Hi AnalogJ,
I couldn’t agree with this more (as you know from the tutorial post which talks more about the two basic functions of a mattress) and I think that half the battle with shopping for a new mattress (and testing mattresses) is differentiating comfort/pressure relief from support/alignment. If anything alignment is a more important factor than “comfort” since the comfort can be adjusted if a mattress is too firm.
Point elasticity and the ability to contour to the body shape is certainly one of the “strengths” of pocket coils compared to other types of innersprings and is one of the reasons they are so popular.
As you may know from reading the site … I’m a fan of component designs that can be customized to the individual needs and preferences of different sleepers on a mattress both side to side and top to bottom. While the Niu is in a higher budget range than other types of component mattresses that also use similar high quality materials … the most important part of the “value” of a mattress purchase is always PPP (see post #13 here). How well you sleep on a mattress (suitability) and how long you sleep well on a mattress (durability) are the two most important parts of a successful purchase and if the Niu is in a budget range that someone is comfortable with and it’s the best choice out of all your finalists based on the parts of your personal value equation that are most important to you then it would certainly be well worth purchasing although I would always make some careful value comparisons when you are in a budget range that is higher than the norm.
Whether the Niu is a “better” long term purchase is a question that can only be answered in retrospect (how well you sleep on a mattress and how long you sleep well relative to the price you paid) so this is something that only you can answer based on your testing and “best judgement” and the criteria that are most important to you. I know that there have been some issues with some of the latex that comes from Latex International over recent years but for what it’s worth they appear to be “over the hump” (and hopefully this will continue with their chapter 11 bankruptcy which should remove some of the financial pressures) and there have been many fewer reports of issues that I have heard about in the last few months. There are also other component innerspring/latex mattresses that may also be worth considering either locally or online although latex/innerspring component designs are less common (two examples are Bay Bed & Mattress and Berkeley Ergonomics). I think that the closest dealer for BE would probably be Fly By Night if you wanted to test them in person (they use Radium Talalay).
This is part of the reason that I think highly of them as well.
I don’t know all the specific mattresses that are available to you locally and I don’t have any specific advice other than to continue doing what you are doing and following the steps in the tutorial post until you believe that you have done “enough” research and are ready to make a final choice. Based on the care you are taking and the thought you are putting into this and of course the research you are doing I think you will certainly end up choosing between some great options
