Experience Bio-Pur®:
Eco-Friendly, Cooler 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.

Memory foam lovers say Bio-Pur® is a huge upgrade, while critics admit it solves all the problems of traditional memory foam. Plus, since our beginnings in 2009, we've proudly manufactured Bio-Pur® in the USA.

Bio-Pur® vs Traditional Memory Foam

Breathable & Cooling

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

Unlike traditional memory foam, Bio-Pur® has a rapid response time that:

  • Relieves painful pressure points
  • Prevents heat build-up
  • Bounces back in just seconds

Eco-Friendly Materials

Featuring renewable plant-based oils, Bio-Pur® helps us:

  • Minimize use of non-renewable resources
  • Prevents heat build-up
  • Produce products that are better for you and the planet

A Healthier Sleep

The surface you sleep on is important. That’s why Bio-Pur® is:

  • CertiPUR-US® certified & low in VOCs
  • Resistant to dust mites, mold, and mildew & made without harsh chemicals

Traditional memory foams miss the mark when it comes to cooling and responsiveness. Amerisleep’s proprietary Bio-Pur® memory foam is an eco-friendly alternative that blends contouring comfort with buoyant support and superior breathability to help you get your best night’s sleep yet.

Our plant-based Bio-Pur® is significantly more breathable and responsive than traditional memory foam. It snaps back to its original shape in seconds, so it’ll never cause you to uncomfortably sink, and it’s significantly more porous and airy, so you won’t have to worry about night sweats. Even better? Bio-Pur® contains a fraction of the petrochemicals used in other memory foams, so it’s less likely to off-gas and is completely free of harmful substances.

That’s why in over 15,000 reviews, our mattresses rate 4.7 out of 5 stars and why 98% of customers would recommend us to a friend.

Free Shipping

Amerisleep Mattresses come with free shipping within the continental US. We ship our mattresses direct to your home and compressed in an eco-friendly box using FedEx. And in most cases, they arrive in two weeks or less.

Please note: All our products ship separately, so if you’ve ordered a foundation, base, sheets, or any other sleep accessories to go with your new mattress, they may arrive sooner or later than your Amerisleep mattress. But don’t worry, shipping is always free.

 
20-Year Warranty

Amerisleep mattresses are backed by an industry-leading 20-year warranty. For the first 10 years, we will replace your mattress if you encounter any defects, including sagging greater than 0.75”. And for the second 10 years, we will offer you a prorated replacement.

 
Compatibility

Our mattresses are compatible with a variety of bed frames and bases.

Mattress Foundations
Our memory foam and hybrid mattresses are best supported on solid or slatted mattress foundations. Slatted bases should have slats no more than 3 inches apart — we even sell our Amerisleep Mattress Foundation designed to pair perfectly with our mattresses.

Platform Beds
Platform beds have a solid or slatted base, so they can provide proper support for our mattresses. If you have a platform bed with large gaps between slats, we suggest buying extra slats or a bunkie board to create a sturdier surface for your mattress and meet warranty guidelines.

Adjustable Bed Frames
Both our memory foam and hybrid mattresses work well with adjustable bed frames. They’re adaptable and flexible, so they can move with the base without becoming damaged or worn. We even sell two adjustable bed frames to pair with our beds: the Amerisleep Adjustable Bed and the Amerisleep Adjustable Bed+.

While our mattresses can work with most bed frames and foundations, it’s not compatible with absolutely every type of mattress support — namely box springs.

Box Springs
Box springs are best paired with innerspring mattresses, and since innerspring beds were the most common for many years, a lot of us have box springs at home. Box springs contain coils within and as a result, are bouncy. Beds with foam layers can experience premature wear, tear, and unexpected damage when paired with one of these because they do not offer the even, sturdy support foam beds need.

Frequently asked questions

 
What is HIVE® technology in the AS2? How does it help with back pain?

The Affinity layer with HIVE® technology acts as a transition layer in the AS2 mattress. Not only does the material limit sinkage so a person doesn’t bottom out on the support layer, it also offers five zones of targeted support.

Hexagonal cutouts across the second layer’s surface comprise the bed’s HIVE® technology. Under the shoulders and hips, these cutouts flex and create a conforming cushion. Under the head, torso, and feet, these cutouts remain firm and provide uncompromising support.

HIVE® is found not only in the memory foam version of the AS2 but also in our AS3, AS4, and AS5 memory foam mattresses.

 
Who are medium-firm mattresses good for?

Medium-firm mattresses are excellent for back and stomach sleepers. The surface offers just enough cushion to contour to the body for pressure and pain relief, while its firm support ensures the spine won’t shift out of alignment.

A medium-firm mattress may also feel supportive and comfortable if you’re a heavyset side sleeper, though a medium mattress like our AS3 may feel better.

 
Is the AS2 eco-friendly?

Yes, our AS2 memory foam and hybrid mattresses are eco-friendly. We make our Bio-Pur® foam, which is the top layer in our memory foam and hybrid mattresses, with plant-based oils for a cooler, more sustainable, and more responsive material.

Every layer of foam we use in our mattresses is certified safe by CertiPUR-US®, an independent organization with the goal of ensuring foam is produced without dangerous or toxic materials.

 
What’s better: the AS2 or AS2 Hybrid?

Both the original memory foam mattress and the newer hybrid model are excellent choices for back and stomach sleepers.

If you’re debating between the two, ask yourself if you prefer a bed that molds to your body for a cradling feel, or the buoyancy of an “on top of the mattress” feeling? If you prefer the first, then choose the classic AS2 mattress. Those who would rather have the second should try the AS2 Hybrid.

 
How soft does the AS2 feel?

The AS2 doesn’t feel very plush, though its top layer of Bio-Pur® foam still conforms to a person’s body for pressure relief. That’s why we typically don’t recommend the AS2 mattress for people who need a soft bed to sleep well, such as average-sized side sleepers and petite individuals. The medium-firm feel of our AS2 provides the support back and stomach sleepers need.
