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 Active Flex in the AS5?

Active Flex is a unique material we use to minimize sinkage without compromising the bed’s softness. The material’s buoyancy keeps you from sinking so far into an AS5 mattress that you misalign your spine. Both the classic AS5 memory foam mattress and the newer AS5 hybrid rely on Active Flex to create a plush and supportive surface.

 
Can the AS5 work with an adjustable bed frame?

Yes, the AS5 mattress can work with an adjustable bed frame, just like any other mattress we offer. While the AS5 is our thickest mattress with its 14-inch height, it’s not so thick that it can’t flex and bend with an adjustable base’s movements. If you’re interested in pairing the AS5 with an adjustable bed, you might want to take advantage of our adjustable bed package, which offers both at a discounted price.

 
How much does the AS5 weigh? The AS5 Hybrid?

Our AS5 mattresses are the thickest and heaviest beds we offer. The classic AS5 memory foam mattress weighs as follows:

  • A twin size memory foam mattress is 53 pounds
  • A twin XL size memory foam mattress is 57 pounds
  • A full size memory foam mattress is 73 pounds
  • A queen size memory foam mattress is 88 pounds
  • A king size memory foam mattress is 111 pounds
  • A California king size memory foam mattress is 110 pounds

The AS5 hybrid is even heavier than the original AS5:

  • A twin size hybrid mattress is 71 pounds
  • A twin XL size hybrid mattress is 80 pounds
  • A full size hybrid mattress is 97 pounds
  • A queen size hybrid mattress is 113 pounds
  • A king size hybrid mattress is 143 pounds
  • A California king size hybrid mattress is 142 pounds
 
Who are soft mattresses good for?

A soft mattress is well suited for side sleepers and petite individuals. This type of bed cushions them and conforms to their bodies for pressure relief.

Conversely, a soft mattress is not a good choice if you are an average-size or plus-size back or stomach sleeper. When these sleepers lie on a soft mattress, they’re likely to sink too far and misalign their spine.

Plus-size sleepers should be cautious when considering a soft mattress. While our AS5 model has supportive features to keep a person from sinking into the mattress, many soft mattresses do not have similar features.

 
How does the soft AS5 feel in terms of support?

We carefully designed our AS5 mattresses to balance an undeniable soft feeling with supportive features:

  • The top layer of Bio-Pur® foam feels plush, yet it’s also adaptable enough to adjust with your every movement within seconds.
  • The next layer, Active Flex, keeps you from sinking too far into the AS5 without negating the soft top layer.
  • The original AS5 memory foam mattress has a supportive transition layer and base layer. The transition layer is Affinity foam with HIVE® technology, which is separated into five zones with a supportive feel in the head, back, and feet sections. The base layer is durable Bio-Core® foam.
  • The AS5 hybrid has a supportive coil base that offers responsive back support. The coils in the mattress are lifting and offer flexible cushioning, so they promote healthier spinal alignment and prevent sleepers from sinking in the bed.
