Amerisleep AS4 vs Saatva HD

The AS4 is our medium-soft mattress. It offers plush comfort with targeted support that helps you sleep your best. Plus it stays cool all night, making it our most popular model with side sleepers.

Medium firm comfort level suited for every type of sleeper. Specifically targetted to larger individuals. Saatva HD is specifically designed to support between 300 and 500 pounds. Twin and twin XL mattresses can accommodate up to 500 pounds. Full, queen, king, Cal king, and split king mattresses can accommodate up to 500 pounds on each side.

Three layer construction:

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

Introducing the Saatva HD, the first luxury hybrid innerspring mattress specifically engineered to support those who weigh between 300 and 500 pounds.

• Organic Cotton Pillow Top
• 2.5" Firm Talalay Latex
• Contouring Comfort Layers (including 5lb Memory Foam)
• High-Durability Coil Base
• Edge Support.

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.

All elements in the Saatva HD have been carefully considered to increase airflow throughout the mattress resulting in better temperature regulation.

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.

High-density foam rails (1.8lb density) encase the top, bottom, and sides of the mattress. This firmer, more supportive edge makes it easier to get in and out of bed. All elements in the Saatva HD have been carefully considered to increase airflow throughout the mattress resulting in better temperature regulation.

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.

100% natural Talalay latex that is hypoallergenic, and cool. This works with open coils and the breathable organic cotton cover to promote easy airflow for a cooler night's sleep.

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.

Tempered 12.5-gauge steel coils (25% stronger than the industry standard), threaded with 17-gauge helical wire to eliminate motion transfer. Patented Spinal Zone active wire adds lumbar support in the center third of the mattress.
5-zone Talalay latex feels buoyant and responsive. Resists body impressions and provides targeted support for your back and under your shoulders and hips.
A unique combination of memory foam and support foams contour and cushion for added pressure relief on your joints.

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.

The pillow top adds a layer of cushioning. Wrapped in a breathable organic cotton cover enhanced with Guardin® antimicrobial fabric treatment. Entire mattress is hand-tufted which prevents the shifting of the layers and eliminates body impressions by compression tufting.
