Amerisleep AS4 vs Saatva Loom & Leaf

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.

L&L Relaxed Firm, rated a 6 on the firmness scale, is our flagship comfort level - not too hard, not too soft, "just right" support.
L&L Firm, rated an 8 on the firmness scale, for customers who want a very firm feel.

Three layer construction:

• 5.5" High-Density Foam Support base.

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.

We have developed a unique cooling gel panel that we've layered onto the spinal area promoting ultimate coolness. We also swirl our gel into our top layer of memory foam to further promote a restful 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.

Loom & Leaf mattresses are constructed with 4 progressive layers that work together to provide maximum support, comfort, and cooling.

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.

Cooling spinal gel
Our proprietary Spinal Zone Gel layer is created with cooling gel so you stay cool with optimal spinal support.

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.

Visco-elastic memory foam
This is the core or "heart" of the mattress, and the layer that gives your body that deep contouring 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.

Quilted, organic cotton covering
Our breathable, organic cotton covering and natural thistle flame retardant keep you comfortable, cool and safe.
