Simply remove your cushions, unfold our sofa support board across the seat frame, and place your cushions back on top. No tools, no hardware, no hassle. Restore a firm, level seating surface instantly and stop that "falling into a hole" feeling for good. , 8MM THICK PANELS, BUILT TO STAY FLAT - Each panel is made from 8mm Poplar LVL engineered wood, moisture-controlled during manufacturing to resist warping, noticeably sturdier than thin cardboards or foam inserts sold as quick fixes. Our couch cushion replacement won't bow, bend, or compress under daily use. , ANTI-SKID FINISH KEEPS IT LOCKED IN PLACE - An anti-skid finish on the underside grips your sofa frame, keeping the couch cushion support insert from sliding or shifting once your cushions are back on. Rounded corners and beveled panel edges protect your upholstery from snags and won't dig into cushion fabric over time. , FOLDS FLAT, INSTALLS INVISIBLY - Every panel connects at a fold line so the whole heavy duty couch cushion support lies completely flat under your cushions instead of creating a lump, and folds compactly for easy handling and storage. Wrapped in 600D Oxford fabric coated on both sides, with overlocked seams for durability. No loose panels to align or reposition, just unfold and place. , MEASURE FOR THE BEST FIT - For best results, measure the inside width (arm to armand depth (front rail to back railof your sofa seat before ordering. Sofa frame dimensions vary by manufacturer, so measuring first helps you pick the right size for your couch or loveseat. Slight variance is easy to work around thanks to the foldable panel design. Works only with sofas that have removable seat cushions.
