Nest Bedding Sparrow Signature Hybrid vs Molecule 2

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.

On a scale of 10, our mattress has a 6.5 firmness level. We like to refer to it as a "medium firm" - soft at the top, firmer in the middle.

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.)

Each component of the MOLECULE mattress has been engineered to work synergistically to maximize support, comfort and heat dissipation for the best recovery-focused sleep. Featuring a 4 layer construction:

• 1" BioCharge™ layer
• 2" AirTEC™ layer
• 3" RecoveryFLO™ layer (Density: 1.65lbs, ILD: 40)
• 6" ContourFLO™ layer (Density: 1.5lbs, ILD: 35).

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).

Better sleep leads to peak performance. It's not just the quantity of your sleep, it's the quality. Your body restores itself most during Slow Wave Sleep - replenishing blood and oxygen and releasing essential hormones. Sleep scientists and athletes engineered Molecule's unique sleep system so you benefit from the most revitalizing stage of rest, optimizing your body's recovery and performance.

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.

The firm base support fosters healthy spine alignment.

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.

The most restorative rest happens when your body temperature is cooler. Only Molecule offers this revolutionary airy, extreme open-cell structure for consistent cooling even when compressed by your body weight. Cozy support with more than seven-times the airflow of traditional memory foam. Active people need more support and airflow than traditional egg-crate foam mattresses can deliver.

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.

Ergonomically-engineered Molecule features a meticulously-engineered matrix of hexagon-shaped channels that respond to your unique anatomy and promote airflow even at the deepest depression points. You awake refreshed with relief from sore muscles and joints. Larger hexagon zones in the center designed for additional support and pressure relief in the lumbar region. Varying hexagon zone density around the legs and feet to support the lower body.

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.

Cover is 98% Polyester, 2% Lycra. It wicks away heat and moisture to keep skin comfortably cool. As your body temperature changes throughout the night, Molecule's advanced cover material responds dynamically, adjusting evaporation and cooling. Microban® antimicrobial treatment keeps your mattress fresh and clean.
