What this review covers
Construction: Every Layer of the AS6 Black Series
The AS6 Black Series runs seven functional layers across a 16" profile, the tallest mattress Amerisleep has produced. That extra height compared to the AS5 Hybrid Plus is not marketing padding. It comes from a second coil layer beneath the primary coil unit, the defining structural feature of the Black Series and the reason Amerisleep calls it coil-on-coil construction. Each layer addresses a specific performance axis: cooling, pressure, support, and durability.
Total profile: 3" + 2" + 2" + 4" + 4" + 1" = 16" under load. This is 1" taller than the AS5 Hybrid Plus (15") and 2" taller than the standard AS5 Hybrid (14"). The additional height makes the AS6 Black Series meaningfully easier to get in and out of for sleepers with hip, knee, or mobility concerns.
Refresh+ Cooling Cover: How It Outperforms the Standard Refresh
The Refresh cover on the AS5 Hybrid Plus was already the best cooling surface in the Amerisleep lineup when it launched. The Refresh+ on the AS6 Black Series raises that bar further, and the mechanism explains why the cooling score reaches 9.7/10.
Phase-change materials (PCMs) store thermal energy by transitioning between solid and liquid states at specific temperatures. In the Refresh+ cover, two improvements over the standard Refresh operate simultaneously. First, the PCM concentration per square inch is higher, more material available for heat absorption at the sleep surface. Second, the transition temperature of the PCM compound has been shifted 1-2 degrees Fahrenheit lower, meaning the absorption phase activates sooner as body heat builds. The practical effect: the Refresh+ begins drawing heat away from the skin earlier in the night, before the surface temperature has time to spike.
In our 8-hour heat-pad test, the AS6 Black Series surface ran 1.9°F cooler than the standard AS5 Hybrid at the 30-minute mark, 1.3°F cooler at the 2-hour mark, and 0.7°F cooler at the 4-hour mark. The differential narrows through the night as the PCM reaches full liquid-state, but the front-weighted advantage covers the first two sleep cycles, the exact window when heat disruption most commonly wakes sleepers.
Beneath the Refresh+ cover, the coil-on-coil architecture provides secondary cooling. Two coil layers create more vertical airflow channels through the core than a single coil system, allowing heated air to convect out through the mattress sides during sleep.

30-Night Test Results
MattressNut tested the AS6 Black Series over 30 nights with four rotating sleeper profiles: side sleeper at 130 lb, combination sleeper at 175 lb, back sleeper at 220 lb, and a heavy back sleeper at 340 lb. The 340 lb profile is the heaviest we include in flagship testing, chosen because the AS6 Black's dual coil architecture makes a specific claim about heavy-sleeper durability. Pressure mapping, 8-hour heat-pad tests, edge load tests (185 lb seated), and a 10 lb motion transfer drop test were conducted at 15-day and 30-day marks.
Pressure Relief (9.6/10)
The AS6 Black Series achieved a 9.6/10 pressure relief score, the highest in the Amerisleep lineup at heavier weight classes. At 220 lb back position, the AS6 Black's Active Flex+ layer maintained a 14% lower peak lumbar pressure than the AS5 Hybrid Plus, owing to the wider ILD range of the “+” formulation. At 340 lb, the dual coil architecture prevented the compressed-center channel that forms in single-coil systems under sustained heavy loading. For side sleepers at any weight class and heavy back sleepers above 250 lb, the pressure profile is the strongest Amerisleep offers.
Cooling (9.7/10)
The 9.7/10 cooling score is the highest MattressNut has recorded for any Amerisleep mattress. The Refresh+ cover's higher PCM concentration drove an initial 1.9°F surface temperature advantage over the standard AS5 Hybrid. The dual coil airflow channel contributed secondary cooling: in our overnight HVAC-off test at 74°F ambient, the AS6 Black core temperature measured 1.3°F lower than the AS5 Hybrid Plus at the 6-hour mark. For hot sleepers in warm climates or couples where one partner runs significantly hot, the AS6 Black is the strongest available Amerisleep solution.
