Our Review Process: Each mattress we review undergoes a rigorous evaluation process. We assess comfort, support, cooling, and durability through both subjective experiences and objective tests.

Criteria include pressure relief, spine alignment, mattress responsiveness, motion transfer, edge support, and temperature regulation. This comprehensive approach ensures our reviews are thorough and unbiased.

I. Mattress Layers, Materials and Construction

The AS3 Hybrid features multiple layers of high-quality materials.

Support Layers

At the base is a thin foam that provides structure and durability. Above that sits the pocketed coil layer, containing individually wrapped coils for bouncy, customized support. These compress to relieve pressure while keeping the spine properly aligned. I noticed a nice bounce and better edge support compared to all-foam models thanks to these coils.

Comfort Layer

The specialized Bio-Pur® foam rests between the coils and the cover. Amerisleep describes this proprietary foam as highly breathable and responsive. Indeed, I never felt stuck in the mattress—likely due to the quick reaction time of Bio-Pur®.

Mattress Cover

Finally, the Refresh Cooling Cover on top uses a scientifically designed mineral infusion meant to convert body heat into infrared energy. This improves blood flow for faster muscle recovery and better sleep. I found this cover maintained a refreshing coolness all through the night.

II. Sleeping Positions

The Amerisleep AS3 Hybrid mattress caters to a wide range of sleeping positions due to its medium firmness level and balanced combination of cushioning and support. Let’s take a closer look at how this mattress performs for different types of sleepers.

Side Sleepers

The AS3 Hybrid is an excellent mattress for side sleepers. I found its medium firmness level provides the perfect balance of cushioning and support, ensuring proper spinal alignment and pressure relief for the shoulders and hips in my tests.

The conforming Bio-Pur® foam contours to the body’s curves, while the supportive coils prevent excessive sinking. This combination creates a comfortable and pressure-relieving surface that side sleepers need to maintain a healthy sleeping posture throughout the night.

Back Sleepers

Back sleepers also benefit from the AS3 Hybrid’s medium firmness and balanced support. The mattress offers enough cushioning to cradle the lower back and promote a neutral spine position. Simultaneously, the pocketed coils provide the necessary support to keep the spine properly aligned and prevent sagging.

This combination of comfort and support helps alleviate back pain and ensures a restful night’s sleep as a mattress for back sleepers.

Stomach Sleepers

While the AS3 Hybrid may not be the perfect fit for all stomach sleepers, it can still provide a comfortable sleeping surface for those who prefer this position. The medium firmness level offers enough support to keep the hips from sinking too deeply, which is crucial for maintaining proper spinal alignment in a mattress for back sleeping.

However, some stomach sleepers, especially those with higher body weights, may prefer a slightly firmer mattress to ensure optimal support and prevent lower back strain.

Combination Sleepers

Combination sleepers, who change positions throughout the night, will appreciate the AS3 Hybrid’s versatility. The responsive Bio-Pur® foam and bouncy coils make it easy to switch positions without feeling stuck, establishing the mattress for combination sleepers.

The medium firmness level accommodates various sleeping positions, providing a balance of pressure relief and support for side, back, and stomach sleeping. This adaptability ensures that combination sleepers can find comfort no matter which position they shift to during the night.

Different Body Types and Weights

The AS3 Hybrid’s medium firmness and supportive coil layer make it a good choice for a wide range of body types and weights. However, sleepers over 230 lbs may find the mattress slightly less supportive and might prefer a firmer option.

Lightweight sleepers under 130 lbs, on the other hand, may find the mattress a bit too firm and could benefit from a softer variation.

III. Response Time

A responsive mattress surface is crucial for providing comfort and support during sleep. It allows the mattress to adapt quickly to changes in body position, ensuring proper spinal alignment and reducing pressure points. This responsiveness enhances overall sleep quality by facilitating ease of movement and minimizing disturbances, contributing to a more comfortable and restful night’s sleep.

Amerisleep designed the responsive Bio-Pur® foam to prevent feeling stuck on the AS3 Hybrid. I validated this through “response time tests” using 10-lb weights, my usual method of gauging a mattress’s quickness to adapt and regain its shape. Dropping these onto the mattress surface, I gave high marks when they bounced back up quickly rather than remaining indented.

