An editor's guide to the Amerisleep mattress lineup - AS1 through AS6 Black plus the Organica hybrid - covering firmness feel, cooling, pressure relief, and who each model best fits.
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.

Models, firmness, best for:
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.
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.
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.
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 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.
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.
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.
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.

Confirm specifics on the manufacturer's policy page before ordering - terms occasionally change.
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.
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.
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.
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.
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.
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.
