Amerisleep gives you a six-model lineup tuned to sleep position; Puffy keeps it simple with three plush options and a lifetime warranty. Here is who each one is built for.
Amerisleep and Puffy both make their case as premium online memory-foam brands, but they take very different approaches. Amerisleep sells a six-model lineup (AS1 through AS6 plus the latex Organica) where each number maps to a firmness and a sleep style. Puffy keeps the catalog tight: three names - Cloud, Lux, and Royal - each available in foam or hybrid. The right pick comes down to how dialed-in you want your firmness, how hot you sleep, and what you expect from a warranty.
Pick Amerisleep if you want a firmness tuned to your exact sleep position, faster-responding plant-based foam, and the option to step up to a hybrid for cooling and edge support. Pick Puffy if you want a softer, plusher feel right out of the box, the longest warranty in the industry (lifetime), and a simpler lineup that's easier to choose from.
Each Puffy model is also offered as a hybrid (Cloud Hybrid, Lux Hybrid, Royal Hybrid) for sleepers who want springs underneath the foam.
Both brands stack a cooling foam top, a transition layer, and a high-density support core. The differences are in the foam chemistry.
Amerisleep gives you the wider firmness range. With six numbered models you can find a true firm (AS1, ~8/10) all the way to a true plush (AS5, ~3/10). Puffy stays in the medium-firm to medium-soft band - Cloud is the firmest at roughly 6.5/10, Royal the softest at about 5.5/10. If you sleep mostly on your stomach or weigh over 230 lb, Amerisleep has options Puffy doesn't.
On feel: Puffy delivers the classic memory-foam hug. Slow, sinking, body-cradling. Amerisleep's Bio-Pur foam is buoyant - you feel cradled but you don't feel stuck. Combo sleepers and anyone who hates the "quicksand" feel of old memory foam will prefer Amerisleep.
Both brands market themselves as cool-sleeping memory foam, but the mechanisms differ. Amerisleep relies on the open-cell Bio-Pur structure plus a HIVE transition layer with airflow channels. Puffy relies on gel infusion in the top layer. In practice, Amerisleep tends to sleep cooler in the all-foam matchup because plant-based foams shed heat faster than gel-foam alone. Hot sleepers should still pick a hybrid from either brand - adding coils makes a bigger difference than any foam tweak.
Puffy wins on motion isolation: gel-infused memory foam absorbs movement better than plant-based foam. If your partner tosses, Puffy will let you sleep through more of it. Amerisleep wins on edge support, especially on the AS5H and AS6 Black, which use reinforced perimeter coils. Puffy's all-foam models have noticeably softer edges.
Both brands run constant promotions, so check the live price. As a baseline:
Puffy is generally the friendlier MSRP at the entry tier; Amerisleep climbs higher at the top end (the AS6 Black is a true luxury hybrid).

Amerisleep AS2 is the stronger pick for back pain. Its medium-firm Bio-Pur foam keeps the spine aligned without sinking, and the HIVE transition layer adds targeted lumbar support. Puffy's softer feel can let heavier hips drop, which aggravates lower-back pain over time.
In the all-foam matchup, Amerisleep is cooler. Its plant-based Bio-Pur foam has an open-cell structure that releases body heat faster than Puffy's gel-infused memory foam. If you run very hot, pick a hybrid from either brand - coils ventilate better than any foam tweak.
Yes for sleepers who plan to keep the same mattress 12+ years. Puffy covers manufacturing defects and excessive sagging (over 1.5 inches) for as long as you own the bed. Amerisleep's 20-year warranty is still strong, but it caps protection where Puffy keeps going.
Both are primarily online. Puffy ships in a box with a 101-night home trial. Amerisleep ships in a box with a 100-night trial. Returns are free both ways. A handful of Amerisleep mattresses appear in select brick-and-mortar showrooms, but coverage is limited.
For most sleepers, Amerisleep AS5 Hybrid or AS6 Black edge out Puffy Lux Hybrid on edge support and cooling. Puffy Lux Hybrid wins on motion isolation. If you share the bed and your partner tosses, Puffy. If you sleep hot or weigh over 230 lb, Amerisleep.
Puffy Cloud is the cheaper entry point and includes the lifetime warranty, so on raw dollars it wins value. But Amerisleep's tighter firmness fit means fewer sleepers send it back - a $200 saving means nothing if the bed is wrong for your body.
