Amerisleep is one of the oldest mattress-in-a-box companies.
Founded in 2010, the company has set itself apart through high-quality mattresses, innovative features, and great customer service.
The company has been especially vocal about its efforts to be more environmentally friendly.
They have committed themselves to use eco-friendly materials and low impact manufacturing processes.
It is headquartered in Scottsdale, Arizona, Amerisleep ships its mattresses to customers living in the United States and Canada.
In addition to their online store, they also operate twelve brick and mortar stores in Arizona, Oregon, Colorado, and Texas.
Amerisleep is a step ahead of many other mattress companies when it comes to social responsibility, especially related to the environment.
Throughout its production chain, the company tries to stick to eco-friendly practices.
They go beyond standard requirements to create a product that is safe, high quality, and good for the environment – and their customers.
Additionally, all of Amerisleep's manufacturing is done in the United States, which provides opportunities to local workers. Keeping manufacturing in the US also goes a long way in ensuring that the highest manufacturing and environmental standards are maintained.
The company also works with local charities to provide beds to the less fortunate.
There are two places online where you can buy an Amerisleep mattress: on their official website at Amerisleep.com and Amazon.com.
The prices are usually the same on both sites. From time to time, though, you can find slightly-used mattresses on Amazon at a discount.
The most important step in the purchase process is to select your model, which determines the firmness level.
There are five mattresses to choose from, starting from AS1 through to AS5. For AS2, AS3 and AS5 mattresses, you can select between an all-foam version and a hybrid one with foam and pocket coils.
They all feature similar foam technology and construction, but differ in terms of firmness and a few advanced features:
- If you prefer a soft or medium-soft mattress, then go with the AS4 or AS5 mattress.
- For a firm or med-firm mattress, buy an AS1 or an AS2 mattress.
- If you are like 80% of sleepers today who prefer a medium feel, then go with Amerisleep's most popular mattress, the AS3.
- If you aren't sure, then Amerisleep's website will guide you to the best choice, based on your preferred sleeping position.
Once you make your model choice, you will be directed to the product page where you can learn more about the mattress, the trial period, read the Warranty, and choose your preferred size.
All standard sizes ranging from Twin to California King are available. All the models also offer a split King option.
Once you select a size, place your order.
Note: If you prefer to see and feel the mattress before you buy it, Amerisleep operates a dozen retail stores in four states. Here are the addresses.
FedEx shipping is free of charge within the United States.
If you are ordering a mattress from Hawaii or Alaska, shipping fees will apply. Extra fees also apply for international orders.
You can track your order online, once it is on its way.
No special shipping options – expedited shipping, white-glove – are offered.
Once your order is processed, it will take about a week to get your mattress delivered to your home, depending on your location.
Amerisleep provides free curbside delivery via FedEx anywhere within the United States.
Like other online memory foam mattresses, Amerisleep's mattresses are delivered to your home compressed and rolled into a thin plastic tube, packed 3 to a box on the truck.
Unpacking is simple: just cut the plastic wrap lengthwise and let her rip.
It takes about a day for the mattress to expand all the way, and another 1-2 weeks for the mattress to settle in completely.
Note that Amerisleep does not offer special delivery options. They only deliver to your curb.
All Amerisleep mattresses have a simple and sleek two-tone white and blue styling.
The cover is smooth at the top but transitions to a mesh design on the sides. The mesh paneling is not just for aesthetics; it enhances ventilation and cooling.
Advanced Memory Foam Technology
To offer a great sleeping experience, Amerisleep uses several advanced memory foam technologies to craft their mattresses.
The biggest challenge Amerisleep claims to have overcome is in turning memory foam – notorious for poor support and sleeping too hot – into a far more comfortable, bio-friendly material that fosters better sleep.
1. Variable Pressure Foaming
The memory foams used in Amerisleep mattresses are manufactured using a process called Variable Pressure Foaming or simply VPF.
VPF is a highly eco-friendly manufacturing process.
The mattresses are placed together in a specialized chamber, and any emissions are passed through carbon filters to remove pollutants before they are released.
