Like the name says, an all-foam mattress is made exclusively from layers of foam. Overall, they’re a better choice for someone who likes a more “absorbent” feel that conforms to your body.
Foam conforms to your body for a more absorbent feel.
Bio-Pur® foam features an open-cell structure to wick away warm air and keep you cool.
HIVE® technology offers five targeted comfort zones. Your head, back, and legs get more support. Your hips and shoulders get more cushion.
The absorbent feel of an all-foam mattress provides the least possible motion transfer.
A hybrid mattress combines layers of foam with a pocket-coil spring base. Overall they’re a better choice for someone who likes a mattress with more bounce and responsiveness.
Springs add more lift and bounce beneath the contouring foam top.
Pocket-coil springs add even more cooling airflow under the breathable Bio-Pur® top layer.
Firm coil edges and hundreds of responsive pocketed springs in the center deliver advanced support and responsiveness.
High-density pocket-coil springs help minimize motion transfer.

The surface you sleep on is incredibly important to your comfort. That’s why we developed the Refresh Cover for our mattresses.
Because it’s made from a fiber with extremely high energy transfer capabilities, the Refresh Cover draws heat from your skin for a delightfully cool-to-the-touch feel. On average, your sleeping surface will stay 7 degrees cooler over an eight-hour night of rest.*
Plus, our plant-based Bio-Pur material keeps you cool all night. Its open-cell design allows more air to circulate than traditional foam — and more airflow means cooler sleep, less sweating, and no more tossing and turning.
*Compared to a traditional 100% polyester cover.
Along with keeping you cool, the Refresh Cover also supports improved daily performance and energy. This scientifically engineered fabric uses minerals to help convert your natural body heat into far infrared energy.
Why far infrared? This type of energy increases blood circulation to help speed up muscle recovery and improve quality of sleep. Plus, according to peer-reviewed medical studies, far infrared exposure may offer even more health benefits than we even know about yet!*
Our plant-based Bio-Pur® material keeps you cool all night. It features an open-cell design that allows more air to escape than traditional foam.
Open-cell design wicks away warm air
More breathable than traditional foam
Bio-Pur® is the perfect answer to a better bed. Available in every Amerisleep mattress, we engineered Bio-Pur® to deliver cooling comfort, responsive support, and healthier sleep.
Memory foam lovers say Bio-Pur® is a huge upgrade, while critics admit it solves all the problems of traditional memory foam. Plus, since our beginnings in 2009, we've proudly manufactured Bio-Pur® in the USA.
Bio-Pur®'s large, open-cell structure has a few distinct advantages:

to dust mites, mold, and mildew & made without harsh chemicalsTraditional memory foams miss the mark when it comes to cooling and responsiveness. Amerisleep’s proprietary Bio-Pur® memory foam is an eco-friendly alternative that blends contouring comfort with buoyant support and superior breathability to help you get your best night’s sleep yet.
Our plant-based Bio-Pur® is significantly more breathable and responsive than traditional memory foam. It snaps back to its original shape in seconds, so it’ll never cause you to uncomfortably sink, and it’s significantly more porous and airy, so you won’t have to worry about night sweats. Even better? Bio-Pur® contains a fraction of the petrochemicals used in other memory foams, so it’s less likely to off-gas and is completely free of harmful substances.
That’s why in over 15,000 reviews, our mattresses rate 4.7 out of 5 stars and why 98% of customers would recommend us to a friend.
Our Bio-Pur® comfort layer contours to your body and relieves pain-causing pressure points. But it also bounces back fast, so you never feel “stuck” if you move around at night.

Amerisleep Mattresses come with free shipping within the continental US. We ship our mattresses direct to your home and compressed in an eco-friendly box using FedEx. And in most cases, they arrive in two weeks or less.
Please note: All our products ship separately, so if you’ve ordered a foundation, base, sheets, or any other sleep accessories to go with your new mattress, they may arrive sooner or later than your Amerisleep mattress. But don’t worry, shipping is always free.
Amerisleep mattresses are backed by an industry-leading 20-year warranty. For the first 10 years, we will replace your mattress if you encounter any defects, including sagging greater than 1”. And for the second 10 years, we will offer you a prorated replacement.
Our mattresses are compatible with a variety of bed frames and bases.
Mattress Foundations
Our memory foam and hybrid mattresses are best supported on solid or slatted mattress foundations. We offer a variety of bed bases which are all compatible with our mattresses. Non-Amerisleep foundations, however, should have slats no more than 2.75 inches apart.
Platform Beds
Platform beds have a solid or slatted base, so they can provide proper support for our mattresses. If you have a platform bed with large gaps between slats that was not designed by Amerisleep, we suggest buying extra slats or a bunkie board to create a sturdier surface for your mattress and meet warranty guidelines.
Adjustable Bed Frames
Both our memory foam and hybrid mattresses work well with adjustable bed frames. They’re adaptable and flexible, so they can move with the base without becoming damaged or worn. We even sell two adjustable bed frames to pair with our beds: the Amerisleep Adjustable Bed and the Amerisleep Adjustable Bed+.
While our mattresses can work with most bed frames and foundations, it’s not compatible with absolutely every type of mattress support — namely box springs.
Box Springs
Box springs are best paired with innerspring mattresses, and since innerspring beds were the most common for many years, a lot of us have box springs at home. Box springs contain coils within and as a result, are bouncy. Beds with foam layers can experience premature wear, tear, and unexpected damage when paired with one of these because they do not offer the even, sturdy support foam beds need.
If you intend to use an existing bed frame, please confirm dimensions & assembly options for your bedframe to ensure compatibility.

