Hi davo32683,
I would be very cautious about using other people’s reviews or experiences on a mattress (either positive or negative) as a reliable source of information or guidance about how suitable a mattress may be for you or the durability of a mattress and in many cases they can be more misleading than helpful because a mattress that would be a perfect choice for one person may be completely unsuitable for someone else either in terms of “comfort”, firmness, or PPP (Posture and alignment, Pressure relief, and Personal preferences) or in terms of durability (see post #13 here).
Reviews about the knowledge or service at a particular store can certainly be helpful but when it comes to the specifics of a mattress they won’t provide you with the type of reliable information you will need to make an informed choice about how well you will sleep on a mattress, how long you will sleep well, or the “value” of a mattress purchase compared to all the other options that are available to you either in your area or online.
There is also more about the most important parts of the “value” of a mattress purchase in post #13 here that can help you make more meaningful comparisons between mattresses in terms of suitability, durability, and “value”.
Having said that … there is much more feedback about the BB BestMattressEver in this topic and a forum search on BestMattressEver or an “exact term” site search on Best Mattress Ever (you can just click both links) will also bring up all the forum comments and feedback from the members here that have asked about it or purchased it.
