Amerisleep AS3 vs Diamond Transformation Hybrid

The AS3 is our most versatile mattress. It evenly blends support and softness, so it's great for people who change positions as they sleep and couples with different sleep styles. It's also our most popular mattress overall.

Everyone has their ideal comfort level. That's why we've designed this comfort selector tool so that you know exactly what you're jumping into. Select from 3 firmness levels:

• Soft, a 3/10 on the firmness scale, a light, gentle and flexible feel that conforms to your body.
• Medium, a 5/10 on the firmness scale, the best of both worlds for an exceptionally comfy feel.
• Firm, an 8/10 on the firmness scale, solid and stable support throughout your sleeping surface.

Three layer construction:

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

The Transformation Mattress by Diamond Mattress is constructed of:

• 2" CoolTouch Advanced Regulating Fabric
• 2" Diamond Hyper Conductive Sparkle Foam
• Mirco Coil Comfort Layer
• 2" HD Comfort Layers
• Patented Zoned Support System - Foam Encased.

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.

Foam Encased Comfort Edge: Increases usable sleep surface by allowing you to sleep all the way to the edge without feeling like falling off. Creates a better edge for entering, exiting and sitting on the side of the mattress.

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.

Combination Foam and Coils: Superior Pressure Relief. Contours to your natural shape to help achieve a comfortable sleeping posture. Hyper conductive foam regulates core temperatures for a natural sleep. Coils provide breathability and additional comfort and support.

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.

Diamond Sparkle Foam actively regulates your core temperature for the most natural sleeping environment. Graphene and conductive flakes dissipate heat from the surface of the skin.
Wrapped coil design enhances airflow and breathability to keep you sleep environment more comfortable.

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.

Patented Zoned Support System: Adding 25% more support where you need it most

1. Additional Wrapped coils in the center 3rd provided extra back support where you need it.
2. Improves alignment by relieving pressure along the shoulders, back and hips
3. Prevents motion transferred between partners for less disturbance

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.