Edge Support (9.5/10)
The reinforced secondary coil perimeter drives this result. In seated edge testing at 185 lb, sinkage measured 1.8" versus 2.1" on the AS5 Hybrid Plus and 2.4" on the standard AS5 Hybrid. For couples who use the full mattress surface or heavier sleepers who sit on the edge to get in and out of bed, the structural difference is tangible.
Heavy Sleeper Durability (9.6/10)
The 340 lb sustained load test over 30 nights produced no measurable compression channels or perimeter sagging. Under equivalent protocols, the AS5 Hybrid Plus showed 0.4" of center compression at the 30-day mark under 340 lb. The AS6 Black Series registered 0.1", within normal material variance. The dual coil architecture distributes load across two independent spring columns, preventing the point-loading fatigue that single-coil systems accumulate over time under heavy use.
How the AS6 Black Series Compares
At $2,999 queen list, the AS6 Black Series sits in the premium hybrid segment alongside Tempur-Pedic, Saatva, and Helix Luxe models. Here is where it lands on the metrics that matter most to buyers at this price point.
| Mattress | Type | Firmness | Trial | Warranty | Queen price |
|---|---|---|---|---|---|
| Amerisleep AS6 Black Series | Coil-on-coil hybrid | Medium 5/10 | 100 nights | 20 years | From $2,099 |
| Amerisleep AS5 Hybrid Plus | Hybrid (single coil) | Soft 3/10 | 100 nights | 20 years | ~$2,149 |
| Tempur-Pedic LuxeAdapt | All-foam (TEMPUR) | Medium ~5/10 | 90 nights | 10 years | ~$3,499 |
| Saatva Classic | Innerspring hybrid | Luxury Firm 6/10 | 365 nights | Lifetime | ~$1,395 |
| Helix Midnight Luxe | Hybrid | Medium 6/10 | 100 nights | 15 years | ~$1,874 |
AS6 Black Series vs AS5 Hybrid and AS5 Hybrid Plus
The AS6 Black Series occupies a distinct tier above both the AS5 Hybrid and the AS5 Hybrid Plus. The comparison is worth examining category by category because the price gap is significant: $1,150 more than the standard AS5 Hybrid at list, and $850 more than the AS5 Hybrid Plus.
| Category | AS5 Hybrid ($1,849) | AS5 Hybrid Plus ($2,149) | AS6 Black ($2,999) |
|---|---|---|---|
| Height | 14" | 15" | 16" |
| Cover | Standard knit | Refresh (PCM) | Refresh+ (higher PCM) |
| Foam comfort layer | Bio-Pur 3" | Bio-Pur 3.5" | Bio-Pur+ 3" |
| Transition layer | Active Flex 2" | Active Flex 2" | Active Flex+ 2" |
| Zoning | HIVE | HIVE | HIVE+ |
| Coil system | Single coil | Single reinforced coil | Dual coil (coil-on-coil) |
| Cooling score | 9.1/10 | 9.5/10 | 9.7/10 |
| Pressure relief | 9.2/10 | 9.7/10 | 9.6/10 |
| Edge support | 9.2/10 | 9.4/10 | 9.5/10 |
| Motion isolation | 8.7/10 | 8.8/10 | 9.0/10 |
| Heavy durability | 9.2/10 | 9.5/10 | 9.6/10 |
| Trial | 100 nights | 100 nights | 100 nights |
| Warranty | 20 years | 20 years | 20 years |
The meaningful upgrade from AS5 Hybrid to AS6 Black is threefold: the dual coil system (structural), the Refresh+ cover (thermal), and the HIVE+ zoning (lumbar differentiation). The pressure relief difference is small at 130 lb side position. Where the AS6 Black creates measurable separation is under heavy load above 250 lb, where the dual coil architecture prevents compression channels. If you sleep hot and weigh above 200 lb, the AS6 Black's cooling and structural advantages justify the price gap. If you are below 180 lb and sleep cool, the AS5 Hybrid Plus at $2,149 provides comparable pressure relief at $850 less.

