How to Make a Diamond Quilted Seat Cushion for an RV Dinette

In this tutorial video, we will show all the steps required to make a box cushion with a diamond quilted/pleated top plate. This cushion also includes a boxing that is continuous, meaning it has no seams on the front two corners. The cushion replaces a cheap seating cushion that was purchased for an RV dinette. Our cushion will utilize high density foam, which lasts much longer and won’t bottom out compared to a cheap low density foam. Use Sailrite’s Fabric Calculator to easily calculate the amount of materials required for your cushion. It also calculates the measurements of your plates, boxing and zipper plaque for your particular box cushion's desired size.
