Hi dxmichelle,
You certainly made a good choice and first of all … congratulations on your new mattress 
I’m looking forward to your feedback and comments when you receive it and have had the chance to sleep on it for a while.
You will find some good information and feedback about pillows in the pillow thread here.
There is also some good information and links to resources about different types of sheets and materials in post #7 here and post #26 here and some of the other posts and resources they link to as well
