The Superior 400 Thread Count Long-Staple Combed Cotton Solid Duvet Cover Set is a simple, but dynamic, way to add a bit of pop to your too-familiar décor. A duvet cover and two matching pillow shams are included in this set (only one sham for the Twin and Twin XL sets). Each piece is made from 100% long-staple combed cotton and is available in your choice of available solid colors. Each piece is machine-washable. See below for duvet cover dimensions (size options subject to availability).
