Firmness Info

The AS1 is our firmest mattress, it offers gentle-but-firm support that stays cool all night. It's a great choice for back and stomach sleepers who like extra support.

If you already know that you love a soft or firm mattress then follow your heart. However, if you are unsure you can follow this quick guide to make a selection:
1. Back Sleepers and Stomach Sleepers should choose the Firm Mattress
2. Side Sleepers and 'Free Style' Sleepers should choose the Soft Mattress
3. If either you or your partner is heavier than 220 lbs, the Firm Mattress may be the option for you.
4. If you are lighter than 130 lbs, the Soft Mattress may be the option for you.

Mattress Construction

Materials Overview

Two layer construction:

  • Bio-Pur® foam
  • Bio-Core® foam support layer
  • Refresh Cooling Cover.

Whether you prefer a firm or a softer experience, our hybrid mattresses play with varying layers of foam, natural latex and our pocket coil system.
Firm:

  • 1" Cooling Infinity Foam
  • 2" Responsive Natural Latex
  • 8" Edge-to-Edge Coil System
  • 1" High Density Support Foam
Soft:
  • 2" Cooling Infinity Foam
  • 1" Hybrid Transition Foam
  • 8" Edge-to-Edge Coil System
  • 1" High Density Support Foam.

Comfort Info

Our foam is also better than traditional memory foam because it recovers its shape faster. With a typical foam mattress, you often wind up "stuck" when you change positions but the mattress is still holding your previous shape. That's because it takes around 60 seconds for the foam to bounce back.
Ours bounces back in just four seconds, so as you move at night your mattress keeps up with you, providing superior comfort.

With reduced motion transfer, you and your partner can experience an uninterrupted night's sleep for your perfect sleepy sanctuary.

Support Info

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 various blend of ingredients deliver the perfect amount of body contouring and pressure relief with extra soothing support. The Infinity Foam top layer is our unique material that prevents heat retention for a cooler night's sleep, and gives the perfect balance of support, contouring, and pressure relief in all the right places. This is our finishing touch to give you an unparalleled indulgent experience.

Comfort Specs

Our Bio-Pur® foam is five times more breathable than traditional memory foam, because of its advanced open-cell structure. It wicks away heat while you sleep and can help keep you cool and comfortable.

Our unique foam construction provides contoured support & breathability for the coolest night's sleep.

Support Specs

Bio-Pur® breathes and conforms to your body. When you lie down, you'll feel Bio-Pur® relieve your pressure points.

Our edge-to-edge pocket coil system was created to provide superior edge support. Each coil is individually wrapped so it can compress and expand independently, providing you with pressure relief where you need it most. The coils are positioned between layers of foam to allow you to feel like you're floating on air.

Fabric Specs

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.
