Custom Leather CushionsMade to order custom leather cushions. Leather is a natural product that ages much like wood. From the oil on your hands to the dirt, heat, moisture, and sunlight it is exposed to, leather absorbs the elements it interacts with. Your cushions will begin to incorporate this wear and parts of your cushion may begin to darken or develop a sheen. This change in patina does not affect the life or functionality of the leather.
