Who is the Amerisleep AS3 Best Suited For?
Now that we’ve covered the basics, let’s delve into who would benefit most from the Amerisleep AS3 mattress.
Ideal for Back Sleepers
Back sleepers, particularly those with average body weight, will find the AS3 to be an excellent fit. Its medium-firm feel provides adequate support to maintain proper spinal alignment.
Perfect for Side Sleepers
If you’re a side sleeper, you’re in for a treat. The AS3 offers just the right amount of sinkage to cradle your hips and shoulders, keeping your spine aligned and ensuring a comfortable night’s sleep.
Lightweight Stomach Sleepers
For lightweight stomach sleepers , the AS3 offers the right balance of support and comfort. It prevents excessive sinking in the hips, which can lead to spinal misalignment.
Memory Foam Enthusiasts
If you love the contouring feel of memory foam but dislike the heat retention often associated with it, the AS3’s Bio-Pur foam is a game-changer. Its open-cell structure promotes airflow, keeping you cool and comfortable.
Who Should Consider Other Options?
While the Amerisleep AS3 is an exceptional mattress, it may not be suitable for everyone.
Strict stomach sleepers typically require a firmer mattress to prevent excessive sinking at the hips. If you fall into this category, you might want to explore Amerisleep’s firmer models.
Those Seeking Bounce
If you prefer a mattress with a noticeable bounce, the AS3 may not meet your expectations. It’s an all-foam mattress, which doesn’t provide the same level of bounce as spring mattresses.
Firmness Level of the Amerisleep AS3
Firmness is a crucial factor when selecting a mattress, and the AS3 hits the sweet spot for most sleepers. On a scale of 1 to 10, with 10 being the firmest, the AS3 rates at a comfortable 6. This places it in the medium-soft category, which is ideal for those who appreciate both contouring and support.
The AS3’s unique firmness level caters to a broad audience, making it a top choice for couples with varying sleep preferences. However, it’s worth noting that you’ll experience a bit of “sinkage” on this mattress, which is essential for pressure relief but may affect combination sleepers .
Performance of the Amerisleep AS3 Mattress
Now, let’s explore the AS3’s performance in various scenarios, considering different sleeper types and needs.
Light Sleepers (Under 130 Pounds)
- Light Back Sleepers: The AS3 offers excellent support and comfort for light back sleepers, ensuring a restful night.
- Light Side Sleepers: This mattress excels for light side sleepers, providing the necessary sinkage to keep the spine aligned.
- Light Stomach Sleepers: Stomach sleepers in this weight range might find the AS3 a touch too soft. It’s advisable to opt for a firmer mattress to maintain proper spinal alignment.
Average Weight Sleepers (130 – 250 Pounds)
- Average Weight Back Sleepers: The AS3 is well-suited for most average weight back sleepers, although those with back pain may consider models with firmer support .
- Average Weight Side Sleepers: This mattress is a winner for average weight side sleepers, offering excellent cushioning for pressure relief.
- Average Weight Stomach Sleepers: Just like their lighter counterparts, average weight stomach sleepers might need a firmer mattress for optimal support.
Heavy Sleepers (Over 250 Pounds)
- Heavy Back Sleepers: The AS3 may not provide enough support for heavier back sleepers. Consider the AS4 with additional layers for better support.
- Heavy Side Sleepers: For heavy side sleepers, the AS5 with extra layers is the superior choice for sinkage and pressure relief.
- Heavy Stomach Sleepers: The AS3 and other Amerisleep models may not offer the necessary firmness for heavy stomach sleepers. Explore mattresses specifically designed for heavier individuals.
Pain Relief Performance
A crucial aspect of mattress selection is pain relief, especially for those dealing with discomfort in sensitive areas like the hips, shoulders, and lower back. To assess the AS3’s pain-relieving capabilities, we conducted a pressure map test.
- Back Pain: The AS3 evenly distributes body weight, making it an excellent choice for back pain sufferers. However, individuals with higher body weight may prefer a firmer mattress for added support.
- Shoulder Pain: This mattress excels at alleviating shoulder pain , thanks to its memory foam construction that cushions joints effectively.
- Hip Pain : For light sleepers with hip pain, the AS3 offers substantial relief. However, those with average or heavy body weight may benefit from the plusher AS4 or AS5.
Performance for Couples
If you share your bed with a partner, there are specific factors to consider. Let’s explore how the Amerisleep AS3 performs in this context:
The AS3 boasts exceptional motion isolation. You’re unlikely to feel your partner’s movements during the night, ensuring uninterrupted sleep. Memory foam mattresses excel in absorbing motion, making this mattress an excellent choice for couples.
While the AS3 may not provide the same bounce as spring mattresses, it still offers reasonable responsiveness. You should be able to move comfortably during intimate moments without feeling excessively stuck.
The AS3 is equipped with cooling technology to regulate temperature effectively. Its breathable cover and aerated Bio-Pur foam help dissipate heat, ensuring a cool and comfortable sleep environment for couples.
Decent edge support is essential for couples who want to maximize their sleeping surface. While the AS3’s edge support is not the strongest, it offers sufficient stability, preventing premature sagging and ensuring a comfortable sleep experience.
Construction of the Amerisleep AS3
Understanding the construction of a mattress is crucial for making an informed decision. The Amerisleep AS3 is an all-foam mattress with three distinct layers, totaling 12 inches in height. Let’s break down its construction:
The AS3 features a Refresh Cooling Cover, designed to wick away body heat, promoting cooler and more comfortable sleep. Additionally, the cover incorporates minerals that enhance daily performance and energy levels.
The top layer of the AS3 consists of 3 inches of Bio-Pur foam. This layer offers a slow response to pressure, allowing you to sink comfortably into the mattress while providing excellent pressure relief. Notably, Amerisleep’s proprietary foam is plant-based, reducing its environmental impact.
Beneath the comfort layer lies a 2-inch HIVE transition layer. This foam is slightly firmer and serves as both a transition between the soft memory foam above and the firm base below and provides bounce for ease of movement. Its convoluted design enhances temperature regulation and cooling.
The foundation of the AS3 comprises a 7-inch layer of Bio-Core foam. This high-density foam provides the necessary support for the comfort and transition layers, ensuring the mattress maintains its shape and longevity.
Unboxing and Off-Gassing
The Amerisleep AS3 arrives conveniently compressed in a box, ready to be unboxed at home. We recommend unboxing it with assistance, as it can be heavy and may decompress rapidly.
Like most bed-in-a-box mattresses, you’ll need to allow the AS3 between 24 and 72 hours to fully decompress. To ensure optimal off-gassing, place it in a well-ventilated room to allow any trapped gases to dissipate.
