How We Test Mattresses
Here at Sleepopolis, we only recommend beds that we’ve tested personally. We’ve brought hundreds of mattresses to our lab, where our team of experts gathers to evaluate each by collecting and comparing 50-plus distinct data points.
Full Team of Experts
Our team is made up of Certified Sleep Science Coaches and industry experts with years of hands-on experience with mattresses and sleep products. Whenever possible, we have multiple people with different body types and comfort preferences evaluate a given bed. We also consult with a network of physicians, physical therapists, nurses, and other medical professionals to verify our findings and ensure we’re providing helpful, health-focused recommendations.
Purpose-Built Mattress Lab
We use specialized tools to collect readings on critical aspects of a bed’s performance— temperature, pressure relief, motion isolation, and more—in an environment designed for repeatable, reliable testing. These results are compared and contrasted with notes on how a mattress really feels and performs according to our in-house testers.
13 Data-Driven Tests
Each of our tests is scored individually and then combined on a weighted scale that determines a mattress’s overall rating, which is numbered from 1 to 5. All of these scores then inform our mattress recommendations for specific kinds of sleepers, such as dedicated side sleepers, people with sleep apnea, and folks who prefer a very firm bed.
The Core Tests Behind Every Review
Every mattress we review is put through the same 13-point set of comprehensive tests. Below are some of the most important ones that impact sleep quality and long-term comfort.
Firmness
Rated on a 1 to 10 scale, with 1 being the softest and 10 being the firmest.
Pressure Relief
Measured with a pressure-mapping mat to see how evenly weight is distributed.
Edge Support
Scored out of 5 based on sitting, lying near the edge, and weight-plate tests.
Cooling
Scored out of 5 with surface temperature readings taken by a thermal gun.
Motion Isolation
Scored out of 5 using water-ripple, partner, and rolling tests.
Responsiveness
Scored out of 5 using real tester feedback and a timed kettlebell snap-back test.

What is Sleep?
The pace and priorities of modern society have led many of us to believe that rest and downtime are optional. Work, family, and school schedules may seem to require more hours than exist in a day, often leading us to steal time from one of our most essential biological functions: sleep. Sleep is an altered […]
How Sleep Affects The Body
Sleep may appear to be as simple as feeling tired, lying down, and nodding off. But the physiological state of sleep is created by a complex interplay of processes in the brain and body, beginning with signals from the circadian rhythm’s master clock. While sleep originates in the brain, it is a body-wide experience that […]
Why Do We Sleep?
We all know how we feel when we sleep well, and when we don’t sleep enough. When we sleep, we’re happier, we have more energy, and learning comes more easily. When we don’t sleep, we feel unfocused, exhausted, and irritable. We can feel the effects of sleep on our brains and bodies, but we may […]
Sleep Stats & Facts
We may be out for the count and largely unaware of what’s happening around us while we sleep, but our bodies remain busy with myriad biological housekeeping functions. And while most people are well aware that sleep is a cornerstone of health and well-being, it seems that daily life in the 21st century, hustle culture, […]
The Genetics of Sleep
Sleep is a universal physiological drive with similar processes and rhythms across the human species. Though sleep follows a recognizable pattern, there are numerous differences among healthy individuals. Though some of these differences are environmental and relate to meal times, travel schedule, and work routine, many are inherited. Whether you’re an early bird, a night […]
Sleep Disorders: Typical Causes and Information
How much do we really need sleep? A lot, it turns out. Sleep rejuvenates our bodies and minds, gives our immune system a major boost, and repairs and builds tissues throughout the night. (1) Sounds pretty amazing, right? When sleep disorders steal your sleep, you can feel sluggish, cranky, and forgetful. We’re going to tell […]
Insomnia: Symptoms, Causes, and Treatments
Do you ever have trouble sleeping? At one time or another, most of us have experienced bothersome symptoms of insomnia: difficulty falling asleep, staying asleep, or both. We may have lived through bouts of insomnia that last a few days, or much longer. Though the symptoms may seem simple enough, insomnia is a complex condition […]
Sleep Disorders in Children
