Cheaper Serta sagging a few months after the trial ended

Published 12 January 2026: a reader writes that a less expensive Serta, bought against prior advice, now sags badly in the sleep spots after only a few months, after the trial, causing back pain. Custom platform frame described as sturdy. Cited as a dated letter, not a court finding. Cited next to this Storini file because the public pattern — sag after trial — is the context Serta already lives in. This is not a claim that the Hong Kong mattress is the same SKU. It is a claim that silence is not unique, and that published warranty and service sentences already exist for Serta to use if it wanted to answer.