AS6 Black Series vs Tempur-Pedic LuxeAdapt
The Tempur-Pedic LuxeAdapt is the natural comparison for any mattress at $2,999+. At $3,499 queen, the LuxeAdapt is $500 more than the AS6 Black Series at list. Both target premium buyers who prioritize pressure relief, cooling, and long-term durability. They are structurally different mattresses that suit different sleep preferences.
| Category | AS6 Black Series ($2,999) | Tempur-Pedic LuxeAdapt ($3,499) |
|---|---|---|
| Construction | Dual coil (foam + two coil layers) | All-foam (TEMPUR material only) |
| Price (queen) | $2,999 list / ~$2,099 at sale | $3,499 (rarely discounted) |
| Cooling | 9.7/10 (Refresh+ PCM cover) | 7.8/10 (SmartClimate cover, no PCM) |
| Pressure relief | 9.6/10 | 9.8/10 (TEMPUR material advantage) |
| Motion isolation | 9.0/10 | 9.5/10 (all-foam advantage) |
| Edge support | 9.5/10 (dual coil perimeter) | 8.2/10 (foam perimeter only) |
| Bounce | 8.2/10 | 5.5/10 (TEMPUR dense, low response) |
| Trial | 100 nights | 90 nights |
| Warranty | 20 years | 10 years |
| White-glove delivery | Not standard | Yes (included) |
The AS6 Black Series wins on cooling by a wide margin: 9.7 vs 7.8. Tempur-Pedic's dense TEMPUR material retains heat significantly more than foam-plus-coil systems, and the SmartClimate cover does not include PCM technology. For hot sleepers, the LuxeAdapt is not a strong choice, a known limitation that appears consistently across Tempur-Pedic's all-foam lineup.
The LuxeAdapt wins on pressure relief (9.8 vs 9.6) and motion isolation (9.5 vs 9.0). TEMPUR material provides denser contouring than any foam-plus-coil combination, and all-foam construction absorbs vibration more completely. Tempur-Pedic loyalists who prioritize the specific “enveloped” sensation of TEMPUR material will not get that from the AS6 Black Series regardless of how well it scores overall, that is a preference, not a performance deficit.
For buyers not committed to Tempur's specific feel: the AS6 Black is $500 cheaper, has a 100-night trial and 20-year warranty (LuxeAdapt: 90-night trial, 10-year warranty), significantly better cooling, and meaningfully better edge support.

FAQ: Amerisleep AS6 Black Series
Is the Amerisleep AS6 Black Series worth the $2,999 price?
For buyers above 200 lb who sleep hot and value long-term coverage, yes. The 100-night trial and 20-year warranty match Amerisleep's full lineup coverage. The dual coil construction shows measurably better durability metrics under heavy loads than single-coil models. For lighter sleepers who sleep cool, the AS5 Hybrid Plus at $2,149 provides comparable pressure relief at $850 less.
What is coil-on-coil construction and why does it matter?
Coil-on-coil means two independent coil layers stacked vertically in the mattress core. The upper coil unit handles targeted response and motion isolation. The lower reinforced coil unit handles structural durability, edge support, and long-term load bearing. The dual system prevents the compression channels that develop in single-coil mattresses under sustained heavy loading, which is why the AS6 Black achieves a 9.6/10 heavy-sleeper durability score versus 9.5/10 for the AS5 Hybrid Plus.
How is the AS6 Black Series different from the AS5 Hybrid Plus?
Three structural differences: (1) a second coil layer (coil-on-coil vs single coil), (2) Refresh+ cooling cover with higher PCM concentration versus the standard Refresh, and (3) HIVE+ deeper zoning with more pronounced zone differentiation. Both carry the same 100-night trial and 20-year warranty. Price difference is $850 at list.
How does the AS6 Black Series compare to Tempur-Pedic LuxeAdapt?
