This is an important question, as the mattress industry is notorious for its non-transparent practices. Much like you are doing right now, we scour the web for non-biased user reviews and ratings. We search for feedback on online forums and message boards. Additionally, there are some legitimate mattress review sites and message boards where people have provided honest feedback.
Unfortunately, no mattress reviewer can give 100% personal feedback for every mattress. Even if given the opportunity to test a mattress, they obviously will be unable to opine regarding durability, warranty process, and even customer service with the manufacturers and retailers.
It is also important to note that it is nearly impossible to compare apples to apples on mattresses. Most retailers use their own brand name on mattresses they get from the manufacturers. So even though two people may have the exact same mattress, they wouldn’t even know it as they are marketed and sold as different products.
Additionally, many mattress manufacturers are not generous with information regarding the specs of their mattresses. If we could say this mattress has this many coils, this thick of a memory foam layer etc then it would be easy to say Mattress A is definitely better than Mattress B.
This is why we are here! We do our best to summarize class equivalent mattress lines so that you can have the information you need to make the best purchase for your household.
