Amerisleep Bio-Pur® vs Traditional Memory Foam
Bio-Pur® is the perfect answer to a better bed. Available in every Amerisleep mattress, we engineered Bio-Pur® to deliver cooling comfort, responsive support, and healthier sleep.
Breathable & Cooling
Unlike the dense construction of traditional memory foam, Bio-Pur®'s large, open-cell structure has a few distinct advantages:
- Allows air to flow freely
- Prevents heat build-up
- Perfect for hot sleepers
Responsive & Supportive
With traditional memory foam, the slow response time can feel like you're sleeping in quicksand. This leads to discomfort and poor spinal alignment. Here's how Bio-Pur® is different:
- Contours to your body
- Relieves painful pressure points
- Provides cushioning and support
- Bounces back in just seconds
Eco-Friendly Materials
While traditional memory foam is 100% petroleum-based, Bio-Pur® is partially made with renewable plant-based oils. This minimizes our reliance on non-renewable resources and ensures our products are better for you and the planet.

A Healthier Sleep
Many memory foams you see today use harsh chemicals such as benzene, formaldehyde, and more that can cause unpleasant off-gassing.
Bio-Pur®, on the other hand, is:
- CertiPUR-US® certified
- Low in volatile organic compounds (VOCs)
- Naturally resistant to dust mites, mold, and mildew
- Made without formaldehyde, ozone depleters, prohibited phthalates, PBDEs, mercury, lead, and other heavy metals
Decades of Durability
Most memory foams only last 7 to 10 years. Some deteriorate within 3 to 5 years. Longer lifespans are only available in higher-end memory foam.
We build our mattresses to last. With Bio-Pur®, you get:
- An industry-leading 20-year warranty
- Protection against indentations and sagging

Frequently Asked Questions
What mattress is best for me?
Choosing the right mattress is largely a matter of understanding what firmness and feel you enjoy, along with what can complement your sleeping position and body type. How you lie down influences how your body will need to be supported, with back and stomach sleepers requiring firmer feels than side sleepers do.
To simplify shopping matters, we offer a Mattress Fit Quiz with a recommendation tailored to your sleep position, body type, and personal preferences.
Which mattress is best for back pain?
A balanced feel is key when choosing a mattress for back pain. A too-soft mattress can cause the user to sink too far into the bed, leading to more pain. Conversely, a too-firm mattress can leave no room for the heavier parts of the body to sink in, letting pressure build up along the back area.
We suggest a medium or medium-firm mattress as the best mattresses for back pain because of their even support and balanced cushioning feel. Try one of our AS3 mattresses or the Organica if you're looking for a mattress with natural materials.
What mattress types are the most comfortable?
Every type of mattress has the potential to be someone's most comfortable mattress, although some types do have a better success rate than others. Memory foam mattresses have exploded in popularity due to the swift way they meet the body's curves, leaving no part unsupported and eliminating pressure points.
Latex mattresses possess a similar feel to memory foam mattresses, though the buoyancy of latex does create a subtly different contour to its surface. Hybrid mattresses are bouncier than all-foam mattresses, establishing a weightless feel when sleepers stretch out on the surface.
Traditional innerspring mattresses have developed a reputation for being uncomfortable due to a lack of contouring. The thinly padded tops of an innerspring mattress can't hug the body the way a foam or hybrid mattress can, letting pressure build up into morning aches and pains.
What is the best mattress for side sleepers?
Mattresses with thick comfort layers and ample amounts of cushion are the bed of choice for side sleepers. A too-firm mattress with little cushion can let pressure build up in the shoulders and hips, causing morning stiffness and achiness. Medium to soft mattresses provide plenty of pressure-relieving cushion while still supporting the spine's neutral alignment.
We recommend the AS3, AS5, or Organica mattresses for side sleepers.
What is the best mattress for hot sleepers?
An Amerisleep mattress can be an excellent choice for hot sleepers due to the wide array of cooling materials we take advantage of when designing our mattresses. Our mattresses feature Refresh fabric covers, a material that transforms body heat into infrared energy for better cooling and recovery. We also rely on Bio-Pur® foam for comfort, a material engineered for greater sustainability and coolness.
The hybrid mattresses we offer feature the same plant-based memory foam and Refresh fabric as our memory foam beds, plus supportive pocketed coils that enable greater airflow. We also offer a latex mattress perfect for hot sleepers. The Organica has heat-wicking cotton and wool paired with cool latex foam and airy coil support.
