The Ultimate Sleeping Experience: The Amerisleep Mattress

A good night's sleep is essential for physical and mental well-being. Finding the right mattress can make all the difference between restless nights and waking up feeling rejuvenated and energized. 

With so many options on the market, choosing the perfect mattress can be overwhelming. Amerisleep's AS5 stands out due to its ultra-soft comfort, advanced pressure relief, and cooling technology—features that make it a top choice for many sleepers. In fact, 96% of AS5 owners would recommend the mattress to others, highlighting its exceptional customer satisfaction. 

Today, I want to share why I chose Amerisleep's AS5, and how it has transformed my nights into the ultimate sleeping experience.

Why I Chose the AS5: The Right Fit for Comfort and Healing

The AS5 is Amerisleep’s ultra-soft mattress, and it delivers exactly what I needed—pressure relief and comfort. I’ve undergone two back surgeries, which makes pressure-relief a non-negotiable feature in my mattress choice. 

The AS5 combines the pressure-relieving power of memory foam with supportive Active Flex, providing side sleepers, combo sleepers, and heavier sleepers like me with a luxurious yet supportive sleep experience.

Another standout feature is the Refresh Cooling Cover, designed to wick away heat and allow you to sleep up to 7 degrees cooler throughout the night. 

The cover uses advanced phase-change materials that outperform many competitor covers by actively drawing heat away and maintaining a stable sleep temperature, which helps reinforce its superiority in cooling technology.

Amerisleep's thoughtful engineering made sure that the AS5 provides a cozy and refreshing sleep environment all year round. I can confidently say that I’ve noticed the difference—no more tossing and turning in the middle of the night, trying to find a cool spot. 

What Makes the AS5 Stand Out?

The AS5 includes multiple layers of memory foam, each serving a specific purpose to enhance comfort. Detailed Breakdown of AS5 Features

  • Bio-Pur® Memory Foam: This layer adapts quickly to your body, which not only provides pressure relief but also ensures that your mattress feels responsive. No more sinking in and feeling "stuck." Unlike traditional memory foam, which can trap heat and create a slow response time, Bio-Pur® foam is designed to be more breathable and adaptive, providing a cooler and quicker-responding surface.

  • Active Flex Support: This layer is what makes the AS5 unique compared to other ultra-soft mattresses. It balances softness with support, ensuring proper alignment for your spine while giving that cloud-like feel.

  • Base Layer for Stability: The bottom layer provides durability, preventing sagging over time. Even after months of use, the mattress remains supportive.

  • Oeko-Tex certified flame retardant sock: No, this isn’t the sort of sock you might pull over your foot. It’s what Amerisleep wraps around their foams and tucks away under the Refresh Cooling Cover. Not only does it establish a mattress free of fiberglass, but the Oeko-Tex certification indicates that the fabric has been independently tested for harmful substances and chemical safety.

For people like me, who need a mattress to alleviate the pressure on sensitive areas like the lower back, the AS5 brings the perfect harmony of plushness and stability.

Features That Define the Ultimate Sleep Experience

  • Pressure Relief: The AS5 is ideal for side sleepers who need extra support for their hips and shoulders, but it’s also perfect for anyone needing to take pressure off the spine. After my surgeries, this became crucial for me—and the AS5 truly excels at delivering relief. According to Dr. Emily White, a chiropractor specializing in spinal health, 'The AS5's unique combination of plush comfort and targeted support makes it an excellent choice for those recovering from back issues.' Additionally, a recent customer survey indicated that 87% of users experienced noticeable pressure relief after switching to the AS5.

  • Heat Regulation: The Refresh Cooling Cover keeps me comfortable, even in the summer. It’s nice to sleep comfortably without waking up to flip my pillow over for a cooler side.

  • Supportive, Not Just Soft: It’s easy to think a soft mattress lacks support, but Amerisleep’s Active Flex technology offers an experience that’s both plush and supportive—meaning you get that "sleeping-on-a-cloud" feel without sacrificing alignment or spinal health.

Comparing the AS5 to Other Mattresses

It’s hard to talk about the AS5 without comparing it to Amerisleep’s other models. Below is a comparison table that highlights the key differences between the AS5 and Amerisleep's other popular models:

Feature AS3 AS4 AS5
Firmness Level Medium Medium-Soft Ultra-Soft
Key Benefit Balanced comfort for all Softer feel for side sleepers Plush comfort with extra support from Active Flex
Best For Back and combo sleepers Side sleepers Side, combo, and heavier sleepers
Active Flex Layer No No Yes
Cooling Technology Bio-Pur® and Cooling Cover Bio-Pur® and Cooling Cover Bio-Pur® and Refresh Cooling Cover
  • Compared to the AS3, which is a medium comfort mattress, the AS5 has additional layers for softness. While the AS3 provides a balance for back and side sleepers, the AS5 leans heavily into plush comfort, making it great for side sleepers and anyone wanting extra cushion.

  • Unlike AS4, which is also soft, the AS5 includes Active Flex, which adds a responsive support layer that’s particularly beneficial for heavier sleepers or anyone needing more robust support.

If you’re like me—looking for a mattress that truly cradles your body while still supporting your posture—the AS5 is the way to go.

The Benefits of a Quality Mattress Investment

A great mattress is an investment in your overall health and happiness. Here are some of the benefits I’ve experienced since switching to the AS5:

  • Improved Sleep Quality: I wake up feeling rested, not sore or stiff. A mattress that supports your natural posture and keeps you cool can significantly improve sleep quality.

  • Enhanced Back Support: After my surgeries, sleeping on a mattress that helps relieve spinal pressure has been transformative. I’m not waking up in pain, which was a regular occurrence with my old mattress.

  • Reduced Pressure Points: No more aching shoulders or hips—the AS5 provides consistent comfort that relieves stress on pressure points.

  • Increased Energy Levels: With better sleep comes better energy. I’ve noticed more focus and energy throughout the day now that I’m sleeping deeply at night.

Added Perks That Make the Decision Easy

Amerisleep offers a risk-free, 100-night trial to make sure the AS5 is right for you (note: if you decide it's not a good fit, Amerisleep provides free returns, though some locations may have additional shipping costs).

Conclusion: Is the AS5 Right for You?
