Nest Bedding Sparrow Signature Hybrid vs Brooklyn Bedding Spartan

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.

Three levels of firmness let you decide the level of support you need.

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.)

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).

Patented Energex™ is paired with TitanCool™, a water-based surface infusion with high conductivity properties that draw excess heat away from the body, maintaining optimal comfort for each individual sleeper. An infusion of copper helps promote an antibacterial sleeping environment.
Combining an elite performance fabric, registered with the FDA, with the patented advanced cooling of TitanCool™, the Spartan helps you reset and rejuvenate quicker by harnessing and recycling the body's natural energy throughout the sleep cycle.

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.

A transitional layer of swirl memory foam provides enhanced contouring and deeper compression support with added cooling.

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.

A second 2" layer of hyper-elastic TitanFlex™ foam provides cloud-like comfort with immediate response technology that adjusts to your body each time you move.
A patented phase change molecule surface infusion of TitanCool™ maintains body temperature at an ideal 88 degrees.

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.

A 1.5" top layer of patented CopperGel Energex™ foam provides responsive contouring with targeted pressure point relief and the highly conductive, antimicrobial properties of copper.
A third 1" Swirl Visco-Elastic Memory Foam layer provides enhanced contouring and deeper compression support with added cooling.
An 8" base of up to 1,189 individually encased Quantum™ Edge coils delivers ultimate pressure point relief while decreasing motion transfer.

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.

An exclusive performance top, made of patented Nanobionic RE-3™ technology, transforms your body's heat into waves of energy, reflected back to you through the medium of fibers - using technology that has been clinically proven to increase oxygenation and improve circulation as well as sleep quality, health and wellness.
