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.

The AS2 is our medium-firm mattress, and it's our most popular with back and stomach sleepers. It's thicker than the AS1 and contains a transition foam layer, giving it slightly more cushion.

Mattress Construction

Materials Overview

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.)

Three layer construction:

  • Bio-Pur® foam
  • HIVE® transition layer
  • Bio-Core® foam support layer
  • Refresh Cooling Cover.
Now available in a Hybrid (no HIVE layer but with a foam-encased pocket springs layer, see the AS2 Hybrid)

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).

Traditional memory foam is made from dense material, so it traps your body heat and can make you sweaty and uncomfortable while you're in bed - and who can sleep like that?
We developed our foam with an enhanced "open cell structure", which means there is more air space between the foam particles. That space wicks away heat while you sleep, and can keep you cooler and more comfortable.

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.

Our Bio-Core® foam support layer won't sag even after decades of use. And, like our Bio-Pur® foam, it's partially made from plants instead of petroleum so it's eco-friendly.
The HIVE® layer features hundreds of foam hexagons grouped into five comfort zones. Each zone is designed to provide extra cushion where you want it and support where you need it. That way your body gets the support it needs to stay properly aligned, so you can sleep your best.

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.

The HIVE® transition layer has precision-cut channels that carry away even more heat and moisture. It's enough to make you feel like you're weightlessly resting on a cloud.
Amerisleep's Bio-Pur® material features an advanced-open cell design. This makes Bio-Pur® more breathable and responsive than memory foam, which will keep you cool and comfortable all night. Plus we make Bio-Pur® from partially plant-based sources using a zero-emission process. That means it's the most eco-friendly material of its kind.

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.

Bio-Pur® contours to your body to relieve pressure points and bounces back fast, so you won't feel "stuck" during the night.
Our HIVE® transition layer provides targeted support and pressure relief so you can sleep in perfect alignment. It gives your head, back, and legs more support, and your shoulders and hips more cushion.

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.

Refresh Cooling Cover
The Refresh Cover draws heat from your skin for a delightfully cool-to-the-touch feel. On average, your sleeping surface will stay 7 degrees cooler over an eight-hour night of rest compared to a traditional 100% polyester cover. This scientifically engineered fabric uses minerals to help convert your natural body heat into far infrared energy. This type of energy increases blood circulation to help speed up muscle recovery and improve quality of sleep.
