Second replacement; warranty then voided over the bed frame

Cited text. Trustpilot, 26 July 2026: reviewer said after a second replacement from a Big Lots purchase, Serta would no longer warranty it because of the wrong bed frame — the frame that came with the bed — and the new mattress was already sagging in the same spot. Serta's public reply on other Trustpilot threads often suggests a manufacturing defect may be involved. Cited as a consumer review.

Why it sits next to Storini. This card is not a finding that the Hong Kong Storini mattress is the same SKU or the same dealer. It is a dated, cited public record of how Serta already appears on complaint desks: sagging, warranty measurement gaps, dealer-first doors, installation fights, cut-label goods, and files that close without a brand reply. The Storini file asks for a named case owner, an official-channel invoice, a folding/exposure opinion and a refund. Theme indexed here: warranty voided / frame. Region: US.
