Amerisleep AS3 vs Novosbed

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.

Novosbed mattresses are available in 3 firmness levels, and all are covered by our Perfect Firmness Guarantee, 120 night sleep trial, and 15 year warranty. Soft: Designed for contouring and plushness without that "quicksand" feeling. Medium: Designed to offer the perfect balance of support and plush-comfort and Firm: Designed to provide firm, comfortable support, with minimal sink-in.
* Not quite right? Call Novosbed and they'll send you a Comfort+ kit for free. Unzip the mattress top cover and lay the Comfort+ layer on top. Zip the Comfort+ extender to the base and then to the top cover. Your Novosbed is softer or firmer, as needed. The whole process usually takes less than 2 minutes.

Three layer construction:

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

3 layers of construction:

• Premium Airflow Gel Foam
• Premium Memory Foam
• Premium Support Foam

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.

InterLock Blue™ Core Cover
Knitted with advanced 2-way stretch, InterLock Blue™ adds a second layer of protection for the foam core, and a second layer of moisture guard for added coolness and comfort.

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.

2 to 3" Premium Memory Foam
Perfect comfort and pressure relief, this layer adds 3 luxurious inches of plush support memory foam to the heart of your Novosbed.

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.

2" Premium Airflow Gel Foam
A highly breathable gel memory foam for ultra-luxurious comfort with heat dissipation far superior to that of traditional memory foams.

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.

Like billions of tiny independent cushion pocket-coil springs, this premium support foam layer supports sleepers while eliminating motion transfer during the night.

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.

Ultra-soft, Moisture-wicking, Washable Cover
Made from eco-friendly Tencel® fabric, the luxurious Novosbed top cover draws moisture away from your body for a cool, dry night. It is also removable and machine-washable.
