Husband and I have swapped sides in the bed for the last few nights and omg it makes a huge difference for me and I don't even know why!
He kissed me this morning and said "I don't think you moved all night" on my side I was tossing and turning all night long!
I do the same thing! I make my husband switch sides usually once every 4-5 months. And I honestly feel like because he is heavier than I am it compacts the pillow top so it isn't as soft...if that makes sense....and part of it is probably just in my head. @marileab
