Amerisleep AS3 vs Brooklyn Signature Hybrid: Which Should You Buy?

These prices and specifications are for the all-foam AS3 and the standard Signature Hybrid without the optional Cloud Pillow Top. The AS3 Hybrid and pillow-top configuration use different materials and have different prices.

How do these mattresses compare at a glance?

Both brands sell directly online, offer free shipping, and give you a home trial. The biggest practical distinction is the feel and support system: the AS3 keeps the recipe all foam with a medium label, while Brooklyn puts pocketed coils under foam and lets you select soft, medium, or firm. Brooklyn also lists a longer trial and limited lifetime warranty. Amerisleep’s edge is a singular medium model with its Bio-Pur and HIVE features, not a longer warranty or a cheaper ticket.

Both policies cover qualifying defects, not normal comfort preferences. Amerisleep’s 20-year warranty covers a visible indentation greater than 1.5 inches toward the mattress center, but not corners or edges; years 1–10 are full replacement, and years 11–20 are prorated at 50% of the original price plus shipping, cover, and labor. Its non-brand slats must be no more than 2.75 inches apart; a box spring needs a full ¾-inch moisture-resistant plywood sheet. Brooklyn’s post-February 1, 2025 limited lifetime warranty also covers center indentations over 1.5 inches; slats wider than 5 inches void coverage. Years 1–10 are non-prorated; afterward, replacement costs are prorated: 50% of then-current retail price in years 11–15, 60% in years 16–20, and 75% from year 21. Both warranties require proper support; check each full policy before purchase.

What does each mattress feel like?

The AS3 is a 12-inch all-foam mattress that Amerisleep labels medium. Its Bio-Pur comfort foam is designed to contour, and the HIVE layer divides support into zones. You get one defined feel rather than a choice of firmness. Foam has no coil unit underneath, so the bed’s response comes from its foam layers: if you like a closer, more contouring surface, that is the direction to consider.

The Signature Hybrid pairs foam with encased coils. Brooklyn’s page gives you three firmness selections: soft, medium, and firm. The core includes 8-inch Ascension X coils, with the company describing them as encased for contouring, motion isolation, and edge support. That construction makes it the more adaptable pick on paper if the sleepers sharing the bed disagree about firmness or if you want a more springy response than an all-foam mattress offers.

There is no universal “best” firmness for a sleep position. Side sleepers often look for room at the shoulder and hip; back and stomach sleepers may prefer a surface that feels more supportive under the midsection. Body weight, pillow height, and personal preference change the result. Brooklyn’s three firmness options make it easier to choose a direction, but do not guarantee a particular sensation for every sleeper. Amerisleep’s medium feel is a straightforward starting point for combination sleepers who do not want to choose between firmness variants.

Side sleeping

If you sleep on your side and like a cushioned surface, compare the AS3’s medium foam feel with Brooklyn’s soft or medium version. The Signature gives you an extra firmness option; the AS3 gives you one consistent model. Neither label can tell you exactly how much your shoulder will sink, so use the trial terms as a backup rather than treating a firmness name as a comfort guarantee.

Back or stomach sleeping

Back sleepers who want foam contouring can begin with the AS3. If you prefer a firmer feel, or sleep mostly on your stomach and do not want a medium foam surface, Brooklyn’s firm option is the clearer alternative. Mattress fit depends on your body and sleeping position; do not choose based on a brand’s broad “for all sleep styles” language alone.

Combination sleeping

Brooklyn’s coil support and choice of firmness may suit you if you change positions often and prefer a more buoyant feel. Amerisleep describes Bio-Pur as more responsive than traditional memory foam; the company positions the AS3 for multiple sleep styles. If you dislike the close hug of memory foam, try to test a foam feel before deciding. If you like contouring and want medium, the AS3 is the cleaner match.

Which mattress has the better cooling and edge support?

Both companies advertise cooling features, not a guaranteed sleep temperature. Amerisleep pairs its Refresh cover with open-cell Bio-Pur foam and describes the design as cooling. Brooklyn lists a GlacioTex cooling cover and cooling features in its foam layers; it also offers an optional Cloud Pillow Top. Room temperature, sheets, bedding, and personal heat sensitivity affect how cool a mattress feels.

Brooklyn Bedding says its encased coils add edge support and stability. The AS3 uses an all-foam support system with HIVE zoning. If you use the full mattress width or sit on the edge, Brooklyn's coil design is the feature to compare; actual support depends on the setup and sleeper.

Want Brooklyn’s upgraded pillow top? Add it only if you want that extra layer and are comfortable with its added price. The pillow-top version is taller and changes the surface feel; it is not the same product configuration as the standard Signature Hybrid compared here.

How much does each size cost?

Listed prices: Amerisleep showed the AS3 Queen at $1,249, reduced from $1,749 with a $500 offer. Its size listings showed the prices below. Brooklyn listed the standard prices below and advertised a 25% sitewide promotion code. Sale offers and checkout totals can change; compare the same size and selected firmness before you order.

Brooklyn also lists nonstandard sizes, and Amerisleep offers Split King; those configurations are not directly comparable in this table. At Queen, the AS3’s displayed sale price is below Brooklyn’s regular listed price, while Brooklyn’s advertised discount may change the checkout comparison. Include the pillow-top upgrade only if you want that configuration.

Which trial, return policy, and warranty make more sense?

Brooklyn offers 120 nights, with a 30-night minimum and a $99 return fee. Amerisleep offers 100 nights, a 30-night minimum, and free returns. Compare trial time and return cost separately.

