I have a simmons black pocket coil that I have had for about a year.  We decided to go with the plush top instead of a pillow because we figured the pillow top would degrade fast.  I have found though that I need more softness as my shoulder hurts in the morning due to being a side sleeper.  Other then that I love the bed.  My question is what kind of topper would anyone reccomend and what thickness is reasonable to make a difference.