Additionally, no harsh chemicals are used in the manufacturing process, and there are minimal volatile organic compounds (VOCs) in the foam.
All waste at the end of the process is recycled.
2. Bio-Pur memory foam
Ordinary memory foams, while plush and comfortable, tend to get too hot at night and may not offer the best support.
Amerisleep has formulated their memory foam to eliminate these downsides and to add a few more beneficial features.
The result is a slightly different type of foam called Bio-Pur.
Amerisleep calls their foam, ‘Bio' because some of the petroleum components of standard memory foam have been replaced with plant-based materials. This makes for a better, more comfortable, and far more eco-friendly mattress.
Bio-Pur foam is also a bit firmer and more resilient than first-generation memory foam, which provides better support.
Finally, Bio-Pur foam is more breathable than ordinary memory foam. It features an open cell structure that allows air to move freely within. This keeps the mattress cool, dry, and smelling fresh.
Amerisleep's AS1, AS2, and AS3 mattresses are made with the original Bio-Pur foam, while AS4 and AS5 utilize an updated variant called Bio-Pur+.
Bio-Pur+ provides better air circulation and cooling ability. According to the company, it has 70% more breathability than the standard Bio-Pur memory foam.
In addition to its open cell structure, Bio-Pur+ foam undergoes an extra process called reticulation. This removes remaining air-blocking membranes from the foam, which boosts airflow within the mattress.
3. Active Flex foam
This is another special foam formulation created to provide better responsiveness and support to the body.
It is used in the AS5 mattress only.
4. Zoned Support System (HIVE)
All the mattresses, apart from AS1, have a HIVE transition layer. This layer features channels cut into the mattress, which boosts airflow and cooling.
These channels are separated by raised foam hexagons that are grouped into five zones of variable firmness.
These zones correspond to different sections of your body: head, shoulder & back, hips, upper legs & knee, and lower legs.
The idea is to allow your body to sink where it needs extra pressure relief (the softer zones such as under the hips) and stay aligned where it needs support.
The zoned construction provides customized comfort since the mattress can easily adjust to your specific sleeping position and body weight.
All Amerisleep mattresses are memory foam. But the company recently introduced hybrid versions of their AS2, AS3, and AS5 mattresses.
The hybrid models replace the high-density foam in the all-foam versions with a 7″ pocket coil base encased in foam.
This is the firmest of the Amerisleep mattresses. This 10-inch foam mattress is ideal for back and stomach sleepers and consists of two main layers designed to achieve a firmer than usual feel.
Bio-Pur foam (2″ comfort layer)
The open cell structure of Bio-Pur makes it several times more breathable than standard memory foam and better at adapting to the body for increased support.
Bio-Core foam (8″ support layer)
The high-density Bio-Core foam provides support to the sleeper as well as the mattress. It also plays a crucial role in preventing uncomfortable (and unsightly) sags and ensuring that the mattress lasts a long time.
The AS2 is also on the firmer side of the scale but has a medium-firm feel.
It is a good choice for back and stomach sleepers who love a firm surface but with a bit of ‘hug' to keep them in position.
To create the medium-firm feel, the engineers made AS2 slightly thicker than AS1.
At 12 inches thick, the AS2 mattress has three layers.
Bio-Pur foam (2″ comfort layer)
A layer of eco-friendly memory foam provides pressure relief, comfort, and cooling.
HIVE transition layer (3″)
Zoned foam provides targeted support and pressure relief. Channels cut into the foam also improve breathability and heat dissipation.
Bio-Core foam (7″ support layer)
The sturdy, dense foam foundation resists sagging through the years. The hybrid version contains foam-encased pocket coils in the base.
The AS3 is their most popular model and the one we tested at home.
It measures 12 inches in thickness and is designed mostly for side and combo (all sleep positions) sleepers.
Bio-Pur foam (3″ comfort layer)
This layer forms the first line of comfort for the sleeper. It provides pressure relief as the plant-based foam adapts to your body contours and weight. Any heat and sweat generated by your body are quickly whisked away, thanks to superior airflow.
