Firmness Info

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.

Mattress Construction

Materials Overview

A five layer construction:

  • 1" Gel Infused Memory Foam & Super Soft Quilted Thermic Phase Change Fabric
  • 3" Energex™ Temperature Responsive Foam (2.8 lb.)
  • 1" SmartFlow Support Foam (3 lb.)
  • 6" Reinforced Edge Coil Support Pocketed Coils
  • 1" Base Support Foam (3 lb.).
This mattress is eligible for Nest Bedding's Lifetime Renewal Exchange program. This LRE program is specifically designed to increase the lifespan of the mattress, but also to reduce waste in landfills, creating a much more eco-friendly option within the mattress industry. Your mattress will last 2-3 times longer as you will be given the opportunity to either redeem a new, free comfort layer within the 365-night trial or years after. The new comfort layer will breathe entirely new life into the mattress, extending its lifespan in the process.

Comfort Info

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).

Support Info

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.

Comfort Specs

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.

Support Specs

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.

Fabric Specs

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.
