Hi dmartin1910,
As you can see in post #13 here I don’t pay a lot of attention to mattress reviews. Reviews about the service of the company are more valid but in many cases the ones I read about OMF were customers complaining about the policies of OMF which they agreed to when they purchased the mattress (such as no returns). It’s fairly common that customers blame a company for making a poor mattress choice. Overall … OMF mattresses have had among the highest consumer ratings of the manufacturers that were included in the last two consumers reports surveys and their stores had among the highest customer service ratings as well so from a review point of view they are among the best of the more recognizable manufacturers although I take this with a grain of salt because once again … consumer reviews for mattresses (good or bad) are among the least effective ways to choose a mattress.
I don’t think that reviews like this are particularly credible. What has probably happened is that someone has chosen a mattress that was too soft in the first place and when the mattress was broken in it became a little softer yet and they ended up with back pain or other discomfort. It’s unlikely that the mattress was actually sagging (especially after a month) and this was most likely the result of a poor purchase decision.
OMF’s warranty has 1.5" and the other typical exclusions which are standard for the industry so I’m not sure what you mean when you say it is worse than what is typical.
Some of the better options and possibilities I’m aware of in the Atlanta area are listed in post #2 here.
