In-Depth Look: Amerisleep AS3 Mattress Features & Considerations
Core Features & Consumer Benefits
The Amerisleep AS3 mattress integrates several key technologies aimed at enhancing sleep quality. Let's explore how these features translate into tangible benefits for you.
Bio-Pur® Material
Enjoy a cooler, more responsive sleep experience thanks to this plant-based, open-cell foam that wicks away heat and bounces back quickly.
HIVE® Technology
Experience targeted support and pressure relief with hundreds of hexagonal cutouts in the foam that conform to your body's five key zones.
Versatile Medium Feel
Ideal for side, back, and combination sleepers, the AS3 offers a balanced comfort that suits many body types and preferences.
Reduced Motion Transfer
Sleep undisturbed by a partner's movements due to the excellent motion isolation properties of the Bio-Pur® foam.
CertiPUR-US® Certified
Rest easy knowing the foams are made without ozone depleters, PBDEs, heavy metals, and other harmful substances, contributing to healthier indoor air quality.
Important Considerations & Potential Downsides
- Price Point
The AS3 is positioned as a premium mattress, which might be a significant investment for budget-conscious shoppers.
- All-Foam Construction
Those who prefer the distinct bounce and robust edge support of traditional innerspring or hybrid mattresses might find the AS3 different.
- Firmness for Strict Stomach Sleepers
While versatile, some dedicated stomach sleepers, especially those with higher body weight, might require a firmer mattress for optimal spinal alignment.
- Warmth (Relative to Hybrids)
Although Bio-Pur® is designed for cooling, very hot sleepers might still find hybrid or latex mattresses offer superior temperature regulation compared to an all-foam design.

Who Is the Amerisleep AS3 Mattress Best For?
Side Sleepers
The medium feel and HIVE® technology provide excellent cushioning and support for the shoulders and hips.
Back Sleepers
Offers a good balance of spinal support and pressure relief, promoting healthy alignment.
Couples
Minimal motion transfer ensures that movements on one side of the bed are less likely to disturb a sleeping partner.
Combination Sleepers
The responsive Bio-Pur® foam facilitates easy movement and position changes throughout the night.
Individuals Seeking Pressure Relief
The conforming foam layers help alleviate pressure points, which can be beneficial for those with joint pain.
Who Might Want to Explore Other Options?
- Strict Stomach Sleepers Over 230 lbs
May need a firmer mattress (like Amerisleep's AS1 or AS2) for better hip support and spinal alignment.
- Budget-Focused Shoppers
While offering good value, there are more budget-friendly memory foam options available on the market.
- Those Preferring a Very Firm or Very Soft Feel
The AS3's medium feel is designed for broad appeal, but some may prefer an extreme end of the firmness spectrum.
- Fans of Innerspring Bounce
If you enjoy the traditional feel and high responsiveness of coils, a hybrid or innerspring mattress might be a better fit.
