Key characteristics of Amerisleep Liberty mattress

  • The Amerisleep Liberty Bed is 12” tall, 2 inches more than the 10” mattress size that competitors offer in this category. This extra thickness adds more durability and support compression.
  • Liberty like other Amerisleep mattresses is officially licensed to use Celliant® in their covers which retains heat and helps for a restful sleep experience overall.
  • It features Bio-Pur plant-based memory foam layer for an eco-friendly and healthier lifestyle as well as a great cooling effect.

The one thing that sets apart Liberty as well as the rest of the Amerisleep beds, is the surface cover of the mattress. This contains unique fibers infused with a mineral-based material called Celliant.

Celliant is also used in the Bear mattress and is designed to take excess body heat, absorb it, and recycle into infrared energy. Its benefits relate to pain relief for athletes and boosting circulation, while some tests reveal that it helped people fall asleep faster.

The highly stretchy nature of the cover material thanks to the Celliant benefits allows the memory foam below to fully contour to your body and instantly goes right back to its original shape afterward. Some mattress covers use stiffer materials, which can reduce comfort.

In particular, for the Liberty mattress cover surface, it has also a modern textured look with a wave design, feeling cool and sleek to the touch.

Beneath the cover, Amerisleep designed a fiber fire barrier to meet flame standards, which is GreenQuard certified for healthier protection.

The added advantage of Amerisleep Liberty mattress is how it is ideal for side sleepers and for some combo sleepers. Overall, our testing suggested that each person’s hips and shoulders could sink far enough to keep their spine in a natural, comfortable alignment.

Amerisleep Liberty bed mattress is the right match if you

Want a medium feel – It offers a true medium feel, rated in a 5.5-6 out of 10 on the firmness scale, where 10 is the most firm. This provides with that right amount of balance between support and comfort and has excellent temperature control.

Want to sleep cool – The Liberty mattress was designed with air circulation, heat retention and pain relief in mind. The Celliant®-infused cover allows breathing, heat wicking, and is designed to circulate air, improving airflow to keep you cool all night long.

You are a side sleeper or combo sleeper – you’ll probably feel that the Amerisleep Liberty mattress is perfect.

Prefer eco-friendly solutions – The Liberty is constructed with care towards the environment from the patented VPF technology during the manufacturing process and the impact it leaves to the premium bio-plant based materials for better health. It uses thus ECO-friendly materials and processes and is CertiPUR-US® certified.

Amerisleep Liberty bed mattress is not a good match if you

Prefer an innerspring feel – It is not the best option if you love the traditional innerspring feel on a mattress. Instead, Liberty is closer to foam lovers who will love the contouring, plush and support.

Prefer luxury feel –  If you want to invest over $5,000 for a mattress, you can check DUX or at least Tempur-Pedic.  but I guess most people won’t invest just for the brand, actually, we can take a look at for some affordable luxury choices.

Sleeping experience of Amerisleep mattress

While most higher-priced competitors rely on gel-infused foam layers near the top, Amerisleep Liberty mattress uses a unique and superior type of foam compared to standard poly foams. Their Bio-Pur™ memory foam has an extreme open cell structure that lets air move while you’re in bed.

According to the company, this unique material contains a very high percent of plant-based ingredients and is designed for maximum breathability and to retain heat so you’ll stay cool and comfortable through the night.

Based on consumer reviews and our own personal testing, the Amerisleep Liberty Bed indeed sleeps cool and breathes extremely well compared to memory foam mattress we’ve seen so far.

Motion Transfer

The memory foam type used in the Liberty bed helps boost comfort as well as functionality and performance. In addition, our motion transfer test indicates that there is an insignificant motion on the beds making it ideal for couples and it is highly unlikely that you will sense your partner’s moves during the evening.


The Amerisleep Liberty Bed is built in the USA using a high degree of sustainable materials and ecologically sound manufacturing. In particular, the patented foam manufacturing process used by Amerisleep actually leaves air cleaner leaving the factory thanks to filtration and avoiding ingredients with harmful volatile organic compounds.
The company estimates that their mattress has a lifespan of 10 to 12 years, which exceeds other predictions and still provide the same luxury feeling.

Smell and Eco-Friendliness

You will be glad to hear that the Liberty Bed from Amerisleep has almost no smell due to the bed’s construction and delivery approach.

Instead of producing foam in an open environment that emits harmful contaminants into the air, the company manufactures their beds using Variable Pressure Foaming (VPF), the most eco-friendly process in the world.

This VPF process is free of harsh chemicals, creating foam with incredibly low Volatile Organic Compounds (VOCs). Any waste from this process is 100% recycled internally.

Amerisleep’s American-made, plant-based foams are CertiPUR-US® certified, to guarantee it’s completely free from toxic chemicals.
