Recommended For

The AS3 is an ideal mattress for three types of people:

  • Firstly, it is great for couples, people who share a bed with their loved ones. This is because the mattress has been built to withstand dreaded motion transfer.
  • The AS3 is a perfect fit for couples who shift around a lot during the night because it minimizes the amount of movement you will feel when your partner is getting comfortable. There is nothing worse than a bed that shifts and turns as much as your spouse does. The AS3 does away with that issue.
  • The AS3 is also a perfect fit for sleepers who like to enjoy a variety of positions throughout the night. Some people sleep on their stomachs, some sleep on their backs or their sides. And some people sleep in a whole variety of ways during one night’s rest.

The AS3 has been crafted with specific focus on support and pressure relief.

That means that no matter how you sleep, the AS3 will have you covered and keep you feeling relaxed and settled all night long.

Feeling overheated while trying to sleep is one of the worst things you can experience. It makes you feel frustrated, upset and grumpy.

Thankfully the AS3 mattress from Amerisleep has the Bio-Pur material built into it.

Amerisleep’s Bio-Pur is a foam creation that has an open-cell structure.

This design allows air to flow smoothly and easily through the mattress, which will keep you cool all night long no matter what.

Construction Overview

The Amerisleep AS3 is a sturdy and full mattress that will fill your bed frame perfectly.

It comes in multiple sizes, ranging from a Twin (38” by 74”) to a California King (72” by 84”).

The bed also comes in two builds: the traditional AS3 is built with the Bio-Pur foam and all the other great features listed above.

However, there is also the AS3 H model.

This hybrid version of the bed comes with both the Bio-Pur foam and built-in pocket coils that provide more bounce and responsiveness.

Despite the extra spring in the AS3 H, the bed still minimizes motion transfer you still won’t wake your sleeping spouse if you move a lot during the night.

The bed totals 12 inches in height and has a soft polyester cover that sits atop the mattress.

The cover feels stretchy and flexible and will snap to form easily, meaning it won’t bunch up and make a mess under your sheets.

Layer One: Bio-Pur

Immediately beneath that cover is Amerisleep’s touted Bio-Pur memory foam.

This much-publicized creation is a 4-inch combination of both polyurethane foam and plant-based materials that stores less heat and creates a firm and absorbent comfort. Amerisleep says their Bio-Pur is more breathable than typical memory foam and remains resistant to mold, mildew and dust mites.

Layer Two: Coiled Springs

The bed also contains a series of small and supportive coiled springs to allow a little bit of bounce in the AS3, no matter which model you have purchased.

The springs give specific attention to the upper and lower back and shoulders and hips. These are the areas that most people complain about after waking from a night’s rest.

Layer Three: Firm support

Underneath all of that lays a 7-inch layer of foam that is firm and stable and creates a solid foundation for the rest of the mattress to sit.

Amerisleep takes great pride in the fact that they use eco-friendly materials on their mattresses and refuse to use degrading, unhealthy and harsh chemicals in the manufacturing of their mattresses, including the AS3.

Rating Breakdown

With so many elements in play, it is important to take a closer look at all the features that can make or break the AS3.

Let’s dig into all the things that will help you determine if you want to spend your money on the Amerisleep AS3.

From firmness and support to the all-important price-point, we have a lot to explore.



The Amerisleep AS3 has a definite interest in keeping things quite firm while you sleep.

It isn’t as firm as some mattresses on the market but it certainly isn’t a loose and soft bed either. As with all firm beds, it may take some getting used to if you are transitioning from an older, weakened mattress and box spring.

If you feel a few minor aches in your body after you receive your new AS3 do not panic, this is normal and will fade within a few days or weeks.

In the grand scheme of things, Amerisleep has hit a sweet spot of firmness: not too much and not too little. It is a bit more than right in the center of the spectrum and leans more on the extra stiff than the extra loose side of things.


The AS3 has Amerisleep’s Bio-Pur system built into it and it gives customers a responsive and supportive rest.

Bio-Pur zeroes in on painful pressure points and is made to specifically locate and tend to areas of the body that attract and garner the most aches and pains, like the shoulders and lower and upper back.

Support is something that Amerisleep takes very seriously and customers who purchase the AS3 have found that the support crafted in the mattress has led to more restful and comfortable sleep and mornings with far less discomfort.


Once again, the Bio-Pur system gives AS3 users a real treat when it comes to cooling.

The design of Bio-Pur is paramount in keeping you comfortable and not too hot during your rest.

The plant-based material is laid in an open-cell design that encourages and allows air to flow freely throughout the mattress.

The material has proven to be more breathable than all other memory foams on the market so you will begin to feel cooler during your nightly rest almost immediately.

Motion Isolation

Perhaps one of the most attractive features of the Amerisleep AS3 is its ability to limit motion transfer.

If you sleep with a partner, you know how tricky it can be if you move a lot during the night and they don’t. It feels like every shift of your body causes them to wake and that can lead to some heightened tension and uncomfortable mornings.

But the AS3 really has fantastic motion isolation.

The Bio-Pur foam, paired with the coils built into the frame, have created a bed that won’t be rocking and rolling when you turn over in bed throughout the night.

Two people can both enjoy their rest, even if one of them is moving around an awful lot.


Of course price plays a major part when purchasing a new mattress.

While this is a long term investment and one that never comes cheap, you still want to be financially smart when making your big buy.

So let’s break down how much each version of the AS3 will cost you:

  • Twin (38” x 74”): $804
  • Twin XL (38” x 80”): $839
  • Full (54” x 75”): $944
  • Queen (60” x 80”): $1,049
  • King (76” x 80”): $1,329
  • California King (72” x 84”): $1,329
  • Split King (38” x 80” – 2): $1,678

As you can see, the prices of the AS3 vary greatly but a typical Queen-sized bed will run you around a thousand dollars.

When compared to other mattresses on the market, that isn’t too bad. It certainly isn’t cheap but that isn’t surprising because buying a new bed is an expensive endeavor.

Thankfully, you get a lot of good features for the prices listed above. Yes, you are spending a lot for the mattress but you are also receiving a lot as well.

AS3 Mattress Review


Amerisleep provides free curbside shipping for anywhere in the contiguous US. Curbside shipping consists of a freight company taking the mattress directly to your home but does not allow for delivery drivers to bring the mattress inside so you need to be prepared to bring your mattress inside yourself. That is no easy task depending on the size of your selected mattress but the extra work you have to do is worth it because you are saving hundreds of dollars in shipping fees.

Delivery typically takes up to 7 business days and is sent via FedEx. The mattress will arrive in a manageable, compact box that is only slightly larger than a typical mini-fridge.

There are many features in the Amerisleep AS3 that you can find in other beds on the market.

But when it comes right down to it, the mattress succeeds incredibly well in the three elements listed above: price, comfort, and construction.

The price of the AS3 is very affordable, especially when you shop around and see what competitors are charging.

The comfort built into the AS3 is very impressive. Amerisleep has taken great lengths to create a bed that feels wonderfully comfortable no matter what type of sleeper you are.

The cutting-edge technology and construction that goes into the AS3 is also remarkable.

Their Bio-Pur memory foam is perhaps the most extraordinary foam that you can currently buy. The dual firmness and softness of the bed feels magical and the cooling factor of the materials provides even more comfort and turns your nightly sleep into a dream come true.

All of those features come together to create a bed that is really special. And Amerisleep’s commitment to customer service and their unheard-of 20-year warranty is just icing on the cake.
