Replacement legs for a sofa are available at furniture stores, home improvement stores, and online marketplaces. Specifically, for the Feathers Collection, you can customize and upgrade your sofa with easily adjustable legs directly from the manufacturer. The Feathers Collection offers an option to upgrade from the standard 2-inch legs to 6-inch legs, enhancing the sofa's height without the need for tools. This option is available for the Feathers Collection 2.0 (February 2024), introducing a new product line for legs that are designed to be easily changed, allowing for quick customization from low to high.
