A sectional usually creaks because something is moving where it should not. This guide explains why your sectional keeps making frame creaks and what to check first. Common causes include loose frame joints, shifting sectional connectors, uneven floors, loose legs, or worn support under the cushions. The chaise and corner sections often make more noise because they carry extra pressure. Start by tightening the legs, reconnecting the modules, and checking whether the sofa rocks on the floor. If the frame feels weak or the noise gets worse, repair may be needed.
