by For most sleepers choosing between these two, I’d start with the all-foam AS3. It costs less at the current Queen price and keeps the surface feel consistent, with no coil bounce. Pick the AS3 Hybrid if you specifically want springs, easier movement across the bed, or a more buoyant feel under your hips and shoulders. Both are medium-feel, 12-inch Amerisleep mattresses with the same 100-night trial and 20-year warranty; the difference is what supports you underneath.
My quick call: AS3 for a close-hugging, quiet foam feel and lower upfront price; AS3 Hybrid for a springier response and stronger edge structure. Neither is automatically better for every body or sleep position. Your weight, preferred firmness, partner movement, and how much you like the sink of memory foam matter more than the word “hybrid.”

Which one should you choose?
- Choose the AS3 if you want the more affordable option, prefer the slower, closer contour of an all-foam bed, or want less bounce when you change position.
- Choose the AS3 Hybrid if you prefer a buoyant surface, want a coil support unit, or find it easier to reposition on a responsive mattress.
- Consider neither without trying the feel if you need a distinctly firm or distinctly plush mattress. Amerisleep lists both AS3 versions as medium.
I’d name the AS3 all-foam the best fit for the broadest group in this particular matchup, mainly because it costs less and avoids the extra bounce that some foam sleepers dislike. That is a value-and-feel recommendation, not a promise that one model suits every body. If you know you like coils, the Hybrid is not a compromise; it is the more natural pick.

What the extra $200 buys on the Hybrid
At the displayed Queen sale prices, the Hybrid is $200 more. That premium buys a different support core, not a different firmness label: both are sold as medium and both measure 12 inches tall on the product page. Amerisleep describes the Hybrid as foam layers paired with pocketed coils. Its product copy says the coil unit is designed to provide a buoyant response and firmer support around the mattress edges.
The AS3 also has more than one material layer. It uses Bio-Pur memory foam in the comfort system and HIVE technology for zoned contouring and support. But it does not have a coil unit. So the real choice is not “basic versus upgraded”; it is foam response versus foam-over-coils response. Pay the difference only if the latter is the feel you want.
There is a practical difference when you move. Foam generally compresses directly under your body and can feel more enveloping; coils push back more immediately. Amerisleep markets Bio-Pur as more responsive than traditional memory foam, so the all-foam AS3 should not be described as a slow, deeply sinking classic memory-foam mattress. Still, the Hybrid adds spring response from its pocketed coil layer.
How will each feel in different sleep positions?
Side sleeping
Both models are plausible starting points for side sleepers who want a medium feel. The foam AS3 may suit you if you want the shoulders and hips to settle into the comfort layers without a coilier sensation. The Hybrid may suit you if you want that pressure-relieving foam above a spring base that feels more lifted when you turn.
Here is the caveat: “medium” is the manufacturer’s feel description, not a guarantee that it will feel medium to every sleeper. If you are lighter, either mattress may feel firmer than expected; if you carry more weight, you may compress the comfort layers more. If you need a distinctly plush surface for pressure relief or a firmer, more level surface, compare other firmness options rather than assuming the Hybrid fixes that mismatch.
Back sleeping
For back sleeping, I would decide by your preferred response. If you like a close foam contour and do not want much bounce, start with the AS3. If you want your hips supported by a more buoyant base and value a coil unit, consider the Hybrid. Amerisleep markets both as medium, so neither has a verified firmness advantage over the other from that label alone.
Stomach sleeping
Stomach sleepers often prefer a firmer surface than a medium mattress, particularly if their hips sink too far. I would be cautious about either AS3 version if you already know you need firm support. The coil layer does not, by itself, prove that the Hybrid will feel firmer: Amerisleep lists both options as medium.
Combination sleeping
If you rotate among positions, the Hybrid’s pocketed coils may make its surface feel more buoyant as you move. The all-foam AS3 offers a more uniform foam sensation and Amerisleep describes its Bio-Pur as responsive. If you are unsure whether you like springiness, think about mattresses you have enjoyed before; do you prefer the quick push-back of coils or the steadier feel of foam?
Motion, edges, temperature, and noise
Motion isolation: foam is often the simpler choice if your priority is reducing the sensation of a partner shifting, because it lacks a coil support unit. The Hybrid uses individually pocketed coils, which differ from a connected innerspring system, and Amerisleep says its coil design isolates motion. That is a product claim, not a measured head-to-head result for these two models. If partner movement is a major concern, use the trial to decide whether the actual feel works for you.
Edge support: Amerisleep describes firmer, double-density coils at the sides of the Hybrid. That gives the Hybrid a clear structural reason to appeal if you sit or sleep near the edge. The all-foam AS3 does not have those perimeter coils. We did not find a comparable published edge-compression measurement for both beds, so this is a construction distinction rather than a lab-score claim.
Temperature: Amerisleep promotes its Refresh cover and Bio-Pur foam as cooling features on the AS3 range. Both beds share foam comfort materials, while the Hybrid adds space between coils that could allow a different airflow path. Do not treat “cooling” as a guarantee that you will sleep cool: bedding, room temperature, and personal heat sensitivity all matter.
Noise: an all-foam bed has no springs to produce coil noise. Pocketed coils are wrapped individually, but we do not have a verified noise test comparing these models. If you are especially sensitive to sound, the AS3 is the lower-uncertainty construction.
What is inside each mattress?
Amerisleep’s AS3 uses Bio-Pur, the brand’s plant-based memory foam, above its HIVE support technology. The company says Bio-Pur is open-cell and responds more quickly than conventional memory foam. HIVE is a zoned layer intended to contour differently across parts of the body. Those descriptions explain the design; they are not independent medical evidence or a promise of pain relief.
The AS3 Hybrid keeps the foam comfort concept but adds a pocketed coil support unit. Amerisleep describes the coils as bouncy and supportive, and says denser coils along the sides strengthen edge support. That is the key engineering distinction for buyers: a foam-based top feel with spring support below.
Both models are listed at 12 inches high. Amerisleep also describes both as fiberglass-free and says mattresses are made in the USA from U.S. and imported components; the product page notes that covers are sewn in Canada. If country of origin or material details affect your purchase, check the current label and product documentation for the exact size you order.
Trial, returns, delivery, and warranty
Amerisleep offers a 100-night trial on both versions and says free shipping and returns are included. Its AS3 Hybrid page says that if you do not love the mattress after the first 30 nights, customer support can arrange a full refund. The 30-night minimum matters: do not assume you can request a return immediately after delivery. Read the current return terms at checkout and ask Amerisleep how pickup or donation is handled in your area.
Amerisleep lists a 20-year warranty for both. A warranty is not the same as a sleep trial or a comfort guarantee: it covers only defects and circumstances defined in the warranty document. Check the current terms for exclusions, required foundations, and the process for making a claim.
The foam AS3 ships within 3–7 business days; the Hybrid can ship a little faster, within 1–7 business days. That is an availability estimate, not a promised delivery date; verify the estimate for your ZIP code and selected size before ordering. Free shipping is listed for both models.
Who should NOT buy either one?
- Skip both if you know you need a distinctly firm mattress. Both AS3 versions are listed as medium.
- Look elsewhere if you want a very plush, deep pillow-top feel. Neither product page describes the AS3 as plush.
- Do not pay extra for the Hybrid if you dislike bounce. Its coil system is specifically described as buoyant.
- Do not assume the Hybrid solves every support issue. The shared medium label means the change is mainly construction and response, not a documented firmness upgrade.
- Do not rely on a mattress to treat a medical condition. If pain or sleep symptoms are persistent, discuss them with a qualified clinician.
How we compared
Our verdict
For the broader value pick, I’d choose the all-foam AS3. It gives you the same stated medium feel, 12-inch height, trial, and warranty as the Hybrid at a lower Queen price. Its all-foam construction is also the more straightforward choice if you prefer less bounce and a quieter, more contained feel.
Choose the AS3 Hybrid when you actively want coils. The added $200 at the displayed Queen sale prices buys a buoyant spring support unit and the firmer perimeter-coil design Amerisleep describes. If those are meaningful to you, the Hybrid is worth the premium. If you cannot name a reason you want coils, save the money and start with the AS3.

