I. Mattress Layers, Materials and Construction

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

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®.

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

As a medium firmness mattress, the AS3 Hybrid struck an ideal balance for my side sleeper preferences. I felt it cushioned my shoulders and hips properly without excessive sinking. I’d imagine back and stomach sleepers finding decent support as well at this mattress firmness level.

The mattress could suit those who shift sleeping positions too, with its blend of contouring and lift establishing a good mattress for combination sleepers. While a firmer or softer bed may better target individual positions, the AS3 Hybrid provides wide appeal.

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

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.

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.

VIII. Trial Period, Warranty, Pricing and Sizes

Amerisleep comfort returns through an exceptional 100-night risk-free home trial. If you ultimately don’t love your AS3 Hybrid, contact their customer service team to coordinate pickup and a full refund.

Their 20-year warranty also promises free repairs or replacements for defects in that generous window. These perks provide ample opportunity to experience the benefits of the AS3 risk-free.

As a hybrid mattress, the AS3 Hybrid costs a bit higher than foam mattresses. However, it offers materials and engineering more premium than common beds in a box. Financing options are available, too, which help split costs over time.

The hybrid mattress comes in all standard mattress sizes: twin, twin XL, full, queen, king California king, and split king. The exact dimensions for each size are listed on Amerisleep’s website, helping match needs correctly to your bedroom’s space.

IX. Customer Reviews

Beyond my own testing, countless Amerisleep customers validate the exceptional benefits of the AS3 Hybrid:

  • 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.
