Some of our articles feature comparisons or ratings of mattresses, and in case you were curious how we arrived at our conclusions, here is our process.
We typically collect our data from one or more of the following sources, specified within the article: owner reviews and experiences available on manufacturer websites, third party review websites, and forum discussions.Occasionally we may also conduct polls our surveys, which will be identified as such.
While owner reviews can be subject to bias, we assess each source for legitimacy, editing, or dishonest tampering to keep information as accurate as possible.
In aggregate comparisons, we look at the entirety of reviews available (from one or more of the above sources) to provide a general picture of a brand. While variance will exist among individual reviewers and beds, this can be helpful for gaining a general sense of how one brand may compare to another.
Some of our comparisons will also look at specific models, using only reviews for that specific bed. When comparing specific aspects such as longevity or durability, we may filter reviews to ensure accuracy by length of ownership or other factors as stated within the respective articles.
Graded Rating Process
To assign grades for comparisons, we generally look at the star rating for a specific aspect if available (out of 5), or divide the number of times an issue or benefit was mentioned by the total sample size to achieve a percentage and compare this with the general average for the mattress type.
A – 90%-100% or 4.0-5.0
B – 80%-89% or 3.0-3.9
C – 70%-79% or 2.0-2.9
D – 60%-69% or 1.0-1.9
F – 59% or less or 0.1-0.9
- If 92% say they would recommend a bed and average reviews give a rating of 4.3/5, than that bed would receive an A for owner satisfaction.
- If 75% said they would recommend a bed and average reviews gave an owner rating of 3.0/5, we would consider other important satisfaction measures (how many say comfortable for example) to see if the model should receive a C or B- rating.
- If 5% of reviewers complained of heat, that means 95% did not. If the collective average for that mattress type is 10%, than that bed would receive an A rating for heat. But, if 15% of reviewers complained of heat, making it worse than the average for that mattress type, the bed would receive a C.
