Hi levander,
I think you are bringing up a very good point. Sometimes it’s interesting to me how several posters at the same time touch on similar topics and my last reply in post #68 here just before this one would be appropriate here as well.
Quality of sleep and any “symptoms” that people experience either when they go to bed, during the night, or when they wake up in the morning can have many causes and only one of these is the mattress we sleep on.
Of course a mattress can have a significant effect on how we sleep and making sure that the one we choose provides good sleeping posture, pressure relief, microclimate control (temperature, humidity, and ventilation next to the body), and the ability to both change positions easily and to isolate movement from a sleeping partner can all be important to different degrees for different people but as you touched on there are many other elements to sleep quality and sleeping “symptoms” that have nothing to do with a mattress and there can sometimes be a tendency to think of a mattress as a “cure all” for sleeping issues which if course it isn’t.
It can be tricky to isolate the root cause of some symptoms because it can be easy to make incorrect assumptions about where they may be coming from but as you mentioned it is well worth exploring other alternatives to any sleep issues besides just the sleeping surface that we use.
Thanks for taking the time to share your thoughts and touching on one of the other parts of sleep quality that can be just as important as a mattress that we choose.
