Hi ShopperGirl,
I’m sorry to hear about your issues as well.
Outside of dn’s great suggestions once again … I would add my vote that you go very slowly and take things one step at a time. A day or two is not nearly enough to really make any major decisions. You have many options before taking more radical steps or adding to your costs. Don’t forget that the mattress you have is a very high quality choice so the goal is to find a way to fine tune it so that your PPP (Posture and alignment, Pressure relief, and Personal preferences) is just as good as its quality. If you sell the mattress your expenses/losses will be much greater than if you are successful in fine tuning it to your specific needs and preferences.
The first place I would start is post #2 here which can help you eliminate any of the other variables (including the initial break in period and the adjustment period that is part of every new mattress purchase, any toppers or mattress protectors you are using, and the effect of the quilted cover). Your mattress will change it’s “feel” over the first 30 days or so as materials soften a bit and the cover stretches.
This is part of the nature of natural latex and in most cases the ILD variation will be outside the range of perception but for some that are more sensitive it can make a difference. I would also find out whether the mattress you tested in the store was using Talalay latex made by latex international because they have recently changed to Radium Talalay which may also make a difference (the ILD’s between each may not be directly comparable).
A featherbed will have its own surface softness but is also less resilient and elastic than latex and may interfere with the ability of the latex below it to contour to your body shape. It can add some softness in terms of “feel” but may also add some firmness in terms of pressure relief. You can read more about the different types of softness in post #15 here. keep in mind that softness is very subjective.
Like dn … I also believe that changing a layer can make a significant difference and one of the benefits of your Savvy Rest is that you can exchange a layer. It would certainly be worth trying this before selling the mattress IMO. His advice here …
… is exactly the process I would follow … one step at a time. The initial purchase of a component mattress is just one step in the process.
But the first step would be to follow the suggestions in the first post I linked so that at least you have more clarity about the types of changes that would be most beneficial to you. One day is just not enough to evaluate your mattress and you have too many remaining options available to make quick decisions that can cost you a great deal of money IMO.
