Amerisleep Mattress AS3 Review


We’ll start off by evaluating the mattress’s construction. The AS3 is made up of four layers to ensure that you have an amazing night’s sleep every night, no matter the temperature, your movement, or who is lying next to you.

  • The cover layer is made from ultra-breathable fabric to ensure the ultimate in comfort, despite any changes in the room’s temperature. 
  • Next is the BioPur layer. This layer has an open-cell design that ensures you’ll stay cool and never get stuck in the same position. The material contours to your body, alleviating any pressure points and allowing you to “bounce” from one position to another without ever feeling stuck. 
  • Following this, there’s the HIVE transition layer. According to the Amerisleep AS3 mattress reviews, this layer provides targeted support to ensure that your body is aligned as you rest. The HIVE transition layer cushions your shoulders and hips, while supporting your legs, back, and head. 
  • The Bio-Core layer offers you incredible support. This layer is designed such that you won’t need to replace your mattress for decades. It won’t sag and will continue to offer support for your full body. 


This mattress offers all the support you need, whether you sleep in one position all night long or toss and turn as you dream. You’ll find that many Amerisleep AS3 reviews talk about the fact that this mattress was designed to keep your body perfectly aligned. 

There’s minimal sinkage on this mattress as its four layers ensure that you’re properly supported. This memory foam bed in a box is firm, but not so firm that it sacrifices comfort. We’d say it’s just the right amount of firmness and cushioning to keep you comfortable all night long. 

Temperature Neutrality

The top cover layer of this mattress is made from breathable material designed to keep you cool during the night—and the BioPur layer below it aids in this process. If you’re a hot sleeper, this mattress will help prevent you from overheating while you sleep. It controls your temperature so that you’re neither too hot nor too cold while you catch some Zzzs. We will happily tell anyone reading this Amerisleep AS3 mattress review that this product is great for hot sleepers and will keep your temperature under control. 

Edge Support

If you’re one of those sleepers who tends to end up on the edge of the bed quite frequently, fear not. There’s adequate edge support, and you won’t find yourself falling off the bed or waking up in an uncomfortable position with this product. 

The BioPur comfort layer ensures that all your pressure points are covered, and that includes when you’re lying on the edge of the bed. Of course, the weight you put on the mattress, especially along the edges of the bed, can make a difference. However, for the most part, AS3 Amerisleep reviews insist that the edge support on this product is top quality. 

Motion Transfer

The four layers of the materials making up this mattress guarantee that you’ll always be comfortable. And the same goes for your sleep partner. This means that there’s little motion transfer, which is great when one person sharing the bed is a rough sleeper who tosses and turns. You can relax on this mattress knowing that your movements won’t affect your partner, and vice versa.

Durability and Maintenance

Product Lifetime

All Amerisleep AS3 reviews will note that the brand has a 20-year warranty, meaning this mattress should ideally last more than 20 years. This means that if you find a defect in the first 10 years, this mattress will be promptly replaced. And if you find a defect in the following 10 years, you’ll receive a prorated replacement. This is great because when you invest in a mattress, you don’t want to have to consider replacing it after just a few years. 


With the Amerisleep AS3, you’re in luck because the materials used in all four layers ensure that this mattress is durable and long-lasting. There’s no need to flip the mattress or turn it to keep it in good condition. 

However, it’s highly advised that you put this mattress on a stable bed base so that it lasts as long as it’s designed to. In this review of the Amerisleep AS3, we also advise that you use good sheets to cover the mattress so that it remains breathable and is able to regulate temperature. Of course, using a mattress protector is always a good idea if you want your mattress to last.

Terms of Sale

Trial Period and Return Policy

One of the best parts of putting together this Amerisleep AS3 review is that we get to let you know that you have 100 days to test out this product. If at any time during that period you feel that this isn’t the mattress for you, you can return it for a full refund of the product’s cost. And the 100 days don’t start at your purchase but rather when the mattress is delivered. 

Simply contact the company for a return, and they’ll make arrangements for a courier and for your mattress to be recycled in the best possible way.

Shipping Options

You’ll see in our Amerisleep review on the AS3 that curbside shipping is absolutely free as long as you live in the contiguous US. All mattresses will be shipped through FedEx in 3–5 business days and delivered to you in 1–5 business days after they’ve been shipped.

As mentioned previously in this Amerisleep AS3 memory foam mattress review, there’s a 20-year warranty on this mattress. For the first 10 years, if you have any issues with your Amerisleep AS3 mattress, you can send it back with nearly any defects and have it replaced. For the second 10-year period, the company will offer you a prorated replacement. If that isn’t a sign that this company truly believes in its products, then we don’t know what is!


Prices vary based on mattress sizes. Before ordering any memory foam mattresses, compare the different mattress dimensions so you can be sure of the mattress size you need. After all, different rooms will fit a king bed vs. a queen bed better, so really consider your needs and space.

Who Can Benefit From This Mattress?

  • People who sleep hot and need a mattress that ensures they don’t overheat while resting
  • People who have joint or muscle pain and need to ensure that their pressure points are soothed while they sleep
  • People who are light sleepers and have a partner who moves around a lot in their sleep

  • People who like a bounce in their mattress so that they can feel when they move around and find it easier to get out of bed
  • People who want a mattress that sinks when they lie on it and offers less in terms of support
  • People who don’t want their temperature controlled during sleep and would rather rely on their own natural body heat to regulate themselves

Summary of Our AS3 Amerisleep Review

This mattress has the perfect combination of firm support and luxurious comfort. You’ll be able to move around freely as you sleep without waking your bed partner or yourself. You’ll also receive superior support across all your body’s pressure points and will likely wake up without stiffness or pain due to sleeping heavily. The Amerisleep AS3 foam bed in a box is a great investment for a good night’s sleep.


Are Amerisleep mattresses good?

Yes, these mattresses are extremely well put together, using only the best materials. They’re made to last and offer superior comfort and support. They can be a bit on the pricey side, but that’s because each layer in these mattresses is made from top-quality materials with specially developed technologies.

Is Amerisleep better than Tempur-Pedic?

It depends on who you ask. Both brands offer a unique product that has both pros and cons. The Amerisleep AS3 is more affordable than the more high-end Tempur-Pedic products. We recommend going through the reviews of both these mattress brands before making a decision. 

How long do Amerisleep mattresses last?

The warranty on an Amerisleep mattress is 20 years, so you should expect the mattress to last for some time. This means you’ll be able to sleep comfortably on one of these mattresses for years and years before having to buy a new one.

Can you buy Amerisleep in stores?

There are dedicated Amerisleep retail stores situated in Arizona, Colorado, Oregon, and Texas. With multiple locations in each of these states, you can check out these showrooms and get a feel for the mattresses yourself. Alternatively, if you’re unable to get to a location in these states, you can easily make a purchase through the website without any hassles.

Which Amerisleep mattress is best?

This is the million-dollar question, and the answer is that it depends on you and how you sleep. We suggest in this Amerisleep AS3 review that you consider the AS3 as the best of both worlds. While you can get Amerisleep mattresses that are firmer and some that are more focused on comfort, this mattress gives you just enough of everything. It’s bound to please the most people with its many features and benefits.
