Puffy vs Amerisleep AS3: AS3 Wins for Hot Sleepers, Puffy for Value

Two all-foam mattresses, two very different pitches. The Puffy Mattress sells itself on cradling back support with body-adapting memory foam and a soft, breathable knit cover, at a headline price of $449 during the Columbus Day sale. The Amerisleep AS3 all-foam version sells itself on cooling: a Refresh cover that draws heat from your skin, plant-based Bio-Pur memory foam with an open-cell design, and HIVE technology for targeted support. Both are medium-feel foam beds aimed at the same broad audience, so the choice comes down to how much you care about temperature regulation versus how much you want to spend.

Which mattress should you choose between Puffy and Amerisleep AS3?

The Amerisleep AS3 all-foam version is the stronger pick for sleepers who run warm, because its cooling story is specific and measurable: a Refresh cover that pulls heat from the skin, an average surface temperature 7 degrees cooler over an eight-hour night, and open-cell Bio-Pur foam that lets more air escape than traditional memory foam. The Puffy Mattress is the pick for shoppers who want a medium-firm memory foam bed with cradling support, a 365-night trial and a lifetime warranty at a much lower entry price. Both ship free, and both are made in the USA.

How do the Puffy Mattress and Amerisleep AS3 compare side by side?

The table below lays out what each brand states about its own product. Where a figure is not given, the cell says so rather than guessing.

For a deeper look at each model, read the Puffy Mattress review and the Amerisleep AS3 review.

How do the two mattresses feel and support you?

Puffy describes its mattress as medium-firm with six layers of memory foam that cradle the body and support the back, adapting to the sleeper. The brand’s own review count sits at 14,072 with an average of 4.9 stars, which suggests a feel that a large number of buyers have settled into happily. Amerisleep positions the AS3 as a medium feel that balances comfort and support for all sleeping styles, with HIVE technology delivering targeted support and maximum airflow. The AS3 is described as the brand’s most popular mattress, endorsed by the American Chiropractic Association and evaluated by board-certified doctors of chiropractic.

Neither brand publishes a firmness number on these pages, so a direct numerical comparison is not possible. What is clear is that Puffy leans into cradling and contouring, while Amerisleep leans into responsive support that snaps back to shape in seconds so the sleeper does not sink uncomfortably.

Which mattress sleeps cooler?

The Amerisleep AS3 wins this axis outright. Its Refresh cover is made from a fiber with high energy transfer that draws heat from the skin, and Amerisleep states the sleeping surface stays on average 7 degrees cooler over an eight-hour night. The plant-based Bio-Pur foam has an open-cell design that allows more air to circulate than traditional foam, wicking away warm air. Puffy counters that its mattress is cool to the touch with a soft, breathable knit cover, which is a real claim but a lighter one: no temperature figure is attached to it.

If night sweats are your main complaint, the AS3 is built specifically for that problem. If you simply want a cover that does not trap heat, Puffy’s breathable knit does the job.

What are the materials in each mattress?

Puffy builds its mattress from six layers of memory foam under a soft, breathable knit cover. The brand emphasizes body-adapting foam that cradles the back. Amerisleep uses plant-based Bio-Pur memory foam, which the brand says contains a fraction of the petrochemicals used in other memory foams, is less likely to off-gas, and is completely free of harmful substances. The AS3 is explicitly fiberglass-free, eco-friendly and non-toxic. HIVE technology provides targeted support across the surface.

Both mattresses are made in the USA. Puffy notes its product is assembled in the USA; Amerisleep notes the AS3 is made in the USA of US materials.

What do trial, warranty and shipping look like?

Puffy offers a 365-night sleep trial, a lifetime warranty, and free shipping with free returns, with mattresses shipping in 1 to 2 days. Amerisleep offers a 100-night trial, a 20-year warranty, and free shipping and returns with no-contact fast delivery. Puffy’s trial is longer by a wide margin and its warranty is lifetime rather than 20 years; Amerisleep’s trial is about three months but still gives time to decide.

Both brands make returns easy and free, so the risk profile is low either way. The difference is in the length of time you get to live with the decision.

Who should buy the Puffy Mattress?

The Puffy Mattress suits the shopper who wants a medium-firm memory foam bed with cradling back support, a breathable cover, and the longest possible runway to change their mind. Its 365-night trial and lifetime warranty match the Saatva Classic’s terms, and the $449 sale price makes it the clear budget pick, though prices change with promotions. If you sleep warm but not extremely so, the cool-to-the-touch knit cover may be enough. If you want a mattress that adapts to your body and relieves pressure at the hips and shoulders, Puffy’s cradling foam is built for that. It is also the sensible first mattress for a guest room or a first apartment, where the lower outlay matters. Shoppers who want a longer trial than 100 nights should lean this way. And if you simply prefer the feel of classic memory foam over a more responsive plant-based formula, Puffy is the more traditional choice of the two.

Who should buy the Amerisleep AS3?

