Serta iComfortECO Foam vs Amerisleep AS3

The base model (CF1000) is a medium comfort. Choose the cooling upgrade (CF2000) model if you prefer a firm feel. Both the Max Cooling Upgrade (CF3000) and Max Cooling & Pressure Relief Upgrades (CF4000) offer a selection of feels - medium, plush, ultra plush and firm, plush, ultra plush.

The AS3 is our most versatile mattress. It evenly blends support and softness, so it's great for people who change positions as they sleep and couples with different sleep styles. It's also our most popular mattress overall.

With the iComfort by Serta® mattress, cool, supportive sleep is the priority. The base model (CF1000) has these layers:

• Carbon Fiber Memory Foam
• EverCool® Fuze Gel Foam.

Three upgrades are available at additional cost.

The AS3 is Amerisleep best-selling mattress. It's tailored to adapt to most body types and sleep styles. Its perfect “medium” feel uses an even mix of comfort and support to relieve pain-causing pressure points and support healthy sleeping positions. Three layer construction:

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

Specifically designed mattress to keep even the warmest of sleepers cool. You don't have to be a hot sleeper to love iComfort. You just have to like your sleep environment to be refreshingly comfy. Three cooling upgrades available:

• Cooling Upgrade (CF2000): 11.5" Additional cooling and firmer support.
• Max Cooling Upgrade (CF3000): 12.5" Cooler and more breathable.
• Max Cooling & Pressure Relief Upgrade (CF4000): 13.5" Feels and sleeps cooler, with air support layer to take pressure off joints.

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.

Multi-layered foam technology adds support, resilience, and temperature regulation for the coolest, most comfortable sleep ever.

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.

Every iComfort mattress is made with our exclusive Carbon Fiber Memory Foam. This system channels heat away from your body.
Gel Active® Max Foam (used only in CF2000 model) is an open celled memory foam helps promote airflow, so you don't have that hot, stuffy feeling when falling asleep.
UltraCold System™ (used in the CF3000 and CF4000 models) The layer of extra-cool Carbon Fiber Memory Foam is engineered to work hard at absorbing excess heat from your body, then channel it away, all while you sleep comfortably.

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.

Carbon Fiber Memory Foam provides exceptional strength for back and neck support.
Air Support™ Foam (used only in CF4000 model) moves with your body and contours around it to help alleviate aches and pains caused by 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.

A Max Cold™ Cover is used in the CF3000 and CF4000 models. Made from super cool high-performance fibers for an instant cool-to-the-touch sensation.

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.
