Sofa Manufacturing & Quality Guide
Density, recovery and inspection — read together or not at all.
How density and inspection decide your return rate
The sofa manufacturing process and quality control are the same question asked twice. Foam density decides how a sofa feels when it lands and how completely it recovers after compression — the working standard here is a 48–72 hour expansion back to full shape. Where density is too low, recovery is incomplete, the buyer reads it as a defect, and that is where returns and chargebacks begin. Inspection exists to catch it before the carton is sealed: every shipment is checked at 4 semi-finished stages and 3 packing stages, and first-pass yield stays above 98%.
