Construction evidenceComponents documented; layer order not established

The reviewed sources name 2 components for Saatva Bunk & Trundle Mattress · Medium-Firm · 6", but do not support one reliable top-to-bottom sequence. No cut-open layer stack is shown because that would imply evidence we do not have.

Scope before conclusions

This page covers the exact database record “Saatva Bunk & Trundle Mattress — Medium-Firm — 6".” Earlier official materials described this mattress as 6 inches and Medium-Firm. The current product is 7 inches and Medium; the transition date and whether construction changed were not verified. Current-family specifications and performance are not silently transferred to this historical or retailer record. Nappedia has not slept on, opened, or laboratory-tested this mattress.
