Amerisleep AS3 Mattress Review

This mattress has a firmness and support level that we believe will suit a wide range of sleepers, which is one of the reasons we believe it is ideal for couples.

Unless you and your partner have very different sleeping positions, you should both be comfortable on this "middle ground" mattress. We also like how this bed has all of the best features of memory foam without the overheating and quicksand feeling that some memory foam mattresses have.

Keep reading to know how this mattress excels in different aspects you'd look for in your next mattress for the perfect night's sleep.

Consider Amerisleep AS3 mattress if

• You are a memory foam fan.
• You are a couple! Amerisleep AS3 is ideal for couples as it has the least motion transfer we have experienced so far.
• You like a medium-firm feel bed, which actually should suit the majority of sleepers.
• You like to sleep cool. Though Amerisleep AS3 is made of memory foam, it comes with a heat-wicking Refresh Cover - included free on every AS3.
• You are a side sleeper. This mattress has the maximum pain relief for side sleepers.

Avoid Amerisleep AS3 if

• You are a stomach sleeper. This mattress will not meet the needs of stomach sleepers as this group of sleepers require a firm mattress to prevent their hips from sinking too far into the bed.
• You like a very bouncy bed. In general any all-foam bed lacks this feature, and you should not expect to get the bounce you'd get from a spring mattress. If that's the case, we would suggest the Amerisleep AS3 Hybrid or one of our recommended best innerspring mattresses.

Now let's dive into more details and how exactly is the feel, comfort, and performance of this mattress was in our reviewing process experience.

Before we start the details of this review we would like to clarify that Amerisleep offers 5 models total, the AS1, AS2, AS3, AS4, and AS5, which are scaled from firmest (AS1) to softest (AS5). In our article here here we are reviewing their best-selling medium-firmness AS3 model.

Firmness, Feel and Comfort for Amerisleep Mattress

In general, the firmness of a mattress is measured using the scale from 1-10 shown in the chart below, with one being the softer mattress and 10 being the firmer mattress.

Amerisleep AS3 showed to have a sinking value of 6. After trying this bed for a while, our team also voted to rate it as a 6 out of 10 on the firmness scale, indicating that it is a medium-firm mattress.

This medium-firmness feel means that most sleepers will be comfortable with this mattress. It offers plenty of contouring and pressure relief while remaining supportive. One of the reasons we recommend this bed to couples is that it is likely to please both sleepers.

Sleeping on this mattress will make you feel more "in" than "on top" of this mattress, which means you'll experience some sinking.

This is something to keep in mind if you are a combination sleeper who frequently changes positions throughout the night — you may have some difficulty doing so on this bed.

Amerisleep AS3 Mattress Performance

This mattress may or may not be suitable for you, depending on your weight and preferred sleeping position. Check out some of our suggestions below.

Is the Amerisleep AS3 a Good Mattress for Light Sleepers (Under 130 lb)?

• Light Back Sleepers - Amerisleep AS3 is an excellent mattress for light back sleepers. It will provide the necessary support while also providing a warm hug. Light Side Sleepers - This mattress is extremely comfortable for light-side sleepers. It provides the body with enough sink in the hips and shoulders and keeps the spine straight.
• Light Stomach Sleepers - This bed is a little too soft for these people. We would recommend a firmer bed that will provide more support at the hips, which tend to sink in when sleeping on the stomach.

Is the Amerisleep AS3 a Good Mattress for Average Weight Sleepers (130 – 250 lb)?

• Average Weight Back Sleepers - We believe this mattress will be suitable for the majority of average weight back sleepers. If you have back pain, we would recommend one of our best mattresses for back pain, which have firmer or more localized support. Side Sleepers of Average Weight - These sleepers should be content with this mattress. It has good cushioning and should keep them comfortable.
• Stomach Sleepers of Average Weight - This bed is too soft for stomach sleepers of all body types. They require something with more solid support.

Is the Amerisleep AS3 a Good Mattress for Heavy Sleepers (over 250 lb)?

• Heavy Back Sleepers - This mattress might not be the best choice for this category. For heavier people we would recommend the AS4 Mattress, which has the most layers of any Amerisleep mattress. A taller mattress in general is better for larger people because it prevents them from sinking all the way to the bottom of the mattress. Heavy Side Sleepers - We would recommend the AS5 for these sleepers. It has the most layers and will provide these sleepers with some nice sinking and pressure relief.
• Sleepers with a large stomach - We don't believe any Amerisleep mattress will be suitable for these sleepers, who require a thick bed with plenty of firm support.

