With so many options, finding an Amerisleep mattress to fit your sleep needs should be a breeze. We personally tested the AS3 and loved it! In this review we will discuss our experience with the AS3, as well as an overview of all 5 models. Our Amerisleep Mattress Review is designed to help you make an informed decision as to which model is right for you.

Cutting out the middleman

Like most bed-in-a-box companies, Amerisleep makes shopping for a mattress online easy and cost effective.  By cutting out the middleman, Amerisleep is able to offer top-quality products at a more competitive price than a tradition brick and mortar establishment by reducing overhead costs. Additionally, mattresses are delivered to your doorstep and include a generous sleep trial, allowing you to try out your new bed in the comfort of your own home, risk-free.

Amerisleep Shared Construction

With 5 firmness levels to choose from, how do you know what is right for you? All 5 Amerisleep models share some common construction features:

  • Celliant Cover: Celliant takes the natural heat from our body and converts it into infrared energy.  In addition to helping you regulate your body temperature, celliant increases blood flow and the oxygenation of cells to aid the body in maintenance and recovery.
  • Greenguard Fire Sock: Flame retardants are required in all mattresses, but not all are created equal.  Using a rayon fiber made from natural cellulose, the fire sock is designed to melt in the event of a fire, snuffing out the flames.  Being Greenguard certified you can rest assured that the fire sock has passed indoor air quality certification for low chemical emissions.
  • Bio-Pur Comfort Layer: Open-cell, plant based memory foam for body-contouring and temperature regulation.
  • Bio-Core Base Layer: Providing the foundation of support, this layer offers durability and helps prevent sagging over time.

Amerisleep categorizes its models into 2 collections: firm and soft. The firm collection includes the AS1 and the AS2.  In the soft collection you will find the AS3, AS4 and AS5. Let’s take a look at the differences.

AS1 - Firm

Amerisleep lists the AS1 as the firmest mattress in its lineup.  This makes it an excellent choice for back and stomach sleepers who require a bit more support to prevent mid-section sagging.  This model is not recommended for side sleepers and may not be suitable for combo sleeping.  The mattress stands at 10″ with an 8″ Bio-Core Base Layer and 2″ Bio-Pur Comfort Layer.

AS2 - Medium Firm

The AS2 stands at 12″ and is listed as a medium-firm feel. Also designed for back and stomach sleepers, this mattress may be a bit too firm for side and combo sleepers.  The AS2 has 3 layers which include:

  • 2″ Bio-Pur Comfort Layer
  • 3″ Affinity Layer with SMT.  This layer works as a transition between the comfort layer and the base layer, increasing the responsiveness and supportiveness of the mattress.  
  • 7″ Bio-Core Base Layer

AS3 - Medium

The AS3 comes in at medium on the firmness scale.  It’s the best of all worlds providing the contouring pressure relief for side sleepers and combo sleepers with the support needed for back and stomach sleepers.  At 12″ in height, the AS3 layers are as follows:

  • 3″ Bio-Pur Comfort Layer
  • 2″ Affinity Layer with SMT.
  • 7″ Bio-Core Base Layer

AS4 - Medium Soft

Queen starts at $1699

With a medium-soft feel this mattress is best for side sleepers and combo sleepers.  Back and stomach sleeper may need more support, particularly if on the heavier side. 12″ in height, the AS4 is constructed as follows:

  • 4″ Bio-Pur Comfort Layer
  • 1″ Affinity Layer with SMT
  • 7″ Bio-Core Base Layer

AS5 - Soft

The AS5 is the softest mattress in the lineup, as such we think it is best suited for strict side sleepers. Standing at 14″, the AS5 is the only mattress with 4 layers of foam, as follows:

  • 3″ Bio-Pur Comfort Layer
  • 2″ Active Flex Layer, this layer provides plenty of contouring and pressure-relief with a quick, responsive bounce.
  • 2″ Affinity Layer with SMT.
  • 7″ Bio-Core Base Layer

Firmness and Feel

We felt the AS3 came in around a 6.0 on the firmness scale.  When you first climb into bed you are definitely met with the soft, responsive feel of the comfort layer but as you settle into your sleep positions, the support of the base layer comes up to meet you.  The AS3 does a great job of providing contouring, pressure-relief while maintaining enough support to make this a great choice for all sleep positions and body types.  It has an all around versatile feel that works well whether you change position through the night or if you and your partner generally like different firmness settings.  

Will couples like the amerisleep aS3?

Motion transfer is important if you share your bed with a partner who tosses and turns or a pet that is in and out of bed. Memory foam mattresses tend to perform well in this category and the AS3 was no exception. Mike and I experienced little to no motion transfer, allowing us to sleep through the night without disturbance. This makes it a great choice for couples!

Edge Support

Edge support plays a significant role in how large your bed will feel.  With firmer edge support, the surface space of your mattress will feel larger. Conversely, if edge support is lacking, the mattress will likely feel smaller. Lying on the edge of the bed we felt the edge support was fairly good. Though there was a bit of compression, we did not feel as if we would tumble off the bed.  Sitting on the edge of the bed was another story, in this position the edge support compressed quite a bit.

Will Amerisleep sleep Hot?

Memory foam has a reputation for running hot and as such can be off-putting.  However, Amerisleep uses an open cell structure that allows for more breathability. Combined with the celliant cover, we found Amerisleep to be one of the coolest mattresses we have slept on, quite literally. We did not wake up sweating or overheating through the night.

Eco-Friendly

Amerisleep has designed a mattress that is not only comfortable, but eco-friendly.  Through a process called Variable Pressure Foaming (VPF) they are able to manufacture their foams with zero emissions, while also removing harmful chemicals in the air. While most foams are manufactured in the open, Amerisleep uses a closed chamber design which exceeds the requirements of the Clean Air Act. Additionally, they use plant-based materials in the construction of their foams, cutting down on petroleum usage.

Amerisleep AS3 Mattress Review Conclusion

The bottom line is that the Amerisleep is one of the best memory foam mattresses currently available on the market. Everyone has unique sleeping needs, which makes picking a mattress very subjective. The type of mattress that’s suitable for you depends upon your body type and the sleep position you prefer, among other factors.

To recap, Amerisleep is available in 5 different firmness options meaning, as a brand, you are sure to find a firmness setting to match your needs. If you sleep hot, or are looking for a performance recovery mattress, this could be the right choice for you. The celliant cover offers a wide range of benefits including increased oxygenation and blood flow and it’s also one of the coolest sleeping mattresses we have tested so far!
