Amerisleep AS4 vs Sleep EZ Select Sleep 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.

The Select Sleep Hybrid is a dual-comfort two-sided mattress. Choose between plush on one side, or flip it over for a firmer feel.

Three layer construction:

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

The Select Sleep Hybrid Mattress is a flippable (two-sided) mattress that has:

• an Organic Cotton Cover quilted on both sides to Joma Wool (from New Zealand)
• 5" 100% Natural Latex Rubber
• 8" Quantum Edge Elite Pocket 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.

The Select Sleep Hybrid latex mattress delivers incredible comfort at an incredible value. Now you can experience the healthy benefits and superior comfort qualities of natural latex over individual coils at a price that will let you sleep well at night.

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.

Quantum Edge steel perimeter gives your bed a consistent level of support all the way to the edge.

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.

Select Sleep Hybrid features 5 inches of 100% natural latex rubber, made from sustainably harvested resources. It is an eco-friendly material offering resilience, durability, and temperature control that far exceeds synthetic, petroleum-based polyurethane 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.

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 on both sides with New Zealand Joma wool to our organic cotton four-way stretch fabric; this mattress is natural, it's healthy, and oh so comfortable.
