The Amerisleep AS3 is one of the most popular models by Amerisleep. This mattress has a medium feel that contours very well but still offers enough support for stomach and back sleepers. What sets Amerisleep mattresses apart from most of the competition is that all their models come with Celliant® technology infused into the cover. Celliant® is a proprietary mix of 13 thermo-reactive minerals that are embedded into polyester fibers. This fiber absorbs body heat and recycles it into infrared energy. The benefit of this technology is increased circulation, which leads to better sleep and recovery.
The medium firmness of the AS3 makes it ideal for most sleep positions and body types. Side, back, stomach, and combination sleepers are sure to find comfort with this bed. Amerisleep has also released the AS3 in a hybrid version. The AS3h hybrid offers the same responsive and soft Bio-Pur® comfort layer, but the base of the hybrid is individually wrapped innerspring coils that are zoned for targeted support. The hybrid is a great option for those that want the contouring effect of memory foam, but also like the bounce that comes with an innerspring bed.
Now, let’s look at the details of the Amerisleep AS3 and jump into my review!
Here’s a pic of the mattress roll packed inside the box.
Here’s the mattress on the bed.
Finally, this is what it looks like a few minutes after opening it. As you can see it is already at full shape.
Here’s a video overview of the AS3. This mattress recovers quickly out of the box and had little off-gassing smell. This mattress comes with a standard 100-night trial with free shipping and free returns.
Below are the prices of the mattress as of this writing.
Here’s another view from the side of the mattress.
It’s a minor detail but in my mind, it matters. The zipper system on this mattress is high quality. It’s easy to unzip and the zipper is actually in the middle so you don’t have to lift up the mattress to access it.
Here’s a picture of the layers of the mattress. Below the blue cover that you see above, there is a fire sock. I removed part of the fire sock to show you these layers. Again, these are cut clean. Some mattresses I have opened are warped towards the corners and don’t fully recover due to the use of too much glue.
Amerisleep uses a plant-based foam in their mattresses to lessen the environmental impact. I’m not sure the exact ratio but it is certainly nice to learn that they are trying to move the needle in the right direction. The foam is an open-cell foam which means more breathability too. This mattress feels amazing and is breathable for an all foam mattress.
Here’s a clip showing motion transfer on the mattress which is basically none because it is a foam mattress.
Here’s a video showing the inside layers of the AS3 and how each reacts. The top layer is a little slower to recover because it provides the most contouring and pressure relief. The recovery is faster than most dense foam mattresses but not quite as fast of a recovery as something like an Avena foam. Basically, you won’t get that stuck feeling and the mattress is really easy to move around on.
Overview of the Amerisleep AS3
After you place your order, your Amerisleep mattress will arrive at your door in a box like the one below. No need to wait for a delivery company.

Construction of the Amerisleep AS3
Below are the construction details as listed on their website.
HIGH-PERFORMANCE CELLIANT® COVER
Celliant® is an advanced fabric made with 13 thermoreactive minerals that helps improve the performance of the mattress.
EXTRA-BREATHABLE COOLING LAYER
Our Bio-Pur™ foam is five times more breathable than traditional memory foam, because of it’s advanced open-cell structure. It wicks away heat while you sleep and can help keep you cool and comfortable.
“FEELS-LIKE-YOU’RE-FLOATING” LAYER
The affinity transition layer is soft and responsive. It reacts to your body position to evenly support your weight and can help relieve pressure points, so it feels as if you’re weightlessly resting on a cloud.
SAG-FREE & ECO-FRIENDLY SUPPORT
Our Bio-Core™ foam support layer won’t sag even after decades of use. And, like our Bio-Pur™ foam, it’s partially made from plants instead of petroleum so it’s eco-friendly.
