Hi Nicoleski,
You’ve probably read it already but just in case you haven’t the first post in this topic has an analysis of the Saatva mattresses that may be helpful. In very general terms I would say that for most people it would be a “better than average” quality/value choice compared to most of the mainstream mattresses made by the major manufacturers but it wouldn’t be in the same “quality/value” range as many of the other options that most of the members here would know about as a result of the information on the site.
The first place to start your research is the mattress shopping tutorial here (it has a shorter and a longer version) which includes all the most important information, steps, and guidelines that can help you make the best possible choice … and know how and why to avoid the worst ones including the major brands and the chain stores that usually sell them or any mattress where you can’t find out the type and quality/durability of the materials inside it (see the guidelines here).
Two of the more important links in the tutorial that I would especially make sure you’ve read are post #2 here which has more about the different ways to buy a suitable mattress that is the best “match” for you in terms of PPP (Posture and alignment, Pressure relief, and Personal preferences) that can help you assess and minimize the risks involved in each of them and post #13 here which has more about the most important parts of the “value” of a mattress purchase which can help you make more meaningful comparisons between mattresses in terms of suitability, durability, and value.
