Amerisleep AS1 vs Casper Nova Hybrid

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.

The best way to feel the Casper Nova Hybrid is to take advantage of our 100-night, risk-free trial. If you're looking for a mattress that can sustain more weight, or you want to be lifted more than cradled, then our hybrids are a great choice.

Two layer construction:

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

Those who want a plush top layer without sacrificing support and cooling. Made with three layers of premium foam, plus foam-encased springs:

• Breathable AirScape™ Polyurethane Foam
• Zoned Polyurethane Foam
• Contoured Memory Foam
• Durable Base of Polyurethane Foam with Encased Springs.

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.

Cooling helps keep you at the right temperature for your best. Two layers of perforated breathable foam help reduce heat. Plus every mattress saves up to 70 recycled bottles from the environment.

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.

Superior plushness without sacrificing support. More support where you need it most with the plushness you crave. Zoned Support™ Pro offers 7 zones of targeted support for healthy spinal alignment, softer foam around the shoulders provides more relief to the upper body and multiple ergonomic points under shoulders, hips, waist and lower back.
A firmer border provides edge support to help you get in and out bed easily.

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.

A top layer of proprietary perforated breathable foam helps reduce heat, the tiny holes move hot air and body heat away. With a thin coating of cooling gel that adds a refreshing feel. This innovative cooling system is designed to help keep you cool all night.
Second layer of AirScape™ helps prevent overheating. These air channels allow heat to escape.
Resilient springs increase airflow.

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

Premium AirScape™ foam conforms to your body to relieve pressure. This has a plush, velvety soft feel.
A second layer of supportive foam has 3 ergonomic zones to help align your spine and provide more relief.
A third layer with Zoned Support™ Pro relieves pressure under the shoulders, and provides more support under the waist, lower back, and hips to align your spine. These zones reinforce support from the layers above.
Fabric-wrapped springs provide active support and a little lift.

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.

A super plush and stretchy top. This velvelvety-soft layer makes bedtime feel extra cozy. Knit fabrics stretch in 4 ways so you feel the full benefits of the layers below. The added pillow-like fabrics cradle your body and make you feel as if you were sinking into a cloud.
