DwellStudio offers stylish bedding for bigger kids. Featuring designs that are playful (but still grown up), their sheets and duvets are built tough to withstand everything from naptime to horseplay. Their kids bedding features stylish patterns - simple geometrics, pretty nature prints - with a timeless appeal, so they'll grow as your kids do! Twin Duvet Set includes one duvet cover and one tailored sham. 100-Percent Cotton. DwellStudio was born as Dwell Home Furnishings, in 2000. Founder and Creative Director Christiane Lemieux, a veteran of the worlds of fashion and home retail, wanted to offer the discerning customer a range of vibrant and modern textile designs.
