Amerisleep AS1 vs Serta iComfortECO Smooth Hybrid

The AS1 is our firmest mattress, it offers gentle-but-firm support that stays cool all night. It's a great choice for back and stomach sleepers who like extra support.

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

Two layer construction:

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

The Serta iComfortECO Smooth Hybrid is a hybrid mattress best suited for side sleepers. The materials used are up to 70% sustainable.

It has a layer of 5-Zone Quad Coil for support and targeted pressure relief. And two layer of memory foam that's breathable and provides reduced motion transfer for uninterrupted sleep.

You can select your level of firmness between :

• Firm
• Medium
• Plush

Our foam is also better than traditional memory foam because it recovers its shape faster. With a typical foam mattress, you often wind up "stuck" when you change positions but the mattress is still holding your previous shape. That's because it takes around 60 seconds for the foam to bounce back.
Ours bounces back in just four seconds, so as you move at night your mattress keeps up with you, providing superior comfort.

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 Hybrid): 12.5" More airflow and a cooler sleep combined with firm support.
• Max Cooling Upgrade (CF3000 Hybrid): 13" Cooler and more breathable.
• Max Cooling & Pressure Relief Upgrade (CF4000 Hybrid): 14" Feels and sleeps cooler, with air support layer to take pressure off joints.

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.

A highly breathable and supportive mattress with a classic, responsive feel.

Our Bio-Pur® foam is five times more breathable than traditional memory foam, because of its advanced open-cell structure. It wicks away heat while you sleep and can help keep you cool and comfortable.

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.

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.
