Nest Bedding Sparrow Signature Hybrid vs Brooklyn Bedding Plank Firm

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.

Our dual comfort design offers two variations: the top side of the mattress is firm; the bottom side is ultra-firm, allowing for an easily flippable, highly customizable sleep.

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.)

Inspired by the minimalist approach to sleep in the Far East, the Plank is the firmest, flattest, healthiest way to sleep. It has 4 layers of construction:

1. Optional: GlacioTex™ Cooling Cover (Extra Firm Side)
2. .75” Quilted Top
3. 6” High-Density Base Foam
4. 2” Supreme Response Comfort Foam
5. .75” Quilted Bottom
6. Optional: GlacioTex™ Cooling Cover (Firm Side)

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).

Engineered to reduce pressure on your circulatory system the Plank provides for better blood flow - and better lower back support, compelling you to inhale more oxygen while you snooze.

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 Plank offers a firmer, flatter, flippable surface for a neutral spine position that's better for your back and posture overall.

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 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 2" layer of our firmest transitional TitanFlex™ foam adds deep compression support.
A 7" high density base foam ensures durability and stability for the life of your bed.

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.

The flippable design of the Plank allows you to choose your ideal firmness level: a .75" quilted top layer, patterned with continuous stitching, ensures zero loft for an ultra-firm sleep experience - or, flip the mattress, and a 1.5" quilted layer, patterned with tack-and-jump stitching, creates minimal loft for a firm sleep experience.
