Amerisleep AS6 Black Series Review 2026: Who Should Buy It

The Amerisleep AS6 Black Series is the brand’s luxury foam flagship, built around one clear promise: deep pressure relief without the heat buildup memory foam is known for. At a 14-inch profile, it layers a CryoCool cover, a titanium-infused TitanAir foam and mineral-infused ArcticWave cooling bands over Bio-Pur memory foam, then backs the whole thing with a 20-year warranty. It is a mattress aimed at sleepers who want a plush, cushioned surface and are willing to pay for active temperature control. This review covers how the three firmness options actually feel, who each one suits, what the trial and warranty terms mean in practice, and where the AS6 stops being the right choice.

Who is the Amerisleep AS6 Black Series for?

The AS6 Black Series suits sleepers who want a soft, pressure-relieving surface and care about sleeping cool on an all-foam build. It is designed to support all sleep positions, and the brand positions it for couples who want a luxury feel with targeted support at key pressure points. If you sink into foam and want the surface to cradle your hips and shoulders, this is the profile Amerisleep built.

Three firmness options widen the fit considerably. The Plush Soft option carries a 3/10 firmness rating and is described as delivering deep pressure relief for side sleepers. The Luxury Firm option rates 7/10 and is aimed at back sleepers and couples with different firmness preferences. The Firm option rates 8/10 and is recommended for back sleepers seeking spinal alignment. That spread means the AS6 is not a single-feel mattress, and your choice of comfort level matters more than the model name itself.

The mattress is CertiPUR-US certified and OEKO-TEX Standard 100 certified, with materials tested free from harmful substances including fiberglass. It is made in the USA and ships free; returns are free once the mattress has been kept at least 30 nights. Those certifications matter to shoppers who want to know what the foam is made of before committing to a 14-inch all-foam bed.

What are the AS6 Black Series specifications?

The core numbers are straightforward: a 14-inch profile height, three firmness options, a 100-night trial (returns accepted only after the first 30 nights), a 20-year warranty, and free shipping. Amerisleep lists the queen size at 60 by 80 inches. The firmness scale runs 3/10 for Plush Soft, 7/10 for Luxury Firm, and 8/10 for Firm.

How does the AS6 Black Series feel?

The feel depends entirely on which comfort level you order, and the three options are far from variations on one theme. Plush Soft at 3/10 is a genuinely soft mattress: the plush surface enhances cushioning and the goal is deep pressure relief at the hips and shoulders for side sleepers. Luxury Firm at 7/10 is the middle path, described as a perfect balance of plush comfort and uplifting support, with targeted support at key pressure points. Firm at 8/10 gives robust support with a balanced touch of comfort, promoting spinal alignment for back sleepers.

Underneath the cover, Bio-Pur memory foam is the primary comfort layer. Amerisleep describes it as enhancing airflow and adapting to the body for customized comfort, with instant pressure relief. This is a foam mattress in the classic sense: you will feel the surface conform to your shape rather than resting on top of a spring system. Combination sleepers are accommodated too, since the brand states the mattress is designed to support all sleep positions and adapts to your movements through the night.

The 14-inch profile puts the AS6 in the luxury height range, which matters if you have existing sheets or a specific bed frame height in mind. A taller mattress generally means more comfort layers stacked above the support core, and the AS6 uses that space for its cooling stack as well as its pressure relief foam.

What cooling technology does the AS6 use?

Cooling is the AS6’s headline feature, and Amerisleep calls it Triple-Cooling Technology. Three separate components work together. The CryoCool cover uses advanced fibers for an immediate cool-to-touch sensation and actively removes heat on contact. The TitanAir layer is a titanium-infused memory foam that disperses heat efficiently while offering responsive pressure relief. Amerisleep says its mineral-infused ArcticWave cooling bands continuously maintain sleep temperature throughout the night.

This is a layered approach rather than a single gimmick. The cover handles the first few seconds when you get into bed, the foam layer deals with heat that builds up as you sleep, and the bands work over the full night. For sleepers who have tried memory foam before and given up because it trapped heat, this is the specific problem the AS6 is engineered against. The brand also lists enhanced cooling as a headline feature of the model alongside its customizable feel.

What do the trial and warranty actually cover?

The AS6 Black Series comes with a 100-night trial and a 20-year warranty. The warranty covers material durability and craftsmanship, which means defects in how the mattress is built and in the materials themselves. Amerisleep accepts a return only after the first 30 nights; between night 30 and night 100, sending the mattress back does not carry a shipping charge.

A 100-night trial is shorter than some competitors offer, so it is worth knowing before you buy. That is still more than three months of sleep, which is enough time to adjust to a new foam feel, but shoppers who like a longer runway before committing may want to factor that in. The 20-year warranty is a substantial term for a foam mattress and signals confidence in the durability of the materials.

How much does the Amerisleep AS6 Black Series cost?

Amerisleep lists the AS6 Black Series across the standard size range, with the queen size measuring 60 by 80 inches. Shipping is free, and returns are free after the first 30 nights.

What you are paying for at this tier is the cooling stack, the 14-inch build, the certification standards, and the 20-year warranty. The AS6 sits at the top of the Amerisleep lineup as the Black Series flagship, so it carries the brand’s most advanced temperature control features. If cooling is the reason you are looking at a foam mattress in the first place, that is where the budget goes.

Who should NOT buy the Amerisleep AS6 Black Series?

