saatva and Amerisleep policies and online customer reviews in order to help you identify which of the two beds better suits your needs and preferences.

Our Testing Team’s Take

In our Seattle-based Test Lab, our testing team has examined nearly 2,000 mattresses over less than a decade. Through this hands-on testing, we’ve developed a unique product research methodology that forms the backbone of our mattress rating system. 

Using cutting edge technology, we pressure map each bed to identify where pressure points may form. We use similarly advanced tools to measure motion transfer across each mattress’ surface and heat retention.

We also have testing team members take mattresses home for weeks at a time, allowing them to mimic real-world use. Because our team members represent a variety of body weights and sleep position preferences, their perspectives can help you identify which might be the best mattress for you.

Our Verdict  

Due to differences in materials and firmness, the Saatva Classic and Amerisleep AS3 excel in different areas and appeal to different sleepers. 

The Saatva Classic received a perfect score on temperature regulation, which is very rare in our testing. For this reason, people who tend to sleep hot may prefer it over the Amerisleep, which, like many all-foam beds, can tend to retain heat. Conversely, the Amerisleep AS3 stands out in terms of motion isolation, making it a tempting option for couples who share a bed, while motion may transfer across the Saatva.

“The Saatva Classic is one of the sturdiest mattresses around. I also like how cool the Classic sleeps. There’s hardly any heat retention from the foam layers, and the cover is nice and breathable. If there’s one downside, I’d say it’s motion transfer. The surface is pretty bouncy, and you’ll feel some movement during the night if you sleep with a partner.”

Both beds rate high on pressure relief, but the feel of these beds differ. As an all-foam model, the Amerisleep contours more deeply, appealing to sleepers who like to feel “hugged” by the bed. While memory foam in the Saatva also gives it a tiny bit of “hug,” two layers of coils make this model feel bouncier and more responsive.

The Amerisleep AS3 performs best for side sleepers that weigh less than 230 pounds and back sleepers that weigh between 130 and 230 pounds. Because the Saatva Classic is available in three firmness options, people of all body weights and sleep position preferences can find the support they need on it.

“I enjoyed the AS3 for its close contour, even though there wasn’t much bounce or pushback. Anyone who wants to be hugged by their mattress should enjoy this model, but people over 230 pounds will probably sink a bit too much.”

Prices between these mattresses are quite different, so budget might factor in for many shoppers. Because of its use of two steel coil layers, the Saatva Classic costs more than double the price of the Amerisleep AS3.

Construction and Materials

The Saatva Classic and Amerisleep AS3 are different types of mattresses. The Saatva is an innerspring bed, with a support core made up of innerspring coils, and the Amerisleep is an all-foam bed, with a support core made up of polyfoam. One similarity that the two beds share is the inclusion of memory foam in the comfort system.

Saatva Classic Breakdown 

Shoppers can find many options in the Saatva Classic line. This mattress model comes in three firmness levels, which rate as soft (3), medium-firm (6), and firm (8) on our 10-point firmness scale. The bed is also available in two profile options measuring 11.5 and 14.5 inches. All of the Saatva Classic mattress options contain five layers, which includes the cover.

The cover is organic cotton and the company says it works well for sleepers with allergies. It has also been treated with a botanical-based substance called Guardin^TM, which is meant to protect against the growth of mold and bacteria. The Saatva Classic’s first comfort layer is polyfoam that has been quilted directly into the cover to add cushion and form a Euro-top.

The next comfort layer is made of memory foam, which has earned CertiPUR-US certification for being free from a variety of potentially toxic chemicals. This layer also incorporates a zone called the Lumbar ZoneⓇ, which means extra support beneath the lower back area. The next layer down consists of recycled steel pocketed microcoils, which also contain a firmer Lumbar ZoneⓇ region. Together, these zoned layers promote spinal alignment and prevent back pain during sleep.

A support core of larger innerspring coils sits at the bottom of the bed. Both coil layers allow for ample airflow, which is likely why the bed scores so highly on temperature regulation. In addition to CertiPUR-US certification, the mattress is GreenGuard Gold certified and has earned endorsements from the Congress of Chiropractic State Association and the American Chiropractic Association.

Amerisleep AS3 Breakdown 

The Amerisleep AS3 comes in one firmness option, which is medium (5), and is 12 inches tall. Out of four layers, the first layer is the bed’s cover, which is a fabric blend that includes polyester, cotton, and spandex. The cover is designed to keep sleepers cool, and it converts body heat into far infrared energy, which is intended to promote recovery and improve sleep quality. 

