Owners mostly like it, especially heavier sleepers and those wanting back support, and several report it holding up for years.
Owners disagree on feel, with some calling it very firm and others softer than expected.
Flippable, so owners pick a firmness side; sagging or hip sinkage over time is the main downside.