Warranty length favors Brooklyn by headline duration: its Signature Hybrid page advertises a limited lifetime warranty, while Amerisleep offers a 20-year warranty. “Limited lifetime” does not mean every issue is covered forever, and a longer label does not establish that a mattress lasts longer. Compare the actual written coverage, including sagging thresholds, foundations, stains, and whether transportation or replacement costs apply. The practical choice is Brooklyn for more trial nights and a longer headline warranty; Amerisleep for a 100-night trial and a defined 20-year term.

Both brands advertise free shipping. Amerisleep estimates delivery in 3–7 business days; Brooklyn estimates 5–8 business days and ships the mattress compressed in a box. Timing can vary by address and availability. Follow the setup instructions and allow the mattress to expand as directed.

What does a return actually cost?

Who should buy the Amerisleep AS3?

Choose the AS3 if:

• You want an all-foam mattress, not a hybrid with coils.
• You are looking for a defined medium feel rather than multiple firmness choices.
• You value a design that combines Bio-Pur memory foam with HIVE zoned support.
• You want to compare the current direct-sale price and 100-night trial, then decide at home.

Look elsewhere if: you strongly prefer an innerspring-like response, want soft or firm as a selectable option, need a longer trial, or want the longer warranty term Brooklyn advertises. The AS3 is not the automatic fit for someone who dislikes foam contouring.

Who should NOT buy the AS3?

Skip the AS3 if you want a coil feel, need a selectable firm or soft version, or would rather have 120 trial nights than 100. If the $99 Brooklyn return fee matters less to you than getting a spring-supported mattress, compare Brooklyn’s firmness options instead.

Who should buy the Brooklyn Signature Hybrid?

Choose the Signature Hybrid if:

• You specifically want a hybrid mattress with an encased-coil support core.
• You want to select soft, medium, or firm instead of buying one medium model.
• You want Brooklyn’s longer 120-night trial and limited lifetime warranty terms.
• You are comparing the live sale price and do not mind checking the final cart and any code.

Look elsewhere if: you prefer an all-foam bed with no coil unit, or you want the pillow-top configuration’s feel without adding its extra cost. The Signature is the more flexible product on firmness; the AS3 is simpler if medium foam is exactly what you want.

Who should NOT buy the Signature Hybrid?

Skip Brooklyn if you want one all-foam medium design, object to paying a $99 return fee, or do not want to choose among soft, medium, and firm. If you already know you want medium foam with zoned support, the AS3 is the more direct match.

Also considered

• Amerisleep AS2: another Amerisleep model to compare if you want to look beyond the AS3.
• Amerisleep AS5: a second alternative in Amerisleep’s lineup if you are considering a different model rather than the AS3.
• Brooklyn Bedding Signature Hybrid with Cloud Pillow Top: consider this configuration if you specifically want the added pillow-top layer; its height and price differ from the standard model here.

Our verdict: Amerisleep AS3 wins for the buyer who wants medium foam

The AS3 wins for shoppers who want medium all-foam construction with Bio-Pur and HIVE zoning, backed by a 100-night trial and a 20-year warranty. Choose Brooklyn instead if you want coils, a soft or firm option, 20 extra trial nights, or its limited lifetime warranty. Match the construction and feel to your preference before comparing live checkout prices.

Frequently asked questions

Is the Amerisleep AS3 better than the Brooklyn Signature Hybrid?

The AS3 is our overall pick for a shopper seeking a medium all-foam mattress with Bio-Pur and HIVE. The Signature Hybrid is a stronger fit if you want coils, three firmness choices, a 120-night trial, or Brooklyn’s limited lifetime warranty. “Better” depends on which of those differences matters to you.

Which mattress is softer?

The AS3 is labeled medium by Amerisleep. Brooklyn lets you select soft, medium, or firm. The soft Signature option is the softer labeled choice in this comparison, but the actual feel depends on body weight, shape, and preference.

Does the Brooklyn Signature Hybrid sleep cooler than the AS3?

Amerisleep advertises a Refresh cover and Bio-Pur foam; Brooklyn advertises a GlacioTex cover and cooling-related foam features. Neither brand promises a specific sleep temperature, so choose based on the construction and feel you prefer.

Which one has better edge support?

Brooklyn Bedding says its encased coils add edge support; the AS3 uses foam throughout. If edge sitting or sleeping near the side matters to you, the hybrid's coil perimeter is the relevant distinction. Try the model or use the applicable home trial to decide how it feels in your setup.

Is the Brooklyn Signature Hybrid a better deal?

Brooklyn listed the Queen at $1,465 and advertised 25% off sitewide. Amerisleep displayed the Queen at $1,249 with a $500 offer. Promotions change, so compare the checkout total for the same size and configuration rather than relying on a sale banner.

How long is the trial for each mattress?

Amerisleep advertises a 100-night trial. Brooklyn Bedding advertises a 120-night trial and requires at least 30 nights before a return; its policy charges a $99 return fee. Amerisleep advertises free returns after the first 30 nights.

Does Brooklyn’s lifetime warranty mean the mattress lasts forever?

No. Brooklyn calls its warranty limited lifetime coverage, which is governed by written limits and exclusions. A warranty is not a lifespan promise; read the exact terms and compare them with Amerisleep’s 20-year warranty document.

Is the AS3 Hybrid the same mattress as the AS3?

No. Amerisleep sells an all-foam AS3 and a separate AS3 Hybrid with coils. This comparison and the listed AS3 prices cover the standard all-foam version unless the text specifically says otherwise.
