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.

Medium feel top of the bed you need - not too firm, not too soft. Rated a 7 to 8 on the firmness scale. Maximum support - to help provide maximum support for people with high BMIs.

Mattress Construction

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

The Helix Plus is designed for Plus Size and Big & Tall and offers maximum support with a medium feel, it has five layers of construction:

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).

Ultra breathable cover and hybrid design increase airflow to keep the mattress cooler. No more sweaty nights.

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.

The new Helix Plus has higher density foams to match heavier sleepers and provide increased durability. The coil unit has best in-class edge support, so plus size sleepers never feel like they're falling off the mattress. An extra layer of high density, 4 pound foam is included in one of the three foam layers to help provide maximum support for people with high BMIs.

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.

Our special latex-foam hybrid alternative, designed to be denser to contour to your body.
Uniquely pressure relieving, we use 4 pound Memory Plus Foam - a special, ultra dense and extra durable Helix blend.

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.

Firm Memory Foam provides ergonomic support and cushioning, the transition layer has a higher IFD to match your body type. Extra support.
Hundreds of individual taller coils designed to cradle and support heavier weight. Reinforced perimeter to provide edge support.
The bottom foam layer of the mattress provides base support and durability to the entire mattress.

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.

Each Plus mattress comes with our Ultra Breathable Tencel technology designed to increase airflow and to keep you cool.
