Casper Original vs Nest Bedding Sparrow Signature Hybrid

Award-winning comfort, signature "just right" feel. It's a medium-firm feel and support.

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 Casper Original is good for sleepers of all kinds who want both support and cooling. Three layers of construction:

• Breathable Polyurethane Foam
• Zoned Memory Foam
• Durable Polyurethane Support Foam.

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.)

A layer of Airscape™ perforated breathable foam increases airflow and circulates air so you don't get too hot at night.

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).

Premium foam conforms to your body to relieve pressure.
Zoned Support™ provides a layer of memory foam with 3 ergonomic zones to help align your spine and provide more relief.
The durable base is engineered to prevent sinking and sagging while supporting your whole body.

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.

Stay cool all night with the innovative cooling system. AirScape™:

• A top layer of perforated breathable foam helps reduce heat.
• Tiny holes move hot air and body heat away.

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.

Get all-night comfort with the innovative support system. Zoned Support™:

• 3 zones of targeted support for proper spinal alignment.
• Softer foam around the shoulders provides more relief to the upper body.
• Firmer foam under the hips, waist, and lower back helps align your spine.

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.

Planet-friendly textiles. Up to 57 recycled bottles in each cover.

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.
