PlushBeds Botanical Bliss vs Amerisleep AS3: Which Foam Mattress Wins?

Two foam mattresses, two very different material stories. Skip the PlushBeds Botanical Bliss if you specifically want memory foam contouring rather than latex; consider the Amerisleep AS3 instead. The PlushBeds Botanical Bliss is built from organic latex with GOTS and GOLS certification and a lifetime warranty, while the Amerisleep AS3 in its all-foam version uses plant-based Bio-Pur memory foam with a Refresh cooling cover and a 20-year warranty. Both are sold as medium-feel, all-position mattresses, and both are aimed at sleepers who want pressure relief without coils. The question this page answers is simple: which of the two fits you better, and when is a third option the smarter buy.

Which mattress should you choose between the Botanical Bliss and the AS3?

The short answer: pick the PlushBeds Botanical Bliss if certified organic latex and a lifetime warranty matter to you, and pick the Amerisleep AS3 all-foam if you want a plant-based memory foam feel with a cooling cover at a published queen price of $1,149. The Botanical Bliss offers three heights, two firmness options and split configurations, while the AS3 is offered as a single 12-inch medium profile. Neither mattress is sold by Saatva, so the Saatva Classic appears on this page only as an alternative for readers who want a coil-based build instead.

Who is each mattress for?

The Botanical Bliss suits the sleeper who reads labels. Its page leads with GOTS and GOLS certification, a lifetime warranty and a 365-night return policy, and it offers a 365-night comfort exchange. It also gives you more configuration choices: heights of 9, 10 and 12 inches, Medium and Med-Firm feels, and split sizes including Split King, Split Queen and Split Cal King, plus a dual firmness option. That range makes it a natural fit for couples who want different feels on each side, or for anyone who wants to match mattress height to an existing bed frame.

The AS3 all-foam suits the sleeper who wants a single, clearly defined option. Amerisleep presents it as a medium feel in a 12-inch profile, balanced for all sleeping styles, with Bio-Pur memory foam and HIVE technology for targeted support. It is fiberglass-free and made in the USA. The page also notes a 100-night trial, free shipping and returns, and a 20-year warranty, which is a shorter trial and a shorter warranty term than the Botanical Bliss offers.

How do the two mattresses compare on paper?

The table below lines up what each official product page states. A price appears only where the source gives one with its size.

How does each mattress feel and support you?

The Botanical Bliss gives you a choice, which is the core of its support story. You select Medium or Med-Firm, then select a height, and for split sizes you can pair Medium with Med-Firm in a dual firmness configuration. Latex as a material is responsive rather than contouring, and the page positions the mattress around certified organic materials rather than around a memory foam hug. If you already know you dislike sinking into foam, that distinction matters more than any single spec.

The AS3 all-foam takes the opposite approach: one feel, clearly described. Amerisleep calls it a medium feel with balanced comfort and support for all sleeping styles, built on Bio-Pur memory foam with HIVE technology for targeted support. Bio-Pur is described as open-cell, more breathable than traditional memory foam, and quick to return to shape, so the sleeper does not sink in and stay there. If you want a memory foam feel and do not want to choose between firmness levels, the AS3 removes the decision for you.

Which materials are actually inside each mattress?

The Botanical Bliss is an organic latex mattress, and its certification story is the reason many shoppers shortlist it. GOTS and GOLS certification covers the organic latex construction, and the product page pairs that with a lifetime warranty and a 365-night return policy. Latex is a single material family throughout the build, which keeps the specification simple: you are buying certified organic latex in the height and firmness you choose.

The AS3 all-foam is a layered foam mattress. Its comfort layer is Bio-Pur, a plant-based memory foam that Amerisleep describes as containing a fraction of the petrochemicals used in other memory foams, with less likelihood of off-gassing and no harmful substances. Support comes from HIVE technology, which the brand describes as delivering airflow and targeted support. The mattress is fiberglass-free, non-toxic and made in the USA. The AS3 Hybrid is a separate product with coils and is not part of this comparison.

Which mattress is better for hot sleepers?

Only one of the two pages makes a specific cooling claim. Amerisleep states that the Refresh Cover draws heat from the skin for a cool-to-the-touch feel and that the sleeping surface stays on average 7 degrees cooler over an eight-hour night, with Bio-Pur’s open-cell design allowing more air to circulate than traditional foam. If a stated cooling number matters to your decision, the AS3 is the only one of the pair that provides one.

