Nest Bedding Sparrow Signature Hybrid vs Sealy Cocoon Chill

Available in Plush (2.5-3), Medium (4-4.5) or Luxury Firm (7.5-8). Does your partner like different types of mattress firmness than you? Order the Sparrow Signature Hybrid in King and Cal King sizes and get a different firmness on each side. Keep one side firm and the other plush, or mix a plush side with a medium. With the Sparrow Signature Hybrid mattress, during or after your sleep trial, you can swap out the inner layer of foam to adjust its firmness without needing to get a whole new mattress.

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.

A five layer construction:

• 2" Quilted THERMIC® phase change cover & 4 lb. Memory Foam
• 3" Energex™ Temperature Responsive Foam (3 lb.)
• 1" SmartFlow Support Foam (1.5 lb.)
• 6" Reinforced Edge Coil Support Pocketed Coils
• 1" Base Support Foam (3 lb.)

3 layer construction:

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

Unzip the sides of this mattress to exchange the inner foam layer for a new one that's more firm, softer, or if you just want to replace it (which extends the life of your mattress).

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.

Energex™ foam is a cutting-edge foam layer that fully supports your body with the pressure relief of memory foam, and the responsiveness and durability of latex. This combines with the support of high quality individual coils with extra edge support.

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.

The top layer is temperature responsive, highly adaptive, durable, and breathable specifically designed to energize in response to body heat.
We use our SmartFlow air flow system with punched foams and breathable layers to achieve maximum air flow.

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

The mattress (formerly called the Alexander Signature Hybrid Mattress) utilizes a very durable individually pocketed coil unit with edge support coils all around the perimeter. This provides a movement-free sleep surface and supports the back perfectly.

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

A soft quilted, luxurious top layer of fabric greets you and provides a cool, comfy surface. This Thermic Phase Change Cooling fabric will help your body regulate its ideal sleeping temperature through the seasons.

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.