The AS6 is not the right choice for every sleeper, and the gaps are worth stating plainly.

• Shoppers who want a longer trial. The 100-night trial is the shortest term in this comparison set, so buyers who want six months or more to decide should look at alternatives with longer windows.
• People who prefer sleeping on top of the mattress. This is an all-foam build with a conforming feel. If you want a floating, on-top sensation rather than contouring, a coil or hybrid construction will suit you better.
• Buyers on a tight budget. The AS6 is Amerisleep’s luxury flagship with a triple-cooling system. Shoppers who want the brand’s foam feel without the premium cooling stack should consider a lower tier in the range.
• Anyone who has not chosen a firmness yet. The three options range from 3/10 to 8/10, which is a wide spread. Ordering without knowing which profile you need risks a mattress that feels wrong on night one.

Is the Saatva Classic a better alternative?

The Saatva Classic takes a different route to comfort: a dual-coil innerspring with a 3-inch Euro pillow top instead of an all-foam build. Where the AS6 uses foam layers to contour and cool, the Saatva Classic uses over 1,000 recycled carbon steel coils in full size and up, tempered three times for durability, with a breathable organic cotton cover. The construction difference is fundamental, and it changes how the mattress feels under you.

The Saatva Classic offers three comfort levels of its own: Plush Soft at 3/10, Luxury Firm at 5-7/10, and Firm at 8/10. Its Lumbar Zone technology targets spinal alignment, and the brand describes the mattress as chiropractor approved. Both mattresses carry an endorsement from the American Chiropractic Association, so that credential does not separate them.

Where the Saatva Classic pulls ahead is in trial length and warranty term. It comes with a 365-night home trial compared to the AS6’s 100 nights, and a lifetime warranty compared to 20 years. Free white-glove delivery includes in-room setup and removal of your old mattress at no additional cost. For shoppers who value a coil feel, a longer trial, and a longer warranty, the Saatva Classic is the stronger fit. For sleepers committed to an all-foam build with active cooling, the AS6 remains the better match.

World Sleep Almanac score: 8.2/10

The World Sleep Almanac editorial score for the Amerisleep AS6 Black Series is 8.2/10, based on five criteria: price at equivalent size, trial and returns, warranty, materials and construction, and public customer reviews. The rating is an editorial judgment drawn from those criteria, not a hands-on test result.

• Materials and construction: strong. CertiPUR-US certified foams, OEKO-TEX Standard 100 certification, fiberglass-free materials, and a triple-cooling stack give the AS6 a premium build sheet.
• Warranty: solid. Twenty years covering material durability and craftsmanship is a long term for an all-foam mattress.
• Trial and returns: adequate. 100 nights, with free returns once you have slept on it 30 nights, is a fair window, though shorter than the 365 nights offered by Saatva.
• Public reviews: strong. Amerisleep lists the range at 15,000-plus reviews with an average of 4.7 stars.
• Price at equivalent size: mid-to-high. As the Black Series flagship with active cooling, it sits at the top of the brand’s pricing.

Frequently asked questions

Which AS6 firmness option should I choose?

Pick Plush Soft at 3/10 if you sleep on your side and want deep pressure relief at the hips and shoulders. Choose Luxury Firm at 7/10 if you sleep on your back or share the bed with a partner who has different firmness preferences. Go with Firm at 8/10 if you want robust support and spinal alignment on a firmer surface. The right choice depends on your primary sleep position, not on which option is most popular.

Does the AS6 Black Series sleep cool?

Cooling is the central design goal of this mattress. Three components work together: the CryoCool cover gives an immediate cool-to-touch sensation, the TitanAir titanium-infused foam disperses heat, and the ArcticWave mineral-infused bands maintain temperature through the night. Amerisleep brands this as Triple-Cooling Technology, and it is the feature that distinguishes the Black Series from a standard memory foam mattress.

How long is the trial period for the AS6?

The AS6 Black Series comes with a 100-night trial and free shipping. Amerisleep accepts returns only after the first 30 nights, so plan on at least a month of sleep before deciding. It is a shorter window than the 365-night trial Saatva offers, so factor the trial length into your decision if you like a long evaluation period before committing.

Is the Amerisleep AS6 fiberglass-free?

Yes. Amerisleep states that all materials in the AS6 Black Series are tested and confirmed free from harmful substances, including fiberglass. The foams are CertiPUR-US certified and the materials carry OEKO-TEX Standard 100 certification, so the build is verified against both standards.

What does the 20-year warranty cover?

The warranty covers material durability and craftsmanship, which means defects in the materials used and in how the mattress is constructed. It runs for 20 years from purchase. This is a substantial term for an all-foam mattress and reflects the brand’s confidence in the longevity of the foam layers and cooling components.

Verdict

The Amerisleep AS6 Black Series is a strong buy for sleepers who want a luxurious, pressure-relieving foam mattress with genuine cooling technology and a long warranty. Its triple-cooling system addresses the main complaint about memory foam, the three firmness options cover side, back and combination sleepers, and the certifications confirm a clean, fiberglass-free build. The 100-night trial is the one term to weigh carefully, since it is shorter than what competing luxury brands offer. If you want an all-foam mattress with active temperature control and a 20-year warranty, the AS6 delivers on that brief. If you prefer a coil feel, a longer trial, or a lifetime warranty, the Saatva Classic is the alternative worth considering instead.
