Amerisleep AS1 vs Nest Bedding Raven Flippable Foam 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.

This luxury hybrid foam and coil mattress comes with a medium feel on the top and a feel firm on the bottom, allowing sleepers to try both sides for optimal comfort. With our two-in-one comfort design, this mattress is ideal for side, back, and stomach sleepers. The medium side is about a 5 on the firmness scale and the firm side is about an 8.

Two layer construction:

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

The Raven is an affordable premium memory foam flippable hybrid mattress with two firmness levels in one bed and a breathable quilted top. It is constructed with the following layers:

• 1" Quilting Foam Cover
• 1" Cooling Visco Gel Support Foam
• 6" Reinforced Edge Coil Support Pocketed Coils
• 1" High Density Foam
• 1" Quilting Foam Cover.

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.

Two breathable and ergonomically supportive sleep surfaces in a medium and firm feel designed for side, stomach and back sleepers. Sleeps comfortable and cool, with built in airflow and cool sleeping fabric.

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.

Nest Bedding combined cooling Visco Gel support foam with a durable coil system, granting two sided firmness in a flippable hybrid luxury mattress.

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.

The medium side has memory foam infused with cooling gel in the comfort layer. The cooling gel infusion is designed to reduce overheating. The built-in airflow will allow you to sleep cool and comfortable all night long.

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

A synthetic polymer visco memory foam that forms to the shape of your body and reshapes to its former structure as pressure is removed. This support foam structure provides excellent pressure point relief.
Individually wrapped coil system offers reinforced edge support.
High-density foam offers additional structure and support to the firm side.

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 quilted foam cover on both the top and bottom of the mattress means you'll sleep cool and comfortable no matter which side you choose! A soft but resilient polyfoam is used to give a plush and soft pillow top feel that won't flatten or compress over time.
