Hi Nene1957,
I certainly hope that this site affects sales since one of the goals of the site is to help change the industry by helping consumers understand how to make better quality/value purchases based on more objective information rather than marketing information (or hype) and to help “connect” them to sources of better quality/value mattresses that they may not otherwise know about.
Saatva is an example where the quality of their mattress doesn’t match their service or their customer reviews (which they “manage” very carefully) and Select foam is an example of the opposite where they sell a very high quality/value mattress but unfortunately their after sales customer service has a lot of room for improvement.
Some of the information in this topic may be helpful.
