Pillow Research Methodology: How Pillows Are Tested

When considering sleep quality, people often focus solely on their mattresses, overlooking the equally important role of pillows. At Sleepiverse, we know a good pillow can make a big difference in how well you sleep. That's why we've created a thorough way to research and test pillows.

In this article, we'll delve into one aspect of our research methodology: pillow testing. By understanding our testing criteria, you can trust that our pillow reviews are unbiased and based on objective results.

The Importance of Choosing a Good Pillow

Choosing a high-quality pillow is crucial, but comparing numerous options and finding one that aligns with your preferences and budget can be overwhelming.

Our comprehensive pillow research methodology ensures that our reviews can be trusted to guide your purchase. A suitable pillow is essential for the several reasons discussed below.

Impact on Sleep Quality

A good pillow can significantly enhance your sleep quality by providing the support needed for a deeper, more restorative sleep. If you've experienced discomfort or poor sleep due to an unsuitable pillow, the right pillow can make a positive impact. Let's explore some of the benefits:

• Proper Spinal Alignment: A good pillow supports your head and neck, keeping your spine in the right position all night. This natural posture helps your muscles relax and ease strain.
• Reduced Pain and Discomfort: The right pillow significantly reduces neck, shoulder, and back discomfort, allowing you to start your day pain-free and energized.
• Prevention of Health Issues: Using the right pillow for a long time can help stop ongoing issues like sleep apnea or snoring, which boosts your overall health.
• Better Sleep Patterns: A comfortable pillow minimizes tossing and turning, leading to fewer disruptions and more consistent, quality rest.

Addressing Diverse Sleep Needs

When purchasing a pillow, consider your preferred materials and be clear about your specific needs. There's no one-size-fits-all pillow, so consider the following diverse sleep needs we highlight in our pillow reviews.

• Sleeping Position: Your preferred sleeping position can influence your ideal pillow choice. Side sleepers need a thicker pillow to keep their spine straight. Back sleepers do well with a medium-firm pillow to keep their neck comfy. Stomach sleepers should go for a thin, soft pillow to avoid hurting their neck.
• Preferred Firmness: How firm you like your pillow is up to you, but there are some tips to help you choose. It's key to know what you like and to feel the pillow yourself. We'll talk more about pillow firmness in the next section.
• Allergies: If you have allergies, choose pillows filled with hypoallergenic materials like memory foam or latex, and opt for those that are easily washable and maintainable.
• Temperature Preference: Consider your needs. If you want to stay cool, pick pillows made of bamboo or cotton. If you need warmth, choose down or synthetic down pillows.
• Size and Type: Pillow size and pillow type have a big impact on how well you sleep. Special shapes like pregnancy pillows, pillows for neck pain (such as contoured or wedge types), and other unique designs are made to meet specific needs.

How We Test Pillows

To test pillows, we've developed a comprehensive pillow research methodology to ensure we provide accurate and helpful recommendations for various sleep needs and preferences.

Our testing process involves multiple tests and assessments of various pillow characteristics, listed below, to help you visualize and predict how well a pillow suits your needs.

Unboxing

Packaging and unboxing are important factors to consider when purchasing any product, including pillows. A well-packaged product ensures safe delivery. For pillows, unboxing is crucial to understand if it arrives compressed or flat-packed.

In our pillow reviews, we break down the unpacking step by step, including any extra tips or instructions from the manufacturer to make it easy for you.

Besides opening the box, we give details on how long it takes to expand, if it's compressed, what the pillow looks like after it's expanded, and if there's any chemical smell, or off-gassing, which can happen with pillows made from low-quality materials. All this info helps you know what to expect when your pillow shows up.

Firmness

Pillows, much like mattresses, come in varying degrees of firmness. Pillow firmness describes how "hard" or "soft" a pillow feels when you rest your head on it. We gauge firmness with a standard scale, which measures how much weight causes the pillow to compress.

Our reviewers, representing different body types and sleep positions, test each pillow to ensure a broad assessment of firmness levels. We categorize pillows from very soft to very firm based on their ability to maintain an even surface and resist compression.

Pillow Shape and Loft

A pillow's uniqueness lies in its shape, with different shapes having an impact on various uses. We aim to describe the shape, point out the best sleepers for it, and show a picture. We also look at how the pillow's shape affects support and comfort for different sleep positions.

Pillow loft means how thick a pillow is when it's not compressed down, usually less than 10 inches. We make sure to explain this and identify which sleepers will get the most benefit from it.

Feel and Comfort

Pillow feel and comfort is highly personal. What feels comfortable to one person may not be ideal for another. For example, someone with neck pain might require a specific type of pillow, while another person simply wants a hotel-like feel.

Our reviewers test pillows by sleeping on them in different positions to check their support and how they mold to the body. We look at how well the pillow keeps the spine straight and eases pressure on certain body parts. We also give an honest take on how comfy the pillow feels overall.

Shape Retention

Pillow shape retention means how well a pillow keeps its form over time, especially when you sleep on it. A lot of pillows end up with dips or sagging spots where your head rests, and you need to fluff them up or give them time to bounce back to their original shape.

It is important to note that long-term pillow shape retention isn’t always immediately apparent and may diminish over time. Because of this, our team tests a pillow’s shape retention by sleeping on each pillow and assessing its initial performance. We then assign the pillow an initial score based on our initial impressions and continue updating our reviews as the pillow is used over time.

Moldability

A good pillow should balance shape retention, support, and moldability. Moldability refers to a pillow's ability to conform to the sleeper's head shape. A pillow with good moldability offers several benefits for sleep quality, including improved spinal alignment. Our reviewers test this aspect by lying on the pillow to determine which sleeper types are best suited for each pillow.

Responsiveness

Pillow responsiveness is not the same as mattress responsiveness. It shows how well a pillow supports your head during sleep. A pillow with high responsiveness makes you feel like you're "on" it, while one with low responsiveness gives the sensation of being "in" it. This comes down to what you like and need.

To test a pillow’s responsiveness, we perform 2 tests. The first is by pressing firmly on the pillow and observing how quickly it bounces back. The second test requires a reviewer to lie on the pillow, shift positions, and roll around. We then gather feedback on how responsive the pillow felt from the reviewer, whether it was easy to shift positions or if it created a dip that made it uncomfortable to sleep.

Cooling and Breathability

Pillow cooling and breathability are important factors for many sleepers, especially those who tend to get hot. To check this, our reviewers take a 20-minute nap on each pillow. During this test, the reviewer sleeps on the pillow in a room with a comfortable temperature and looks for signs of heat buildup or sweat marks.

Ease of Maintenance

Even when a pillow checks all the boxes we've talked about, you need to think about how easy it is to take care of. This includes things like finding pillowcases that fit, whether you can toss them in the washing machine, and if it has covers, you can take them off. When a pillow is easy to maintain, it works better, lasts longer, and is a breeze to clean.

Conclusion

Choosing the right pillow is key to better sleep and overall health. We've found that factors like your sleep position and personal preferences all play a role in finding the best pillow for you.

Our comprehensive pillow research methodology aims to help you find the perfect pillow for a good night's sleep. We look at different types of pillows, how they're made, and what makes them comfortable. Our testing process covers everything from how firm a pillow is to how well it keeps you cool, giving you a full picture of what to expect.