HIVE Transition Layer (2″)
This additional foam layer offers both firm support and soft comfort precisely where you need them.
Bio-Core foam (7″ support layer)
This high-density foam provides a sturdy foundation that prevents sagging by offering compression support. It also gives the mattress added durability.
If you want extra bounce and more robust support, get the hybrid version. Instead of Bio-Core foam, it contains foam-encased pocket coils in the base.
Moving over to the softer end of the spectrum, the AS4 mattress is designed to provide a medium-soft feel.
Buy it if you are a side sleeper who loves a plush, cushion effect on your mattress.
Stay away from this one if you hate sinking into a mattress.
The AS4 mattress is 12 inches thick and consists of three foam layers plus additional ventilation.
The AS4 mattress does not have a hybrid variant.
Bio-Pur+ memory foam (2″ comfort layer)
This layer uses Bio-Pur+, the upgraded version of Bio-Pur foam, that is even more breathable and adapts well to your body.
The extra-thick comfort layer gives the mattress a softer and plusher feel.
HIVE transition layer (1″)
Zoned foam provides targeted support and comfort while channels efficiently move heat out of the mattress.
Bio-Core foam (7″ foundation layer)
This plant-based support foam provides overall support to the mattress while remaining breathable.
This is the softest, thickest, and most expensive Amerisleep mattress.
It is a luxury-sized 14 inches thick and relies on four foam layers.
Bio-Pur+ memory foam (3″ comfort layer)
A layer of Bio-Pur+ foam provides superior cooling capability without too much support, leaving the mattress surface cool and soft.
Active Flex Layer (2″ response layer)
Active Flex foam improves the ability of the mattress to adapt and respond to your body. It keeps the mattress soft while also providing support and responsiveness.
The Active Flex layer easily contours to your body when you lie down and responds quickly when you shift positions. This ensures you don't get that ‘stuck in the mattress' feel that's common with luxury plush mattresses.
The AS5 is the only Amerisleep mattress to have this layer.
HIVE transition layer (2″)
A zoned layer provides targeted support and pressure relief to specific areas of your body.
Bio-Core foam (7″ support layer)
This thick, dense foam layer provides support for the sleeper and helps the mattress last years
For heavier sleepers and those who prefer a bouncy mattress, we recommend the AS5h, the hybrid variant of AS5. A pocket coil base improves responsiveness and deep compression support.
The cover is another major area of innovation for Amerisleep.
Amerisleep uses a special type of fabric, Celliant, to craft all of their mattress covers.
Celliant is a special yarn containing 13 Thermo-reactive minerals that react to heat uniquely.
When you sleep on a mattress, your body generates heat. A good mattress cover will absorb this heat (if they have poor airflow) and/or release it (if they have good airflow).
But Celliant does something radically different: it transforms your body heat into infrared radiation, which escapes quietly from your bed.
In addition to dissipating heat, infrared light has been found to have several health benefits. It boosts blood circulation, improves rest, increases energy levels, and helps to regulate body temperature.
With a Celliant cover on top, Amerisleep says you'll enjoy a deeper and better sleep and wake up feeling healthier, happier, and more energized.
The other online mattress I know of that uses Celliant technology is the Bear mattress, which was designed specifically for athletes.
There is one problem that most foam mattresses share: They usually emit a slightly unpleasant smell when they are fresh off the factory line.
Unlike years ago, however, when store-bought mattresses emitted harmful VOCs (volatile organic compounds), the smell you may experience when you first open your Amerisleep mattress is not harmful at all.
Remember that Amerisleep mattresses are Certi-PUR certified, which means they are made without harmful components like ozone depleters and heavy metals.
The company also uses plant-based materials to replace some of its petroleum-based components in the mattress, which reduces off-gassing.
Additionally, they use a special GREENGUARD certified fire sock for fire protection all around the mattress.
These technologies do not eliminate off-gassing, however.