Frequently asked questions
Is the AS3 Hybrid firmer than the AS3?
Amerisleep lists both as medium. The Hybrid has pocketed coils and a more buoyant construction, but that alone does not establish that it is firmer. Consider the feel you prefer rather than assuming “hybrid” means “firmer.”
How much more does the AS3 Hybrid cost?
On Amerisleep’s product pages, the Queen sale prices are $1,249 for the all-foam AS3 and $1,449 for the Hybrid, a $200 difference. Those pages also display regular prices of $1,749 and $1,949, respectively. Promotions and prices can change, so confirm your selected size and current total with Amerisleep.
Do both mattresses have a 100-night trial?
Yes. Amerisleep advertises a 100-night trial for both. Its AS3 Hybrid page says to allow the first 30 nights before requesting a return. Confirm the current terms directly before buying.
Which one is better for side sleepers?
Either may suit a side sleeper who likes a medium feel. Choose the foam AS3 for a more contained foam sensation; choose the Hybrid if you want the same general medium positioning with extra spring response. Your body weight and preferred softness can change how either feels.
Does the AS3 Hybrid sleep cooler?
Amerisleep promotes cooling features on both versions and describes the Hybrid as pairing foam with coils. The product information does not establish a verified head-to-head temperature advantage for one AS3 over the other.
Is the AS3 Hybrid worth the extra money?
It can be if you want a pocketed-coil support layer and the springier feel that comes with it. If you prefer all-foam comfort and do not care about coils, the lower-priced AS3 is the stronger value for you.
