Mattress Reviews 2021


Buying a Mattress Made Easy

Shopping for a mattress can be frustrating and time-consuming. Best Mattresses is here to help you cut through the confusing language and avoid the pitfalls of slick salespeople. Buying in a mattress store or department store furniture aisle can see you paying five to ten times more than you should.

The myriad of online mattress sellers (and more every day) offer great mattresses at competitive prices, delivered right to your door so you can try the bed in your home. A 5-minute lie down in a store won’t tell you how a mattress will perform for you night after night, year after year.

Best Mattresses has done the research, and our reviews are designed to help you choose the best bed for you from the top online bed sellers. Our thorough review process and in-depth analysis of every mattress we rate is for your benefit. See our rating methodology below to learn how we work for you.

Our Rating Methodology

Quality of Materials

What goes inside the bed determines how well it performs. We assess the density and quality of foams, construction of innerspring coils, and features of latex. In addition to examining the individual components of the bed, we look at the overall mattress design and how the materials work together to deliver a sleep experience. Best Mattresses reviews call special attention to organic, all-natural, sustainable, and high-tech materials that are on the cutting edge of mattress manufacturing.  


How long a mattress will last is a foremost concern for mattress shoppers. Before you sink your money into it, you need to understand lifespan, but many manufacturers online are very new. This means they don’t yet have a track record to assess historical durability. That’s why Best Mattresses carefully evaluates the quality of materials, and mattress design is so important. Quality materials in a thoughtfully architected bed is a good indicator of future durability.  

Support/Spinal Alignment

Support is different from firmness and refers to how well a bed keeps your spine in alignment while you sleep. The natural “s” curve of your spine should be maintained constantly whether you sleep on your stomach, back, or side. Choosing the proper support based on your preferences is critical to getting the sleep experience you need. Best Mattresses’s reviews consider how well a mattress supports based on a variety of factors including sleep posture and body weight, among others.  

Pressure Relief/Conforming Qualities

Comfort is subjective to each person, but key mattress attributes can be studied to determine what you can expect while sleeping on that bed. Your hips and shoulders are key points of pressure, particularly for side sleepers, and need adequate cushioning as provided by the upper comfort layer(s) of a mattress. How well a bed conforms helps ease pressure and encourage quality sleep. Materials quality, plushness, and construction of the comfort layer(s) are all part of our evaluation.  


How cool a bed sleeps is an essential deciding factor for many people when buying a mattress. As part of Best Mattresses’s review process, we consider materials that may contribute to hotter sleep including the manufacturing of foam, memory foam, and latex, wicking cover materials, and the overall design of the bed and how it prohibits or encourages airflow and heat dissipation. Most people sleep better on a cooler bed, and we also consider factors such as high-tech and moisture-wicking materials that help disperse heat.  

Motion Transfer

Motion transfer is the energy displaced when you move on your mattress. A well-made mattress should minimize or eliminate motion transfer so that as you and your sleep partner shift at night, the movement doesn’t transfer across the bed’s surface disturbing your sleep. Best Mattresses evaluates motion transfer and considers how the bed’s design, support core, and comfort layer(s) work together to prevent motion transfer, so you get a better night’s sleep.  


Mattress responsiveness is how quickly the bed adjusts to changes in pressure. A bed with a fast response time rapidly adapts to your movements as you shift in your sleep and (very importantly) during sex. A mattress with a slow response time doesn’t adapt quickly enough to your changing position. With a slow response time, you may feel “stuck” in the bed. Best Mattresses looks at response time as part of our review process, so you’ll know how the bed performs as you move.  

Edge Support

How much integrity the mattress maintains on its sides as you interact with it is called edge support. When you use the edge of your bed to get dressed, put on socks, tie your shoes, read, or for sexual activity, you want to know it will support you. Some materials (innerspring, firm latex) are better for edge support than others (foam and memory foam). Best Mattresses lets you know what to expect when you sit, lie, or bounce on the edge of a mattress you’re considering for purchase.  

Customer Service

A mattress maker can have a great product, but if they’re deficient in customer service, it can be a problem. As part of Best Mattresses’s review methodology, we look at the manufacturer’s track record with its customers, how they handle complaints, and how they rate with the Better Business Bureau, if applicable. You want to know that you’re getting a quality mattress but also, if there’s an issue, that you’ll get the consideration you deserve.  

Trial Period/Warranty

Sleep trials are often generous with online bed sellers ranging, on average, from 100 days up to years. Some manufacturers have a mandatory break-in period of a couple of weeks to a month before they’ll approve a return. Best Mattresses’s review tells you what to expect from the sleep trial, any applicable break-in period or other caveats. If the bed breaks down, the warranty is critical, and we’ll let you know what the maker’s guarantee covers, how long it lasts, and any fine print you should know.  

Social Impact

Many new manufacturers are committed to making a social impact with their business, reducing their carbon footprint, or giving back via philanthropy. While researching manufacturers and their products, we dig into their social impact and let you know if they donate to charities, whether they’re committed to lessening environmental impact, are sustainably sourcing materials, and other aspects of their business model that may be important to potential buyers.