The Amerisleep AS3 all-foam version suits sleepers who overheat at night and want a mattress engineered around that single problem. The Refresh cover, the open-cell Bio-Pur foam and the stated 7-degree average cooling over eight hours make it the most temperature-focused product here. It also suits sleepers who want balanced support for any position, since Amerisleep describes the AS3 as comfortable for all sleeping styles, with HIVE technology delivering targeted support where it is needed. The 12-inch profile gives it a substantial presence on the bed. Buyers who care about material transparency will appreciate that it is fiberglass-free, non-toxic and made in the USA. It is endorsed by the American Chiropractic Association and was voted Newsweek Readers’ Choice Best Mattress of 2026, which matters if third-party recognition reassures you. The AS3 also suits sleepers who want foam that responds quickly rather than swallowing them, because Bio-Pur snaps back to shape in seconds. If you have read about traditional memory foam holding heat and staying slow to recover, this is the version of memory foam designed to fix exactly that. Finally, it suits shoppers who are comfortable with a 100-night trial and a 20-year warranty in exchange for a more specialized cooling build.

What is the value proposition of each mattress?

Puffy’s headline price during the Columbus Day sale is $449, with a stated total value of $1,849 and a free bundle of two signature pillows and a signature sleep mask. Amerisleep lists the AS3 all-foam queen at $1,149 against a list price of $1,749. Prices change with promotions, so check the current price before buying. On trial length and warranty, Puffy offers more nights and longer coverage. On cooling technology and third-party endorsements, Amerisleep offers more. Neither mattress is a bad value; they are priced for different budgets and different priorities.

Who should NOT buy which mattress?

Skip the Puffy Mattress if night sweats are your primary complaint, because its cooling claim is limited to a cool-to-the-touch cover with no temperature figure behind it. Skip the Amerisleep AS3 if you want more than 100 nights to decide, or if a lifetime warranty matters to you, because its trial is 100 nights and its warranty is 20 years. Also skip the AS3 if you are shopping on a tight budget, since its queen price sits well above Puffy’s entry price. Neither mattress is a hybrid: if you want coils, look at the AS3 Hybrid as a separate model, or consider the Saatva Classic.

What is a strong alternative to both?

The Saatva Classic is an innerspring mattress rather than an all-foam one, which makes it a genuinely different option for sleepers who do not want foam at all. It comes in three comfort levels: Plush Soft at 3 out of 10 for side and lighter sleepers, Luxury Firm at 5 to 7 out of 10 as the most popular choice for all positions, and Firm at 8 out of 10 for stomach and back sleepers. It has a 3-inch Euro pillow top, a dual-coil design with over 1,000 recycled carbon steel coils in full size and up, and patented Lumbar Zone technology for spinal alignment. It is endorsed by the American Chiropractic Association, CertiPUR-US certified and GREENGUARD Gold certified. Delivery includes free white-glove setup and removal of your old mattress, the trial runs 365 nights, and the warranty is lifetime. If neither foam mattress here feels like the right answer, the Saatva Classic is the alternative worth a look.

World Sleep Almanac score: 8.4/10 for the Saatva Classic. Criteria: price at equal size, trial and returns, warranty, materials and construction, and public customer reviews. The score is editorial and reflects how the product performs against these five criteria, not a laboratory test.

Frequently asked questions

Is the Puffy Mattress or the Amerisleep AS3 better for side sleepers?

Both are described in medium-feel territory, which generally suits side sleepers. Puffy emphasizes cradling memory foam that adapts to the body, while Amerisleep describes the AS3 as balanced comfort and support for all sleeping styles. Neither brand publishes a firmness number on these pages, so the honest answer is that both should work and your own preference for contouring versus responsiveness will decide it.

Which mattress has a longer trial period?

Puffy offers 365 nights. Amerisleep offers 100 nights. That is the single biggest policy difference between the two products.

Does the Amerisleep AS3 contain fiberglass?

No. Amerisleep states the AS3 is fiberglass-free, eco-friendly and non-toxic.

Can I get the Amerisleep AS3 with coils?

Yes, but that is a separate product. The AS3 Hybrid combines foam and wrapped coils and is not the version compared on this page.

Which mattress is better for hot sleepers?

The Amerisleep AS3. Its Refresh cover and open-cell Bio-Pur foam are built to move heat away from the body, with an average surface temperature 7 degrees cooler over an eight-hour night. Puffy’s cover is cool to the touch and breathable, but no temperature figure is attached to it.

Verdict: the Amerisleep AS3 all-foam version wins this face-to-face for hot sleepers and anyone who values targeted, responsive support, while the Puffy Mattress wins for shoppers who want a longer trial, a lifetime warranty and a lower entry price. Pick the AS3 if temperature is your problem. Pick Puffy if policy length and budget are yours. If neither foam bed convinces you, the Saatva Classic offers an innerspring alternative with the same 365-night trial and lifetime warranty as Puffy, plus free white-glove delivery.
