We have designed three different styles. all are made from strong 250-thread count, 100% cotton tick. The first style(style B) is divided into vertical channels and has square walls similar to a mattress. The second style(style C), which is the fluffiest looking, is divided into three horizontal compartments and finished with a knife edge. The newest style(style D), is a baffled box design with the mattress corners. It's designed to eliminate shifting. We then top it with it with white goose down comforter creating the ultimate in comfort and luxury.
