Serta iComfortECO Foam vs Sealy Cocoon Chill

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 Cocoon Chill is a medium firmness, about a 6 on the firmness scale. We've found that most sleepers prefer a mattress that's fully supportive but not too firm, so we created a mattress with our Perfect Fit memory foam that adapts to your unique body size, shape and sleep position.

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.

3 layer construction:

• Perfect Fit Memory Foam
• Personalized Comfort Layer
• Support Foam.

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.

A top layer of memory foam helps reduce the amount of movement from your sleep partner. The Soft model reduces a bit more motion transfer than the Firm model.

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

Our high-quality memory foam adapts to your body size, shape and sleep position to ensure a great sleep no matter which feel is right for you.