Beneath the cover sits a 3-inch memory foam comfort layer that contours to the body and relieves pressure. The next layer measures 2 inches in thickness and is made of zoned polyfoam using what the company calls HIVEⓇ technology. This layer provides additional cushion while also keeping sleepers from falling too far into the mattress. Its zoned nature allows a sleeper’s shoulders and hips to sink into the mattress a little more deeply than the rest of their body, so the spine can stay aligned.

Amerisleep calls the support core of this bed the Bio-CoreⓇ base. It’s made of high-density polyfoam that provides support, gives the bed its firmness, and adds to the durability of the mattress. Like the Saatva Classic, foam layers in the Amerisleep have received CertiPUR-US certification and are designed to resist dust mites and mildew.

Mattress Sizing and Weight 

The Saatva Classic and Amerisleep AS3 are available in twin, twin XL, full, queen, king, California king, and split king sizes. The Saatva Classic is also offered in a split California king size. Split sizes may especially interest couples who share a bed and like the Saatva Classic, because the nature of a split bed virtually eliminates motion transfer that can happen on that model.

The Saatva Classic comes in 11.5 and 14.5-inch profiles, and the Amerisleep AS3 as a 12-inch profile. The 14.5-inch Saatva may require deep-pocketed sheets, while the other models should easily fit standard sheets.

Both profile options for the Saatva Classic weigh over 100 pounds. Although Amerisleep doesn’t share the weight of their AS3 model, it likely weighs less, since foam tends to weigh less than steel coils.

Performance Ratings 

Both the Saatva Classic and Amerisleep AS3 perform very well at relieving pressure. Most sleepers who find the firmness levels appropriate won’t have to worry about forming pressure points on these beds. 

The mattresses differ in the way they feel, though. The Amerisleep AS3 closely conforms to the body, while the Saatva Classic only lightly conforms and has more bounce. Sleepers who want to sleep “in” their bed prefer the Amerisleep, while those who want to sleep “on” their bed prefer the Saatva.

The Amerisleep AS3 received its highest ratings from side sleepers weighing less than 230 pounds. Back sleepers weighing between 130 and 230 pounds also found that the bed could adequately support them. Back sleepers outside of that weight range couldn’t find much comfort on the bed, and neither could stomach sleepers of any body weight.

The Saatva Classic rated highly among a wider variety of sleepers, because it’s available in three firmness options. Among side sleepers, those weighing less than 130 enjoyed the soft (3) model most, while those weighing over 130 preferred the medium-firm (6) model. Back and stomach sleepers weighing less than 130 pounds preferred the soft (3) and medium-firm (6) models, while those weighing over 130 pounds preferred the medium-firm (6) and firm (8) models.

The Saatva Classic is a strong choice for people who tend to sleep hot, while the Amerisleep AS3 can retain heat. That said, people who have slept comfortably on all-foam beds before may find the Amerisleep AS3 suits them just fine. Moving around on the Saatva is facilitated by its bounce, whereas the conforming foam on the Amerisleep can impede movement. 

With firm coils and reinforced perimeter layers, the Saatva offers superior edge support. However, it also costs much more than the Amerisleep, and some shoppers will find its high price-tag out of budget.

Mattress Pricing 

The Saatva Classic costs over double the price of the Amerisleep AS3. This price difference largely stems from the two coil layers in the Saatva — steel coils cost much more to manufacture than foam layers.

More generous policies also help explain the Saatva Classic’s relatively higher price. Saatva offers a 365-night sleep trial, while Amerisleep offers a 100-night trial. The Saatva limited warranty lasts a lifetime, while the Amerisleep warranty lasts 20 years. Finally, Saatva offers free White Glove Delivery and mattress removal on all orders, but Amerisleep does not.

What Customers Are Saying

The Saatva Classic boasts thousands of online customer reviews with a nearly perfect average rating. Many rave about the mattress’ comfortable feel and ability to stay cool throughout the night. Others compare the bed to those that are in luxury hotels. Some reviewers come back years after purchasing the mattress to share that it is still performing well. Those who do have complaints generally mention delivery delays or customer service misunderstandings, rather than issues with the bed itself.

Although the average rating given in Amerisleep AS3’s online reviews aren’t quite as high as that of the Saatva Classic, the bed does receive overwhelmingly positive ratings and reviews. As with the Saatva, most reviewers mention comfort and improved sleep on the mattress. 

Although our testing found the AS3 could retain heat, there are also many reviewers saying that it sleeps cool. Negative reviews are generally from stomach sleepers or sleepers weighing over 230 pounds, which is a good reminder to consider your body weight and sleep position preference before making a purchase.
