Inside ASL Reviews: Our Comprehensive Testing Process for Mattresses
- Last Updated: October 25, 2023

Welcome to the inner workings of ASL Reviews, where we take our passion for good sleep and put it to the test. In this article, we pull back the covers on our comprehensive testing methodology, delving into every critical aspect that makes a mattress worthy of your consideration.
But we don’t stop there; we’re on a mission to help you make informed choices, which means being candid about each product’s strengths and weaknesses. Whether you’re a side sleeper yearning for cloud-like comfort, a hot sleeper looking for the best cooling mattress, or a conscientious shopper with an eye for sustainability, we’ve got you covered.
In-Home Testing: A Personal Approach to Product Reviews
In the world of product reviews, making well-informed decisions can be challenging. At ASL Reviews, we believe that spending a few minutes testing a product in a studio doesn’t provide a complete picture of its long-term comfort and performance, especially regarding items that impact your sleep and daily life.
While many of our competitors opt for controlled studio testing, we take a personal approach. We live with and review products in our home, often for several nights or even weeks. This in-home testing allows us to uncover the subtleties and nuances that can significantly impact your daily life.
Our goal is not to criticize our competitors; it’s to provide you with the most comprehensive and honest reviews possible. We want you to make confident, well-informed decisions, knowing that the products we recommend have been thoroughly tested in real-world scenarios.
What We Look For When Testing A Mattress
There’s no one-size-fits-all solution when it comes to finding the perfect mattress. Every individual has unique sleep preferences and needs, which is why, at ASL Reviews, we take our mattress testing process seriously. We aim to provide comprehensive, honest, and insightful reviews to help you make an informed decision. Let’s look at the key factors we assess when putting a mattress to the test!
Firmness & Feel
The firmness of a mattress is crucial because it directly impacts your comfort. We evaluate whether a mattress is soft, medium, or firm; this helps you understand if it aligns with your personal preference, no matter whether you’re a side sleeper who craves plush comfort, a back sleeper seeking the perfect balance, or a stomach sleeper in need of extra support.
We also take into account the feel of the mattress. Is it responsive and bouncy, or slow-moving and contouring? The feel of a mattress plays a significant role in determining the overall comfort and suitability for different sleep preferences.
A responsive mattress can provide a sense of freedom and ease for those who like to move around or shift positions frequently. On the other hand, some mattresses are designed to contour to your body’s shape, providing a snug and cradling sensation. This contouring effect is often favored by individuals who seek pressure relief, especially side sleepers.
We thoroughly assess the firmness and feel of a mattress to provide personalized recommendations, guiding you toward the ideal choice for your sleep position while also highlighting who might find it less suitable.

Evaluating Mattress Performance
While your sleep position undoubtedly plays a critical role in determining the best mattress for you, it’s essential to understand that it’s not the sole factor at play. There are other key considerations to keep in mind as well. For instance, if you’re someone who tends to sleep hot, the mattress’s cooling properties become a vital concern. Similarly, if you share your bed with a partner, factors like motion isolation and edge support take on heightened significance in determining whether a mattress is the perfect match for your needs.
Cooling: Maintaining the Ideal Sleep Temperature
Quality sleep goes beyond mattress comfort; it’s about staying cool throughout the night. This is where our in-home testing truly shines. We spend several nights with the product, giving us a unique opportunity to assess the mattress’s ability to dissipate heat, its breathability, and moisture-wicking properties. We also dive into any unique cooling technologies the mattress may feature. The key questions we ask are: “Did we wake up sweating?” “Did we need to rely on a fan for comfort?” and “Were we consistently cool and comfortable throughout the night?” We evaluate all these aspects to help you make an informed choice for a comfortable and cool night’s sleep.
Motion Isolation: The Key to Undisturbed Sleep
Motion isolation is a mattress’s ability to prevent the transfer of motion, ensuring that your partner’s movements won’t disturb your sleep. At ASL Reviews, we prioritize motion isolation in our testing because it’s crucial for couples, light sleepers, and anyone who values undisturbed rest. Good motion isolation is your ticket to a peaceful night’s sleep, and we’re here to help you find the best mattress for it.
We evaluate motion isolation by actually sleeping on the mattress, replicating everyday scenarios like turning in bed or getting up. Our goal is to assess whether the mattress can effectively prevent our partner’s movements from disrupting our sleep. We want to ensure that your sleep remains undisturbed, whether you’re a light sleeper or a parent sharing a bed with a child.
Edge Support: Maximizing Mattress Space
Edge support is the mattress’s ability to maintain stability and comfort near its perimeter. It’s crucial for accessibility and stability.
In our evaluation of edge support, we perform two key tests: sitting on the edge of the bed and lying along the edge. If the mattress collapses or excessively sinks during these tests, it’s a clear sign of suboptimal edge support. This aspect is particularly significant for couples who share a bed. Inadequate edge support can make the mattress feel smaller than its stated dimensions, limiting your ability to utilize the entire sleep surface comfortably. Conversely, robust edge support is a reliable indicator of a bed well-suited for couples, providing ample space and stability for a restful night’s sleep.

