Find your best fit

Start with your buying decision

Start with these listed features, advertised feel, and seller terms, then consider how they fit your preferences. The detailed comparison below covers shared features, differences, and questions to confirm before choosing either mattress.

The literal difference: firmness tuning

Amerisleep AS6 Black Series Luxury Firm
Luxury Firm; Amerisleep firmness rating 7/10
Amerisleep AS6 Black Series Plush Soft
Plush Soft; Amerisleep firmness rating 3–4/10

Why it matters: Luxury Firm keeps the hips higher and makes turning easier, which suits back sleepers, many stomach sleepers, and people who dislike a deep cradle. Plush Soft lets the shoulder and hip settle much farther into the comfort system, which benefits side sleepers and shoppers who feel pressure on firmer surfaces. The large firmness gap matters more than any shared feature.

Surface response

Amerisleep AS6 Black Series Luxury Firm
Support-forward with moderate surface cushioning
Amerisleep AS6 Black Series Plush Soft
Deeply cushioned with substantially more shoulder and hip sink

Why it matters: This is the choice you will notice most. A firmer tune limits how far the hips and shoulders settle before the support system engages; a softer tune lets those areas sink farther into the comfort stack. Neither response is an upgrade by itself—the better one is the feel that keeps you comfortable without making movement feel difficult.

Cooling system

Amerisleep AS6 Black Series Luxury Firm
CryoCool cover, TitanAir titanium-infused foam, and ArcticWave cooling bands
Amerisleep AS6 Black Series Plush Soft
The same CryoCool, TitanAir, and ArcticWave system

Why it matters: Both mattresses deliver Amerisleep's full three-part AS6 cooling package. Warm sleepers do not need to select one of these feels to unlock an extra cooling layer. Choose firmness for comfort and alignment, then judge the shared cooling system during the home trial.

Which one fits you

Our buying recommendation

Buy AS6 Luxury Firm for easier movement, stronger resistance under the hips, and a support-forward feel that fits back and combination sleeping. Choose AS6 Plush Soft when a deep cushion is the goal, especially for side sleepers who want more room at the shoulder and hip. Neither is a higher tier: both cost $2,649, use the same 14-inch cooling hybrid construction, and carry the same direct comfort guarantee. The right answer is whether you want a 7/10 surface or the much softer 3–4/10 alternative.

Amerisleep AS6 Luxury Firm vs Plush Soft: The Feel Is the Difference

AS6 Luxury Firm and AS6 Plush Soft cost the same $2,649 for a Queen and use the same 14-inch hybrid construction: CryoCool cover, TitanAir titanium-infused foam, ArcticWave cooling bands, Bio-Pur comfort foam, Affinity transition foam, a 6-inch PrecisionCoil unit, and a 1-inch BaseGuard foundation. The literal difference is how firmly the comfort layers are tuned. Choose the surface that holds your body in its most comfortable position; there is no higher-priced model to chase here.

Comfort and transition materials

Amerisleep AS6 Black Series Luxury Firm
Bio-Pur comfort foam over Affinity transition foam
Amerisleep AS6 Black Series Plush Soft
The same Bio-Pur and Affinity material families, tuned to the other firmness

Why it matters

Both choices use the same named foams, so the decision is about how those materials are calibrated rather than one model containing a premium foam the other lacks. Select the amount of surface give you want instead of assuming a softer or firmer label means less mattress.

Coil support and height

Amerisleep AS6 Black Series Luxury Firm
14 inches; 6-inch PrecisionCoil unit plus 1-inch BaseGuard
Amerisleep AS6 Black Series Plush Soft
The same 14-inch profile, PrecisionCoil unit, and BaseGuard foundation

Why it matters

Both provide the same pocketed-coil support architecture, airflow space, responsive movement, and finished height. Couples and edge sleepers keep the AS6 support system with either feel, and existing sheets or foundations will fit both the same way.

Queen price and buying confidence

Amerisleep AS6 Black Series Luxury Firm
$2,649 current / $3,649 regular; 100-night Amerisleep trial; 20-year warranty
Amerisleep AS6 Black Series Plush Soft
The same current price, regular price, direct trial, and warranty

Why it matters

Price does not break the tie. Amerisleep asks direct buyers to try the mattress for at least 30 nights, then offers free professional pickup and a full refund during the 100-night mattress trial. Another retailer's comfort guarantee controls when that seller supplies the offer, so check the seller named on the shopping button.

Who benefits from each mattress?

Use the differences above to match the mattress to the way you sleep. Each model has a clear reason to buy. When one costs less, choose it if it already delivers the feel, support, and temperature control you want. Pay more when the added material or feature gives you a benefit you expect to notice every night.

Choose Amerisleep AS6 Black Series Luxury Firm if:

  • Choose Luxury Firm when you sleep on your back, rotate positions, or want the mattress to resist deeper hip sink.
  • Pick it when easy movement and a support-forward surface matter more than a pronounced plush cradle.
  • Buy Luxury Firm when partners need a stable middle ground; it keeps every AS6 cooling and coil feature at the same price as Plush Soft.

Choose Amerisleep AS6 Black Series Plush Soft if:

  • Choose Plush Soft when you sleep mainly on your side and want noticeably more cushion around the shoulder and hip.
  • Pick it when lighter body weight or a strong preference for softness makes firmer beds feel unwelcoming.
  • Buy Plush Soft when deep surface give is a benefit rather than an obstacle to movement; it includes the same AS6 cooling and coil systems for the same price.

Published construction details and claims are from Amerisleep's current AS6 construction, firmness, price, and comfort-trial specifications. SleepRanked verified the exact AS6 feel options, shared construction, Queen prices, and direct trial terms on September 12, 2026. Cooling descriptions are Amerisleep claims. The direct trial applies when Amerisleep supplies the offer; another retailer's comfort guarantee replaces it when that retailer supplies the purchase link.