"We’re looking forward to having the AS3 for the rest of our lives."
The AS3 is our bestselling mattress. Its perfect “medium” feel balances an even mix of plush comfort and firm support, helping relieve painful pressure points while supporting full-body spinal alignment.
Sleepers of all body types and sleep styles rave over the AS3. And with two core options — the All-Foam and the Hybrid (coils) — you can choose the feel that’s right for you.
Sleep up to 7 degrees cooler throughout the night with our incredible heat-wicking Refresh Cover - included free on every AS3 Hybrid.
Whether you choose All-Foam or Hybrid, you’ll find the AS3 is the perfect “medium” feel mattress. With a mix of plush comfort and firm support, the AS3 is especially great for combo sleepers (AKA toss-and-turners) and couples.
As the closest part of the mattress to your body, the cover matters. Our Refresh Cover is designed to keep you up to 7 full degrees cooler (over an 8-hour night of rest) than competing all-foam mattresses.
Our plant-based proprietary foam layer helps you sleep cooler. And because it’s more responsive than traditional memory foam, it keeps you from feeling “stuck” in your mattress.
Our unique HIVE layer offers 5 zones of support and pressure relief for your head, back, legs, shoulders, and hips.
A long-lasting mattress starts with a great foundation. 6 inches of high-density support foam keeps your mattress from sagging, so you can enjoy great sleep for years to come.

These aren’t your grandma’s mattress springs. Individual pocket coils offer responsive support that conforms to your body and reduces motion transfer between partners — while also allowing airflow through the upper foam layers.
Wondering how Amerisleep stacks up? We’ve been winning awards and accolades from press reviewers and mattress experts for more than a decade.

Here’s how to choose between the All-Foam AS3 and the Hybrid AS3
Like the name says, an all-foam mattress is made exclusively from layers of foam.
Our Bio-Pur® foam is made with an open-cell structure that constantly draws warm air away from your body to keep you cool.
Plus, our HIVE® support technology targets five distinct comfort zones throughout your body. Give your head, back, and legs the support they need, while offering your hips and shoulders the cushion they’re craving.
A hybrid mattress combines layers of foam with a pocket-coil spring base.
Hundreds of high-density, pocket-coil springs add lift and bounce to your mattress, while minimizing motion transfer between you and your partner.
And on top? A generous layer of breathable, cooling Bio-Pur® foam to keep you sleeping cool and comfortable all night long.
And remember — your mattress is backed by our risk-free, 100-night trial.
Try your new Amerisleep mattress in your own home risk-free for 100 nights. If you don’t love it, our customer support team in Arizona will give you a fast and full refund. We’ll even help you schedule a pickup to recycle your returned mattress.
Amerisleep has been leading a sleep revolution for over a decade. We started by reinventing the the typical mattress buying experience. We were one of the first companies to sell mattresses online. And we also led the way with our risk-free, 100-night trial and 20-year warranty.
Plus, we did it without sacrificing quality. We proudly manufacture our mattresses right here in the USA. We also use plant-based and eco-friendly materials certified by CertiPUR-US®.
But we didn’t stop there. We also designed an entire suite of bedding products that creates a complete sleep system. Together, they deliver deeper rest and better recovery.
Our tester found it comfortable while snuggled up with blankets in a stuffy apartment.
I love how they cover all the bases and make it so they have a mattress option for almost every sleeper — even environmentally-friendly ones.
This model is newer to our testers, but so far it’s getting top-notch reviews.
All reviews are unaltered and verified by a 3rd party.
The AS3 model has a balanced feel suitable for the majority of sleepers. Side, back, and combination sleepers can all rest well and wake up feeling refreshed. This is why our AS3 mattress is our most popular model and why we recommend it for couples interested in sharing a bed.
Medium feel mattresses are almost universally comfortable. Side, back, and combination sleepers can usually rest well on medium mattresses. Couples with conflicting sleep styles, such as a side and back sleeper, can usually compromise with a medium feel mattress and still rest peacefully.
Yes, our AS3 mattress can provide comfort for plus-size sleepers. We recommend it for side and combination sleepers because of its delicate balance between cushion and support. Conversely, we don’t recommend it for plus-size stomach and back sleepers.
Heavyset back and stomach sleepers may sink too far into the AS3 mattress because of how their position distributes their bodyweight. A firmer feel can prevent sinkage, so we recommend our AS2 or AS1 mattress for stomach and back sleepers over 250 pounds.
Yes, the AS3 memory foam and hybrid models can help a side sleeper experiencing back pain rest well because the balanced feel cushions a side sleeper’s shoulders and hips while supporting the spine’s neutral alignment.
However, the AS3 mattress may not be right for back sleepers experiencing back pain. Back sleepers may find it feels too soft and allows their spine to bow too far into the mattress. For back sleepers, we recommend our AS2 mattress.
We cover structural or manufacturing defects, along with any sagging that exceeds 0.75 inches. Our warranty starts on the day a mattress is purchased and applies only to the original owner.
