Leesa and Amerisleep are two of the leading mattress brands around right now, but many people struggle to choose between them due to their similarities. When looking at Leesa vs Amerisleep, it’s clear to see that the Amersleep AS3 and the Leesa foam mattress have plenty of things in common.

They’re both very well made, having similar firmness ratings and builds, and they offer a lot of comfort and support to a wide range of sleepers. No matter whether you tend to sleep on your front, back, side, or a combination of all three, these mattresses can provide you with high quality sleep each and every night, but there are some big differences between them. Read on to learn more.

Quick Comparison

They actually have quite a similar business model, aiming to offer versatile, universally comfortable mattresses with great value for customers and super levels of service too. When talking about the Amerisleep AS3 and the Leesa, it’s clear to see that the Leesa is the cheaper of the two foam mattresses, but the AS3 has some advantages too.

From the table above, we can immediately notice some differences in the way these mattresses are made. The Amerisleep comes with a much larger support core section, made up of 9 inches of polyfoam in total, while the Leesa features just 6 inches of polyfoam for support.

The Leesa then uses a mixture of polyfoam and memory foam for the comfort layers of its mattress, while the Amerisleep features nothing but memory foam. Both mattresses make use of similar covers. The Amerisleep is thicker and heavier overall.


Comfort is one of the most important elements of every mattress, but ‘comfort’ is such a broad and subjective term, which makes it hard to really gauge the actual comfort level of any mattress without delving deeper into the smaller individual aspects that help to make up our definition of comfort.

For some people, a comfortable mattress simply has to have good temperature control, for example, while others will find mattresses to be comfortable if they offer a good degree of responsiveness and bounce. When comparing Leesa and Amerisleep in these individual categories, we can start to see some differences emerge.

Firmness and support

Leesa vs Amerisleep: Detailed Mattress ComparisonBoth the Amerisleep AS3 and the Leesa mattress are quite similar in terms of firmness and support. The Amerisleep mattress is rated at 5.5 for firmness, while the Leesa is rated at 5, indicating that both mattresses can be described as being of ‘Medium’ firmness overall.

The Amerisleep offers a little extra support overall and offers more of a traditional ‘memory foam feel’, contouring around your body and adapting to your shape as you sleep. The Leesa, meanwhile, making use of the company’s own Avena foam, offers a more balanced foam feel.

Temperature control

Many people worry about buying foam mattresses and then feeling hot and sticky while they sleep, and it’s true that sleeping hot has been a common problem with lesser brands, but in the case of the Amerisleep and the Leesa, they both offer strong temperature control.

In this particular category, we have to give the win to the Amerisleep. It’s made from bio-based foams with an open cell structure resulting in stronger cooling effects for the sleeper, and its excellent celliant-infused cover also aids with breathability too. In spite of this, the Leesa is still relatively strong in this department and shouldn’t get too hot during the night.

Motion transfer

Motion transfer is a very important factor to think about if you’re going to be sharing the mattress with a partner. This factor shows how well the mattress is able to absorb the movement of another person, rather than allowing partners to easily disturb each other as they move around or get in and out of the bed.

In terms of motion transfer for Amerisleep vs Leesa, the Amerisleep comes out on top once more. This is due to its construction. The high quality layer of memory foam on the top of the Amerisleep allows it to absorb motion more easily than the Leesa.


When we talk about the responsiveness of a mattress, we’re looking at how it responds to any kind of pressure being placed upon it. A typical memory foam mattress, for example, will have quite a low responsiveness rating as the user will simply sink into the foam and find the mattress to be more hugging or contouring compared to something like a hybrid or latex mattress.

In this category, we can see a noticeable difference between the two mattresses. The Leesa, with its Avena foam build, is more responsive overall. It offers a balanced foam feel, allowing the user to roll around a little more easily than on the Amerisleep mattress, which offers a more typical memory foam sinking feel.