The AS3 Hybrid earned an 8/10 in responsiveness with moderate sink but no feeling of fighting my way out. This made moving around a breeze without compromising comfort.

IV. Motion Transfer and Edge Support

For couples, motion transfer matters greatly. Too much movement crossover could disrupt your partner or even wake you from sleep.

But the AS3 Hybrid scored an impressive 8/10 in my motion transfer tests. Lying down and moving side to side, I watched 10-lb weights for disturbance. They hardly budged, affirming that isolated coil-foam construction. Most partners should sleep soundly even if the other changes position on this motion-isolating mattress.

The coil layer also did wonders for edge support versus all-foam alternatives. Sitting and fully extending my body weight on the perimeter, I encountered a clearly defined, sturdy edge.

The AS3 Hybrid earned top marks here with a 9/10 edge support score. I had no fear whatsoever of sliding off or bottoming out at the sides as on some mattresses. This also expands the usable real estate of the bed.

V. Cooling and Breathability

A cooling mattress is important because it can help regulate body temperature during sleep, which is crucial for initiating and maintaining a restful sleep cycle. By preventing overheating and promoting a comfortable sleeping environment, a cooling mattress may improve sleep quality,

A recent 2024 study 1 Verified Source National Library of Medicine (NIH) World’s largest medical library, making biomedical data and information more accessible. See the source reinforced this by concluding that cooling the body during sleep led to an increase in slow wave sleep (N3) by an average of 7.5 minutes over a period of 7.5 hours. Additionally, there was a decrease in heart rate during sleep. However, there was no significant change observed in the duration of REM sleep.

The proprietary cooling cover shone brightly when testing the breathability of the AS3 Hybrid. I consistently noticed refreshing coolness from first contact to waking each morning. The integrated cooling minerals in the revolutionary Refresh cover seemed to actively pull away body heat, contributing to 10/10 cooling.

Compared to other hybrid mattresses I’ve tested, such as the Leesa Hybrid and the Casper Wave Hybrid, the AS3 Hybrid stands out for its exceptional cooling properties. The combination of the Refresh Cooling Cover and the Bio-Pur® foam provides a more consistent and effective temperature regulation system.

The mattress’s perfect score puts it in good company with the other Amerisleep mattresses I’ve reviewed, showing how exceptional coolness is a trait the brand strives for in every mattress. It’s also comparable to other luxury hybrid mattresses I’ve tested that focused on cooling:

When evaluating the AS3 Hybrid against the Brooklyn Bedding Aurora Luxe Hybrid, both mattresses offer exceptional cooling properties. However, the AS3 Hybrid’s Bio-Pur® foam and Refresh cover technology provide a unique approach to temperature regulation, compared to the Aurora Luxe Hybrid’s combination of CopperFlex™ foam and TitanCool™ fabric.

While the surface and mattress cover was what I first noticed, when I examined the mattress’s layers and features more deeply, I was struck by how much the AS3 Hybrid was committed to being a cooling mattress from top to bottom.

The wrapped coils not only ensure top-tier motion isolation and support, but also provide ample amount of space for air to flow inside the mattress, preventing heat from accumulating.

The Bio-Pur® layer uses an advanced open-cell structure, allowing significantly more airflow than standard memory foam to keep you cool and comfortable all-night long. No more tossing and turning while sweating thanks to this breathable plant-based foam.

Hot sleepers like myself can rest assured they’ll stay chill through the night on this particular cooling mattress. Even better, the cover helps rejuvenate muscles overnight through enhanced circulation from infrared energy.

VI. Durability and Longevity

All Amerisleep beds like the AS3 Hybrid come backed by a 20-year warranty—a true rarity in the mattress industry. This gives me great confidence in investing in their product, knowing they fully expect it to last 20 years or more under normal use.

The pocketed coils inside the AS3 Hybrid go a long way toward deterring mattress sagging or body impressions. Each coil is encased in its own fabric pocket, allowing it to move independently. This reduces the overall wear and tear on the mattress since pressure and movement are distributed more evenly.

Additionally, pocketed coils help to minimize motion transfer, meaning movements from one side of the bed are less likely to disturb the other side. This decreased strain on the mattress structure can lead to a longer lifespan compared to mattresses with interconnected coils.

