Inspired by the open kitchens at our favorite restaurants, we created this high-quality, hard-working and affordable cookware to use every single day. Our lightweight three-layer bonded stainless-steel cookware achieves the ideal balance of professional-level performance, classic style and modern-day practicality. Featuring a thick aluminum core for responsive, uniform heat transfer, these pieces brown and sear foods beautifully. The interior and exterior layers are made of top-quality stainless steel for durability and easy care. We've configured this essential set to include the pots and pans you'll use most often for both everyday cooking and entertaining. Designed and developed by Williams Sonoma, and exclusively ours. Aluminum core ensures impeccable heat conduction-no hot spots. Polished stainless-steel exteriors are durable and easy to clean. Nonreactive stainless-steel interiors promote efficient searing and caramelization. Stainless-steel handles are designed for optimal comfort and control. Stainless-steel lids circulate heat and moisture. Ideal for use on any cooktop, including induction. Dishwasher safe. Limited lifetime warranty.
