In short

Owners mostly like it, especially heavier sleepers and those wanting back support, and several report it holding up for years.

Many report six to ten years of cool, comfortable sleep; some hit sagging after a few years.

Owners disagree on feel, with some calling it very firm and others softer than expected.
