Amerisleep AS3 vs Brooklyn Bedding: Which Foam or Coil Wins

Two mid-market mattresses, two different ideas of comfort. The Amerisleep AS3 in its all-foam version bets on plant-based Bio-Pur memory foam, a Refresh cooling cover and a medium feel in a 12-inch profile. The Brooklyn Bedding Signature Hybrid answers with foam over an encased coil system, three firmness choices and a cool-to-the-touch cover at a factory-direct price. One is an all-foam bed with a single firmness, the other a coil mattress you can order soft, medium or firm. This face-to-face walks through feel, materials, temperature, trial terms and value so you can pick the one that matches how you sleep.

Which mattress should you choose between the AS3 and the Signature Hybrid?

The short answer: pick the Amerisleep AS3 all-foam if you want a single medium feel, contouring memory foam and a cover engineered to sleep cool, and you are comfortable with one firmness option. Pick the Brooklyn Bedding Signature Hybrid if you want coils under you, a choice of soft, medium or firm, and a trial that runs a full year. The AS3 gives you one carefully tuned configuration; the Signature lets you match firmness to your sleep position before you buy. Both ship free, both are fiberglass-free or certified on the foam side, and both come from established online brands.

Who is each mattress for?

Choose the Amerisleep AS3 all-foam if you sleep on your side, back or a mix of both and want balanced comfort for all sleeping styles in a medium feel. Its Bio-Pur memory foam is open-cell and plant-based, designed to snap back to shape in seconds so you do not sink in, and the HIVE technology is built for targeted support and airflow. The Refresh cover draws heat from the skin, and Amerisleep states the surface stays on average 7 degrees cooler over an eight-hour night. The AS3 is fiberglass-free and made in the USA. It suits sleepers who prefer foam contouring over the push of coils, and who want a mattress evaluated by board-certified doctors of chiropractic and endorsed by the American Chiropractic Association.

Choose the Brooklyn Bedding Signature Hybrid if you want a hybrid build: pressure-relieving quilt foam over an 8-inch Ascension X coil system with 3.5 inches of comfort foam, for a total height of 13.25 inches without the pillowtop and 14 inches with it. It comes in soft, medium and firm, so side sleepers can take soft, combination sleepers medium, and back or stomach sleepers firm. The encased coils and sturdy base are built for motion isolation and edge support across the whole surface. It suits value seekers who want factory-direct pricing, shoppers who need a specific firmness, and anyone who can add the optional GlacioTex cooling cover or Cloud Cooling Pillow Top.

How do the two mattresses compare on paper?

Both prices above are the list prices shown for the queen size on each brand’s own page. Promotions change what you actually pay at checkout, so treat them as the reference figures rather than a guarantee.

Which feels better: foam contouring or coils under you?

The AS3 offers one feel and does it thoroughly. Medium, 12 inches tall, with plant-based Bio-Pur on top that contours to the body and returns to shape quickly, plus HIVE technology for zoned support. Amerisleep describes it as balanced comfort and support perfect for all sleeping styles, which makes it a safe single choice for couples who cannot agree, as long as medium suits both of you. There is no firmness choice to make, which removes a decision and also removes an escape route if medium turns out wrong for your build.

The Signature Hybrid gives you the decision up front. Soft for side sleepers, medium for combination sleepers, firm for back and stomach sleepers, plus an optional pillowtop if you want more cushion. That is a meaningful advantage for anyone who already knows their position: a firm Signature for stomach sleeping is a different mattress from a soft Signature for side sleeping, while the AS3 is medium for everyone. The coil layer also gives a more responsive, lifted feel than foam alone, which combination sleepers tend to notice when they roll over.

Which one sleeps cooler?

Both brands put cooling at the center of the pitch, but they attack it from different angles. The AS3 uses a Refresh cover made from a fiber with high energy transfer that draws heat from the skin for a cool-to-the-touch feel, and Amerisleep states the surface stays on average 7 degrees cooler over an eight-hour night. Underneath, the open-cell Bio-Pur lets more air circulate than traditional foam, which is the standard argument against memory foam sleeping hot. Far infrared exposure from the cover is also cited by Amerisleep, referencing the Journal of Photonics and Lasers in Medicine.

