The zoned polyfoam layer is slightly softer than in the AS2. If you’re lightweight, you’ll sleep just fine and feel supported on either version of the AS3. If you’re going to share your bed with a partner and need to use the entire surface area of the mattress then edge support is something you are going to want to take a look at. If you’re average weight, you may want to consider the hybrid AS3, whose coil system can discourage sagging around the lower back and hips. With a true medium firm feel, the AS3 is ideal for combo sleepers. On the image below pressure will be represented from blue (low pressure) to red (high pressure). This model is so popular because it’s built to suit all sleepers! The 3 inches of memory foam in the comfort layer provides good pressure relief and the poly foam layer below begins to provide some support while smoothly transitioning to the base, giving the mattress a good medium feel. In this position I could feel the foam layers begin to fill in the space beneath my lower back, which is good if you are a back sleeper. The base not only provides the AS3 with its shape but also gives the mattress some durability. The AS3 features construction aspects that are common in the Amerisleep line, such as Celliant covers, Bio-Pur foams, and SMT technology. Originally Sleepopolis started with mattress reviews, but we have big plans to expand going forward!

Cover – The cover for the AS3 is the same as all of the other mattresses in the Amerisleep line. The combination of the memory foam comfort layer and the poly foam below should provide a good mix of pressure relief and support. The 4 inch drop showed a small disturbance across the surface of the mattress. To start this test I lied down on my back with my weight pretty evenly distributed. Rather than giving just my opinion on the overall firmness level of the AS3, I brought in three other people to give their opinion as well. For this test I dropped a 10 lb steel ball from heights of 4 inches, 8 inches, and 12 inches and measured the disturbance on the other side of the mattress. The Amerisleep A3 mattress comes with a 100-night sleep trial. I did compress the top of the mattress when I hung off the side of the bed a little, but I never felt insecure in my position on the mattress. This next test is my way of showing the intensity of motion that is detectable from one side of the mattress to the other.

I moved to my stomach and my weight was once again evenly distributed, leading to low pressure across my entire body. The comfort layer is 3” of open cell memory, providing pressure relief and contouring. I found the cover slightly cool to the touch thanks in part to the Celliant blended into the material. I should also point out that this layer has a convoluted design (like an egg crate) to create some airspace in the mattress for temperature regulation and cooling. The layers of the mattress consist of 3-inch layer of memory foam, a 2-inch layer of poly foam, and a 7 inch layer of high density poly foam. Looking for the mattress that can please almost any sleeper? The initial feeling when I pressed into the AS3 was of the memory foam comfort layer on top. We can help! As you can see in the results above the map shows low pressure across my entire body. This layer is firm to support the comfort and transition layers above as well as provide deep compression support to the sleeper on top of the mattress. These models range from very firm (AS1) to very soft (AS5). The AS3 is 12” deep and consists of three layers. The feeling I had when first lying on the mattress was a classic memory foam feel of initial firmness followed by sinking into the mattress. Along with this, the breathable cover and convoluted transition layer combine to provide more airflow through the mattress for better temperature control. This layer will allow the sleeper to sink into the mattress a bit for pressure relief and provide some contouring to the body. When I rolled onto my side near the edge of the AS3 I found that the mattress did a good job holding up under added pressure to the side. If you are going to share your bed with a partner, you will want to know what it will feel like when the other person gets into and out of bed or tosses and turns during the night. The Amerisleep AS3 is the average firmness option in the Amerisleep line, and the most popular. With a medium feel and a blend of proprietary foams and coils, sleepers should experience the pressure relief and support they seek.
