Embarking on a quest to find the perfect mattress can be an overwhelming journey, but Amerisleep could be the ultimate destination. Imagine Amerisleep as the ‘Goldilocks’ of mattresses, where there’s a perfect fit for everyone. Whether you crave the cloud-like softness of foam, the sturdy support of a hybrid, or the eco-friendly comfort of an organic mattress, Amerisleep has your dream bed waiting. From the ultra-plush AS5 to the very firm AS1, they’ve meticulously crafted a sleep solution that caters to your unique needs.

This review looks at Amerisleep’s most popular model: the AS3. As a husband and wife team with a shared passion for quality sleep and innovation, we had the opportunity to test the Amerisleep AS3 personally. We’ll share our experience and cover details like the mattress’s construction, firmness, support, and unique features.

Amerisleep AS3 YouTube Review

Firmness & Feel of the Amerisleep AS3

The AS3 mattress is an excellent choice for those who want a blend of contouring and support. We rated it a 6.0 out of 10 on the firmness scale, which puts it in the medium range, making it ideal for most body types and sleep preferences. The AS3 features zoned construction, which provides targeted pressure relief and support, resulting in a comfortable and restful sleep. Let’s look at how it feels based on your preferred sleeping position!

Firmness Scale 1-10 highlights a 6.0 or medium firmness.

Is The AS3 Suitable For Side Sleepers?

As a side sleeper, I struggle with sleep-induced pain in my hips and shoulders, so finding a mattress that can effectively ease pain through these stubborn pressure points is essential. I was impressed with how well the AS3 delivered the relief I needed without compromising support.

Still, some side sleepers might lean towards an even plusher feel. For those folks, Amerisleep has you covered with the  AS5, specially designed for side sleepers who want that extra touch of softness. Nonetheless, the AS3’s “medium” feel is a crowd-pleaser, catering to a wide range of sleep styles, including couples with different firmness level preferences.

Is The AS3 Suitable For Back Sleepers?

If you’re a back sleeper, you’re in for a treat! The ideal mattress for back sleepers not only keeps your spine aligned but also offers optimal cushioning for a comfortable night’s rest.

The Amerisleep AS3 mattress is an excellent choice for back sleepers, thanks to its perfect balance between comfort and support. Its medium firmness gently embraces your body, cushioning your joints while keeping your spine in a healthy alignment. You’ll feel this gentle embrace as soon as you lay down, especially in your lower back. Unlike other mattresses, it doesn’t sag or hammock, which can cause your body to get out of alignment and lead to discomfort.

Is The AS3 Suitable For Stomach Sleepers?

The AS3, with its medium firmness, might not be optimal for those who prefer to sleep prone. Stomach sleepers need a firmer mattress to avoid spinal misalignments that could cause discomfort or back pain.

If you’re a stomach sleeper, consider one of Amerisleep’s firmer options for that extra dose of support. The AS1 (firm) and the AS2 (medium-firm) have been designed specifically for back and stomach sleepers.

Putting the Amerisleep AS3 to the Test

Cooling

Amerisleep utilizes innovative technologies to promote a cooler, more breathable sleep experience. Unlike traditional memory foam mattresses notorious for heat buildup, Amerisleep’s secret lies in Bio-Pur, an open-cell, plant-based foam. This material delivers the sought-after pressure relief of memory foam while ensuring a significantly cooler night’s sleep.

Additionally, Amerisleep’s mattress cover is designed to draw heat away from your body and convert it to far infrared energy. This makes for a cooler sleep surface, improves circulation, supports quicker muscle recovery, and improves sleep quality.

As someone who tends to sleep hot, I understand the importance of temperature regulation for an uninterrupted night’s rest. The Amerisleep AS3 has proven to be one of the coolest all-foam mattresses I’ve tested, ensuring I sleep soundly and undisturbed.

Motion Isolation

Motion isolation is vital in a mattress because it minimizes the transfer of movement from one side of the bed to the other. This means that when your partner shifts or gets in and out of bed, their movements won’t disturb you. It’s particularly important for couples who share a bed, ensuring that both individuals can enjoy uninterrupted, restful sleep without being disturbed by each other’s motions during the night.

Memory foam mattresses tend to perform well in this category, and the AS3 was no exception. My husband and I experienced minimal motion transfer, allowing us to sleep through the night without disturbance. This indicates it could be a great choice for couples!

Edge Support

Edge support, or lack thereof, can significantly affect your overall comfort. Strong edge support ensures that you can utilize the full surface area of your mattress, making it feel more spacious. Conversely, a lack of edge support can make your mattress seem smaller and limit your sleeping space.

During our testing, we found that the Amerisleep AS3 demonstrated reliable edge support when lying near the edge. While we experienced some slight compression, it was minimal, and we didn’t feel at risk of rolling off the bed. However, we observed more noticeable compression when we tried sitting on the edge.

This aspect of edge support is particularly crucial if you have mobility concerns and rely on sturdy edge support for ease of getting in and out of bed. It’s worth considering how edge support aligns with your needs to ensure a comfortable and accessible sleep experience.
