Localized lumbar components are not separately visible. This is not a teardown or physical inspection by Nappedia.
Scope before conclusions

This research page covers the current U.S. The DUX 60 complete bed system. It is not a mattress-only product, and it is not merged with another DUX model merely because sizes or top-pad options overlap. DUX 6006 is retained as an official previous-name crosswalk, but the exact transition date was not found. Nappedia has not slept on, opened, or physically tested this system.

01

Editorial synthesis

Evidence behind the conclusion

Analysis

Traditional mattress-and-foundation complete bed system with three spring layers with pascal zoning in a separate mattress-and-foundation format; current exact-system independent testing was not found.

The DUX 60 is sold as a complete system, not just a loose mattress. Official sources establish the system identity, 9.5-inch base plus 8.75-inch top; 20.75 inches with comfort top pad, available U.S. sizes, and its core spring architecture. Traditional separate mattress-and-foundation architecture. Pascal zoning without the DUX 80 lumbar mechanism. Direct online terms are unusually restrictive: beds are final sale after delivery except under warranty, and store terms can differ. Public sources do not establish a complete materials ledger, a universal comfort result, or a current exact-model performance score.

Who the cited evidence may support

These are research signals, not a comfort guarantee.

  • Shoppers deliberately seeking a traditional mattress-and-foundation complete bed system rather than a conventional mattress-only product.
  • Traditional separate mattress-and-foundation architecture
  • Pascal zoning without the DUX 80 lumbar mechanism

What to check before choosing

These limitations may change whether the mattress fits.

  • No direct-sale comfort trial was located; delivered beds are non-returnable except as provided by warranty.
  • The 20.75-inch published profile is the combined mattress system with top pad, before chosen leg height
  • Historical owner/reviewer evidence is not a current controlled test
  • Generic DUX Bed owner reports do not identify this exact current system reliably enough to create a model score.
Confidence statement

High confidence in current identity, system type, published dimensions, broad spring architecture, online sale terms, and spring warranty; moderate confidence in the historical-name relationship; low confidence in exact-current independent performance because no configuration-matched test was located.

Analysis

DUX 6006 historical context

Editorial synthesis

An older independent review reports responsive support, robust edges, some noise, and owner-reported six-to-seven-year comfort life for the DUX 6006; it is historical, non-laboratory context and must not be presented as a current-system guarantee.

The publisher's older model label is kept visible. Its observations are not transferred to a current production lot or used as Nappedia's own rating.3, 7

No exact sample table is shown. A version-matched independent measurement set was not located for this mattress. Related family reviews remain in the sources used without being presented as tests of this mattress.
