Why Trust Sleep Like The Dead's Mattress Reviews and Comparisons

Our mission is to help people make smart sleep-product buying decisions. This can only be achieved by providing unbiased, truthful, and hard-hitting information.

  Sleep Like The Dead Other Mattress Review Websites
Valid, Accurate Research Method yes no or questionable
Our mattress reviews / ratings are based on over 25,000 mattress owner experiences gathered from diverse, credible sources using a precise, unbiased methodology. Reviews / ratings are often based on the flawed methods of personal testing or the accepting of reviews from site visitors. And in other cases, the method used is vague and poorly described.
Revenue Source Encourages Bias very little usually very much
To provide our site with revenue, we use Google Adwords which automatically selects and places ads on our site. Adwords uses an auction to determine which advertisers / ads appear. This means we do not select who advertises on our site. This lack of direct financial relationship with mattress companies keeps incentive to be biased minimized.
Other mattress review websites often have direct financial relationships with mattress companies of their choosing as they receive revenue directly from them via referral programs. This arrangement causes much incentive to practice favoritism in regard to which mattresses are reviewed by the site and how favorably a particular mattress is reviewed.
Evidence of Bias no usually yes
To be unbiased means to 1) consider all relevant facts and 2) not ignore anything good or bad. Upon reading any of our mattress reviews, it's clear that this is our method. That we are unbiased is also shown by the fact that mattresses of non advertisers are our best rated or among our best rated mattresses. Other mattress review websites often reveal bias by providing "softball" reviews which consist of providing mattress pros but few if any real cons. This is often especially true for mattresses that the sites earn revenue from via referral links including the offering of discounts / coupons to site visitors. (See other signs that a mattress review website may be biased.)
Transparent Identity yes usually no
At Sleep Like The Dead, we are proud of what we do and have nothing to hide, to fear, or to feel guilty about. So we have no reason to conceal our identity. Most mattress review websites hide their true identity in some way. They may not provide anywhere on their site the full or real name of the person or people behind the site. And a WHOIS search often shows that the site owner keeps their name private and confidential.
Time in Operation 9 years
2 years median
We have been reviewing mattresses since 2008. Sleep Like The Dead is in many ways the "original mattress review website" in that much of the format, review criteria, and research findings used by other mattress review websites was originated by us. The median age of other mattress review websites is around two years. Most of these sites appear to have sprung up solely in response to the emergence of referral programs by mattress companies.
Mattress Research Findings in Credible Publications yes usually no
Our mattress research has been mentioned in The Wall Street Journal, US News and World Report, Barron's, Chicago Tribune, USA Today (The Best), St. Louis Post-Dispatch, Toronto Star among many others. Other mattress review websites tend to generate limited positive media coverage.
