Box Edge
A Box Edge or Box Corner cushion is constructed to hold the shape of a hard vertical line at the corners, forming crisp 90 degree angles. This technique is frequently seen on the seat cushions of sofas and non-recliner armchairs.
A box edge or box corner is a sewing technique that allows a cushion to have more loft and while keeping its crisp box shape. All of our chair pads come with a box edge to give them extra loft and shape.
