Several report seven to ten years of comfortable sleep; a few developed sagging or back pain later.
Owners who love the comfort and relief from aches are matched by others reporting sagging in the middle, showing up within weeks to a few years.
Flippable, so owners pick a firmness side; sagging or hip sinkage over time is the main downside.
