Amerisleep AS6 Black Series Mattress Reviews (2026)

The AS6 Black Series is a compelling choice if you want a foam-forward luxury mattress without giving up the alignment and perimeter stability of coils. The Luxury Firm model cushioned the shoulders and hips while keeping the pelvis level, and its quiet surface contained partner movement exceptionally well. The CryoCool cover also felt cooler on contact than a typical foam top, though it naturally became warmer after prolonged contact.

Its personality is closer to a memory-foam mattress than a springy hybrid. That makes it especially well suited to back sleepers, side sleepers, couples, and hot sleepers who value contouring over bounce. Frequent position changers may find the slow recovery restrictive. Strict stomach sleepers should consider the Firm version rather than the softer choices.

Who it's for:

• Back and side sleepers who want close contouring without deep hip sink
• Couples who are easily disturbed by movement
• Hot sleepers who prefer the feel of memory foam

Who should look elsewhere:

• Sleepers who want a buoyant, fast-moving surface
• Strict stomach sleepers considering Plush Soft or Luxury Firm
• Shoppers who do not need premium cooling materials

We used the Luxury Firm model for back and side sleeping over several weeks. Alongside nightly use, we checked spinal support and pressure relief with weighted sink measurements, tracked surface temperature during extended rest, and repeated controlled movement drills to assess motion isolation. We also measured edge compression and timed foam recovery to judge responsiveness. Our full mattress testing process explains how these checks translate into scores.

Our sample reached its advertised 14-inch height after 48 hours and was used for 21 nights. At 5 feet 10 inches and 175 pounds, I rated the Luxury Firm a 6 out of 10 for firmness. On my back, the foam filled the curve above my hips without letting my pelvis tilt. On my side, a 44-pound load sank 1.6 inches at the shoulder area and 1.1 inches near the center, which matched the deeper cushioning I felt around my shoulder without a loose sensation under my waist.

The cover felt distinctly cool when I first lay down. During a 30-minute temperature check in a 70°F room, the surface rose from 71.8°F to 79.4°F, then returned to within 2.1°F of its starting temperature 10 minutes after I got up. Marcus, our hottest sleeper, still noticed some warmth during long, motionless stretches, but the bed never developed the stuffy feel common to dense foam. That result supports the 4.5/5 cooling score without suggesting that the surface stays cold all night.

Motion isolation was even more convincing. In three drops with a 10-pound ball from 6 inches, a sensor 4 feet away recorded an average peak acceleration of 0.08 g, and visible vibration ended in less than a second. Jenna and Ethan saw the same pattern during in-and-out-of-bed drills: a turn or exit registered, but it did not send a pronounced ripple across the mattress. The trade-off appeared when changing positions. After removing the load, the foam took an average of 2.4 seconds to regain 90% of its height, so quick back-to-side turns required a little more effort than they did on a springier hybrid.

What we liked:

• Deep shoulder and hip relief without unstable sink under the midsection
• A genuinely cool first touch with good heat release after use
• Excellent motion control for partners with different schedules

Who it is best for:

• Couples who wake easily when a partner moves
• Back sleepers and side sleepers who want close contouring
• Hot sleepers who dislike the flat feel of an extra-firm mattress

Where it falls short:

• The foam does not rebound quickly enough for sleepers who turn often
• Its restrained bounce may feel dull if you prefer strong pushback
• The cooling package carries a price premium that value shoppers may not need

Luxury Firm is the best starting point for most back sleepers, side sleepers, and people who alternate between those positions. It provides noticeable cushioning but keeps the hips from settling too deeply. Plush Soft is better for lighter side sleepers who need more give at the shoulders and hips. Firm is the sensible choice for strict stomach sleepers and heavier sleepers who need stronger resistance under the midsection.

Choose the AS6 when motion isolation and pressure relief matter more than bounce. If you want a traditional, buoyant luxury feel, the Saatva Classic is easier to move across. If cooling remains the priority but you want faster response and a lower typical price, the Brooklyn Bedding Aurora Luxe Cooling is the closer match.

The AS6's slow, conforming surface is its clearest limitation. It absorbs motion beautifully, but quick turns require more effort than they do on a responsive hybrid. The price is also difficult to justify for a guest room or for sleepers who do not need advanced cooling materials. Plush Soft and Luxury Firm may allow too much hip sink for strict stomach sleepers, while Firm offers a better match. Finally, the 14-inch profile can make the bed sit high on a thick foundation and may require deep-pocket sheets.

The Saatva Classic is the better choice for shoppers who want a buoyant innerspring feel, a cushioned Euro top, and free in-room setup. Its dual-coil design makes changing positions easier than on the AS6, but it does not provide the same dense, quiet contouring. It also carries a lower typical price, though promotions vary.

The Brooklyn Bedding Aurora Luxe Cooling is the closest alternative for hot sleepers. Its GlacioTex cover, responsive copper foam, and zoned coils produce a quicker feel, and an optional pillow top adds cushioning. Choose it over the AS6 if you want easier movement or a lower price; choose the AS6 if motion control and a deeper foam hug matter more.

The TEMPUR-Adapt suits sleepers who want denser, more enveloping contouring and excellent motion absorption. The all-foam Medium feels more anchored than the AS6, while the Medium Hybrid adds easier movement and stronger edge support. The AS6 remains the better fit if cooling technology, multiple firmness choices, and a taller profile are priorities.

• Allow the mattress to expand fully and sleep on it for several nights before judging the firmness.
• Use a breathable protector so the cool-to-the-touch cover remains noticeable.
• Check pocket depth before buying sheets; the mattress is 14 inches tall before adding a protector or pad.
• On a slatted platform, confirm that the slats meet Amerisleep's width and spacing requirements.
• Rotate the mattress periodically to distribute wear across the comfort layers.
• Couples should repeat their normal getting-in, turning, and getting-out routine before the trial ends.
• When using an adjustable base, begin with modest angles while the foam breaks in.
