Amerisleep AS1 vs Helix Plus

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.

Medium feel top of the bed you need - not too firm, not too soft. Rated a 7 to 8 on the firmness scale. Maximum support - to help provide maximum support for people with high BMIs.

Two layer construction:

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

The Helix Plus is designed for Plus Size and Big & Tall and offers maximum support with a medium feel, it has five layers of construction:

• Tencel Cover
• 1.5" Helix Dynamic Foam
• 1" Gel Memory Foam (Density: 4.0 lb)
• 1.5" Memory Foam Plus
• 8" Body Shaped Innersprings with reinforced perimeter
• 0.5" DuraDense Base Foam.

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.

Ultra breathable cover and hybrid design increase airflow to keep the mattress cooler. No more sweaty nights.

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 new Helix Plus has higher density foams to match heavier sleepers and provide increased durability. The coil unit has best in-class edge support, so plus size sleepers never feel like they're falling off the mattress. An extra layer of high density, 4 pound foam is included in one of the three foam layers to help provide maximum support for people with high BMIs.

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 special latex-foam hybrid alternative, designed to be denser to contour to your body.
Uniquely pressure relieving, we use 4 pound Memory Plus Foam - a special, ultra dense and extra durable Helix blend.

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

Firm Memory Foam provides ergonomic support and cushioning, the transition layer has a higher IFD to match your body type. Extra support.
Hundreds of individual taller coils designed to cradle and support heavier weight. Reinforced perimeter to provide edge support.
The bottom foam layer of the mattress provides base support and durability to the entire mattress.

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.

Each Plus mattress comes with our Ultra Breathable Tencel technology designed to increase airflow and to keep you cool.