Most children hate sleep at certain points in their development — life feels too full of adventures, games, and delicious snacks to waste time sleeping! In J.M. Barrie’s Peter Pan, Wendy, Peter, and Michael’s canine nanny was trying to put them down for the night, but little Michael hollered, “I won’t go to bed!… I […]
Sleep Apnea And Memory Loss
Do you get punched at night for deafening snores? Or wake up feeling tired even though you think you got plenty of sleep? These signs could point towards sleep apnea, a common sleep disorder that affects millions of people worldwide. Sleep apnea not only disrupts your sleep but also affects your brain function and memory. […]
Types of Insomnia
Insomnia can steal just a few night’s sleep, or it can hang around for years. Over the decades, experts have categorized and re-categorized the different types of insomnia, and while all insomnias fall under three main umbrellas now, your specific insomnia may also be in a subcategory. Figuring out your own special blend of sleeplessness […]
How To Get Better Sleep
Sleep is essential for optimal well-being, and impacts everything from mood to muscle strength to memory. Despite the importance of adequate rest, many people don’t get consistent healthy sleep. Poor sleep can be associated with numerous physical and emotional factors, including stress, medications, medical conditions, and poor diet. The most common sleep difficulty in the […]
Magnesium vs. Melatonin
Melatonin as a mainstream sleep aid has long been accepted — promising sound, natural sleep, touted as a “miracle” for people with sleep disorders. But in recent years, magnesium has taken the spotlight, claiming that it promotes more restful sleep and improves sleep longevity with fewer negative side effects compared to melatonin. So does it […]

Sleep & Heart Health
We all need a heartbeat to survive, and quality sleep also plays a vital role in our overall health. But did you know sleep and heart health are connected? It’s true — how well you sleep through the night can have an impact on your cardiac function, and vice versa. (1) More than one third […]
Weight Loss and Sleep
So, you’re doing everything right to lose weight: meticulously counting calories and hitting the gym. Yet the scale won’t budge! Certain health conditions, genes, and even side effects of medications could be part of the problem. (5) But here’s something you might not have considered: your sleep habits could be sabotaging your weight loss efforts. […]
Exercise & Sleep
The solution to a more restful night? Movement, experts say. It seems the answer to so many physical and mental health woes have just one thing in common — exercise. Sleep is no exception. If you are looking for longer sleep, higher-quality sleep, or fewer interruptions from sleep apnea, insomnia, and other ailments, the type […]
Health Benefits of Sleep
We may all have our differences, but every human in the world needs sleep. Why is sleep important? Every system in your body relies on good sleep to recover from the day and get ready for the next one. (7) The benefits of sleep include better immune health, easier weight management, a healthier heart, improved […]
How To Sleep With Lower Back Pain
Picture it: You’ve just woken up after a horrendous night of sleep, your night of rest disrupted by the relentless nagging of lower back pain. Many of us can relay a similar story, whether your back pain is triggered by a longstanding problem or an acute injury that’s baring its teeth whenever you try to […]
Athletes And Sleep
Most of us are no stranger to the phrase “be sure to get a good night’s sleep” — especially the night before an event that requires us to be at our best, like an important presentation or test (1). Athletes of all levels are no exception: Getting adequate sleep pays off just as much in […]
Sleep Hygiene Guide
How well do you set yourself up for successful sleep? If you’ve never heard of sleep hygiene, the term might sound odd. But having good sleep hygiene has nothing to do with keeping you clean. Sleep hygiene describes lifestyle choices that promote quality sleep. When you know how to do it, you may notice you […]
Is 6 Hours of Sleep Enough?
While you may look forward to crawling into bed and getting some much-needed sleep, part of you may wish you needed less of this essential habit. How many people have dreamt of somehow having more hours in the day? Sometimes it may seem that the easiest way to add time to your life would be […]
What Are Dreams?
The mystery of dreams has captivated people for millennia. And while life in the 21st century (and the unprecedented access to information that comes with it) leaves us with relatively few mysteries, some questions remain. Take sleep and dreams, for example. With all we know about sleep, questions about the purpose and nature of dreams […]