The Signature Hybrid layers its own solutions: a ThermoPhase foam with phase change material that absorbs and releases heat, copper-infused foam for heat dispersion, a moisture-wicking quilt foam, and the GlacioTex cooling cover sewn into the top fabric. The pillowtop upgrade pairs GlacioTex with a dual layer of pillowtop foam. If cooling is your main worry, the AS3 makes a single quantified claim you can weigh, while the Signature gives you a menu of cooling features that scale with the option you order.

What do trial, warranty and shipping look like?

The gap here is wide and easy to state. Amerisleep backs the AS3 with a 100-night sleep trial, free shipping and returns, and a 20-year warranty, with the mattress made in the USA. Brooklyn Bedding gives the Signature Hybrid a 365-night trial, free shipping and a Limited Lifetime Warranty, with mattresses roll-packed and delivered to the door. HSA and FSA payment is available for qualified customers on the Brooklyn side.

A year-long trial versus a 100-night trial is the single biggest policy difference in this comparison. If you want a full seasonal cycle to decide, including a hot summer and a cold winter, the Signature covers that. If 100 nights is enough for you to know, the AS3 terms are straightforward and include easy and free returns.

Which offers better value?

Value here is about what you get for the money, not a discount percentage. The AS3 queen lists at $1,149 and the Signature Hybrid queen at $1,465, so the foam mattress is the cheaper of the two at this size while offering a cooling cover and a 20-year warranty as standard. The Signature asks more for a queen, and in return you get coils, a choice of three firmnesses, a 365-night trial and a lifetime warranty, with the pillowtop and GlacioTex cover as paid upgrades. Neither brand’s price should be read as final: both run promotions, and the number to compare is the one you see at checkout on the day you order.

Brooklyn Bedding also publishes its full size ladder, from twin at $959 up to king and Cal King at $1,865, which makes budgeting across sizes simple. Amerisleep’s page shows the queen figure directly in the size selector. If keeping the spend low is the priority, our best mattresses for side sleepers includes options across price bands.

Who should not pick each mattress?

Skip the AS3 all-foam if you already know you sleep better on a firm or soft surface, since only medium is offered in this model. Skip it if you want a long trial, since 100 nights is the shortest window in this comparison, or if you specifically want coils, which belong to the separate AS3 Hybrid rather than the all-foam version reviewed here. Stomach sleepers who need a genuinely firm platform should also look at a firmer option before committing to a medium foam bed.

Skip the Signature Hybrid if you want an all-foam bed with no coils at all, if you prefer a single curated feel rather than choosing among three, or if a 12-inch profile matters for your frame or sheets. Shoppers who place a lot of weight on a chiropractic endorsement or a chiropractor-approved claim will find that story on the Amerisleep side, while Brooklyn leads with factory-direct pricing and construction control.

Is the Saatva Classic a better fit than either?

The Saatva Classic is the strong alternative when neither of these two is quite right. It is an innerspring mattress with a 3-inch Euro pillow top, a dual-coil design of over 1,000 triple-tempered recycled carbon steel coils in full size and up, and patented Lumbar Zone technology for spinal alignment. Where the Signature gives you three firmnesses, Saatva gives you three comfort levels as well: 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 all-position choice, and Firm at 8 out of 10 for stomach and back sleepers. You also choose between an 11.5-inch and a 14.5-inch profile.

Against the AS3, Saatva trades the foam contouring and the Refresh cooling cover for a pillow top and a coil-based support system, and swaps the 100-night trial for a 365-night home trial with a lifetime warranty. Against the Signature, it matches the firmness choice and adds white-glove delivery with in-room setup and free removal of your old mattress, which neither of the two compared mattresses offers. The Saatva Classic queen lists at $1,895, above both, and it is CertiPUR-US certified and GREENGUARD Gold certified with an American Chiropractic Association endorsement.