Resilience and bounce

Resilience and bounce are directly connected to responsiveness, and many people, particularly couples, favor a bouncier or more resilient mattress overall. If that’s the kind of mattress you like too, you’ll probably want to opt for the Leesa over the Amerisleep.

With its unique construction, the Leesa is able to offer a little more bounce and resilience than the AS3. It’s still not quite as bouncy as a latex mattress or an alternative hybrid mattress, but it’s still a little stronger in this category than the Amerisleep.

Edge support

Edge support determines how well a mattress is able to provide support and firmness around its corners and edges. If you want to sit on the side of the mattress at any time or lie near the edge of it while you sleep, you’ll need a mattress with decent edge support.

In this category, the Amerisleep manages to outperform the Leesa, but only by the narrowest of margins. As foam mattresses go, both the Amerisleep and the Leesa offer quite reasonable edge support, with the AS3 just doing a little more around the edges and able to stand out as slightly firmer.

Inflation time, off-gassing and smell

Leesa vs Amerisleep: Detailed Mattress ComparisonWhen it comes to inflation time, it’s best to leave both of these mattresses for at least 24 hours before sleeping on them. The Leesa might be ready a little earlier than that, but the difference in inflation time between these two mattresses is negligible at best.

For off-gassing and odor, it’s worth noting that both the Amerisleep and the Leesa are CertiPUR-US certified, while the AS3 also meets Clean Air Act standards and is made in a very eco-friendly manner. This means that the Amerisleep has no real odor to speak of, while the Leesa does sometimes exhibit a little bit of odor for the first few days, but this should fade quite quickly.

*Out of 10

This table gives us an indication of how well each of these mattresses perform for different types of sleepers, and we can see that the Amerisleep comes out on top in every category. It’s the better option for side, back, and stomach sleepers of all weights and sizes, being especially strong for back sleepers overall. The Leesa, however, still performs very well, especially for average sleepers and side sleepers. Plus, due to the Leesa’s higher responsiveness and bounce, it’s a good option for combo sleepers who tend to roll around and change position a lot during the night.

Sleep trial

A sleep trial is offered by many mattress manufacturers in the modern era, allowing users to test out mattresses for a set period of time to see whether or not they really enjoy them and want to continue using them for years to come. This is a great way to really get a proper feel for a mattress without any commitments or risks. For Leesa vs Amerisleep, we can see that both brands offer the industry standard 100-night sleep trial.

If anything goes wrong, it’s vital to have some cover from the manufacturer. Leesa and Amerisleep both offer the industry standard 10-year warranty.

In conclusion

So, in the overall comparison of Leesa and Amerisleep, which brand takes home the top prize? In terms of pure comfort and sleeping satisfaction, it’s arguable that the Amerisleep is the slightly better mattress. It’s more versatile and performs better for all kinds of sleepers, so if you want pure comfort and enjoy the memory foam feel, the AS3 is probably the better option overall, with its strong temperature control and edge support also standing out as key features.

However, at the same time, the Leesa does have its advantages that simply can’t be overlooked. It performs admirably in many categories, including edge support, temperature control, responsiveness, and bounce, and it’s a good match for combo sleepers too. Couples may also appreciate that added bounce and resilience, and the balanced foam feel of the Leesa might be favored by those who prefer not to sink into the typical memory foam mattress.

There’s also the factor of budget to think about. The Leesa is much cheaper than the Amerisleep overall, so if you have a fixed budget, don’t want to pay too much, or simply want to get the best bang for your buck, the Leesa might be seen as the better option. It does lack a little comfort in some areas when put up against the Amerisleep, but many of the differences between the two mattresses are quite minimal.

Overall, when it comes to Amerisleep vs Leesa, there’s no clear winner. Both of these mattresses have their plus points and their negative points, and they both offer a lot of versatility, comfort, and support to their users, which is why so many people have chosen these brands when shopping for a new mattress. Ultimately, the best option for you will depend on which factors are most important to your needs and lifestyle. For affordability and responsiveness, choose the Leesa. For overall quality and comfort, choose the Amerisleep.
