Amerisleep AS4 vs Allswell Luxe Hybrid

The AS4 is our medium-soft mattress. It offers plush comfort with targeted support that helps you sleep your best. Plus it stays cool all night, making it our most popular model with side sleepers.

After many iterations, we finally nailed what we think is the perfect recipe for the ideal medium-firm feel. A 4.5 to 6.5 on the firmness scale.

Three layer construction:

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

Built-in plush topper is actually a combination of 3 foams, which make up 1 layer, comprising:

• 1" of memory foam (2lb density 9 ILD)
• 0.25" of super soft foam (1.5lb density 20 ILD)
• 0.25" of super soft foam (1.125lb density 20 ILD)
• Layer 2: 1" of air flow foam (2.75lb density)
• Layer 3: 2.5" super soft foam (1.7lb density)
• 7.5" 13 gauge individually wrapped coils.

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.

Allswell performed robust internal technical testing on over 100 dimensions and quality cues (e.g., durability, breathability, comfort, etc.) and these impressive features and benefits amount to a mattress so luxurious it's hard to believe it ships in a box.

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 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.

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.

The firmer layers the same memory foams as the classic atop several hundred individually wrapped 13-gauge coils for added 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.

Luxe Cooling Exterior
Our mattresses are quilted in a special fabric designed to feel cool to the touch and are constructed with natural ingredients like plant-derived oils, charcoal and green tea extract.
