In replacing my 20 year old mattress, I embarked on my usual exhaustive research. Early on I ran across a reference to bedinabox.com which sound like the Holy Grail of mattresses for a price I could afford. I did not find too many sites that have reviewed this company or their product except for 128 glowing posts on eopinions. All posts where from new users that had not posted before. So that looked a little odd, but ever stranger is that I can not find these posts by going directly to eopinions and searching. They only come up in a google search.

Would a company to go such lengths to sign up that many accounts to post 128 opinions? Seems like they would have at least spread it around more of the other sites.

Any ideas here? This search is about as painful as my old mattress. (I did find a few posts here that are legit - thanks for posting those)

Sure they'd do that.  It is done all the time in politics.  A very influential tool.  Does sound suspicious.
