This is about asking if someone prefers "Blondes, Brunettes, or Redheads".
The only logical answer is "YES"!
Truthfully: you just have to find one that suits your back the best. There is no one correct answer.

We put a 4" topper (from Sam's) on our factory mattress and we love it. Me and the DW had some fun cutting the topper to fit.

Miramar Mike, If you are located near OC, go to Custom Comfort and take your pick of any mattress in the store and they will make one specific to the size you need. Prices range from around $700 on up depending on your needs. That is what we did and are very happy with the results.
