This organic (yeah!) mattress pad worked wonders to ease my hip pain from an old injury.  It is odorless and helps me sleep better on my old mattress. The only reason I didn't give it five stars is because there is one (soft) ridge of wool where it was folded. Even so,  I don't feel the fold in bed and expect that it will flatten over time or when the pad is first washed. This is a keeper!
