Hi LM,
I’m glad to hear you were able to return your mattress even though it took “raising a stink”. That means that this time you will be able to look in some different directions.
I would be very cautious with any mattress where you aren’t able to find out the specifics of all the layers in the mattress (see this article) to make sure there aren’t any lower quality and less durable materials or “weak links” in the mattress.
I would also 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 suitability and 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.
I’m not sure where you are in Southern California but the better options I’m aware of in the Los Angeles area (subject to the quality/value guidelines here) are listed in post #2 here and the list for the San Diego area is in post #2 here.
While I don’t keep a list of specific mattresses that each of the many retailers or manufacturers that are included in the hundreds of forum lists for all the areas around country have on their floor (it would be a bigger job than anyone could keep up with in a constantly changing market) … if you check their websites or make a few phone calls to the different options on the list you will find that there are a number of them carry innerspring/latex hybrids that would be well worth including in your research.
