Amerisleep AS4 vs Aslan 10" GEL Memory Foam

The AS4 is our medium-soft mattress. It offers plush comfort with targeted support that helps you sleep your best. Plus it stays cool all night, making it our most popular model with side sleepers.

The Aslan mattress is a medium-firm (comfortable, yet supportive) sleep system comprised of the latest in sleep technology.

Three layer construction:

• Bio-Pur® foam
• HIVE® transition layer
• Bio-Core® foam support layer
• Refresh Cooling Cover.

The Aslan Mattress is the result of 11+ years being involved specifically in the online mattress industry. Eleven hard, yet exciting years of designing, creating, and testing (at 3rd party labs) dozens of mattress prototypes and materials. It is the very best combination of the newest sleep technologies on the market offered at a very fair and sensible price. Three layers of state-of-the-art foam:

• 2" GEL Infused Phase Change Memory Foam
• 1.5" Next Generation Memory Foam
• 6.5" Active Suppot Foam.

Traditional memory foam is made from dense material, so it traps your body heat and can make you sweaty and uncomfortable while you're in bed - and who can sleep like that?
We developed our foam with an enhanced "open cell structure", which means there is more air space between the foam particles. That space wicks away heat while you sleep, and can keep you cooler and more comfortable.

You will only find high quality CertiPUR-US®, American made foam in our mattresses. Foam selected for the Aslan mattress is considered a specialty foam, very durable, and contains the latest visco-elastic and cooling technologies, like Phase Change Material (originally developed for space suits), GEL, and advanced air flow - features that are necessary to regulate sleeping temperature and help you be cooler at night.

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.
The HIVE® layer features hundreds of foam hexagons grouped into five comfort zones. Each zone is designed to provide extra cushion where you want it and support where you need it. That way your body gets the support it needs to stay properly aligned, so you can sleep your best.

Our foam has been pressure mapped to ensure the layers of foam perform well for all sleeping positions and body types.

The HIVE® transition layer has precision-cut channels that carry away even more heat and moisture. It's enough to make you feel like you're weightlessly resting on a cloud.
Amerisleep's Bio-Pur® material features an advanced-open cell design. This makes Bio-Pur® more breathable and responsive than memory foam, which will keep you cool and comfortable all night. Plus we make Bio-Pur® from partially plant-based sources using a zero-emission process. That means it's the most eco-friendly material of its kind.

Our top layer of memory foam combines 3 cooling technologies; phase change material, open-cell viscoelastic and beaded gel-foam technology - providing improved temperature regulation and reduced pressure points.

Bio-Pur® contours to your body to relieve pressure points and bounces back fast, so you won't feel "stuck" during the night.
Our HIVE® transition layer provides targeted support and pressure relief so you can sleep in perfect alignment. It gives your head, back, and legs more support, and your shoulders and hips more cushion.

The Next Generation Memory Foam provides a little bounce, quick rebound, and exceptional durability. This layer has a very high pressure relieving index and is the perfect transition (for all body types) to the Active Support foam.
The Active Support foam is a high quality, tried and true durable support foam that holds its physical properties over time and is designed to correctly align your spine for an ideal sleep position.

Refresh Cooling Cover
The Refresh Cover draws heat from your skin for a delightfully cool-to-the-touch feel. On average, your sleeping surface will stay 7 degrees cooler over an eight-hour night of rest compared to a traditional 100% polyester cover. This scientifically engineered fabric uses minerals to help convert your natural body heat into far infrared energy. This type of energy increases blood circulation to help speed up muscle recovery and improve quality of sleep.

The Aslan Mattress features a soft knit, breathable cover that is designed to prevent heat buildup in the mattress. It is made in the USA and does not contain chemical fire retardents. Spot clean only.
