Amerisleep AS4 vs GhostBed Flex

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 GhostBed Flex is a 5.5 to 6.5 out of 10 on the firmness scale (10 = too hard, 0 = too soft). The feel is slightly softer than the GhostBed.

Three layer construction:

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

If you've always loved traditional innerspring mattresses, but you're tired of wearing a groove in every mattress after just a couple of years, the GhostBed Flex is made for you. The GhostBed Flex has 7 layers:

• Ghost Ice Fabric - Smooth, silky viscose-polyester blend
• 1" Cool Fiber Layer - Creates air flow so you sleep cooler
• 1" Gel Memory Foam - Gives that Ghost Hug feel
• 1" Gel Memory Foam - Relieves pressure and wicks away heat
• 1" Ghost Flex Soft Transition Foam - Reduces the urge to toss and turn
• 8 .5" Individually Wrapped Support Coils - Enjoy the sturdy, responsive support of the traditional innerspring mattresses you're used to
• 1" High Density Support Foam - Extra support and durability from the base up.

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.

Our 7-layer hybrid mattress fuses the springy support of individually-wrapped coils with the plush comfort of gel memory foam. Experience out-of-this-world comfort, with the best of both worlds.

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 core of the GhostBed Flex features the patented Ghost Flex innerspring coil unit with our Spirited Edge™ Support design. Individual 8.5" coils create the weightless feeling you love, while wrapping them individually creates minimal motion transfer. Plus, two rows of specially reinforced coils along the edge of the bed make it easy to sit comfortably without slipping off.

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.

Two one inch layers of special gel-infused Memory Foam absorbs and dissipates body heat as fresh air passes through the foam.

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.

One inch of Ghost Flex Soft Transition Foam offers pure pressure relief. This layer of soft transition foam contours to your body and reduces the need to toss and turn.
Individual coils offer the responsive support of traditional innerspring mattresses, without the worry of wearing out after just a few months. Additionally, the coils near the edge of GhostBed Flex are specially reinforced for better support - so you can sit on the edge of your bed without sliding off.

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.

Cooling fiber is woven directly into the cover to help create airflow. Topped with Ghost Cooling Fabric for a refreshing feel.
