• To determine the correct foam size for your cushion, we recommend measuring the cushion cover itself from seam to seam .For the thickness, we generally recommend ordering foam approximately 1"–1.5" thicker than the seam-to-seam measurement. For the most accurate fit, we also recommend unzipping and opening your cushion cover and comparing the measurements to your existing foam insert before placing your order.
• Your foam has been compressed for shipping to help protect it during transit and reduce package size. Once you receive your order, carefully remove the foam from the packaging and allow it to air out and expand for 1–2 days. During this time, the foam will gradually return to its original size, shape, and thickness. For best results, place it on a flat surface in a well-ventilated area and avoid using or covering it until it has fully expanded.

• Measure and order — Measure your cushion cover from seam to seam, then order foam approximately 1"–1.5" thicker for a perfect fit.
• Allow foam to expand — Unpack the compressed foam, place on a flat surface, and let it air out for 1-2 days until fully expanded.
• Trim and install — Use a sharp knife or electric cutter to trim foam to size, then insert into your cushion cover for a snug fit.