Ease of Movement: Vital for Combination Sleepers
Ease of movement refers to how easily you can shift positions or get in and out of bed. A mattress that excels in this aspect ensures a comfortable, undisturbed night’s sleep. It’s not only vital for combination sleepers who change positions frequently throughout the night but also enhances overall comfort and convenience for those who use their bed for activities beyond sleep, such as reading or working.
To assess ease of movement, we fully immerse ourselves in the sleep experience. We don’t merely spend moments on the mattress; we spend entire nights on it, naturally shifting and changing positions. This hands-on approach grants us firsthand experience and insight into the ease or difficulty of moving around, as well as any potential sluggishness that may impact our night’s rest. If movement is effortless, it’s a positive indicator that the mattress could be an excellent choice for combination sleepers.
Materials and Construction: Unraveling the Comfort Code
When it comes to mattress selection, the materials and construction of a bed play a central role in defining your sleep experience. At ASL Reviews, we delve into the diverse world of mattress materials to help you understand how they can enhance your rest and to guide you toward the ideal choice.
Understanding Different Mattress Materials
Mattresses come in various materials, each offering distinct advantages:
- Memory Foam: Known for its slow-moving response time and deep contouring, memory foam is a popular choice for individuals with chronic pain conditions like fibromyalgia and arthritis. It cradles the body, providing exceptional pressure relief and support where it’s needed most.
- Latex: Latex mattresses are prized for their natural resilience and hypoallergenic properties. They offer a balance of support and cushioning, making them suitable for a wide range of sleepers, including those with allergies.
- Hybrid: Hybrid mattresses combine multiple materials, such as memory foam and innerspring coils. This combination provides the best of both worlds, making them an excellent choice for those seeking a balance between support, comfort, and durability.
- Adjustable Air Beds: These mattresses allow you to customize the firmness level according to your preference. They are particularly advantageous for couples with different firmness preferences, as each side can be adjusted independently.


Eco-Friendliness and Sustainability: Making a Green Choice
For the eco-conscious shopper, the materials and construction of a mattress also offer an opportunity to make an environmentally responsible choice. At ASL Reviews, we consider a range of factors that signal a mattress’s eco-friendliness, sustainability, and commitment to green practices. Here’s what we look for:
- Eco-Friendly Materials: We assess whether the materials used in the mattress are environmentally friendly. Natural and organic materials, such as organic cotton and natural latex, are often preferred by eco-conscious shoppers.
- Manufacturing Processes: We investigate the manufacturing processes used in the production of the mattress. Sustainable practices, reduced emissions, and minimal waste are indicators of a commitment to eco-friendliness.
- Certifications: We pay attention to certifications such as OEKO-TEX Standard 100, CertiPUR-US, and Global Organic Textile Standard (GOTS). These certifications signal that the mattress meets specific environmental and safety standards.
As sustainability becomes a paramount concern, we evaluate these eco-friendly signals in our mattress reviews to assist you in making a healthy, safe choice for your home.
