I would tend to take this one step at a time. If your box spring is really a box spring and is not rigid (flexes with firm pressure) … then the first thing I would do is buy a firm slatted or wire grid foundation for your mattress to replace the box spring and the 1/8" engineered wood. IMO … this by itself could be causing problems as it is unlikely that it is firm or rigid enough for a latex mattress and your weight. I think this would be essential and then I would evaluate the results before considering any other changes. With the bed beam support it sounds like your Ikea bed is OK.
A few other comments … because I’m getting the sense that the mattress itself may not be as much of an issue as some of the other factors I mentioned in the previous post.
This is the next thing I would consider. Your pillow can make a significant contribution to upper body pain expecially and it may be either too thin and non supportive for side sleeping or too thick for stomach sleeping. Both of these could easily cause shoulder and upper back issues.
[quote]What I did in October:
I talked to Shaun at SleepEZ and he had me remove each layer from the cover and lay it flat on the floor to look for a 1/4 inch or more depression. Well, I could not see a 1/4 inch depression and not sure how I would detect such a thing. I did put each layer on my dining room laminate floor and I both looked at each later and I walked around on each later. The only one that had something odd about it was the medium later which MAY HAVE felt like it was a little less dense under foot, near seam about 1/3 of the way in from the short edge.[/quote]
While I doubt this would be an issue … you can run a string from one side of the mattress to another which will give you a better idea if there are any significant dips. There are normal variations in density in latex but it would be very difficult to tell with the sensitivity of foot pressure. These normal variations (assuming they are within the range of normal) would not be having the effects you are seeing.
[quote]When I reassembled the bed, I put the firm layer back as it was before, rotated AND flipped the medium layer, and I rotated the soft layer. I also removed the bed frame and put the box spring, topped by the 1/8 wood and then the mattress right onto the floor. I feel like I’m back in college.
My lower back slowly got less fatigued between OCT and JAN. Now my back is starting to feel fatigued again.[/quote]
Again … the first thing I would suspect here (besides other influences) is the box spring and engineered wood.
Since 9/2009, I have been at a new job that has me driving 10 hours/week on top of having to replace my mattress and completely giving up exercise. I also have some medical things going on that are so far minor, but are neurological, so who the heck knows. But it seems to me that the mattress could be the culprit, since I didn’t have this sort of pain until after I purchased the new one. I am wondering if the mattress may be just a bit too firm for me and if I add a topper it could help. [/quote]
From your descriptions, it seems to me the “cause” of your issues may have more to do with changes in lifestyle or “accessory issues” connected with the pillow and base than with the mattress itself although a mattress can certainly affect things that you would otherwise experience either more or less. I know it’s easy to make connections but you were using the same mattress when things improved as well as when they got worse so that improves the odds that it would be wise to first look elsewhere.
I would also doubt that your mattress is too firm. If I had to guess it’s more likely that with increased weight and the tendency for stomach sleeping … the middle or lower layers may need to be firmer. The boxspring has the highest odds of being the “culprit” with the back issues and the pillow has the highest odds of being the culprit with the shoulder issues (outside of lifestyle etc) and I would start with these. Your stomach sleeping will also play a major role and I would consider having a second pillow at hand that as much as possible you can put under your pelvis when you move onto your stomach. If your memory foam pillow is thick and supportive enough for your back … then it’s also likely that it’s too thick for your stomach sleeping and you may need a pillow that can adjust itself better for both positions (something that can be scrunched up to make it thicker or be used as a thin layer such as down or buckwheat hulls). It would also be well worth seeing if you are able to move away from stomach sleeping at all which can cause or aggravate many back and muscle issues … particularly in combination with side sleeping.
There is some good information here in connection with back issues which I found particularly accurate and helpful. The links on posture and mattresses may be especially helpful although the other links are also very informative.
I would start though with the foundation and the pillow to see if they may help to the degree possible and then I would re-evaluate to see what changes in the mattress itself may also help. The fewer variables you are dealing with at a time the better.