Amerisleep AS3 Mattress Pain Relief Performance

If you have pain, you'll want a mattress that relieves pressure at sensitive pressure points like the hips, shoulders, and lower back. We used a pressure mat to demonstrate how the AS3 relieves pain.

We placed this mat on top of the mattress and then one of our team lied down on it. The mat recorded how much pressure their body exerted as they moved around in various positions.

Points of low pressure are shown on the map in blue to green colors, and points of high pressure are shown on the map in yellow to red colors.

Back Pain relief - As you can see, the map is completely blue, which means the body weight was distributed evenly. We have to point out that the team member who tested this mattress was a light-weight sleeper. Shoulder Pain relief - We believe that this is a good mattress for shoulder pain. Because they cushion joints, memory foam mattresses like this one are excellent for shoulder pain.

Hip Pain relief - We liked this mattress for hip pain, especially if you are a light weight sleeper. If you're an average or heavy sleeper who suffers from hip pain, you might want to consider the plusher AS4 or even AS5.

Motion Transfer

Whether you are a couple or you are sleeping alone, motion transfer is an essential characteristic in any mattress, especially if you are a light sleeper or suffer from insomnia and might get irritated by the slightest movement during sleeping even if it is your own. In this part of our review we tested the Amerisleep Mattress performance for motion transfer by using a 10 lb steel ball on the mattress and measuring the wave transmission by a seismometer.

Amerisleep AS3 mattress showed a great motion transfer results,which means that you’re unlikely to feel your partner’s movements or yours at night, which is a great feature for memory foam beds like this one.

Performance during Sex

This motion transfer feature might be great for sleeping but not so great during sex, as usually people prefer a more bouncy mattress for this purpose. We would say that Amerisleep AS3 is good for sex since it does not cause the body to totally sink. However, if you're looking for a step-up in this department we would recommend choosing the Hybrid version of the AS3, the Amerisleep AS3 Hybrid.

Edge Support

The term "edge support" refers to whether the bed's edges are strong enough to support you when you roll toward them or sleep on the edge. Couples will want good edge support in order to spread out. Strong edges also contribute to overall durability by preventing premature sagging.

I believe the AS3 has adequate edge support. It's not the strongest I've seen, but I wouldn't be concerned about slipping off when lying on the bed's edges.

Construction and Design for Amerisleep AS3 Mattress

Layers

The Amerisleep AS3 is an all-foam mattress with a three layers and a height of 12 inches along with a breathable cover that comes with all Amerisleep Mattress models. The AS3 is a medium firmness mattress that is in the middle of the Amerisleep line.

The combination of the memory foam comfort layer and the poly foam beneath should offer an adequate combination of pressure relief and support. CertiPUR-US® Certified foams are used in all Amerisleep mattresses, ensuring that they are free of harmful chemicals and pollutants.

The three layers of Amerisleep AS3 Mattress are:

1. Cover. The Amerisleep AS3 Mattress comes with a plant-based Bio-Pur material cover that keeps you cool at night. We found that the mattress cover had a delightful cooling feeling and it reduces the heat feel that usually is sensed from a foam mattress. The company is advertising that this cover is made from a fiber with extremely high energy transfer capabilities, and over an eight-hour sleep cycle, your sleeping surface will stay 7 degrees cooler on average.
2. Comfort layer. This is the mattress top layer. It is made of 3 inches of Bio-Pur foam. As its name indicates, this layer is a "comforting" layer, that allows the body to sink into the mattress slightly for pressure relief and body contouring. Unlike the usual memory foam mattresses which causes over heating during night, the Amerisleep uses a foam with an open cell structure to help dissipate that heat and aid in cooling. It is also environmentally friendly material as it is made of plant-based materials, reducing the amount of petroleum used in the mattress's construction.
3. Transition Layer. A 2-inch HIVE transition layer sits beneath the comfort layer. This foam is firmer and serves as a transition layer between the soft memory foam above and the firm base below, as well as providing some bounce to the mattress so the sleeper does not feel stuck when adjusting their position. This layer also has a convoluted design (like a beehive) to create some airspace in the mattress for temperature regulation and cooling.
4. The base Layer. The mattress's foundation is made up of a 7-inch layer of Bio-Core foam. This high-density foam layer is firm enough to support the comfort and transition layers above while also providing deep compression support to the sleeper on top of the mattress. The base not only gives the AS3 its shape, but it also adds durability to the mattress.
