Hi smeagol108,
I’m not clear if you only sleep on your side or if you sleep in other positions as well or which sleeping position seems to be primarily responsible for which symptom.
If you could add more clarification about any connections you can see between your sleeping positions and the symptoms you are experiencing it would be helpful because some of them seem to be coming from when you are on your back (such as watching TV) and some may be coming from side sleeping (arms falling asleep). The first thing I would test though is a change in pillow so that your head and neck are better aligned in all your sleeping positions because in many cases upper body symptoms or even shoulder pressure issues can come from a pillow that is either too thin or too thick and it’s often the case that a different mattress needs a different pillow to better compensate for any differences in how much you are sinking in and the distance between your head and neck and the mattress in each sleeping position.
Testing the effect that different pillows have (on the layering that seems to be best for you which seems to be the 24 over the 32) would be the next thing I would try and either rule in or rule out.
There are some good sources for stretch knit unquilted covers in the component post here (they are also listed here).
Outside of a DIY design … SleepEZ and Arizona Premium would both be worth talking to about mattresses that have an unquilted knit cover.
