I previously tested the memory foam Amerisleep AS3 mattress for over two months, finding that it complemented my sleep needs as a 180-pound side sleeper quite well. I was so curious, though, about what it would be like to sleep on the AS3 Hybrid counterpart, and EachNight was kind enough to give me the chance to review it and share my honest thoughts.

I know firsthand how pivotal quality rest is for mental and physical well-being. Using my decades of expertise in sleep health, I will evaluate all aspects of this mattress to provide a comprehensive analysis for shoppers seeking their perfect bed. Let’s dive in!

Suitability of the Amerisleep AS3 Hybrid mattress for various types of sleepers, as detailed by Dr. Colleen Ehrnstrom, Ph.D., ABPP.

Unboxing and Mattress Setup

The Amerisleep AS3 Hybrid arrived vacuum-sealed in a compact box, making delivery straightforward. Unboxing took just minutes – I removed the packaging, watched it quickly inflate to full size, and then placed it on my bed frame. The sleek, modern design made a fantastic first impression.

There was no bothersome off-gassing or chemical smell, earning it a perfect 1/5 rating for initial odors, with 1 used to indicate no bothersome smell and 5 for a strong scent. Just like their other mattresses, there were no discernable odors…. ever.

Premium Materials and Responsive Support

Examining the mattress layers, it was clear that Amerisleep utilized high-quality materials designed to provide comfort and support. The Amerisleep AS3 Hybrid mattress is designed for cooler, more comfortable sleep thanks to its advanced cover, thoughtfully engineered foam layers, and carefully arranged pocketed coils.

First, their cover is made with a unique fiber blend akin to Celliant. This innovative material is known for increasing airflow and transferring body heat away from the surface. The soft, breathable cover stayed cool to the touch as I pressed my hand to the surface to test its feel, and remained that way when I lied down to sleep.

Underneath the cover lies Amerisleep’s proprietary Bio-Pur® memory foam. This material contours to the body to cushion pressure points, while remaining bouncy and responsive. Unlike traditional memory foam, Bio-Pur foam was engineered by Amerisleep to sleep cooler through its advanced open-cell design.

The thick base of resilient, individually wrapped springs added bounce, improving ease of movement. After weeks of testing, the mattress showed no signs of impressions or sagging.

The edge support was exceptional, thanks to the sturdy pocketed coil hybrid design. Much better than what the memory foam-only mattress offered, as I covered in my Amerisleep AS3 review. I give the hybrid a 4 out of 5 in this category.

It maintained its structure night after night. I was thoroughly impressed by the exquisite craftsmanship and gave it a perfect 5/5 durability rating. While it is a new mattress still, I have no concerns about how long it is going to last.

Cushioned Yet Supportive Medium Feel

On the 10-point firmness scale, I’d rate this mattress around a 5.5, right in the medium sweet spot. This is when neither a 1 nor a 5 is the best score out of five, as I would consider those reserved for extremely soft or firm feels. But the AS3 Hybrid was a top-tier 4 out of 5 when it cam to firmness, feeling supportive yet ready to cradle me.

Lying down, I felt gentle contouring and pressure relief with adequate support for my frame. The quick response foams adapted to my shape while preventing sagging around the hips. I would give the AS3 a perfect 5/5 when it comes to its support and comfort!

Consistent Comfort in All Sleep Positions

I tested the mattress in both my preferred back and side sleeping positions. Each time, my spine remained properly aligned with no uncomfortable sinking.

There was excellent edge support and stability across the mattress’s entire surface. Despite my weight, I didn’t sink in excessively or feel enveloped by the bed.

The support and comfort remained consistent over my many nights of testing and in all sleeping positions – a true feat. For this, I give the Amerisleep AS3 Hybrid a perfect 5/5 pressure relief score.

Minimal Motion Transfer

This hybrid mattress isolated motion extremely well. I barely noticed my partner’s movements throughout the night, even when changing positions or getting in/out of bed. For motion isolation, it earns top marks.

Moving itself was also an easy task. The buoyant foams and coils rebounded rapidly, so I never felt “stuck” in an impression. It was comfortable sitting on it and reading or while sleeping.

Cool, Sweat-Free Sleep

As someone prone to sleeping hot, I was thrilled the Amerisleep AS3 Hybrid slept cool and comfortable, even during warm summer nights. I tested it through variable temperatures and slept comfortably without any heat-related disturbance.

The strategic airflow design and breathable materials wicked away heat and moisture, preventing sweaty awakenings. I stayed blissfully cool without needing extra fans or blankets.

For temperature regulation, this exceptional mattress earns another perfect 5/5 rating.

Ultimate Value and Satisfaction

Considering the exceptional craftsmanship, premium materials, and sheer comfort of the Amerisleep AS3 hybrid mattress, I believe it provides top-tier value.

It outperforms competitors that charge double the price, offering an unparalleled sleep experience for years to come. For shoppers seeking the perfect balance of support, comfort and breathability, the AS3 Hybrid is a worthwhile investment.

My one quibble is that this mattress is heavy. However, I can’t imagine you can do much about that, as it reflects the benefits of the materials and the bed itself.
