“Our mission is to bring indulgence into bedrooms around the world.” St. Genève began as a small Canadian family business more than 50 years ago. Founder Michael de la Place was struck by the experience of sleeping wrapped in a European down duvet. At the time, duvets were virtually unknown in North America. The St. Genève line includes duvets, pillows, pillowcase toppers, blankets, and other gorgeous bed-related products.
Deeply committed to comfort, authenticity, and luxury, St. Genève is now world-renowned for luxury bed linens and quality down products. The bed linens are designed and made in Canada with top-quality silk, linen, and Egyptian cotton woven in Germany and Italy. St. Genève’s down has unsurpassed insulating power maintained by their high loft, density, and clinging properties, making them warm and lightweight.
