Amerisleep AS2 vs Saatva Zenhaven Latex

The AS2 is our medium-firm mattress, and it's our most popular with back and stomach sleepers. It's thicker than the AS1 and contains a transition foam layer, giving it slightly more cushion.

Two comfort levels within the one mattress, 80% of latex customers choose a Luxury Plush comfort range (a 4-5 on the firmness scale). It conforms and supports your body effortlessly while still maintaining an ultra-luxurious, plush feel. The Gentle Firm side is 18% firmer than Luxury Plush, for those who want a slightly firmer feel. Gentle Firm still provides uplifting, pressure-free support (a 7-8 on the firmness scale). How do you choose a Zenhaven comfort level? You simply flip the mattress over.

Three layer construction:

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

Pure tree-tapped latex and advanced 2-in-1 comfort innovation create the ultimate sleep experience.

• 1" Organic Wool Layer (both sides of Zenhaven have a flame-retardent barrier made of 100% organic New Zealand wool, not chemicals, which also adds breathability and moisture-wicking properties)
• 2x 1.5" 100% Talalay Latex "5-Zone" Comfort Layers (N2 - gentle firm side, N1 - luxury plush side)
• 2x 3" 100% Talalay Latex Support Cores (N4 - gentle firm side, N3 - luxury plush side).

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.

Zenhaven's American-made Talalay latex offers a range of health benefits. It's naturally hypoallergenic and resistant to mold, microbes and dust mites. It contains no volatile organic compounds or other harmful substances found in chemical-based bed foams. And it has a uniquely resilient feel that elevates and conforms to your body for perfect support, total comfort, and a truly restorative night's sleep.

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.

By varying the size and distribution of the "pinholes" formed during the Talalay process, we created a seamless mattress layer with 5 distinct zones of density, providing Zenhaven with firmer support beneath the torso and shoulders and more subtle support elsewhere. The result is pressure-free support and better spinal alignment.

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.

Latex has an open cell structure that allows air to circulate freely, countering body heat and providing cool, comfortable sleep. This natural air flow gives you a mattress that's seven times more breathable than other types of latex.

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.

Natural latex is the best-kept secret in sleep, and once you have experienced it, nothing else will do. It instantly responds to every curve of your body for pressure-free support and incomparable comfort on both traditional and adjustable bases. A Zenhaven exclusive, our Talalay latex comfort layers feature a proprietary 5-zone design that gives you firmer support where you need it for the ultimate in comfort and spinal alignment.

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.

Organic Cotton Cover
A cover of quilted organic cotton completes one of the world's healthiest and most comfortable natural latex mattresses.
