Nest Bedding Sparrow Signature Hybrid vs WinkBeds GravityLux

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 GravityLux by WinkBeds is available in 3 different firmness options:

• GravityLux SOFT, a 4/10, is designed for sleepers with a preference for a plush comfort level. Great for those who sleep on their side or if you simply prefer an overall softer feel.
• GravityLux MEDIUM, a 5/10, our most popular comfort level and the "just right" spot for our choosiest customers who like a medium feel. Not too firm and not too soft - it's a fit for all sleep positions and body sizes.
• GravityLux FIRM, a 7/10, is designed for sleepers with a preference for a firmer comfort level. Great for those who sleep on their stomach or back and also enjoy an overall firmer feel.

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).

Each tiny cell acts like an individual shock-absorbing cushion, releasing air independently as pressure increases, and ensuring individualized comfort and support.

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 GravityLux features 7 progressive layers of support, relieving pressure through the hips and shoulders and providing enhanced support through the lumbar and lower back. We achieve this through a proprietary foam texturization and fabrication process.
Each shock-absorbing air capsule moves independently to each other, quickly absorbing motion from a restless partner, and effectively stopping movement transfer to other parts of the bed.
AirCell™ has an open-cell structure of billions of micro air capsules that comfortably mold to your body weight, keeping your muscles relaxed and joints aligned.

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.

Unlike traditional memory foam, AirCell™ isn't temperature sensitive, and dissipates body heat faster. It draws heat from your body, dispersing it throughout the mattress to keep you cool.

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 two-layered Gel Foam top ensures your back, hips and shoulders get exactly the right level of cushioning and support, easing stress and muscle tension.
AirCell™ Memory Foam: with revolutionary pressure relief and contouring, pushback body support in varying zones, AirCell™ Foam is designed to relieve pressure and target support where you need it most.
Zoned Progression Foam provides targeted support in 5 zones with varying firmness levels: firmer support in the hips and lumbar region, softer in the shoulders and legs.

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.

Sleep cool and dry with our Eucalyptus-derived TENCEL® cover. Tufted with 2" of premium cooling gel foam inside, it enables airflow and wicks away body heat and moisture.

Your new mattress can take up to 2-4 business days to make as they are made to order by hand in the USA. Then, we ship from the West Coast, so depending on where you live, it can take 1-5 business days in transit.

It takes about 2 weeks to receive your mattress from the time you place your order. The first 3 to 5 days are dedicated to manufacturing your mattress fresh to order. Once the mattress ships out and reaches your local area, our delivery team will contact you to schedule a delivery day.