Some Amerisleep customers have complained of an unpleasant odor from their new mattress. Others say they smell nothing but a ‘new car' smell. To each his own, I guess…
I noticed a slight ‘plastic-in-my-car' smell, too.
If you feel the smell is particularly strong, the company advises that you air-out the mattress for a few days. This means leaving it uncovered in a well-ventilated room such as the garage.
Don't make this your only deciding factor; however: it was barely noticeable after a day, and the smell dissipates completely within a week or so.
Eric and I could not sleep on every one of Amerisleep's 5 mattresses in our home.
We tested the medium-firm mattress, the AS3 (formerly called Liberty).
That said, if you look around the web at other buyers' reviews of the other Amerisleep products, you'll see that their experience has been generally positive.
The mattress we tested was very comfortable. It slept cool and offered a surprising amount of support for a memory foam mattress.
Because Amerisleep's products vary so much, it is important to look at the sleeping experience of each one of them separately rather than giving a blanket description.
Click on a tab below to learn more about each mattress's sleeping experience.
With the AS1 mattress – the firmest of the bunch – there are two kinds of sleeping experiences buyers are reporting.
For people looking for just a firm mattress, the AS1 was often too firm for their liking.
But for those with back problems, AS1 seems to be a great choice.
Even if you are just looking for a firmer mattress, this one could prove firmer than you want.
This is the most popular firm, Amerisleep mattress. It is on the firmer end of the scale, but not as extreme as As1.
The AS2 sleeping experience seems to be great for back and stomach sleepers, according to other reviewers.
As you would expect, the reported sinkage is minimal.
The softcover and the top Bio-Pur foam layer help create a soft cushion to balance out the extra firmness of the mattress.
This is the most popular Amerisleep mattress sold today.
The AS3 falls right in the sweet spot of firmness: not too hard and not too soft.
This makes it ideal for a wide variety of sleepers and is especially great for those who cannot sleep in a single position.
The sinkage is minimal: it's deep enough to create a slight cozy ‘hug' around my body contours but not so much that I can't move around at will (which I do a lot of).
The main complaint that other reviewers and I have about the AS3 is its relatively poor edge support. The AS3 does not hold up that well when you sleep or sit near the edge.
This is the same problem the Purple Mattress suffers from if you're comparing the two. The AS3 isn't as bad as Purple, but poor edge support can be a problem for couples and people who roll onto the edges of their bed at night (really active sleepers).
With the AS4, we start moving into the soft extreme of the firmness scale.
The AS4 mattress falls somewhere just behind Liberty on an increasing scale of firmness.
The combination of Bio-Pur+ memory foam and an Affinity Transition layer gives this mattress more sinkage than usual.
This mattress is perfect for slim sleepers with sharp body contours and side sleepers who need more cushioning for their shoulders and hips.
You might think this mattress is too soft for most people, but honestly, most people who've reviewed this mattress are pleasantly surprised by the firm support, despite the greater sinkage.
My only concern is whether this mattress is durable enough to last years without any damage. Soft foam mattresses are notorious for short lives.
To be fair, this is a concern with all-new online mattress brands. Because they have been around for just a short amount of time, we have no option but to wait and see whether their decades-long durability promises hold up.
The AS5 is the softest mattress Amerisleep has to offer.
Despite what you may think, AS5 does not feel like you're stuck in the mud at night. According to most reviewers, it still has a nice bounce to it. However, the sinkage on this mattress is more pronounced than the others.
AS5 is ideal for side sleepers and those who love a plush sleeping experience. Some say it is similar to those luxurious hotel mattresses that you sink into after a long trip.
Surprisingly, many reviewers claim the AS5 has better edge support than the slightly firmer AS4 mattress, although not as good as most innerspring & latex mattresses.
Given its level of softness, not many people buy it.
Like the AS4, AS5 is also a new product, which always raises the question of durability, especially for a very soft mattress. Will it sag too quickly? Will support deteriorate?
At this point, you'll just have to trust their Warranty (which, at 20 years, is outstanding).
I've kind of covered the different firmness levels in the section above (Sleeping Experience), but let's put some numbers on this, shall we?
