Amerisleep AS3 vs Lull Original

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.

Three layer construction:

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

3 layers of construction:

• 1.5" Viscoelastic Memory Foam Top Layer
• 1.5" Transition Layer made from a Proprietary Blend of Premium Foam
• 7" High-Density Polyurethane Foam Core Support Layer.

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.

The ideal temperature for sleeping is 69 degrees. Lull's 1.5" viscoelastic memory foam top layer is injected with a gel polymer, specifically designed to transfer heat away from your body when it is warm by dispersing your body heat throughout the mattress. Breathable top-tick fibers and open cell foam structure promote enhanced airflow to help heat flow freely away from you.

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.

The Lull Mattress supports and cradles your body to provide healthy spine alignment while you sleep. 1.5" transition layer made from a proprietary blend of premium foam combined with our 7" high-density polyurethane core support layer ensures the proper body alignment while you are sleeping. A healthy spine position allows your muscles to rest throughout the night and wake up refreshed in the morning.

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.

A common complaint about memory foam mattresses is that you sink and get stuck. Not with Lull. Our proprietary blend of premium foam was designed with just the right amount of bounce-back in mind. The 1.5" transition layer responds and supports your body so you don't get that sinking feeling or a trampoline-like experience.

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.

Lull's 1.5" top layer memory foam evenly distributes weight and contours to your body's curves, which provides relief for pressure points - joints, lower back & neck. Memory foam and specialty foams ensure the proper lumbar and neck support.

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.

Lull's cover is made of ultra-premium fabrics. Our cover surface is made from polyester and rayon to provide comfort, stretch and flexibility. It is incredibly soft, breathable and durable. It is hand-crafted and easily removable for spot cleaning.