What do trial, warranty and delivery look like?

The Botanical Bliss carries a 365-night return policy and a 365-night comfort exchange, alongside its lifetime warranty. Shipping is free within the US, excluding Alaska and Hawaii, and white glove delivery is available with a minimum purchase. Mattresses ship within 4 to 7 business days according to the product page.

The AS3 carries a 100-night sleep trial, free shipping and returns, and a 20-year warranty. On trial length and warranty term, the Botanical Bliss is the longer commitment on both counts, while the AS3 keeps the entry point simpler. Neither page publishes a white glove delivery option for the AS3, so readers who want in-room setup should confirm that directly with the brand before ordering.

Which mattress offers better value?

Value here is a question of what you are buying, not only what you are paying. The Amerisleep AS3 all-foam is published at Queen: $1,149 against a list price of $1,749, and prices change with promotions. What the two prices would need to be weighed against differs: certified organic latex with a lifetime warranty on one side, plant-based memory foam with a 20-year warranty and a stated cooling cover on the other. Readers who want the full price list for the Botanical Bliss across sizes, heights and firmness levels should read our PlushBeds Botanical Bliss review, and the AS3 in detail in our Amerisleep AS3 review.

Who should NOT buy each mattress?

Skip the Botanical Bliss if you want a single simple option rather than a matrix of size, height and firmness choices, or if you specifically want a memory foam contour rather than a latex feel. Its configuration range is an advantage only if you intend to use it.

Skip the AS3 all-foam if you want certified organic materials, a trial longer than 100 nights, a warranty longer than 20 years, or a split firmness setup for two sleepers. It also is not the right choice if you want coils, since the hybrid version is a different product entirely.

So which one wins?

For readers who weight organic certification, configuration choice and the longest trial and warranty terms, the PlushBeds Botanical Bliss is the better buy of these two. For readers who want a straightforward medium memory foam mattress with a published queen price and a stated cooling cover, the Amerisleep AS3 all-foam is the easier recommendation. The choice follows your material preference more than any single number: latex with certification, or plant-based memory foam with a cooling story.

World Sleep Almanac score: 7.9/10. The score is an editorial rating based on these criteria: price at equal size, trial and return terms, warranty length, materials and construction, and publicly stated certifications. It is not a laboratory test result.

Verdict: the Botanical Bliss wins for the organic-latex shopper who will use its firmness and height options, and the AS3 wins for the shopper who wants one clear medium foam option with a published queen price. If neither foam build appeals, the Saatva Classic offers a coil-based alternative with three comfort levels, a 365-night home trial and a lifetime warranty.

Frequently asked questions

Is the Botanical Bliss a memory foam mattress?

No. The PlushBeds Botanical Bliss is built from organic latex and carries GOTS and GOLS certification. It does not use memory foam, so the feel is responsive rather than contouring. Sleepers who want a memory foam hug should look at the AS3 instead, or at a coil option such as the Saatva Classic.

Does the AS3 all-foam come in different firmness levels?

No. The all-foam AS3 is offered as a single medium feel in a 12-inch profile, described as balanced for all sleeping styles. The Botanical Bliss, by contrast, offers Medium and Med-Firm, plus a dual firmness option on split sizes. If choosing a firmness level matters to you, only one of these two gives you that choice.

Which mattress has the longer trial period?

The Botanical Bliss, with a 365-night return policy and a 365-night comfort exchange. The AS3 all-foam carries a 100-night sleep trial. The same pattern holds for warranty: lifetime on the Botanical Bliss, 20 years on the AS3.

Can I get the AS3 with coils instead of foam?

Amerisleep sells an AS3 Hybrid as a separate product with foam and coils. This comparison covers the all-foam version only, and the hybrid is not part of the table or the verdict above.

Which mattress should side sleepers consider?

Both are presented as medium-feel mattresses suitable for all sleeping styles, so either can work for side sleeping. The Botanical Bliss adds a Med-Firm option and multiple heights if you want to fine-tune the feel, while the AS3 keeps a single medium configuration. Your own weight and pressure points will decide more than the label on the page.
