When sourcing white leather sofas, the material grade determines both price and longevity. Full-grain leather is the highest quality, offering natural breathability and durability, though it is the most expensive. Top-grain leather is more common for B2B orders as it is sanded to remove imperfections and treated with a protective finish, making it more resistant to stains—a critical factor for white furniture. Split leather or bonded leather should be avoided for high-end projects as they prone to peeling and discoloration over time.