If one represents very soft and 10 represents very firm, then…
- The AS1, the firmest option, rates a 7.5 out of 10
- AS2, the medium-firm option, has a firmness rating of 6.5
- The most popular option, the AS3, rates a slightly softer 5.5
- The AS4 is about a 4.0
- The softest Amerisleep option, the AS5, rates a 3.5 out of 10
We tested the AS3. The sinkage is minimal – noticeably less than most other memory foam mattresses I've tried. I found it easier to shift around at night.
AS1 and AS2 show the least sinkage when you lie on them.
AS4 and AS5 have the greatest sinkage due to their softness.
Edge support, or how well a mattress retains its support and structure near the edges of the bed. Strong edge support keeps you from rolling out of bed at night.
I found edge support lacking on the AS3 mattress we tested. Though I didn't test the hybrid version, it is bound to have better edge support because of the robust pocket coil base.
By creating a foam with better cooling and support capabilities than standard memory foam, Amerisleep has also created a sleeping surface that is excellent at inhibiting motion at the surface.
Motion transfer is essentially nonexistent on our Amerisleep mattress. Other reviewers say the same.
This is great news for couples. You can turn over all you want at night or wake up in the middle of the night without worrying that you will wake up your partner.
If you look at reviews of their other models, you'll see this is a common feature of all Amerisleep mattresses.
This is another area where our Amerisleep AS3 mattress earns a high rating.
The choice of plant-based foam textured channels, and using open-cell foam has created a mattress with virtually no hot/cold issues.
With its superior airflow, our AS3 mattress stayed cool, dry, and cozy. Don't worry about having to invest in additional toppers and pads to keep the heat out.
That said, a small handful of reviewers claim this mattress sleeps hot. But I didn't experience that, at all.
Generally, Amerisleep's eco-friendly mattresses are pricier than traditional online memory foam mattresses.
But compared with store-bought eco-friendly foam mattresses, they are a steal.

Listed below are the retail prices for their five mattresses.
NOTE: due to discounts, Amerisleep mattress prices are often $100-500 cheaper on their main site.
Note that their softer mattresses are far more expensive.
Amerisleep provides an exceptionally generous 20-year warranty on all of their mattresses.
During the first ten years, the company promises to replace or repair the mattress at no cost to you. This is non-transferrable, and the mattress has to be properly supported and used. Material and workmanship defects are covered.
During the final ten years of the warranty period, the mattress is covered based on a pro-rated schedule. If the mattress needs to be replaced or repaired, you will be assessed a charge against your refund with the amount depending on the number of years you have owned the mattress and its original purchase price.
As always, make sure you read their Warranty before buying.
Amerisleep's return policy states that you have 100 nights to test the mattress and decide whether they need to return it.
The company recommends you try the mattress for a minimum of 30 nights to allow your body to adjust to it.
If you still do not like it – maybe it is too firm or too soft – then contact the company to kick start the return process.
The mattress will be picked up from your home free of charge and either recycled or given to charity.
A full refund will be provided.
If you prefer exchanging the returned mattress with a softer or firmer one, then contact the company to arrange it.
Note: The trial and return policies are similar, whether you buy from Amerisleep's official website or one of their retail stores.
- Plenty of options to choose from.
- High quality, eco-friendly memory foams
- Excellent – surprisingly good – support
- Sleeps cool and dry
- Selecting the right mattress can be confusing.
- More expensive than other memory foam mattresses sold online
- No special shipping or delivery options
- A bit of off-gassing, but not bad.
Amerisleep is Perfect For You If…
- You're looking for the latest eco-friendly memory foam technology that sleeps cool and dry, with a little extra support
- You need a very specific comfort level
- You and your partner prefer different comfort levels (Split King option)
Although we only had the opportunity to review the AS3 mattress, I have to say that the sleeping experience was noticeably better than Casper or other traditional memory foam mattresses.
That said, if you need a softer or firmer mattress than these other guys offer, then you can't go wrong buying an Amerisleep mattress.