With quality construction in American-made facilities, Amerisleep clearly stands behind their work too. The metal coils, durable foams and woven cover each felt solidly made when I analyzed them up close. I anticipate decades of life from this mattress barring accidents or abuse.

VII. Potential Drawbacks

New Mattress Smell

When initially unboxing the AS3 Hybrid, I noticed a faint off-gassing scent—likely residual from the manufacturing process. As someone quite sensitive to smells, this dissipated within 15-20 minutes after exposure to open air. While most sleepers probably would barely detect this, it’s worth noting for the extra sensitive like myself.

Hybrid Design

It’s also key to recognize this mattress contains metal coils rather than being 100% foam. That allows great bounce, edge support and airflow but means slightly less potential pressure relief perhaps.

Mattress Firmness

With a medium feel, the AS3 Hybrid may not optimize either firmness extreme. Soft mattress lovers or those wanting an extra-firm bed would need to look at other models.

Still, while a firmer or softer bed may better target individual positions, the AS3 Hybrid provides wide appeal.

Motion Isolation

While the AS3 Hybrid performs well in motion isolation, it may not be as effective as all-foam mattresses like the original Amerisleep AS3 or the Zoma Start. Couples who are especially sensitive to motion transfer may prefer these all-foam alternatives.

If a hybrid mattress is a necessity, there are models I’ve reviewed that have scored perfect scores for motion isolation.

Mattress Price

I should also note that along with feeling different to a foam mattress, a hybrid like this is also more expensive than a pure foam bed, due to its mix of high-quality materials.

This means that for anyone who is seeking to maximize their dollar’s value with a high-quality budget mattress, a bed like the original Amerisleep AS3 memory foam mattress may be more suitable.

IX. Customer Reviews

Beyond my own testing, countless Amerisleep customers validate the exceptional benefits of the AS3 Hybrid. The following customer reviews were sourced from the Amerisleep website and third-party review platforms, providing a combination of verified buyer experiences and feedback:

  • Josh from Colorado says it alleviates his joint stiffness so much he despises sleeping elsewhere now.
  • Jen in Virginia Beach praises its “not too soft yet not too firm” feel.
  • Jose applauds its cooling and motion isolation.
  • Shelly calls attention to its pressure relief and Amerisleep’s superb customer service.

Not all reviews are flawless though. Alistair from Florida left only 3 stars, complaining he and his wife don’t feel well-rested on their AS3 Hybrid. But that’s the minority experience in a sea of rave reviews.

Testing the mattress at home yourself is the only way to know if you agree with happy customers or the rare dissatisfaction.

X. Environmental Impact

Part of what sold me on Amerisleep was learning about their sustainable company practices aimed at reducing environmental harm. From plant-based materials to zero-emissions manufacturing to efficient direct-to-consumer shipping, Amerisleep actively works towards greener operations.

Their eco-friendly mattresses also happen to be certified non-toxic and safe, something reassuring for health-conscious folks like me.

XI. Maintenance and Care

To help your AS3 Hybrid, already a durable mattress, last 20 years or beyond, Amerisleep shared with me some easy maintenance tips.

Though not required, using a mattress protector can further shield your investment from spills, stains, and other damage. The cooling cover conveniently unzips for throwing in the wash to freshen up whenever needed. Note you’ll want to line dry only to prevent damage.

Otherwise, no flipping or rotating of the mattress is necessary—just keep the printed side of the mattress facing upwards. Cleaning bed linens routinely keeps the mattress cleaner too.

XII. Final Verdict

In conclusion, I found the medium-comfort AS3 Hybrid to offer excellent pressure relief and support as a side sleeper. Cooling, breathability, motion isolation, and edge support also scored top marks in my evaluation.

Plus, Amerisleep wins my trust through their sustainable practices, certifications, warranties and rave customer reviews. A barely noticeable initial scent upon unboxing was the only detractor.

So if you want bounce and breathability from pocketed coils plus contouring comfort from foam, the AS3 Hybrid is a fantastic choice. I happily award this well-rounded mattress an 8/10 overall. It will provide most sleepers an extremely comfortable and cooling night’s rest for decades to come.
