Amerisleep AS1 vs BedInABox Tranquillium

The AS1 is our firmest mattress, it offers gentle-but-firm support that stays cool all night. It's a great choice for back and stomach sleepers who like extra support.

A firmer and supportive feel.

Two layer construction:

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

A 3-layer construction:

• 3" 3lb Density CoolRest® Memory Foam Infused with Liquid Gel
• 2" Pluralux Foam
• 7" 2lb Density Sure Align Support Foam
• Smooth Knit Cover.

Our foam is also better than traditional memory foam because it recovers its shape faster. With a typical foam mattress, you often wind up "stuck" when you change positions but the mattress is still holding your previous shape. That's because it takes around 60 seconds for the foam to bounce back.
Ours bounces back in just four seconds, so as you move at night your mattress keeps up with you, providing superior comfort.

3 lb density memory foam rebounds (takes it shape) quicker making it easier to change positions.
The TENCEL® cover is a performance fabric like no other, absorbing moisture completely and naturally, creating a cooler and more comfortable sleep. With more breathability than cotton, and a softer hand than silk, TENCEL® can be found anywhere from athletic wear to luxurious bedding. Nothing is dreamier than going to sleep on a bed made with TENCEL® fibers.

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.

Our CoolRest™ gel advanced memory foam quickly conforms to your body for pressure relief and support without letting you sink too far into the mattress.

Our Bio-Pur® foam is five times more breathable than traditional memory foam, because of its advanced open-cell structure. It wicks away heat while you sleep and can help keep you cool and comfortable.

Open cell memory foam increases air flow, contributing to a cooler sleep.
Sure Align foam works in tandem with CoolRest® Gel memory foam and provides perfect support for long lasting comfort.

Bio-Pur® breathes and conforms to your body. When you lie down, you'll feel Bio-Pur® relieve your pressure points.

CoolRest® Gel memory foam perfectly contours to your body providing improved pressure relief to reduce tossing & turning.
Sure Align foam designed to support & correctly align your spine so you can sleep better.

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.

The TENCEL® cover offers unique moisture management properties - absorbs 50% more moisture than cotton, making it a highly effective performance fabric. Rapid absorption of moisture proves most effective in inhibiting bacterial growth naturally, without adding any chemicals.
