Hi SleepTight,
Congratulations on your new mattress!
You certainly made a good quality/value choice (and hopefully you let them know you are a member here so you also receive your free shredded latex pillow).
I also agree that reviews can have some value overall … particularly about the legitimacy, knowledge, and service of the merchant … but I’ve also seen mattresses that have over 10,000 reviews or feedback on ebay and other places which are 99% positive for mattresses that I would never consider and are basically “junk” or “throwaway mattresses” based on the quality of the materials inside them. Some of my thoughts about reviews in general are in post #4 here.
Reviews that are about the merchant’s service or that include information about the quality of the materials or that would be of more general interest for more educated consumers (for example that included their height and weight information and the details about why they chose a certain layering) can be very valuable but in most cases they are written by people who praise (or condemn) a mattress who really don’t know what makes a good quality or poor quality mattress or what makes any particular mattress suitable for a specific person.
Having said all that … I’m looking forward to your review once you’ve received it and had a chance to test it out
