Sealy Cocoon Chill vs Helix Moonlight

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.

Softer top of the bed to give you that plush comfort you love. Like sinking into a cloud. Extra support - best for back and stomach sleepers, or side sleepers with larger body types. A 2-3 on the firmness scale.

3 layer construction:

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

The Moonlight offers extra support and a plush feel, it has four layers of construction:

• Cover: Helix Two Touch Design
• Comfort Layer: Helix Dynamic Foam (Density: 2.45 PCF)
• Transition Layer: Helix Transition Foam
• Body Shape Layer: 6" Wrapped Coils
• Base Layer: DuraDense Foam.

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.

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.

Specially designed using proprietary Helix Dynamic Foam to react to your body shape and aid recovery.
Density of the top and middle layers optimized to give you extra support based on your body type.

Phase Change Material (PCM) absorbs your body heat leaving you with a cool to the touch mattress experience.

Our special latex-foam hybrid alternative, designed to react and contour to your body.

Support Foam base layer engineered to be highly durable and resilient. We've tested it, and we know it bounces back every time.

Helix Transition Foam
Providing ergonomic support and cushioning, the transition layer has a lower IFD to match your body type. Extra support.
Wrapped Coils
Hundreds of individual coils help to cradle your body while also limiting motion transfer.
Edge Support
Each mattress has an individually wrapped spring unit with a reinforced perimeter. This means your mattress will reduce that roll-off feeling and will keep its shape more while sitting on the edge of the bed. Our technology is proven to be substantially better than all foam options.

Our premium stretch-knit cover is infused with a proprietary "Phase Change Material" that absorbs and dissipates heat for a refreshing, cool to the touch surface.

Helix Two Touch Design
Each mattress comes with a top cover layer with stretch and a soft touch as well as a lower cover layer for airflow and breathability. Top cover - 100% soft polyester. Lower cover - Jersey knit fabric with woven fire barrier.
Upgrade to ultra cool knit cover for cooler nights (available at checkout). This Ultra-Cool Cover is designed using phase change material to keep your body cool when you sleep. Simply zip on the Ultra-Cool Cover in place of your standard cover for quick and easy use.
