Hi Kristenebean04,
Welcome to the
Mattress Forum!

.
If you haven't read it yet ... the first place I would start your research is the
tutorial post here
which has all the basic information, steps, and guidelines that can help you with how to make the best possible choices ... and perhaps more importantly know how and why to avoid the worst ones.
I am a side sleeper about 128-130 pounds with big hips and a small waist. While searching, my main issue is mid section support. The small part (waist) before my hips start, dips down causing an alighment issue resulting in my pain. Either that or my hips are too high on the mattress which I'm assuming causes the same issue. I had the wrong idea and thought that the more comfort layer on top=not as supportive (which is why I thought this mattress was a good choice), but now I realize that is not true and I just need to find a correct amount. I'm assuming maybe it is because this particular innerspring isn't supportive enough? It does have a lot of give to it. I do realize that a lot of the traditional innerspring mattresses seem to give me better alignment. I do like foam beds, but worry about it breaking down soon, especially if the Tempur-Pedic did, and it is supposed to be a higher quality.
As you mentioned both a mattress that is too soft and a mattress that is too firm can cause support and alignment issues and like the three bears the goal is always to find a mattress that is not too soft and not too firm but is "just right" in terms of both support/alignment and comfort/pressure relief. Too much or too little of either one can mean a mattress that isn't a suitable choice in terms of PPP (Posture and alignment, Pressure relief, and Personal preferences).
I would tend to avoid "theory" though because it can take a long time to become an expert in mattress design and theory and the learning curve never really ends. The most effective approach is normally to use careful and objective testing (using the testing guidelines in the tutorial post) where your body can tell you which mattress is a good match for you along with the guidance of a knowledgeable and experienced retailer or manufacturer who already knows what you would otherwise need to learn.
Also, do you think you could help me figure out what type of comfort layer and support I would need for my body type? Should I give you my measurements? Am I gettting WAY too technical? Hahaha! Thanks in advance.
Unfortunately I can't feel what you feel or see you on a mattress and there are too many unknowns, variables, and preferences involved for anyone to use "theory at a distance" or specs (either yours or a mattress) to know which mattress may be best for you (see
mattress firmness/comfort levels in post #2 here
). Having said that ... outside of the links there if you are interested in some of the theory behind mattress design then
post #4 here
has more information about primary and secondary support/alignment and their relationship to comfort/pressure relief that may be interesting to you. There is also more in
post #6 here
that can help you visualize what good alignment "looks like".
The quality/durability of the materials in a mattress will also play the most important role in how long you will sleep well on a mattress and
post #4 here
and the posts it links to has more about the many variables that can affect the durability and useful life of a mattress relative to each person but it's also important to make sure that a mattress you choose isn't "on the edge" of being too soft for you when it's new because then only a very small amount of foam softening can take you "over the edge" and even a mattress that uses relatively good quality materials may not last you very long (see
post #2 here
).
I am from Oklahoma, close to the Oklahoma City area. I do know about Oklahoma Mattress Company. I went there a few times, but none of the latex beds he has to try seemed to give me the proper alighment. I did go back the other day and laid on 2 different mattress toppers stacked together and it seemed to be better. So, maybe I just need to play around with the different layering to get the right fit. Is there any other good quality local stores that would be good for me to try?
The better options and possibilities I'm aware of in the Oklahoma City (including Jim at Oklahoma Mattress) are listed in
