About this item
- Add Strong, Long Lasting Support to Couches and Sofas: easily and quickly upgrade your sagging couch or sofa with our ultra-strong, high-quality plywood sofa cushion support board; adds extra support and comfort to couches with sagging frames, cushions, or worn-out springs; our sofa support boards are 21.5” wide to cover more surface area, providing more couch cushion support for sagging couch seats
- ULTRA DURABLE .43 INCH THICK PLYWOOD BOARDS: unlike other couch support options that use MDF or particle board, ours is made with premium .43” thick plywood that is naturally stronger and more durable; this heavy-duty couch board support for sagging seats can hold up to 400 pounds
- Stay in Place Grip Dots: designed to stay in place on sofas, this under couch cushion support features hundreds of slip resistant PVC dots on the underside; these grip dots help the couch supporter for under the cushions grip to sofa frame and prevent sofa board from shifting during daily use; individual couch board panels feature rounded corners to reduce chance of cover tearing
- Easy to Install: installation is simple and fast; simply remove the cushions from your sagging couch, unfold the cushion supports for sagging cushions, and lay them across the width of sofa frame with grip dots on the underside; add cushions back to sofa on top of support board
- Foldable and Stackable for Universal Fit: boards are available in standard sofa furniture sizes for a perfect fit, but can be folded and stacked to accommodate loveseats and smaller couches; we recommend measuring your sofa before purchase; measure your couch seat width from left inside arm to right inside arm; this support board measures 70 inches
