Hi Doulas,
Thanks for taking the time to share your experience … I appreciate it!
I switched your post to a new topic of its own so that it would be easier for others to find that are looking for feedback about SleepEZ rather than being mixed in with a more general topic.
As you know I think you certainly made a great quality/value choice … and congratulations on your new mattress 
It’s also great to see that you were able to find a layering combination that works well for you and the ability to rearrange or exchange layers after a purchase is one of the biggest advantages of a component mattress.
Occasional shoulder pain can often be a pillow issue and it may be worth trying a different pillow to see if it helps. There are also some suggestions in this topic that may be helpful as well.
