New outdoor furniture often comes with cushions that are surprisingly stiff and uncomfortable. This firmness is usually due to the foam being tightly compressed for shipping and storage. Fortunately, you don't have to suffer through a break-in period of sitting on hard cushions. Here are several effective methods to soften them up quickly and safely.
The simplest and most immediate solution is to physically manipulate the cushions. Remove them from the furniture and vigorously fluff them by hand. Knead the foam from the edges toward the center, punch them gently, and fold and flex them. This action helps to break up the foam cells, introduce air, and restore loft. For best results, do this daily for the first week.
Another powerful, natural tool is sunlight. Place the cushions outside on a warm, sunny day. The heat from the sun will make the foam more pliable, allowing it to expand. Flip the cushions every 30 minutes to ensure they heat evenly. Be cautious not to leave them in intense, direct sunlight for more than a few hours, as this can fade the fabric over time.
If the cushions are still too firm, you can use your own body weight to break them in. Place the cushions on a clean floor and walk or kneel on them, focusing on different areas. You can also sit on them repeatedly while they are on the furniture. This process mimics long-term use and helps compress the foam in a way that creates comfortable, body-conforming soft spots.
For a deeper treatment, consider using fabric softener. Check your cushion tags to ensure they are removable and the covers are machine washable. Add a cup of fabric softener to your washing machine's rinse cycle when washing the covers. The softener will relax the fibers, making the fabric feel less rigid against the foam. Always allow the covers to air dry completely before putting them back on the cushions.
With a little bit of effort, you can transform your stiff, new outdoor cushions into the comfortable, inviting seating you envisioned for your patio or deck.
