Hi khibbard,
I usually take all reviews with a grain of salt anyway (you can see more of my thoughts about reviews in post #13 here) but they are a marketing company that may often ask their customers to post a review so many “suspect” reviews that sound similar would not be unusual in cases like this.
I would always evaluate a mattress on the basis of it’s materials and layering using “apples to apples” comparisons with other similar mattresses rather than paying particular attention to reviews which are mostly written immediately after a sale by people who have little knowledge about the quality of the mattress they just purchased.
I have seen some ebay merchants for example that have over 10,000 positive ratings in the 99% positive area and yet almost none of these realized they were buying a “cheap” memory foam mattress with low quality materials that wasn’t worth any more than they paid for it … and yet they believed that it was comparable to higher priced mattresses … at least initially (when they wrote the review in the excitement of their initial belief in “the deal” they were getting).
These types of reviews that are often about the “deal” they believe they received or to justify a purchase and that seems to populate many online review sites are mostly meaningless anyway IMO because they usually are written soon after a purchase and don’t provide any meaningful or relevant information about the mattress or themselves.
