Amerisleep is a memory-foam-first brand whose AS lineup spans every firmness from AS1 (firm) through AS5 (plush), plus the newer AS6 Black flagship and the Organica latex hybrid. The whole range is built around the brand's plant-based Bio-Pur foam, which aims to keep contouring comfort without the heat retention of traditional memory foam. This guide draws on the brand's own model documentation and recent independent reviews from Sleep Foundation, Mattress Clarity, and NapLab to lay out who each model is best for and where Amerisleep fits among premium foam mattresses.

Who Amerisleep Is Best For
- Shoppers comparing multiple firmness options under one brand. The AS lineup covers firm to soft and adds hybrid configurations, so couples with different feel preferences can stay in-family.
- Hot sleepers who like a memory-foam feel. Bio-Pur is engineered as an open-cell foam to breathe better than closed-cell memory foam, and independent testing finds Amerisleep sleeps cooler than the all-foam category average.
- Combination sleepers and side sleepers. The medium AS3 is the most-recommended pick for mixed positions, while the softer AS5 targets pressure relief at the shoulders and hips.
Who Amerisleep Is Not Best For
- Sleepers who want strong bounce and a springy feel. Even the firmer AS1 and AS2 contour more than they push back; if you want innerspring lift, look elsewhere.
- Heavier sleepers above 230 lb who sleep close to the edge. The all-foam models offer modest edge support; the hybrid models or a different brand may be a better fit if perimeter sleeping is critical.
- Buyers who need the longest sleep trial in the market. Amerisleep's 100-night trial is industry-standard but shorter than the 180- and 365-night trials from some competitors.
The Amerisleep Lineup at a Glance
Models, firmness, best for:
- AS1 - firm. Best for stomach sleepers and back sleepers who want a flatter, supportive feel.
- AS2 - medium-firm. Often recommended for back sleepers needing lumbar support with some pressure relief.
- AS3 - medium. The flagship balanced pick for combination sleepers; the most-reviewed model in the line.
- AS4 - medium-soft. Side-sleeper-leaning with deeper contouring than the AS3.
- AS5 - soft. Plush option for lighter sleepers and side sleepers seeking maximum pressure relief.
- AS6 Black - premium hybrid. Newer flagship with reinforced edge support and stronger pressure relief; positioned as a Tempur-Pedic alternative.
- Organica - latex hybrid. Eco-leaning option using natural latex over coils, for shoppers avoiding synthetic foams.
Pricing varies by size and frequently shifts during seasonal promotions. Confirm current MSRP on the brand's site rather than relying on third-party snapshots.
Performance
Motion Isolation
All-foam models in the AS line are strong on motion isolation - a benefit memory foam is well known for. Couples who wake easily to a partner shifting positions tend to do well on the AS3 in particular.
Pressure Relief
The transition layer (Amerisleep calls it HIVE) uses targeted firmness zones to soften under shoulders and hips while staying firmer under the lower back. Side sleepers report the most benefit on the AS3 and AS5.
Temperature Control
Bio-Pur is open-celled, which lets airflow disperse heat better than dense memory foam. Independent testing finds Amerisleep sleeps cooler than the all-foam category average, though hot sleepers who run very warm may still prefer a hybrid.
Edge Support
Edge support is the all-foam line's softest spot - fine for sleeping, less ideal for sitting along the perimeter. The AS6 Black and Organica hybrids include reinforced coils for stronger edges.
Off-Gassing
Like most boxed foam mattresses, expect a mild new-foam smell on unboxing. It typically airs out within a couple of days in a ventilated room.
Construction
Heights run roughly 10 to 14 inches across the AS line. The standard stack is a breathable cover, a Bio-Pur comfort layer, an Affinity/HIVE transition layer with targeted zones, and a Bio-Core support base - see our guide to mattress materials for what each layer does. Hybrid models swap the support base for pocketed coils with reinforced edge perimeter.
Body Type and Sleep Position
Lightweight sleepers (under 130 lb): AS3 or AS5 - softer feels engage the comfort layer enough for pressure relief.
Average sleepers (130-230 lb): AS2 for back/stomach, AS3 for combination, AS4 or AS5 for side.
Heavier sleepers (over 230 lb): Consider the AS1, AS2, or a hybrid (AS6 Black, Organica) for stronger support and edge reinforcement.

How Amerisleep Compares
vs. Tempur-Pedic: Amerisleep offers a similar premium memory-foam feel at lower price points across the AS line, while the AS6 Black is positioned as the most direct Tempur alternative in the lineup.
vs. Saatva: Saatva leans innerspring/coil-on hybrid with a more traditional bouncy feel; Amerisleep is the better choice if you specifically want a memory-foam contouring feel.
vs. Casper / Leesa: Comparable bed-in-a-box positioning, but Amerisleep offers more granular firmness choices (AS1 through AS5) than most direct-to-consumer foam competitors.
Amerisleep mattress FAQ
Which Amerisleep mattress is most popular?
The AS3 is the most reviewed and most recommended model. Its medium feel works for the broadest range of body types and sleep positions, which is why third-party reviewers like Sleep Foundation and Mattress Clarity feature it as the flagship pick.
Is Amerisleep good for back pain?
Many reviewers and customers report meaningful relief on the medium AS3 and medium-firm AS2, which balance lumbar support with shoulder/hip contouring. People who need very firm support sometimes prefer the AS1 or a hybrid model.
How long do Amerisleep mattresses last?
Amerisleep covers material and workmanship defects under a 20-year warranty. Like most premium memory-foam mattresses, expect roughly 7 to 10 years of usable comfort life depending on use, body weight, and foundation support.
Does Amerisleep sleep hot?
Independent testing finds Amerisleep cooler than the all-foam category average, thanks to the open-cell Bio-Pur foam and breathable covers. Very hot sleepers may still prefer a hybrid model with coils for additional airflow.
Can you flip an Amerisleep mattress?
No. Amerisleep mattresses are one-sided, with the comfort layers built up from a support base. You can rotate them head-to-foot occasionally to even out wear, but you should not flip them.
