This all-season comforter features an innovative design with 2 layers consisting of a regular sized comforter and a smaller layer that can be removed. Box quilting prevents the fill from shifting. This set uses an antimicrobial treatment that prevents the growth of odor-causing bacteria. Such treatment helps keep the sleeper healthy, fresh, and clean while reducing the laundry needs. Active after washes, the anti-bacterial treatment keeps the linen long-lasting while maintaining the built-in freshness. This item is OEKO-TEX certified, meaning it does not contain any harmful chemicals and is eco-friendly. It is safe for direct, large-area, pro-longed contact direct to infants, kids, and even the most sensitive skin. 100% polyester Twin 2 Layer Comforter: 63x88"/63x68" Full/Queen 2 Layer Comforter: 88x92"/88x72" King/Cal King 2 Layer Comforter: 104x92"/104x72"
