Corner Blocking — Verified Audits

Corner blocking is invisible but testable: lift a sofa slightly and apply gentle lateral pressure to each corner. A corner-blocked frame has zero flex; an unblocked frame shows slight racking (twisting) under the same force. Absence of corner blocking is the leading cause of frame joint failure in budget sofas within 3–5 years of use.