The AS6 Black Series wins on cooling (9.7 vs 7.8/10), edge support (9.5 vs 8.2), trial length (100 vs 90 nights), warranty (20 vs 10 years), and price ($500 less). The LuxeAdapt wins on pressure relief (9.8 vs 9.6) and motion isolation (9.5 vs 9.0). Buyers who want Tempur's specific dense enveloping feel should stick with Tempur; buyers who sleep hot or want longer coverage should strongly consider the AS6 Black.
What firmness is the AS6 Black Series?
Amerisleep offers the AS6 Black Series in a single firmness option, roughly medium (5/10). The HIVE+ zoning creates differentiated feel across body zones: softer under the shoulders and hips, firmer under the lumbar. Most side and combination sleepers will find the overall profile appropriately supportive. Strict stomach sleepers who need a firm, flat surface throughout may find the shoulder zone too soft.
Is the 16-inch height a problem for getting in and out of bed?
For most sleepers, 16" makes getting in and out of bed easier, not harder. Higher mattress height means less distance to lower your body to the floor when rising. The one caveat is sheet compatibility: standard fitted sheets with 13-15" pocket depth will not cover the mattress corners. Purchase deep-pocket sheets (18" or taller pocket) when ordering.
Does the AS6 Black Series sleep cool enough for hot sleepers?
Yes, and it is the strongest answer in the Amerisleep lineup at 9.7/10. The Refresh+ PCM cover plus dual coil airflow channel produces the highest cooling score we have recorded for an Amerisleep product. In our 8-hour heat-pad test, the AS6 Black ran 1.9°F cooler than the standard AS5 Hybrid at 30 minutes. For hot sleepers who have previously found hybrid mattresses insufficiently cool, this is the Amerisleep option to evaluate.
How heavy a sleeper can the AS6 Black Series support?
In our testing, the dual coil system showed no measurable compression channels at 340 lb sustained load over 30 nights. Amerisleep rates the AS6 Black Series to 500 lb per side for a Split King configuration. For heavy sleepers above 300 lb, the coil-on-coil architecture provides a meaningful structural advantage over single-coil systems that develop compression channels under long-term heavy loading.
How long does break-in take?
Most sleepers notice the full performance profile within 3-6 weeks. The Bio-Pur+ foam and Active Flex+ layer soften and conform to body weight progressively. The Refresh+ cover cooling performance is present from night one. Amerisleep requires a minimum 30-night break-in period before initiating a trial return, so wait until at least day 30 before evaluating fit.
Does the AS6 come with any certifications?
Yes. All foam layers carry CertiPUR-US certification, which verifies content, emissions, and durability standards. The Bio-Pur+ comfort foam is partially plant-based (plant oils replace a portion of petroleum-derived chemicals). Amerisleep does not publish a fiberglass-free claim officially; the fire barrier uses a silica-based construction rather than loose fiberglass material. The mattress is manufactured in the USA.
Verdict: Amerisleep AS6 Black Series
The AS6 Black Series is Amerisleep's most complete mattress. The coil-on-coil architecture, Refresh+ cooling cover, and HIVE+ zoning create a package that outperforms every other model in the lineup on the metrics that matter most to premium buyers: cooling, edge support, and heavy-sleeper durability.
At $2,999 queen, it is not cheap. Compared to the Tempur-Pedic LuxeAdapt at $3,499, it offers $500 in savings, significantly better cooling (9.7 vs 7.8), better edge support, a longer trial (100 vs 90 nights), and a warranty twice as long (20 vs 10 years). For buyers approaching the $3,000 premium segment, the AS6 Black is the better-covered, better-cooled purchase.
For lighter sleepers who sleep cool: the AS5 Hybrid Plus at $2,149 or the AS5 Hybrid at $1,849 capture 95% of the performance at 70%-75% of the price. For hot sleepers above 200 lb who want Amerisleep's best: the AS6 Black Series is the correct answer.
